This article covers our FLEX MLPE products which feature wireless communication. We also offer the TS4-F which uses a different communication protocol (PLC) for Rapid Shutdown. See our article, "Application: Module-level Disconnect for Safest Solar" for details.
TS4-A is an add-on product that can be used with any compatible PV module. Refer to your module datasheet for voltage and current parameters.
The functionality of the TS4-A covers is incremental. For example: TS4-A-S includes the functionalities available with TS4-A-M, and TS4-A-O includes the functionalities available with TS4-A-S and -M.
Monitoring
TS4-A-M
- Same string design rules as traditional modules
- Can be selectively deployed on any system size, in order to provide module level monitoring
- Wireless communication for module-level data reporting
- Monitoring capability requires Cloud Connect and Gateway for communication (see Design Tool)
- A module equipped with TS4-M can be upgraded to any other TS4-R cover
Safety
TS4-A-S
- Same string design rules as traditional modules
- Compliant with NEC 690.12 Rapid Shutdown requirements
- Safety capability requires Cloud Connect and Gateway for communication (see Design Tool)
- Systems requiring safety functionality, such as rapid shutdown, should have TS4-S or higher on ALL modules.
Optimization
TS4-A-O
- Equipped with Predictive IV technology for selective deployment
- Enables uneven strings and different orientations
- Design into shade for maximized roof usage and design flexibility
- Compliant with NEC 690.12 Rapid Shutdown requirements
- Doesn't require communication accessories, unless monitoring and/or safety capabilities are needed (see Design Tool)
