I have a SR2 with a Hoffberg alternator directly coupled. Batteries are 6 x 8V to give me 48V. The genny is wired into my Pip (called Axpert in S.A.), but am having problems with earthing and when I try to feed the PIP, my DB trips, so it becomes a mission to charge batteries and power a load. My electrical skills are just not up to scratch, I guess. Sounds worse than it is, today is sunny and my batteries are fully charged now at almost 15:00. Batteries are not great either and don't hold charge as well as they should. I could be on 50V at sunset and down to 47V overnight with basically just a fridge running. Not the best fridge, but more efficient than most, the motor only draws about 80W. When I win the lottery I'll invest in a bigger, better setup, but till then, luckily the winters are not too long down here. (Plettenberg Bay, S.A.)
