Before you go anywhere you need to know what the draw on this motor is.

I have not been a fan of any Generac brand generators, especially their
low-cost, highly marketed residential stand-by generators. Although things
may have changed, these were very hard to use with a typical inverter's
2-wire remote start relay, most warranties were voided if used in off-grid
I can't answer your questions directly, but for the record, if you need
help with the two wire start issue, call Generac and ask for Bob Cramer. He
will send you a conversion kit and instructions for residential propane

I might caution against using the HBX mode for two reasons:
1. The batteries will wear out in proportion to the number of cycles. If
you don't need to cycle then I recommend you don't.
2. HBX can be a very inefficient mode. If you HBX cycle frequently then
