So the end of the month and today on the house we made 17.10Kwh no hot water but battery at 100% and zero export
The workshop made 6kwh today battery is full and zero export
And for the month the House total for the Month of 709Kwh target for the house was 765Kwh so we are low on that the workshop made a little over 250Kwh total
and I'm happy with that

House System is split East West
down in not so sunny Devon.
East 8 x 420w panels 45 deg pitch
West 10 x 420w panels 45 deg pitch
Givenergy Gen3 5kwh hybrid
2 x 9.5 battery's

Workshop system is South/East
2440w of panels two 720w strings
one 1000w string
Hybrid inverter with 4x 12v 100Amp
Battery's
Plus grid tie inverter as well

That seems odd, estimate for August is 419 but Givenergy Portal is telling me 551, will have to wait to see what solax reports, guess it needs a while to add August to the graph for yearly view.

Edit
Added them all up manually, Solax reports 581.4 so 551 tracks after losses from panels > string inverter > AIO Inverter.

My 5kw system in August - 580 generated.
639 exported= £151
354 imported= £71
With SC about £65 profit.

Not a single 30+ day I don't think, the lack of sunny evenings pushed down the export in the premium window a fair bit compared with July and June.

I don't know how given it has been solidly grey all day and rained a bit this afternoon but:

17kWh generated, 7.5kWh exported.

25kWh was forecast, fat chance of that here today!
