Could you please assist an end-user with limited knowledge:-
The system we installed in our new-build is 7.83 Kw of PV with a 'Solax X3' 3 Phase inverter. A later addition was a Tesla Powerwall 2 with the later gateway. Following a series of short (2min) power cuts and lights flickering UKPN monitored incoming voltage for a week. Result was fluctuation between 202v and 257v - they are now checking sub-stations. Not sure if that is relevant but mention it in case.
Problem - UKPN engineer noted reverse current on our new 'Secure Sprint 211 Smets 1' 3-phase meter. I understand that this must relate to the PV array in some way. Electrician has identified an imbalance across the 3 phases, typical figs are - AC Power 1 =130w, 2 = 137w and 3 = 152w this morning and AC Power 1 = 1913w, 2 = 2065w and 3 = 2070w this afternoon. There are no error codes showing on the display or web portal.
It is now 2027hrs and the meter is still flashing on L1 indicating reverse current (as per installer's manual)
Two questions please - Is the imbalance a problem and, if this is the cause of the reverse current, why is it still flashing at night?
Any assistance you can give would be appreciated - Solax Tech Support is simply an answer phone shut in a cupboard with no response.
Thanks
Pete
