If I compare the Live data of two systems, the last two rows of the comparison are the difference of Power and Energy in percent. But I don’t understand how this two values are calculated?
What ever I try to calculate, I get differnt values.
Look at the image, the yello marked row at 19:40h:
1st System Power = 692W, 2nd System Power = 200W, calculated difference = 37.5% less ?
1st System Energy = 39,517kWh, 2nd Sysetm Energy = 43.700kWh, calculated difference = 2.6% less ?
How do they get this percentage values?
