Multiplus Temperatur Failor

Hello,

i got a problem with my multiplus 48/5000.

It worked fine for one week.

it got a lithium battery 48V 200ah, a cebro, and the net connected.


Since Yesterday its showing *Temperatur alert* all time, it never warm, its not working, but fan is working like cracy.

The Multiplus is completle cold.

Their is no tempeatur sensor attached. Also attaching one dont change the problem. Restarting dont solve the problem.

Thenever i start him, he shows temperatur allert and dont work.

Any ideas ?

@gamechanger battery voltage of 49.9v does not equate to 72% soc for a Li battery.

What battery and BMS do you have?

Multiplus dont change even if i dissconnect the multiplus from cebro, so he cant have any information about the battery.
