I am hoping to meet the demand it shouldnt be to hard with enough batteries, and ive looked into inverters and the best ones to go with is a true sign wave inverter which will give more better power supply to newer electronics than a regular inverter. I beleive my alternator can put out anywhere from 70-120 amps. Not to sure of what kw im using but it shouldnt be to hard to maintain, and yes i have alot of water on my property that we supplie up to 15 other homes off of a gravity fed system and on a 1" pipe or garden hose im getting atleast 70-90 psi which can be upped by a power spraying nozzle that will be chocked down.
