Trying to work out how to calculate efficiency of my system.
Specifically I'm trying to work out what dbus path to use in order to take into account the self-consumption of the inverter.
/system/0/Dc/Vebus/Power
It does not appear from some testing that this takes into account the self-consumption. It appears to be equal to the power used on the DC side in order to provide the output AC power.
I could always take all DC side counts from the battery power, PV power, and the same from the AC side, and work out the difference, but was wondering if there is any dbus path that could be used to identify the self-consumption of the inverter?
ie path1 = DC power in for inverter total power needs, path2 = AC power out from inverter.
I would also be interested in doing the reverse, for working out efficiency of the charging function.
