Mastervolt is a European company so the default is 230 single phase, they sell a US 120 volt version. Though I prefer Victron's inverters/chargers to Mastervolts they are both top notch inverters/chargers.
Most shore panels top out at 50 amps, so 50a x 120v = 6000 watts. So max charge current realistically is 6000w / 48v = 125 amp. So any charger over 100 amps would be hard to feed.
Most shore panels are 30a x 120v = 3600 watts. So 3600 watts / 48 volts = 75 amps. Which is why most boat chargers top out at 70 amps. That is the highest charger rate you can feed with a 30 amp shore panel.

Should I be looking at this product for an inverter/charger:
Mass Combi 48/5000-70 (230V) | Mastervolt Marine
I'm confused about the 230v output though. Does this mean I would further have to change that back to 120v somehow>=?
