I drove yesterday and today to work and home. That are 4 runs.
4 times 40 minutes.
Both days where dark and in need of wipers and heater.
So almost worst case scenario.

When i came home, i derectly measured voltage at the poles of the batterybank.
11,6V.

So what does this mean?

Lets use this chart. I have an AGM deep cycle.



This chart says there is around 25% left.
But batteryvoltages raise a little bit more when you let it rest an hour or 2.

It is safe to assume there is somewhere around 30 to 35% left.

Using my previus calculations, the Wattmeter should show an energy use of?
30%= 105Ah (x 12V) = 1260Wh/0,855 = 1475Wh


The Wattmeter should show an 1,4 to 1,5kWh.
In a few hours (3 to 4h) i post the proof!
