System is with 10kWh batteries and probaly due to failure of 1 battery the system shut down completely. ( low batt. voltage)
The multi-RS will not start up at all ( completely dead) anymore after battery repair. Display is black. Remote on/off jumper is present.
There is grid AC and battery power (50V) available on terminals.
Anybody has any idea?
thanks,
Chris
SOC dropped suddenly to 0%. Voltage read 2.9 volt! Ater disconnecting 1 battery, voltage reading was 51V again. Probably something wrong with BMS in the batteries. Separate batteries measured all 12.9 V.(?!) but when connected in series, it dropped to 2.9V. But why couldn‘t I not start he Multi RS?

Disconnect solar, battery and AC Out.
Connect only AC in.
It should start from the power switch and the display should light-up with information.
If not, I believe it's defective.
But the system should get power from some source for the electronics. I think that should be the battery power.
As you've had an event on the battery side, then maybe it will be wise to check if it works powering it only by the AC In.
Believe me, when I've purchased my Multi RS, this is how I've checked its functioning, by powering it only by AC In. It should start, the display should work and also the bluetooth connection with VictronConnect should work.

Still no result, tomorrow I have appointment with Victron Service Center.
But thanks anyway for respons.
Alex,
I visited the Victron service center and they connected the RS on a 51V power supply. No problem. Probally my batteries created the problem.
I aquired new Pylontech batteries, together with Cerbo GX and a special Ve-can cable and everything works great.
