SYSTEM OVERVIEW: TS4-F
1. Modules with integrated TS4-F
2. RSS Transmitter and RSS Core (integrated in CPS 25/50/60kW inverter
Tigo RSD wire-boxes)
3. Inverter

The TS4-F requires a Tigo RSS Transmitter or inverter with built-in transmitter for
operation.
The Tigo RSS Transmitter is installed in line with a solar PV inverter, as shown, and
can be installed inside the inverter or external to it.
Method of Operation
All TS4-F units start in the OFF position and measure 0.6V at the output. When
power is supplied to the RSS Transmitter, the TS4-F units turn ON and allow full
PV module voltage.
The units constantly receive a “keep-alive” signal from the transmitter over
PLC. When power to the transmitter is cut, this keep-alive signal ceases,
sending every TS4-F into shutdown mode with output reduced to 0.6V.
