My inverters are taking all the power from the grid even when the sun is shining and the batteries are fully charged. The inverters are in charger mode and will not switch to inverter mode. The inverters are in external control mode. If I disconnect the grid the inverters work without any problems as an island system. All devices are updated to the latest firmware.
I found a topic on this forum with the same problem, which was solved by reinstalling cerba GX. I tried reinstalling my Ekrano GX with the latest and older firmware, but nothing helped.
I have installed and configured ESS assistants in all Multiplus II, in Ekrano GX I have it set to Optimized without battery life and allowed to feed into the grid
Solved. External gridmeter is not necessary, it works with integrated meter. The error was in the grid code setting “Use AUX1 as disable FeedIn signal”. After disabling this function everything works.
