I bought 350W XLD Brainpower controller (Model 866C-6) with S866 LCD screen. I have wired everything, and it works as expected - however, after a while of use or when giving full power for a brief time, the power cuts off and the controller "shuts off". You can see the voltage from the screen drop from 38V to 20V and below until the screen goes blank.
After a minute or so, the controller can again be turned back on, and everything works again - battery voltage 38V. There are no error codes shown, or possibly E 10, but I am not sure if it's relevant to this. The controller is also not even warm to the touch, but the behaviour seems like some kind of failsafe trigger.
