My resulting numbers seem way off...
...I have a 310 watt 24 volt solar panel, 60 Amp MPPT charge controller hooked to a 100 AH AGM 12 volt deep cycle battery. A 1100 watt inverter is connected to the battery.
Just for a experiment, I want to plug in a 600 watt hot plate. How long will the battery run the hot plate until battery is 50% discharged??
Here is my numbers: 600W divided by 120 volts = 5 Amps. 100 AH battery divided 5 Amps = 20 hours run time. 20 hours times 50% equals 10 hours of running That just don't sound right, what am I missing?
PS, I understand that I will have energy loss due to heat, resistance, voltage drop over my lines, etc. I'm ignoring them for the moment(not that significant, i think).
What numbers do you come up with?
