I'm trying to retrieve the yield of the PV panels connected to my SUN2000-3KTL-L1 with a LUNA2000 5kWh battery unit attached via Modbus TCP.


I've been logging the daily yield (register 32114) and accumulated yield (register 32106), and have noticed that the inverter doesn't increase this field with the energy used to charge in the LUNA2000 battery, but does increase it when it discharges the battery.


It seems to be impossible to accurately get the output from the PV panels by combining daily/accumulated yield and storage total charge (register 37780) and storage total discharge (register 37782) fields, as this produces incorrect values (DC to AC conversion losses?)


Is it possible to make available the energy produced by the PV panels, and the energy retrieved from the battery separately? On the FusionSolar website I'm able to retrieve the yield from the MPPT strings separately, but this information is not available via Modbus?

SUN2000
