I will be installing the multiplus-ii 12V 3kVA 2x120v along with 2 lion UT-1300 batteries anything special to know with this config?? Also what about using the second 12 charge connection for a L/A flooded battery to charge it for the Gen. starter battery??? The Gen is onan 5.5K LP and later how to have the gen auto start to charge Batteries and the auto off once done??
