load is calculated incorrectly and invert_grid problem

seebaer1976 commented 1 year ago

Is there an existing issue for this?

Current Behavior

The calculation of load is incorrect, the inverter power and the feed into the grid are added together instead of deducted. And when purchasing from the grid, the value is deducted instead of added to it.

Feeding into the grid is a positive number, drawing from the grid is a negative number.

power

and with the mains and battery I can't get the power values and the animation to match. If the values are correct, the point is wrong, the point is correct, the values are not correct.

I tried everything with invert_grid, invert_power and show_absolute, but nothing gave the right result.

maybe there is a solution

Hi. The formula to calculate essential power (load) is for the single phase inverter and based on the Sunsynk registers. (essential = inverter_power_175 + grid_power_169 - aux_power_166). Since you are using a 3 phase setup and a different inverter (possibly different measurement points) you should rather provide your own load sensor in the card config. You can add the following entity:

essential_power: <your sensor here>

The card defaults for grid power is a positive number for grid import and a negative number for grid export. If your sensor is inverted then you should set the invert_grid: true.

problem solved I simply put on the appropriate sensors. It's a bit more complicated, but it works
