Hi All,
i apologize in advance if i'm posting in the wrong place, and please do point me to the correct one
Total noob here. A recent typhoon got me thinking about making an offgrid backup for my home. Nothing too big, just enough to run the lights and a few appliances.
That said, it seems like a waste to have an offgrid system just sitting there, waiting for disaster to strike(thankfully quite rare in our case), so i had the bright(?) idea of hooking up the water pump to it. So basically what should happen is
Normal days: offgrid kit powers AC water pump
Power gets cut off: lay down extension cords to power some lights, gadgets, fans, small appliances
So here's what i have in mind:
Bill of materials:
100-watt mono solar panel, output = ~17.6V max, 5.71A max
100Ah LiFePo4 battery
MPPT charge controller, max 20A
Inverter, 2000W max
Water pump, 220V AC, P1 = 1100W, P2 750W(amps estimated at 5-6A)
The pump is hooked up to a water tank, and only engages when near empty. My rough guess is that the pump engages only around 2-3 hours daily as the tank water level drops.
You think this will work? tia
