You can set it using ve config on the inverter tab. Check shutdown on low SOC and set your percentage there. You will need to enable battery monitor on the general tab first.

Thanks for you answer.

I activated the battery monitor at the general tap and entered the capacity.

At the inverter tap i can only find

DC imput loq shutdown 37.20volt

Dc imput low restart 43.6volt

Dc imput low pre alarm 43.6volt


Im searching for the settings at % of battery depth of discharge.

I thought that when you use the ESS assistant it ignores the inverter tab shutdown values.

It is not recommended to use ESS in an offgrid setup.

@Melonentier you may need to update ve config then, this is the version i am running.

When i open ve config and open a new remote file with full options i can edit the settings for soc restart. At the top there is written quattro.

But when i open the file i download from my inverter multiplus im not able to edit the setting. Is there anything where i can switch to full options?

@Melonentier

Again I have no idea. Maybe switch tactics - try Victron Connect for local programming. I see the option there as well, I am using the demo library.

Are you using VRM or and MK3?

@Melonentier

Another thought here is the firmware on your inverter up to the latest release?

I updated the firmare of the multiplus via mk3 and victronconnect to 470. After this the setting popped up to edit. The update resets all the settings make sure to save it first.

Thanks fpr your help!
