This is happening over the last 2 days...
As my battery gets to 100% the Solar is apparently all going on house load -- or so the graphs say. This isn't the case (my emporia system says it is being exported). But the graphic on the Portal and in the web app is showing the excess solar as being consumed in the house, not exported.
Anyone else seeing this?
Emporia view is currently 3kW being exported...
My system is now discharging the battery at a reduced rate (300W) even with all this solar and this is true according to the Emporia monitor. Solar showing at 4300W. House showing as 4500W. Grid is showing as 0.
Max charge and max discharge still work. It is ECO mode that has stopped working.
I think I've lost the Grid sensor input and the app/portal calculation puts all the excess solar down as house load.
What to do first...

Yes, that was my first thought. On my system, CT clamp goes into a small meter (EM115, or something like that), and then the inverter can interrogate that through a serial interface. That cycles through various numbers, and you should be able to power-cycle just that little meter.
DD Thanks. That was going to be my third action. First action was to restart the inverter. Second was to power down the inverter and batteries and power them back up again. Fourth would have been to fiddle with the connections (always worth doing the power cycles before jiggering it up any further).
The system came back to life after the first action! Looks like the inverter had a brain f..t.
Keeping a close eye on it now.
Restart was at 4.35pm
During my inverter (AC3.0) outage yesterday the app and portal stored no energy data. Polling the inverter continued to work and the power graphs are OK - just the energy graphs have gaps.
I know there are 2 CPU's in the inverter (and another in the Dongle). Perhaps just the ARM or the DSP had crashed? I suspect the ARM does the network side whilst the DSP does the calculations which might explain the 0 grid reading and missing energy entries as the DSP had crashed?
I wonder if this is the root cause of missing data people see occasionally?
It messes my stats up and may be why my GE counters always report between 2 and 5% under the smart meter counters.
