I would try to find a way to get off 110AC as using an inverter you are going to loose some of your power in the conversion. Not sure what all you are running, but there are some real nice LED lights and flourescent lights that sip power and will run for days on a good battery bank. A 12v device on a 12v battery will always be more efficient than a 110v device on a 12v to 110v inverter as no inverter converts 100% of the energy. Most good ones run 80-90% however.

Wait...... I just re-read your post and you said "converter" not "inverter". Are you talking about the battery charger (also called a converter/charger by some)?
Its an inverter....sorry. Thanks
