Why isn't my DC power direct ?

Hello,

I have a Quattro 10 000 connected to a Cerbo GX. My quattro is in manual mode, so i can decide if it is charging or discharging my battery. When i ask to charge 1000W, the input AC power follows the request but my DC power don't really follow it...

I don't understand why my DC power si so different from my AC power... Is it the result of the instability of the grid ? Because i'm conneced on a singlephase '' micro-grid '' which is generated by another inverter...

I see the peaks match at times,

My guess would be that the capacitors are charged when the AC is in the high area of the sine wave and then discharged as needed for the DC side of things component wise when charging DC batteries. sometimes this may cover a few different cycles.

This would be my thoughts but others may know more
