Larry, I have not found a battery charger nearly as programmable as the chargers in inverters are, and I've sold a number of inverters over the years which were destined to be used strictly as battery chargers.
This is actually a great use for modified-square-wave inverters. The Magnum RD2212 has a 110A charger section, and is relatively inexpensive. I doubt that you would find a better deal, even with the added cost of the Magnum remote unit you will need to program it. Magnum has smaller 12V inverter/chargers too, of course. Also a great use for old Trace SW inverters, if you can find an SW2512. I measured the charging efficiency of an SW4024 once and came up with 72%. Not bad at all, for a battery charger.

I have been needing this product for many years but I can only find it in inverters with built in chargers from Magnum, Outback, and Xantrex. -- Thank you, Larry Crutcher Starlight Solar Power Systems _______________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.htm l List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org
