Total Solar production = 10562w
AC Loads 11021w
Battery idle (fully charged)
Grid in-feed 3685w (feeding in to grid)
Not sure how AC loads and grid in-feed can exceed total Solar watts when the battery is idle.
Why does the math not add up?
Thanks

Cerbo data displays bad math
How are you metering everything?
Is it all AC PV or a combination with DC?
Sometimes it is a meter issue.
All metered via VM-3P75CT, one on output from SMA PV inverter to AC grid second meter monitors grid input.
Hardware list is;
1 x MPPT 450/200
3 X MULTIPLUS 2 48/8000/110-100
2 X VM-3P75CT
1 X CERBO GX
1 X BYD BMS + 30Kw battery bank.
Tried to upload a screen shot buy failed to parse.
You should add the information which of the values seems to be "accurate", and which is the one that seems to be unrealistic.
Without any more details, hard to guess, but I have a strong feeling that your second meter in front of the SMA is not operating as expected. Maybe it's configured as a load-meter instead of a Solar-Production meter in cerbo?
Any idea how to upload a screen shot, everytime I try I get an error, alos tried uploading as a file but again get an error. The screen shot would show things alot better than text
Is it possible that the Cerbo is adding the grid injection to the AC load total? It is kind of an AC load to the system.
