Would love some help on an LB problem

Had LPG fitted a few weeks back, since then the LB won't hold charge and I get all the radio settings lost each time I turn the van off, heater setting lost, nothing works on the LB now and I can't see how they have managed to do that.
Taking it back to fitters ...

I am bout to put a semflexi panel on my unconverted AFT

can any of you give me an idea of where a good position for the mppt controller would be in the van please, still looking for inspiration on this

many thanks
Ben
