Grid energy used yesterday 22/01/26 when battery was FULL and in Eco mode.
Grid power used between 0745am and 16:30pm then reverted to battery.
3 x L1 Voltage Fault reported by system, then reset by system.
Sorry the L1 Voltage errors were for 16-19-21/01/26 not day of fault.
Battery was completely FULL charged overnight.
What was the fault reported?
What was grid voltages etc.
L1 fault if you check the data at teh same time, the grid would have gone out of range for a split second perhaps, nothing logged in datapoints, but teh inverter did briefly react to it and in the data you can see it began a re-sync of grid
Its not a fault as such, more info.
Ill get this one masked out, it is likly just noise on teh grid.
A full outage would be logged as utility loss
Inverter is incredibally sensitive to grid disturbances, if this was one not mapped in its sinwave maps to handle, it would have dropped sync and the resyncronised again.
Ignore it
L1 Voltage FaultS ON 16-19-21/01/26 BUT NO FAULTS ON 22/01/26 when the inverter stopped providing battery power when batteries were full.
Grid Voltage was 246.4
Cant see any problems in Grid Voltage for that day between 242 and 245v
Problem was that the system remained in Grid Power for a long time over 10 hours before resetting on 22/01/2026 with no system fault or error.
Shouldnt resyncing be automatic not leving system full outage for most of the day.
Would be good to get some more detailed info on how a grid disturbance can bring my inverter and battery not delivering power for many (10) hours
Any way of automating an email or text from the system if the inverter and battery stop supplying power?
Currently you’d need to use something like Home Assistant to track and alert you when that happens.
I have now had 7 x L1 Voltage Faults reported, but Fault Message does not contain vital information on what actually is triggering these faults. They are becoming a daily event with randon timings. One of these caused a full battery outage for over 9 hours, with no associated system message, just an initial voltage fault.
When I look at the Grid data for these error timings:
Grid voltage this is relatively stable,
Grid frequency is more spikey but within specification.
Certainly well within Grid normal limits set at 49.5–50.5 Hz,
and emergency, short-term operation permitted between 47 Hz and 52 Hz

So what can be suddenly trigering these faults
