A “three-wire-start” generator has two or more starting circuits. It usually has a separate switch or
position for cranking the generator. The AUX terminals cannot control this type of generator without
using a three-wire to two-wire conversion kit.
Atkinson Electronics (http://atkinsonelectronics.com) makes these kits, among other companies.
The Atkinson GSCM-Mini is designed to work with OutBack inverters and others.
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. (Note that it is
more common for the battery to be incorporated in the generator.)
