The first step of creating a TS4 system with module level monitoring is knowing your components.
Tigo TS4-M/S/O/L systems are composed of three components
|TS4, TS4-A||The TS4 Flex MLPE platform is a new generation of smart module, offering different levels of functionality and electronics built into a removable junction box cover. The TS4 is available as a PV module junction box or as an add-on device for standard PV modules.|
(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
|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. It is powered via 24V DC input.
NOTE: 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. The TS4-O and -L will optimize with or without communication equipment.
Below is a diagram illustrating how the various Tigo hardware components connect and integrate in a system:
The above illustrates the basic architecture. If you all you are looking to do right now is create a BOM for a project for pricing/quoting purposes, refer to the Tigo product selection tool and come back later to learn the details of the design process.
If you are ready to proceed with your design, review the below:
- Ensure availability of power and internet at the site - the CCA can connect via WiFi or ethernet
- Check TS4 lead length, particularly for landscape modules. If you are using 72 cell modules in landscape, make sure you have TS4's with 1.2m output cables.
- Check connector type for modules (MC4, etc) - ensure they all match
- Check string fuses – should be 15A for TS4
Having reviewed the above, note that with Tigo, you have the opportunity to save money with selective deployment - you don't need an optimizer on every panel with the TS4 solution. If you want to learn about the guidelines for using this technology, proceed to Selective Deployment with TS4.
If you already are familiar with Selective Deployment, or you are choosing not to use it this time, then it's time to learn how to place your TAPs.
