Tigo Energy FAQs

PV-2.0

The TS4 solar module universal junction box platform enables you to choose the exact options you need for any given solar project or customer, from safety features to module-level diagnostics and maximized energy harvest. The TS4 universal baseplate can be matched with one of several TS4 covers containing the application electronics. Together they form a new generation of junction boxes; modular, flexible, replaceable, and upgradable, accompanied by a powerful PV 2.0 communication-centric architecture backend.

Long Strings TS4-L

The TS4-L is the complete smart module solution. It is ideal for systems requiring fully optimized performance at the module level,as well asmonitoring, safety, and longer strings. Fewer BOS components allow for faster installation and reduced SKU management.

String length increased by up to 30%

Fewer BOS components

Faster installation

Inverter optimization

Lower wire-losses

Plus all the benefits of Optimization

Optimization TS4-O

The TS4-O bundles the Tigo smart module features into one seamless unit for enhanced energy yield and increased design flexibility. TS4-O is ideal for roofs which are challenged by shading, but do not need longer strings. In addition to safety, monitoring, and PV 2.0 synchronization, TS4-O optimizes each module when shade drops their performance. With optimized modules, more roof space can be used to maximize energy production.

Shade and age tolerance

Enhanced energy yield

Greater design flexibility

Maximized roof usage

Doesn't require communication

Plus all the benefits of Safety

Safety TS4-S

For installations unencumbered by shading, the TS4-S provides the necessary safety and monitoring services to ensureyour systems meet local fire regulations, while also providing you and your customers increased insight into system performance.

Two Types of Communication

1. Flex MLPE - Wireless Communication

The first type of communication is wireless. See below. This is used with Tigo's TS4-M, TS4-S, TS4-O and TS4-L. These products can be mixed and matched in what we call Selective Deployment.

TS4-F/TS4-R-F Installation and Safety Manual

The TAP is like a Wifi hotspot. It communicates wirelessly with the TS4 units.

The TAP is connected to the CCA (Cloud Connect Advanced) by an RS485 communications cable.In a typical system, TAPs are mounted under the PV array, and CCAs are mounted near the inverter(s)

For more information on Tigo's wireless communication, see our article, " TAP and Mesh ".

2. PLC Communication - TS4-F

The second kind of communication is PLC (Power Line Communications). This is used with the TS4-F. The TS4-F does only rapid shutdown. It does not do module level monitoring or DC optimization. The TS4-F can not be mixed with the Flex MLPE products above. The TS4-F must be deployed on every module in the system.

This method uses a signal transmitted over the DC wiring. That signal comes from the RSS Transmitter.

The RSS Transmitter has a magnetic core. Either the positive or negative wire from each string passes through the core. This allows the signal to be transmitted on the DC wiring.

The Tigo RSS Transmitter has a range limit. The entire DC loop for each string, from the positive terminal on the inverter, out through the array, to the negative terminal on the inverter, should be less than 1000 feet (300 meters).

For more details on the TS4-F and the RSS Transmitter, see our ""

Online Site Configuration

Small systems can be set up and commissioned using the Tigo SMART Mobile App. For systems of 50 modules or more, we recommend doing online configuration using the Tigo SMART Website on a desktop PC. This will allow you to take advantage of the larger screen. See the video below for a basic walk-through of the Tigo SMART Website features for installers, including site set up and configuration.

Get Organized

If you are configuring a large system, it may help to make a spreadsheet showing the string assignments for each inverter, CCA and TAP. See the attachment to this article, "String_CCA_mapping.xlsx".

Site configuration requires having the bar codes of the Cloud Connect Advanced (CCA), and each of the TS4 units. Each Tigo TS4 unit will have two bar code stickers. See below. The one on the left is on the permanent product sticker. The one on the right is intended to be removed and placed on your paper system map.

https://smart.tigoenergy.com

Create a Paper System Map

This step is normally done when the physical installation is complete. This way all modules and TS4s should be in their final position.

Make a paper map - big enough to accommodate all of the bar code stickers without overlapping. See below for an example.

To enter the barcodes into the software, it is highly recommended to use a barcode scanner. A barcode scanner makes this work quick and typo-free! Any off the shelf barcode scanner will work. Many USB bar code scanners are available. They all function in a similar way and can be purchased for as little as $20 - $30 online.These USB bar code scanners act like a computer keyboard. They are very simple to operate.

Log In

Startwith logging in to your Tigo account by going to or register for a new account if you don't have one.

Once an account has been created, click on '+New System' at the upper right corner. See the video above, which will walk you through the basics of setting up a site in the Tigo SMART Website.

After you have created your layout and paper barcode map representing the physical arrangement of all the modules in your system, you can use the Uploader function to download a spreadsheet template customized for your system.

Now choose your spreadsheet download format. See below. Then click on Download.

Entering Serial Numbers Using a Bar Code Scanner

What you will need to complete this step:

Paper map showing bar codes for all modules

Spreadsheet downloaded from the Tigo portal (see below)

Bar code scanner

The spreadsheet you downloaded earlier should look like the following.

You can now use a bar code scanner to scan the paper map you made earlier. Plug the scanner into your computer. Click on the spreadsheet cell where you want to start scanning. Aim the scanner at the bar code and pull the trigger. Check that the bar code was entered correctly. The cursor will advance to the next cell automatically, as if you had pressed Enter on your keyboard. You can now scan the next unit in sequence.

Once the scanning is done, you can go back into the Tigo portal and upload the completed spreadsheet. See below.

When all barcodes are uploaded, commission your system using the Tigo Smart App

Purpose of the System Layout Design

In the System Layout is a graphical representation of the solar array is created. The geometrical arrangement of the Inverters, CCAs and Solar Modules in the created illustration should be representing the real layout of the solar array as close as possible.

The generated map of the solar array will be imported into the Tigo Internet Portal and is used to illustrate and monitor the performance and other relevant data on a modular level.

Additionally in the layout configuration the ID numbers of the optimizers are assigned to the module symbols in the map in the right order so at all times the displayed data can be associated to the right module in case of maintenance.

Tips and hints guiding you on how to complete the layout are going to appear once, and then disappear. To have the tips shown again log out of the app and log back in.

Placing the Equipment

Look at the solar system and make a draft sketch of how the system should be displayed so even somebody who is completely unfamiliar with the setup would understand it best

To place the objects you have to press the desired position on the grid.

On the bottom left is displayed which part of the equipment you are placing at this time.

On the bottom right you can choose which part of equipment you want place now.

You can have the whole system placed automatically

Check if the automatic placement has created a realistic image of the solar array

If something went in to the wrong place, you can undo the last step

Tigo is dedicated to flexibility, which is why our technology reads data from MODBUS RS-485 devices and other RS-485 devices. Please note the the majority of the devices listed here use MODBUSRS-485 communication, but a select few devices use other proprietaryRS-485 communication protocols.

If you are not sure where to go next, start by learning about TS4, Tigo's FLEX MLPE platform for increased ROI on your solar projects.

Why TS4?

One of the features of the TS4-O optimizer is PIV (Predictive IV). PIV means that the TS4 units can do full optimization independently without communication. See this article for details. This meansyou can install TS4-R-O units or optimizing Smart Modules without any additional equipment or configuration and they will maximize your energy production all by themselves.

You only need to install the TS4-R-O units or Smart Modules as indicated in our Interactive Installation and Safety Manual and Installation Training Video. You don't need to install or configure a Gateway or Cloud Connect. You don't need to do any online configuration or registration with Tigo.

Safety

Failure to adhere to the above installation steps in the above sequence can damage the product and will violate warranty.

This can also be done with Smart Modules. Smart Modules are solar modules sold with Tigo optimizers already installed at the factory. In this case there is nothing extra that needs to be done. Install the modules as you would any other, and the power optimization (PIV) will work without any additional equipment or configuration. Smart Modules must have the optimizing feature of the TS4 for this to work.

If you do not install Tigo communication equipment, you will not be able to see module level monitoring.You will also not be able to use thefeatures of the TS4. If you are doing a retrofit, however, you should see the production difference in your system level monitoring.

PIV is just one of many features of the TS4 that give youthe ultimate in flexibility. PIV and Selective Deployment allow you to make the most of your solar installation at minimal cost.

The power supplies for both the Cloud Connect and Cloud Connect Advanced draw less than 1A, so these can be installed on minimally sized (10A or more) circuits. For feeding wires serving a 10A circuit and the DIN Rail Power Supply, use code compliant conductors derated for your conditions. (NEC 310.15 in the USA). For the wires going from the DIN rail power supply to the CC(A) unit inside the provided enclosure, use AWG #20 or larger wires.

Opening and Closing TAP TAP (Tigo Access Point) Gateway (black housing)

Gateway (light gray housing)

The TAP and Gateway are Tigo's wireless antenna, TAP being the new and improved model. The TAP allows communication between the Cloud Connect Advanced (CCA) and our TS4 optimizers.

The Gateway has a similar function to the TAP. The Gateway is Tigo's legacy wireless antenna.

TAP vs. Gateway:

Ease of installation:

TAP has a larger wiring compartment

TAP has designated CAT 5/6 terminals for easy wiring

Fewer TAPs are required on a system; easier to install

Time and Money savings:

Fewer TAPs are required on a system; faster to install, fewer components

TAP has larger cable glands that fit a larger number of RS485 cables

More information:

For instructions on installing either TAP or Gateway, see our Interactive Installation and Safety Manual. For further information on the Gateway, see Gateway Placement, and for information about TAP placement, see TAP Placement.

For more information concerning design and installation using TAP or Gateway, see the articles Determine Number of TAP and Cloud Connect Units and TAP and Mesh.

The attached pdf document describes the protocol used by the Tigo Energy API. The API (applications programming interface) allows performance data to be accessed and downloaded programmatically, for those customers who wish to develop their own clients. Note that API access requires an upgraded subscription package.

A communication cable is used to connect the Cloud Connect Advanced (CCA) with the TAP (Tigo Access Point) or Gateway.

"TAP" and "Gateway" serve the same function, TAP is the latest version of Tigo's communication antenna, and Gateway is the previous version. For Gateway requirements, see the article: Gateway Communication Cable. To identify which device you are using, see TAP vs Gateway.

TAP & Gateway Cable Requirements

4 conductor communication wire.

Minimum conductor size 22AWG (0.33mm)

Maximum cableoutside diameter (OD) of 0.35 inches (9 mm)

See also the article Opening and Closing TAP.

Depending on type of raceway/conduit in use and local jurisdiction requirements the cable may also need to be:

Outdoor rated and/or UV resistant and/or direct burial.

Notice: it is typically easier to find these type of cables when searching for non-shielded cables, however both shielded and non-shielded cables can be used.

See the Interactive Installation and Safety Manual for guidance on connecting the cables to the CCA and TAP.

Recommended Cables

For thecapability to run the TAP/Gateway cable in the same conduit as PV wire, Omni Cable's 600V 18AWG 4-Conductor Tray Cable, P/N A21804 or Omni Cable's 600V 18AWG 2-Pair Tray Cable, P/N L21802 isrecommended. This eliminates the need for the installation of a separate conduit for the TAP.

Using CAT5/6 Cables

On residential systems, outdoor rated CAT5 cable can be used to make the connection between the CCA (or CC or MMU) and TAP(s)/Gateway(s). See the table above for run length guidelines. With TAP, there are two options for CAT5/6 cables, triple twisted leads or the TAP quick connectors.

On commercial systemshowever, using outdoor rated CAT5 cable is not recommended ascable lengths generally tendto be longer (see details in the table above).

Using CAT5 cables for more than two TAPs or longer runs (triple twisted leads)

Opening and Closing the TAP

If you are using more than two TAPs or your runs will be longer than the limits in the table for the quick connectors, use the method shown above where three CAT5/6 wires are twisted together for the positive and negative leads. Use the terminal blocks only for this type of CAT5/6 wiring, not the quick connectors described below.

Using the Designated CAT5/6 Quick Connector Terminals in the TAP

For small residential systems with up to two TAPs, the designated quick connector terminals can be used with CAT5/6 wiring without stripping the ends. This method may be used for up to two TAPs in a chain or system. If you have anything more than that, you should use the terminal blocks and twist 3 wires together for each of the positive and negative leads as shown above. The remaining two leads can be used for the A and B signal terminals.

The quick connectors in the TAP are designed for 20-32 AWG wire. Do not attempt to use them with anything larger than 20 AWG wire. Use the main terminal blocks for anything larger.

First, cut 3cm (1-1/4") from the outer sheathing.

Next, open the TAP and identify the terminal block that will receive the connections.

Now remove the terminal block. If you need to, you can pry it gently with a screwdriver and a twisting motion.

Next, put the CAT5 cable through the gland. Feed the wires past the terminal block posts.

Now use a screwdriver to push the leads into the quick connector terminals. Push one lead into each terminal.

Push the remaining leads into the quick connector terminals. Tighten the gland and closethe TAP. Here are instructions for .

Rapid Shutdown Notes: For an off-grid installation to support rapid shutdown, power your CCA/CC (Cloud Connect Advanced/Cloud Connect) via its own power supply with a switch. Then to shutdown the system's modules:

Switch off/disconnect the CCA from its power supply

Turn off the charge controller.

The above two steps will send the system into shutdown mode.

Note: if you require Rapid Shutdown in an off-grid system, you should have Tigo's Mesh software on your system. You can verify this by sending a request to "[email protected]" with your system ID.

To reactivate the system after rapid shutdown:

Switch on/reconnect the CCA to its power supply

Turn on the charge controller

The above two steps will bring the system's modules back online.

If you have updated your preexisting WiFi network, you will also need to update this information on your CCA. Otherwise, your CCA will not be able to upload the newest module-level data and you will not know how your Tigo system is performing.

In order to reconfigure your CCA you will need the Tigo SMART App and you will need to be close enough to the CCA to connect to it.

Open up your Tigo SMART App and log in, if you are not logged in already. Find the system you need to reconnect.

https://www.tigoenergy.com/contacts/

Tap on "Settings," then on "Cloud Connect Settings."

Connect to the CCA. The simplest way is to connect via Bluetooth, but if you have issues with this, you can connect to the CCA WiFi network. (Note, if you do not see the Bluetooth or WiFi network, please reset the CCA and wait a few minutes for it to reboot. You can then try again.)

Once connected to the CCA, press "Next." Tap on "Network."

Tap on your network name and enter the password.

Tap on the exclamation mark (!)next to the network and tap on "Run Network Test." This will verify that the CCA is properly connected to a network and able to transmit data.

Once you have verified that the CCA is properly connected to the network you can exit the app.

Depending on your system size, how long the CCA has been offline, and your network speed, it may be an hour or more for the data to update online.

If you run into issues please contact our support team. Their contact information can be found here;.

If you need to set a static IP on your CCA, you can follow these steps to do so.

Note that this is only possible on an Ethernet connection. This will not work with a CCA on a WiFi connection.

Open up your Tigo SMART App and log in, if you are not logged in already. Find the system you need to configure.

Tap on "Settings," then on "Cloud Connect Settings."

Connect to the CCA. The simplest way is to connect via Bluetooth, but if you have issues with this, you can connect to the CCA WiFi network. (Note, if you do not see the Bluetooth or WiFi network, please reset the CCA and wait a few minutes for it to reboot. You can then try again.)

Once connected to the CCA, press "Next." Tap on "Network."

Once in the network configuration you want tap on "Ethernet" thenon "Manual."

You will see all the fields that need to be configured. This information is specific to your network. Enter the appropriate information in each field.Once the information is entered, tap on "Join." The CCA will then use that information and connect to the network.

If you have issues connecting to your network, please verify that the IP, Subnet, Gateway, DNS1, and DNS2 are correct. Also verify that the network you are connecting to is operational.

The TS4 product line is designed to give the user maximum design flexibility at any given price point. If optimization and shade mitigation are not needed in a given project, TS4 offers a lower cost solution to fit the design and budgetary needs of the customer, instead of a one-size-fits-all optimization solution. For more information regarding designing with TS4, please see our TS4 design notes.

Selective deployment is a feature unique to the Tigo TS4. With Selective Deployment, different features can be used together inthe same system using different TS4 versions. This allows you to deploy only the features you need, where you need them, lowering costs and increasing ROI in your system.

Here is an example, see Figure 1 below. We need module level monitoring and rapid shutdown, so we deploy TS4-S on the entire system. But, we have shading on the two right-hand modules. So, we can deploy TS4-O on those two modules only. Since the TS4-O also does module level monitoring and rapid shutdown, we now have all the features we need, but we have saved money by only deploying the more expensive TS4-O on the shaded modules. Since we are deploying module level monitoring and rapid shutdown, we will also need Tigo's TAP and CCA for communication.

Different Orientations

Figure 1: Rapid shutdown compliance plusdeployment of optimization only on shaded modules

Selective Deployment of Optimization using Predictive IV

Predictive IV is a unique feature ofthe TS4-O, which uses electrical properties of the module itself to predict optimal performance conditions.This data is used in conjunction with Tigo's impedance matching technology, and allows for selective placement only on shaded modules even without communication. Using this feature, we can deploy TS4-O units on under-performing modules and no other equipment whatsoever. See also Installing TS4 Without Communication for further details.

Selective Deployment of Optimization

When using a single string per MPPT, optimization can be selectively deployed only on the shaded modules (using TS4-O). By using optimization only where needed, you can optimize system performance at a lower cost.

Dual MPPT inverters can have astring with selective deployment of optimization on each MPPT.

With parallel strings on the same MPPT input, use 100% deployment of optimization (TS4-O).

Partial deployment of optimization on parallel strings is not supported. Use full deployment on parallel strings.

The Tigo Product Selection Tool allows you to determine a Bill of Materials (BOM) for your project. See this link for the tool.

The communication/control circuits of the TAPs and Gateways associated with Tigo Optimizers and Smart Modules system fall under the following NEC Articles:

NEC Article 300, Wiring Methods and Materials

Article 690, Solar PV (Photovoltaic) Systems

According to NEC Article 300.3(C) conductors can occupy the same raceway or conduit so long as they have the same insulation rating. Therefore, you may install TAP or Gateway wire in the same conduit as PV string homeruns as long as the TAP wire has the same insulation voltage rating as the homeruns.

Supplementally, article 690.31(B) allows conductors to occupy the PV array raceway provided they are an associated system.Since gateway communication cables are associated with the rapid shutdown capability of PV arrays using Tigo,they are allowed to share a raceway with PV wire.

The most common wire type that meets these requirements is Instrumentation Tray Cable (ITC). Ensure that the nominal outside diameter is less than .35 inches (9 mm).

NEC 2014 and 2017 code requires PV systems tohave arc fault circuit interruption (AFCI) protection. AFCI protection is achieved by detection of an arc and immediate DC shutdown, at the string, combiner, or inverter level. Being module-level devices, Tigo MLPE do not have AFCI and cannot detect an arc, but some types can help mitigate damage. Some inverter manufacturersand other third-party devices have implemented solutions into their products,however some solutions experiencefalsedetection known as 'Nuisance Tripping'.

There are 2possible triggers for AFCI, resulting in DC disconnect:

Actual arc detection

False trip due to noise on the DC line, incorrectly interpreted as an arc.

Research by Sandia National Laboratories identified multiple causes of nuisance tripping, mostof which were unrelated to optimizers. A detailed report is available here.

Tigo's TS4 line of product can be divided to 2 groups when it comes to external AFCI devices:

TS4-D, TS4-M, TS4-R-M: these units are 100% passive and behave just like standard modules, therefore they don't have any effect on AFCI devices whatsoever

TS4-S,TS4-R-S, TS4-O, TS4-R-O, TS4-L, TS4-F and TS4-R-F: these units are not passive, and therefore are being thoroughly tested for compliance

As of February 4th 2019, Tigo has identified the following combinations:

Identify your Tigo Data Logger

There are three data loggers available from Tigo:

Cloud Connect Advanced (CCA)

Cloud Connect

Management Unit (MMU)

Legacy Product

Identifying Your Networking Equipment

Routers and Modems

In most locations, internet access is done with a router or modem which will look something like this:

or this:

Locating this equipment will make it easier for Tigo Support to help you if you're having problems.

Power Line Adapters

Power Line Adapters (PLAs) are often used when Wifi signals are weak or cannot penetrate walls or ceilings. They really just extend an existing ethernet network.

Data Logger Connection

Your data logger (see above) will be connected to your network via one or more of the following methods:

Wired (ethernet)

Wireless (Wi-Fi)

Power line adapters

Only the Cloud Connect (CC) and Cloud Connect Advanced (CCA) can connect wirelessly via Wi-Fi. All can use a wired connection.

Here is an example of a CCA using a wired (Ethernet) connection:

Here is a diagram of a wired (Ethernet) network connected to Tigo equipment:

Here is an example of a CCA using a wireless (Wi-Fi) connection:

Here is a diagram of a wireless (Wi-Fi) network setup:

If both the ethernet cable and wifi antenna are present, the ethernet wire will be used if it is connected. If it is connected, you will see lights (LEDs) blinking near the connector. Otherwise the Wi-Fi is likely being used.

Power Line Adapters

Power Line Adapters extend your network using your building electrical wiring and outlets.

Tigo Support will be able to help you much more quickly if you take a few moments and gather information about your network. If you are not getting all of the data you expect, chances are good that there is a problem with your network.

The TAP (Tigo Access Point) is a wireless antenna that allows communication between the Cloud Connect Advanced (CCA) and the TS4 optimizers.

A Tigo-optimized PV system consists of four key components (also see below):

Cloud Connect Advanced (CCA)

TAP

Smart Modules (or other Tigo-equipped modules)

Inverter

The number of TAPs and Cloud Connect Advanced units needed for a system are determined by both the number of modules and the size and layout of the installation.

Opening and Closing TAP

The TAP is Tigo's latest wireless antenna. It replaces the Gateway wireless antenna. For the differences, see our article TAP vs Gateway.

TAP basics

Up to seven TAPs can be connected in series to each Cloud Connect Advanced using RS-485 cable (not included.)

Each TAP can communicate with up to 300 Tigo TS4 units, or up to 600 PV modules if equipped with TS4-R-Duo units.

With the TAP, the TS4s act as repeaters. For the signal to hop, the TS4s must never be more than 10m (33ft) apart. So, if there is a gap between modules, make sure the gap is within these limits. This is shown below with the green arrow.

The range of a TAP, with hops, is a maximum of 115ft (35m) line of sight. If modules are located more than 115ft (35m) from the TAP, or if there are physical obstructions throughout the array such as HVAC units, or roof gables, use additional TAPs.

For best results:

TAP needs to be placed within 33ft (10m) of at least five TS4s

Allow 50ft (15m) line of sight spacing between TAPs

Place TAP near the center of the array

Below is an illustration of the hop distance between the TAP and optimizers.

Below is an illustration of the range and scale of a TAP/Mesh layout, using average 60-cell size modules. In this example, there are over 500 modules within range of the TAP, much more than the limit of 300 per TAP. Since this array is 560 modules, we would need two TAPs. As you can see, we would have a lot of freedom in placing them.

For a more complete understanding of how TAP works, see our article TAP and Mesh.

For instructions on installing TAP, see our Interactive Installation and Safety Manual.

For more information concerning design and installation using TAP, see the articles Determine Number of TAP and Cloud Connect Units.

Description

TS4, TS4-A

Products

The TS4 Flex MLPE platform is a new generation of smart module, offering different levels of functionality andelectronics built into a removablejunction box cover. The TS4 is available as a PV module junction box or as an add-on device for standard PV modules.

TAP

(Tigo Access Point)

TAPs are antennas that communicate wirelessly with smart modules and relay data to the Cloud Connect Advanced via an RS-485 or CAT 5/6 communication cable.

Cloud Connect Advanced

(CCA)

The Cloud Connect Advanced (CCA) provides module-level data logging and safety capabilities for an array of smart modules. It also features built-in Wi-Fi and can be commissioned using a free smartphone app for iOS or Android devices.

Below is a diagram illustrating how the various Tigo hardware components connect and integrate in a system:

For systems using TS4-O and/or TS4-L modules, TAPs and CCAs are required only if monitoring and/or module level shut down is desired.

These are the three components, but how many do I need for my system? Read " Determine number of Cloud Connects and TAPs " to proceed.

Visit the page for more info.

Overview

The number of TAPs and CCAs needed for a system is determined by both the number of modules and the size and layout of the installation.

Do I have TAP or Gateway?

TAP is a new iteration on the Tigo Gateway. To determine if you have TAP or Gateway, see below and our article TAP vs Gateway.

The maximum number of TAPs per CCA is 7.

The maximum number of TS4 units per CCA when using TAP is 900(when using the TS4-R-Duo, max number of panels per CCA is 1,800).

A TAP can communicate with UHD-Core TS4 that are within a maximum line-of-sight radius (no obstructions) of 115ft (35m). If there are TS4 units more than 115ft (35m) away from the TAP, use more than one TAP.

See our article TAP Placement for more information.

Determine Number of Gateways (Legacy)

The maximum number of Smart Modules per Gateway is 120, and the maximum number of Gateways per Cloud Connect unit is 7. The maximum number of Smart Modules per Cloud Connect unit when using Gateway is 360.

A Gateway can communicate with Smart Modules that are within a maximum radius of 50ft (15m). If the Smart Module is More than 50ft (15m) away from the Gateway, use more than one Gateway.

See our article on Gateway Placement for more information.

Determine the Number of CCA (Cloud Connect Advanced) Units

All modules in the same string must be assigned to the same CCA.

All strings on the same string inverter must be assigned to the same CCA.

Refer to the Tigo product selection Tool to calculate your actual number ofTAP/Gateway and CCA units needed, as well as the maximum number of Smart Modules per string for your inverter.

Cloud Connect Advanced is available as a kit for indoor or outdoor use, refer to the Select Your Cloud Connect Unit article to choose the kit that fits your project.

Designing a system to meet rapid shutdown with TS4-F/TS4-A-F is easy

How it Works:

When your RSS transmitter is powered on, the RSS core in each RSS transmitter sends a pulsed signal to the TS4-F/A-F units in the system over DC wiring.

When your RSS transmitter is powered off, this signal disappears, and each TS4-F/A-F unit goes into shutdown mode, reducing voltage within the array to under 80V within 30 seconds.

How to Start Your Successful Design

Add one TS4-F/TS4-A-F to each module in your system.

Purchase RSS-integrated inverters from Tigo's Preferred Partners (such as the SMA Core1-41, Solectria PVI 50/60, Chint KTL 50/60, Fronius Symo Advanced, others) or useone RSS Transmitter Core for each 10 strings

[email protected]

Design considerations for external RSS transmitters

(skip if you are using an integrated inverter)

Powering your RSS transmitter

Each RSS transmitter is powered via 12V DC input.

The RSS transmitter can ship from Tigo and its distributors with either a 120/240V AC power supply or 277/480V power supply. Choose what works best for your application.

How many RSS transmitters do I need? (for C&I projects)

See Tigo's "Product Selection Tool" for assistance

How long can my DC loop for each string be?

The entire DC loop for each string, from the positive terminal on the inverter, out through the array, to the negative terminal on the inverter, can be up to 1000 feet (300 meters).

For more information, check out the installation manual by clicking here.

If you have design questions, feel free to email .

And last but not least, if you are done designing, congratulations! The next step is installation and commissioning.
