Cerbo and SmartShunt drain the battery close to 0%.. what to do?

[Frisianstar]

The Cerbo and the smartshunt drain the battery close 0%, this morning it was already 3%.. 2 days ago it was still close to 10%.

The Multi Rs 6000 switches off the battery use for ESS when battery soc falls below 10% soc.

Only surplus pv power will charge the battery, and is often not available in December (ESS setting).

I can’t switch of the cerbo because it has to remain in standby mode.

What can I do?

There is not much you can do, you need to charge the battery or switch off the system.
