Hello,
I have recently (within the past several days) been encountering a new issue with the AC200L.
I live in a location where power may unexpectedly go out or be turned off per a schedule. Therefore, the AC200L is almost always connected to the power grid.
In any case, in recent days, the AC200L has begun to switch off when I have two or three of any of the following appliances on at the same time: microwave, toaster, water heater, small oil-filled radiator. The AC200L shows an error message related to inverter overload. This takes place when there is electricity coming in from the grid without interruption.
I should say that in the nearly two years of using the AC200L until this point I had not faced this issue. Thus, if there was a limit on pass-through for the AC200L as a UPS, I theoretically should have run into it a long time ago. This leaves me stumped.
The AC200L is running in standard UPS mode. The charging mode is also standard.
As I have experienced some periods of power grid instability, the grid self-adaptation feature is enabled. It has been enabled for half a year.
Thanks for any advice that you may have about this issue.
