Hello,
I operate a Victron ESS system and every now and then a strange phenomenon occurs.
On the Multiplus 2, the Main On and Balk lamps light up continuously and the Inverter On flashes.
The Multiplus are always short. The fans run louder at full throttle and then a little again. As can be heard in the video.
I couldn’t really find anything unusual in the VRM portal. No high performance or frequent load changes.
Does anyone have any idea what the problem could be?
Thank you
Thanks for your answer.
But the system is configured as ESS. How can the power assist be active?
Why should PowerAssist cause such a behavior?
I agree that the system is power assisting, but the fan noise is certainly interesting.
So no related loads - what is the base load though at this time? It is the same as other times?
Is the system charging at all or feeding back to grid?
I couldn’t find this code in the app.
Here are some pictures from the VRM The video was recorded at 19:03.Everything looks good to me so far, or what else would be interesting to look at?
At this time of day, however, there was no longer any power coming from the MPPTs.
What firmware are you on?
Do you have the fan modification on these units?
The v552 is installed on the MP2 and only the ESS assistant is running.
