Installation Guide

SYSTEM OVERVIEW: TS4-F

1. Modules with integrated TS4-F

2. RSS Transmitter and RSS Core

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.
