Product Overview

Here is a list of the hookup diagrams for various generators. There are 4 icons to the right, click on “Bookmarks” to find a list of generator hookup drawings.

If you do not find your generator, please contact for the proper hookup diagram.

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


Honda EXXXXXIS Series requires a GSCM-mini-i

Outback 48 Volt inverter systems 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-mini (GSCM-mini) is a non-programmable 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 fixed 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-mini uses the generator AC output to know when the generator has stated and is running.   

The GSCM-mini is also available in a mini diesel version, inverter version or a programmable version.  

Europe, Australia & Japan please see GSCM-mini-50Hz.

Dimensions:  W: 3.2” x  H: 1.2" x  D: .875"

    Generator Automation Champ

    Posted by Thomas Landers on Nov 11th 2023

    "Its alive!" Having a fully automated offgrid power system is something amazing. If there is not enough sun the CGSM-MINI takes over and starts the generator to charge the batteries for a few hours. Then turns it off all on its own.

    Works flawlessly!

    Great product and great support. Works perfectly with my Onan 5500 and Victron CerboGX. Now I can use a more accurate state of charge for auto start instead of just battery voltage.

    Used in 5th Wheel

    Posted by Rich Pflederer on May 25th 2021

    My 5th wheel has an inverter & residential fridge and on long drives I have to watch my battery drain, to solve this I install the GSCM-MINI-60HZ to auto start my generator when my battery back level falls to below 50% of charge. Installation following the provided instructions went very well. Solves my problem and I don't have to worry about ruining my batteries.

    GSCM-MINI Generator Start Control Module

    Posted by Bill's Service & Repairs, LLC on Feb 9th 2021

    We own a generator sales and repair shop in Colorado, and have purchased several of these modules from Atkinson. They arrive quickly, they work beautifully, and customer service is always friendly and professional. There's no reason to go anywhere else!

    10+ yrs experience with this product

    Posted by ChuckD on Jul 25th 2019

    I am adding 2 wire start to yet another generator. I have been using the GSCM-mini and its big brotherGSCM for more than 10 years. It's reliable at -10F and 100F. Excellent solution to converting most 3 wire start generators. So far, I have used the GSCM devices to a Yamaha (converted to LPG), Honda (gasoline) and a Champion (duel fuel) generator with great success. I highly recommend this family of devices.

    Technical Service Support Second to None

    Posted by Larry Carbary on Aug 29th 2017

    Product works as expected. The knowledgeable service and support of Abner Jenkins was the key to success. Abner provided advice, instruction and technical manual publications that make the installation easy and successful. This allowed the installation of an existing propane fired generator to be hooked into a new solar off grid system. The exact product for the purpose.

    Saving my bacon!

    Posted by Unknown on May 1st 2017

    Was so glad that this product has been developed as a way to connect my generator to my inverter/charger for my off grid solar power system on my home. Works great and the team at Atkinson were prompt and helpful with questions about installation.
