I have been working with a system of 3KW xantrex inverter/chargers coupled with 4 12v deep cycle batteries to power pet grooming vans. batteries are charged at night by being plugged into the grid, and by day through a big inverter on the van. They have worked all day every day for 2-3 years with no major prob;ems.
