I have an AC500 with 2 AC300S batteries. The unit turns on just fine but I have no touch screen on. I can turn the AC or DC on via my cellphone Bluetti app no problem.
Is there a 15 or 20 or 30 amp small fuse that is keeping this off.
I have checked all the battery connectors and click in fine.
If there is a small fuse that needs to be replaced where is it? Thanks for your help
I had a third battery and AC300 but I took it off to use with my AC300 unit. The trouble started after I disconnected the battery
