Intended Use

The TS4-R-F Rapid Shutdown solution is a cost-effective way to meet the requirements of the

 2014 and 2017. The TS4-R-F is compatible with the

powerline-based Sunspec communication signal for Rapid Shutdown. The signal is easy to
implement due to its reliable functional ability. The communication between inverter and module
electronics is done via the DC conductors. The installation times and labor costs are reduced since
no additional communication product is required. The compliance with the open SunSpec standard
makes the TS4-R-F a flexible solution since it can be combined with various inverters.
