Any idea how to investigate why mppt controller Smart Solar 100/20 was producing no output?
It was not in the morning with first sun light, it was around 2 PM.
There was plenty of light, MPPT showed it had +- 70 V on PV side (this is 48 V system)
Charge mode was bulk (set to 55.2V), battery had SoC 55 %, 51 V
yet current/power was zero
I've checked in alarms/errors, but did not see anything there
Checked with BMS, there was no error, charging was enabled
After +- 7 minutes I turned it off and on again and it started charging immediately
VRM portal missed this 7 minute interval, so nothing useful there
Any idea why it happened or how to debug it if it happens again?
