Good Morning All,

I'm having to do some 'guesstimation'.  The total figure from the three meters is 483.2kWh but the meter fitted to the PV Expansion bit also records the Growatt battery output.

I'm still trying to work out how to extract the information I want from ShineBus but the Immersun is telling me that 66.5kWh of this was what the Growatt put back into the system.

My year on year import of electrickery has now dropped to 7871kWh.

Regards

Richard
