I wish to fabricate a power supply that will power the whole house from a battery supply bank. I plan to use some large forklift batteries charged from solar wind generators. I need some technical assistance for choosing battery size voltage as well as a schematic for an inverter that will be capable to operate household needs from this battery bank. Also what is required to put unused power back into the grid. There are details I do not know of many other things I need to know. I would appreciate any assistance with this project. Thanks
I wish to fabricate a power supply that will power the whole house from a battery supply bank. What power consumption do you envisage, and for how long? Is it required to continue to work in a period of dull, windless weather - for how long? schematic for an inverter that will be capable to operate household needs from this battery bank. Also what is required to put unused power back into the grid. You need an approved inverter - you would not be allowed to use a home build to do this. From your rough details I'd expect this to be FRIGHTENINGLY expensive. Our 3.6kW solar panels deliver on average 10kWh. The average demand is 10kWh (we use gas for heating cooking etc) so on this basis your batteries would need to store about 10kWh. a car battery of 12V 100Ah can supply 12 * 100 * 0.7 (max efficiency) 840Wh so you would need 12 to store 10kWh. Cost per battery ?100
