[RE-wrenches] KAUAI CHARITY CASE

[Dan Fink]

FLAs. Sounds like a bad candidate for NiFe.
NiFe does give you the extra DOD down to 80%, but can the inverter handle
the surge loads at such a low battery voltage? I have that issue with my
12vdc office system; I can really only go down to 50% DOD until the fridge
surge kicks the magnum inverter offline at night from LVD. Fine during
daytime of course.
