Energy helper kWh jumping up every morning

[lime horizon]

I made a solar helper based on my inverter's input watts vs output (1000w out - 700w in from the wall = 300w of solar power) that turns off at night (when the sun is below the horizon) due to the fact that the simple math I use doesn't account for the fact that my inverter has something called "AC load assist" where it limits incoming AC amps and draws current from the battery to help power loads if the loads get too high. They both look exactly the same so it looked liked I was producing solar at night when I wasn't.

when the binary sensor outputs off, the code outputs 0w

that power helper sensor feeds into this integral energy helper

Use left riemann.

the problem I'm having is when the sun outputs ON in the morning, this happens

The jump is from Trapezoidal rule.

what's the difference?

interesting

Thanks

What solar integration do you use that you don´t have an energy sensor?

[lime horizon]

I don't. I calculate solar by subtracting the inverter input watts from the inverter output watts. I have no sensor that measures solar outside of that difference. I had to solve the night problem because with the AC load at night (it's on a 20A outlet derated to 16A continuous) I can't power the loads fully with just the outlet
