This has come up for me recently, so it's >on my mind. According to an "Inverter comparison chart," supplied by West Marine Co. Maximum efficiency of the inverters they list range from 88% to 94%. All of the products that they list appear to be made by Xantrex, (Heart Interface, Trace Engineering and Statpower are all now owned by Xantrex making them probably the biggest manufacture of inverters). Many of these products have built in battery chargers. I don't know if the efficiency of the charging circuit is equal to that of the inverting circuit. I don't have efficiency data on chargers. If we assume that a good charger will deliver about 90% efficiency on the conversion from 120 VAC to DC, and a good inverter will deliver about 90% back to AC, you can expect to lose about 20% in conversion. I hope this helps put you in the ballpark regarding efficiency. Best of luck, Dave Do you Yahoo!? Yahoo!
