Hi. I have a VW T5 with a 12v leisure battery connected to vehicle battery via a 140A Sensitive Relay (Portable Power Technology).
I have fitted a 150W solar panel and SmartSolar controller MPPT 75/15 to the leisure battery. My problem is that the split charge relay constantly clicks and only stops when I use power from the leisure battery (turn lights or fridge on).
Is this a problem with the controller settings or the relay?
