Hopefully a simple question, I'm just getting started
I'm considering a 48v system for an RV. Primary need for 48v is to run the Hotspot heat-pump (which runs directly off 48v).
I would also like to be able to charge batteries from 120v connections (regular 15amp plugs, and very often 30amp 120v connections via the TT-30 connector), we almost never stay at 50amp 240 sites.
I'm looking at the all-in-one 48v boxes from MPP, Growatt, and Victron. Often they seem to specify, for their chargers, AC input above 120v. e.g., "Input voltage range: 187-265 VAC" Does that mean that they can't charge from 120v sources at all?
Is it possible to use these all-in-one 48v boxes with 120v AC connections for charging? If not then what other route to a 48v RV system that does permit 120v charging?
