Mark The smallest battery I have used is the Blue Planet 8 kWhr. its a half stack in there cabinet with a 10.8 k PS-3 inverter system with about 6 k on the roof, 8 K is not much but this particular customer only uses this for some low demand power consumption that must operate. It is less expensive to go with 16 kWhrs vs 8 at a cost per watt also Jerry
