could be touching on some off the problems with trying to be too clever by not having a traditional alternator/charging setup.
Knowing that failure off the roof could give the car a bad name, best look after the electrics by monitoring alternator and battery charging.
And pass it off as some fancy eco thing.
Load shedding by limiting the function of non essential services could be the first indication of charging or battery problems.
Maniac, haven't you said elsewhere about slow roof operation?

Nah I don't have a slow roof, it can be a tad jerky at times when the weight shifts as it moves tho which could be battery or a million other things.
