Troubles with my Solis inverter

[heindlalexander]

Hi,

to be honest, this is no question regarding this integration, but I know, many people here are technically focused and I would like to compare some values here, as I'm facing troubles with my inverter.

It's about an S6-EH3P30K, which drives me crazy with it's external fans. (I'm already in contact with support, but so far no solution found - latest firmware is installed). The fans react very "nervous" when the inverter is at about 1000W. The root cause (in my opinion) are the fluctuating current values of the 3 phases measured by the inverter. Not the meter, but what the inverter "produces": A/B/C current. "Active power" then is the sum of these values multiplied by the voltage. The Eastron Meter itself seems fine, I see no such spikes there.
As the external fans are driven only by the power of the inverter, it's starting/stopping/fast/slow) all the time, when active power is at about ~1000W

So, my question is: Can somebody post here a similar graph, so that I can prove my suspect?

Hi,

hope this helps, Solis S6-EH315K-H:

Thank you very much! It seems to prove my suspect. If you agree, I‘d like to use your screenshot for Solis support. OK for you?

yes you can use it and if you need other screenshots with more power draw or something, I can create these also

Thanks, I really appreciate that! Maybe just one question: What is your experience with the fans? Do they start and stop very often? Maybe a sudden start to high speed? Or only changes between off and slow mode? (Except for high power from solar or similar of course)

haven't noticed that it would be annoying, server rack standing 4 meters further makes more noise, so Inverter is silent compared to it.

Thank you!
