Good morning,
if I add a Solaredge battery (DC, directly connected to the Solaredge inverter) to my PV.Sol-project, the produced energy goes down from 8.1 kW to 7.6 kW. I traced that down to the DC/AC-conversion (german DC/AC-Wandlung), which has a loss of 266 kWh without battery and a loss of 665 kWh with the battery.
I do not understand this. The difference between loading the DC-battery and unloading it is just 88 kWh - this I can understand.
Why should there be much higher losses in the DC/AC-conversion, if a DC-battery is added?
Exact inverter and battery used: StoreEdge SExK-RWS + 1 x Home Batterie BAT-05K48 (4.6 kWh)
