I have brand new installed Solar 8.8KW + 2PWs. Pre PTO, self powered mode.
Apparently there is issue in installation and customer support gave me message, that system is self configuring (who knows ?!)
But here is the fact:
At this moment Solar Production:
car charging
That's quite not possible! House has some base consumption like 700w. Car is charging 16@240=3.6KW, But App reporting house consumption is half from that, Just 1.8KW !
Yesterday 8/30, I had self powered case 98%+, but my provider SCE reports, that I consumed from grid each hours. Which completely opposite to what
Powerwall reports 8/30:
South California Edison, hourly consumption from grid
Seems like PW track 50% of actual house load.
Additional facts:
- Car charger and AC are NOT backed up by power wall.
- Increase / Decrease amperage of car charge - proportionally ( from actual 50%) increase /decrease House usage on PW stats.
I fell my installation has an issue in wiring.... and self powered mode is not self powered mode now.
Thoughts ?
