How I calculated the power requirements to run my household 240 volt well pump in a power outage.

10A at 240V = 2,400 watts continuous. I will need an inverter with at least twice that (4,800) watt surge power for the initial startup.
However, as the well pump only runs for 30 seconds at a time, and my water usage is minimal, I only need about 1KWh of energy storage to run the well pump for several days.
The next few videos will talk about selecting the inverter and batteries for the system.
