hey fellow freepers, I need some advice.
I'm trying to set up a small solar panel system in case the grid goes down. I know I won't be able to power the whole house, but I want to be able to run a 750 watt deep well pump, a couple of 40 watt lights, a ceiling fan or box fan, cb base station and maybe a small freezer/refrigerator. I've got a 12v 100 watt solar panel, a 2000w 12v pure sine wave inverter and a 200 amp hour agm battery. Plus a 30 amp charge controller.
Will this be enough? I'm mainly concerned with making my battery last as long as possible and not kill it with undercharging/overcharging since these suckers are expensive.
I'd like to hear your thoughts and suggestions! Thanks
Bump - working on same, need to find this later
Thanks for that. We do have a backup 7000 watt generator as our emergency electrical energy source, and maintain about 20 gallons of fuel, but often rotate it through our other equipment to keep fresh as much as possible.
Will look up these resources you posted.
I determined that the locked rotor code on my pump is M. So if I read it right, that means the inrush current at 120v is 93.25 amps (11.19 * 1000 = 11,190 / 120 = 93.25) But if I’m running the motor at 12v, does it go to 932 amps?
Arrrrrg!
