Three-Wire-Start
A “three-wire-start” generator has two or more starting circuits. It usually has a separate switch or
position for cranking the generator. A three-wire generator has fewer automated functions than a
two-wire. It usually requires multiple controls for starting, running, or stopping. The AUX terminals
cannot control this type of generator without using a three-wire to two-wire conversion kit.
Atkinson Electronics (http://atkinsonelectronics.com) is one company that makes these kits. The
Atkinson GSCM-Mini is intended to work with OutBack inverters.
The drawing below is one example of a possible arrangement. Specific arrangements, relays, and
other elements depend on the requirements of the installation and of the generator.
