My MPPT 100/30 bluetooth load fails at 20% on my android units (phone and tablet) and son's Apple phone.
When I follow the recovery directions it asks for a PUK Code. There was no reference to a PUK Code on anything in the box that I got from the installer with manual etc.
The box has a label with an SN: and a PN: xxxxxxx. Are these the Serial Number and PUK Number?
I can't easily get to the back of the unit.
