Why does the AC500 sometimes take some power from grid even when Charge From Grid is turned off?
Hi @digait, Could you please confirm if the serial number of your AC500 is AC5002308000976556?
We have already pushed the new IOT firmware version v9041.10 for you, and we hope it will help.
Yes, my serial number - and latest IOT installed.
Sorry, but the inverter shows the same behaviour:
from time to time it loads a bit from the grid.
I noticed a few days ago mine too will momentarily draw Grid power when I turn on a heavy load, like my Microwave. It lasts maybe 5 seconds then goes back to Zero. Is this some kind of power use surge protection?
Interesting to know if there is such “power use surge protection”
because I also have some heavy consumers (about 2200 Watt)
and now I have plugged the AC cable from the grid.
Hi @digait, We believe this issue might be related to your UPS settings. Could you show us the interface you have set up?
Additionally, is it possible that the solar charging is not performing well, resulting in occasional loss of input and switching to grid charging?
