This is following on from my problem with the inverter being in "sustain", voltages were set too high in the ESS Asistant for the batteries.
It's a very simple system, a MultiPlus-II 48/5000/70-50 with 3 Pylontech US2000C batteries and a analogue current transformer to monitor grid current.
Now the inverter has gone into "PassThru".
I hav checked the FAQ in "ESS Design and Install", 10.4, but all seems to be OK.
So this is showing I have both grid and battery monitoring.
Charge and discharge are not set to 0, zero.
Grid code set as appropriate.
When it was in sustain the charger would come on when it was bright enough until the Pylontech BMS said no more, but it doesn't do that any more so gradually losing charge.
Thanks for any help.
