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-Wifi 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. 

The GSCM-Wifi is able to broadcast a Wireless 2.4GHz Wifi network that can be connected to with a phone or tablet in order to change the configuration settings. 

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-Wifi 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"

    Great company!

    Posted by Mike on Feb 2nd 2024

    This unit hasn't been installed yet, but previous units have worked flawlessly, and this one was easy to purchase, and Abner communicated directly and quickly with me to get wiring schematics and to go out of his way for my specific shipping needs. Thanks!
