AC50S not showing AC Watts being used

Hello, my AC50S will not show any power being used when I plug into the inverter. The inverter does work, powers up the devices I use, no indication on the panel. the DC side works fine. Any ideas would be great. I have tried for several months to get a hold of Bluetti support, by phone and email, no response.

Hi @wntrhwk , In the case of relatively low power consumption, the output value will not be displayed. But the machine is supplying power to your device normally, please don’t worry.

Hello, I was using a small drill that used over 60 watts. When I first bought the AC50S it would register the drill with the proper wattage showing on the panel. It would register down to very small wattage. Now it does not register wattage at all.
