Does anymore know of an ESS mode or way of configuring the Cerbo GX / Inverter so that feed-in via the AC IN is disabled, but loads on the AC OUT are still powered by the battery/DC supply?
I've tried disabling feed-in, but that disables the inverter outputting to both AC IN and AC OUT. I just want to disable output to AC IN.
Putting the MultiPlus in to Inverter Only mode kind of does what I want, but it restricts the AC OUT to DC supply only. You can't use AC IN to pass through to AC OUT.
Maybe it's not possible due to the way the inverter works when it's configured for ESS?
