Tigo Energy TS4-A-S Module Add-On RSD Unit, Safety, 456-00252-32

Note: CCA Kit with TAP is required for rapid shutdown with TS4-A-S.

The new Tigo Energy TS4-A-S rapid shutdown solution is a cost-effective way to fulfill UL 1741, NEC 2014 and NEC 2017 requirements. It is compatible with the power line based SunSpec communication signal for a rapid shutdown, making it simple to implement with robust functionality. Using the existing DC wires between the inverter and module-level electronics as a communication channel significantly reduces installation time and labor costs, since no additional communication equipment is needed. The TS4-A-S compliance with the SunSpec open standard makes it the most flexible solution on the market, as it can be combined with multiple types of inverters.
