Heat pump use on battery
Question: Can I run my heat pump on battery?
Answer: Probably not. We assume your heat pump is part of a combined unit with your air conditioner. We have two roof-top AC/heat pump units. Our RV is not even wired to allow us to try run them off the battery/inverter. If we are boondocking and need to use the AC or heat pump, we turn on our generator.
It’s likely that your RV is not configured to allow running the AC/heat pump from battery power. Even if you can do it, it would probably deplete your battery bank very quickly. But who knows, perhaps your RV is non-typical in this regard. If so, we suggest you contact your manufacturer for their take on the subject.
