The combination of a 12V inverter and 120VAC battery charger need not
be inefficient - it is dependent upon the efficiencies of the two
parts.

I am charging my batteries using a solar panel and voltage regulator.
Usually, I can recharge the batteries after landing using the remaining
daylight. If not, it easily recharges in the morning. I use this
combination of solar panel and regulator:
