Inverter does not work (high dc-ripple, low battery warning)

For a few days my inverter is not working anymore.
There are no lights on, although it is closed.
The VRM portal shows that it is off.
When the generator is started, the batteries are charged and the charging light goes on. Batteries 100% full. The loading is displayed in the VRM portal.
If you turn off the generator, the inverter goes out again.

230v are only available when the generator is on.

Hi @torsten.b

Did you check your battery / DC wiring / fuses?
I think your battery is disconnected or broken, as a low battery warning -and- high DC-ripple warning are indicators of that.

Hi @tabney0315

The same answer for your system:

Try disconnecting shore power and see what your battery does.

I'll double check the batteries but I doubt it. They have been fine and are less than 2 years old and have been well maintained. It occurred during high load and power assist.

I disconnected from shore power and here is what the battery did. I have a 12v system utilizing 4 - 6v 220AH Lifeline AGMs wired in series / parallel


Also, here was my state of my system when the High DC Ripple. I had a second one occurred today.


Any thoughts?
