AC2000L pulls from grid randomly

So I have my AC200L setup on PV priority and plugged into the wall so that my loads will remain powered if the battery is depleted. Ive noticed that occasionally while running various loads (from 100 or more watts) there is a blip of grid power that is displayed on the screen. Ive mostly noticed this when the fridge or small window AC unit starts up. Most of the time it’s between 50 and 500w but just for a brief second. I have a kilo-watt meter hooked up to the grid connection to monitor the amount of grid power I have been using. in the past 7 days my batteries have never dropped SOC to the 10% threshold I have them set to but I have used approximately 1.5KW/H from grid.

Has anyone noticed this or have any suggestions? @BLUETTI_CARE any ideas?

I’m not really concerned about it but more curious as to why.

Thanks in advance, MJ

@MJ650rzr Please provide me with the SN and the firmware version of your AC200L and I can check if there is a new firmware.



@MJ650rzr I’m sorry the firmware is the latest one. The input will automatically match the load, so this situation will occur when the load power changes.
