TS4-A Design Notes

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)
