I have been noodling away on how to handle 30 AMP 120 volt service and I would think just activate one inverter/charger to charge at the 120V level and have a manual switch to active that second.
I.E. If driveway surfing only draw 15 amps on 120, if plugged into 30 amp service enable an additional 15 amp draw.
