Input power = Power entering the inverter on the DC-side (=solar panels) Things get more confusing if your setup contains a battery. Power flowing to the battery will not appear in the Active Power, but power flowing from the battery is included in the input power. The efficiency calculation + Riemann sum tries to filter out the pure yield from the solar panels, excluding the batteries, but including the inverter DC-to-AC conversion losses. |

Hi, first of all thanks for this integration and the hard work. I'm very happy with it. For me it's working with a LAN connected inverter via Modbus TCP.
But after testing now for a while, I'm still confused about some of the senors. I've also read the wiki article about the daily solar yield.
What is the difference between the "inverter_active_power" and the "inverter_input_power"? While in the wiki it was recommended to use the "inverter_active_power" and then process it with the efficienty calculation and riemann sum, the "inverter_input_power" seems to be pretty much the same value as Huawei uses for the FusionSolar portal as "Input yield", so it seems to be good to work with that one, doesn't it?
Later a day, both sensors have the same value, but this morning, they were quite different. Thanks for any explanation on that. And in addition, does anyone know if the efficienty losses are already considered in the Huawei portal (or using "inverter_input_power" sensor)?
