Inquiry (采购产品): battery backup system Hi, I'm putting together a cost est. for off-grid 40 kw gen-set 120/240 1 phase, with a battery backup system. If I use 20-200ah batteries and have a load of 12kw, operating time would be approx 1.5 hours. Is this correct? Roughly what would the cost be for 12volt 200 ah sealded lead acid batteries. Would it be advisable to to higher voltage?
