Note:
AL1024NK8(D) power supply is designed to work with batteries up to 65AH.
Please note: line [I] must not exceeds 36AH.
You have to reduce either stand-by current consumption or stand-by time in order to comply with requirement.
To determine actual battery size please round line [J] to the nearest larger standard battery size
(e.g. 3.5 AH = 4.0 AH).
