Product Overview

Please contact for the proper hookup diagram for your generator.

Please include the generator make & model, inverter brand, & battery bank voltage.

Most Honda EXXXXXIS Series requires a Honda Inverter Cable A0396

Outback 48 Volt inverter systems that do NOT have a dry-contact option will require isolation relay (A0365) 

Note: Standby generators will not work with the GSCM or GSCM-Mini. Standby generators have their own control circuitry for monitoring utility power.  

The Generator Start Control Module-Wifi (GSCM-Wifi) is a fully configurable micro-processor based generator start controller that is designed to auto start and stop gas or propane generators. 

It supports three types of 3 or 4 wire gas-generator control:  momentary, maintained or key ignition.  It automatically disconnects the starter when a minimum generator AC Hz output is measured.  It has a adjustable crank time and over and under frequency shut down.  The GSCM-mini is powered by 12 volts DC from the generator battery and can monitor the battery voltage and start the generator to charge its own battery.  The GSCM-Wifi uses the generator AC output to know when the generator has stated and is running. 

The GSCM-Wifi also includes a third relay contact that can be configured to do one of several functions. Some of the functions available are a glow-plug start timer, acting as a generator power switch, a manual choke control, generator priming control, and a load control(by way of external load transfer switch)

The GSCM is also available in the original 2-Relay version and the 2-relay diesel version, inverter version or  the GSCM Rev. C programmable version.

Dimensions:  L: 5.5” x  W: 3.5" x  H: 2.0"
