Hi, I tried ti find an answer to my problem reading 9 pages + grid failure filters but do not see wothming to help me.
My system is Multiplus 3000 + MPPT 150/45 + LG Resu 3.3 + CCGX + ESS . All software/firmware updated.
When there is a grid failure and IF my multiplus Inverter is running, I see the multiplus commutating immediatly to battery+solar mode to power on Ac out... Nice and no power vut in my house.
But if the grid failure comes when the Inverter is not running (pass-thru mode) AND the battery SOC is > to SOC min (even if SOC is min, I read that the SOC min is not follow for grid failure, correct ?), I get no more power on AC out , I mean the Multiplus is not running inverter and taking power from battery, even if I wait for several minutes... Should it no commute very fast to back up mode ?
Where is the problem ? Is there a Grid mode setting problem ? I'm in France and cannot use the French Grid mode because the multiplus has no internal ENS (VE config refuses this mode), so I tried with UK & German grid mode with LOM B, but same result = I turn OFF the grid on evening (no more solar) and no power goes from battery to my house...
Should I select the GRID "OTHER" mode ?
Many thanks for help or suggestions.
