Inclusion of battery means current power output is not correctly reflected #34
Description
Based on my observations when a battery is installed as part of the SolarEdge system the plugin does not correctly reflect the current power output.
It appears that the power used charging the battery is treated as part of the 'closed' SolarEdge system so the Overview API gives a lower than expected reading of the current power output. It's the sum of the GRID and LOAD values rather than the current PV power output which I think is the intended display.
If there's no battery installed then the Overview API will give the same value as the PV output.
I've reached out to SolarEdge support to confirm this is the intended operation of the API as the documentation isn't clear.
If so will make submit a PR to modify to use Site Power Flow to report the PV output
