Jeff: Can your client maintain batteries? The IBE 85N-13 is 627 AH of FLA. One string is too small, two strings is too large, so you may need to keep looking. I would add that we have had only one failure in 20 plus years of use. The MK-8A8DLTP Deka is 245 amp hours of AGM. Three strings

Howie: I don't know about the Island, but Outback does not have generator support -- the XW does. For occasional high load situations, this feature will allow a somewhat smaller generator sizing. Please do not confuse generator support with generator remote start. We have installed a 1 a 2
