If it's going in a cold climate, the Cummins RS generators absolutely require a coolant heater which is a significant AC load. Otherwise, they don't require any AC power but they do need their battery to remain charged. For this reason, they do come with an integrated charger, but if you have a more efficient charger then you can leave the 120V AC input on the gen set disconnected and just hook up the better charger. There's plenty of space in the generator enclosure for an aftermarket charger. Or if you have a good spare 12V solar panel laying around with a charge controller, then you shouldn't need to use a 120V charger at all 😉

Onan also has one as well. Are there any other make/models that people would recommend or would caution me against?
