Hey.
My gear is Quattro-II 48/5000/70-2x50 with Cerbo GX and Dyness LiFePo4 batteries.
Everything is up-to-date:
Expected behavior: power assist only kicks in when AC current limit is reached.
Example:
- AC current limit is set to 10A;
- AC voltage is 230V;
- As long as power consumption is below 2300W power assist never kicks in.
Yes, I understand that some power consumption peaks might be significantly higher than average power consumption figures.
Actual behavior (wrong): power assist kicks in constantly while consumption is not even near the AC input current limit.
Example:
- I have some load which on paper can consume up to 2000W in total which it never does according to 3 different power meters that I tried (including Quattro-II itself);
- According to VRM the AC input power never exceeded 700W;
- According to VRM the AC output power never exceeded 900W;
- According to VRM the AC input current never exceeded 8.5A;
- According to VRM the AC input voltage never dropped below 206V (at that moment the current was 7.8A).
And here’s the problem:
Power assist keeps kicking in constantly when I set AC input current limit to 10A, 13A, 16A, 25A and even 32A!
When I set AC input current limit to an insane 63 Amps it finally stops doing that!
Also I’ve managed to take this screenshot:
It makes no sense!
214.3V at 7.8A is 1671.54W, not 516W
But maybe it’s just current and voltage figures being shown out of sync.
