I have 9 solar cells each one is 15 watts at 17.5 VDC. These are designed for charging a car battery.
I have them connected in parallel and connected to a car battery. I have a 300 watt DC to AC inverter connected to the battery. I also have a 400 watt inverter and a 1000 watt inverter I can use if I need to.
I can do a lot with 300 watts or 400 watts, lights, soldering gun, etc. I could use a way to know if I am pulling power out of the battery too fast or too slow so I can pace my electrical use so the battery will last all day.
Is there any easy way to know how much power is going IN or coming OUT of a car battery?
