Victron EV Charger in standalone with Cerbo GX and ET340

Q&A and troubleshooting EVCS

Good day All,

We received a request for a Victron EV Charger. Please note that this Unit is standalone. We installed it with a Victron Cerbo GX and ET340. For some reason the EV keeps showing LOW SOC when plugging in the vehicle. We’ve tried to change the the register 5068 to one as shown in this link below, but the register returns to 0 when I change it to 1.

We’ve done a few with a full hybrid victron system which was quite straightforward but having the EV charger as standalone seems to be quite challenging.

Am I missing something ? Any advise would be greatly appreciated.

Hi, update the EVCS to the latest firmware and in the settings, there is one called “virtual battery”. Enable it and that should be it.

Hi Lucian, thanks for your feedback. We’ll go back and I’ll update you if we succeeded.
Thanks

What would you want to achieve with the Cerbo and the ET340 ?

I presume you want loadbalancing but that is not a feature provided (yet). What is provided is overload protection. It should work without adjusting registers now as there is a function called “Backup battery emulation:” in software V.2.00.

The post you are referring to is of 2023 which is a long while back.
