I have a simple setup in awaiting of the solar panels and charger - just the quattron 10000, 16kw of victron gel batteries with lynx shunt and cerbogx and NO other DC circuit. Meanwhile I use it as a UPS but also loaded ESS to try and learn the various options. The problem is 2-3 days after ESS was activated, the quattro starts randomly to invert. It blinks the led, I hear the buzzings and all, I can also confirm it with the smart meter and VRM graphs.
I even flushed the new firmwares 2 days ago, seemed stable when fresh but now it is again erratic.
It is set as keep batteries charged and always does this... it feeds-in without reason, and from the batteries!
The only way to make it stop (inspired by other threads here) is to set ESS to optimezed with BatteryLIfe , min SoC 100% and limit invert power set to 0, but then although quattro says Float, batteries slowly drain because of cerbogx.
What am I doing wrong? For me this seems completely illogical and unacceptable. And the thing in the graph below is just a huge one, because just looking at console the battery is always charging 1kw, discharging and so on. It never settles properly.
I can confirm it is a ESS problem only (at least in the current simple basic setup with no solar yet - but even with solar, will it do the same at night?), as without it it works as a stadard UPS should.
