A pal of mine bought a boat in Holland fitted with a Liemo Zephyr 3000 Combined Inverter Charger but we are having problems with it and cannot find any information about the beast. I have tried phoning Liemo but they where very vague (I think the company may have changed hands) and could only suggest I "play" with Dip switches 5+6 on the circuit board

The main problem is that it is overcharging the Batterys and not switching to float charge until the Voltage hits over 30 Volts

I have already tried running the unit via a Variac to bring the supply down to 230v and that seemed to help a bit but the batterys are still overcharging.

Kind regards, Andy
