I have some problems transporting the hydro power into my batteries
Down the stream I have a water generator powered by a ford alternator. It is giving about 5 amps max. when connected to a 50 Watt car light bulb.
The alternator is connected to a 12 battery. To the battery is also connected a cheap 12->220 Volt inverter. (auto shut off when V<12 or V>16 volt).
The 220V form the inverter is going to my house, about 300m or 1000 feet up stream using a normal household cable (3 times 2,5mm²)
Near the solar system I convert the 220 Volt to a constant current of 1 amp, witch charge the 48 volt battery bank. (Current source with a 7805).
It's not much but its ok for about 1KW/day.
It's a very sensitive system and it has used more lives than a dead cat!!
It has used another live yesterday. The inverter isn't working anymore.
Does any wan have a nicer solution for the 12 to 48 Volt conversion with a long cable?
Of course it has to be cheap, or at least not very expensive or complicated.
