Passthru but still inverting in case of grid failure?

so where i live 1-3pm we have cheap power, but i dont need to charge my batts during this time, instead wish to do passthru, so currently im setting inverter power to 0W during this time, however im thinking in case of grid failure the power will fail because inverter is set to 0W during this time?

so whats the proper way to do passthru without charging or discharging batts, but while still keep failover possible? my 2nd idea is at 1pm just get the current battery SoC% and set minimum SOC % in ESS from 1-3pm, hows that? seems to work

or someone have a better idea?

i can run dbus commands no problem via ssh on cerbo and make my own scripts

here’s the command i run to set 0W inverting:

/usr/bin/dbus -y com.victronenergy.settings /Settings/CGwacs/MaxDischargePower SetValue 0

and to re-enable inverting:

/usr/bin/dbus -y com.victronenergy.settings /Settings/CGwacs/MaxDischargePower SetValue – -1

Just give it a try. :slight_smile:

It should switch to inverter mode and supply your loads.

You can try this node red flow. It will send a 0 between 1 and 3pm. A 5000 outside the hours and also check AC in and if its not there send a 5000.
