I just connected my 1kW Navitron turbine up and connected the 4 new "12" Volt batteries I bought from a local ships chandlers.

They are Fiamm deepcycle type 685.

With the 4 connected in series to give a nominal 48V, the actual voltage across then is currently 62.8V which is too much for my inverter which trips out.

One battery measures 14.2V, the other three are 16.2V (+/- 100mV)

Are the batteries duff? The little indicators on them say they "require charging" 16V seems too high to me...

Tim.

Tim, are you measuring the voltage when they are connected to the charge controller and the turbine in good wind, if so then the voltage (62.8V) would be as expected as the voltage on a live system has to be higher than the 48V or your batteries would not charge.
Perhaps I am reading this wrong, but I think you have good batteries and everything is working as it should
