MultiPlus-II 48/5000/70 is shutting down continuously with an overload error after some issues on the grid network.
Batteries are full and the external grid is off (as the mains circuit breaker failed). BlueSolar Charger MPPT 150/70 is connected and providing power (as the sun is up...)
Now the MultiPlus keeps trying to start up, but fails within a couple of seconds with an overload error. However, the circuit breaker towards the load is off as well, so there literally cannot be any load on the inverter at all.
Is this a bricked MultiPlus or is something else going on?
Tried a lot of stuff, including restarting the system through the Color Control GX as well as with the on/off button itself.
Anything else to try?
The system is installed in the south of France, and I'm asking for someone else, so troubleshooting is going to be a pain.
