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.

    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

    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.

    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.
