A 32 volt 1940s vintage Jacobs generator will work fine charging a 48 volt battery. It will produce the same maximum amperage at the 60 volts to fully charge a 48 volt battery as it produces at 40+ volts to charg a 32 vollt battery. Among us Jacobs users, it is very common to use a 32 volt Jacobs to charge a 48 volt battery and they work well, if the battery and load is large enough, without any electronic generator regulation. All I use is a hefty diode (rated at100 amps or more at 200 piv or greater, depending on what is available at a good price) as an anti-motoring diode, and a fuse. The stock original cabinet of relays isn't necessary. The wind turbine will work fine, and will produce the maximum amps (70A for the 2.8Kw machine) at the higher voltage and therefore more watts, in a slightly higher windspeed than in its original configuration. We've been using our Jacobs 2500 watt machine since 1977.Make sure your tower is properly and adequately grounded--nearby lightning strikes sometimes blow out my anti-motoring diode even with good grounding of the tower.No DC-to-DC converters or other fancy stuff needed. Jim Erdman, in Menomonie, WI QUESTION ON A PROPOSED 32/48 VOLT DC?MIX:
Since I just monitor the EVDL, I have not learned the correct procedures to post. I hope that jumping in here with a question will be acceptable. Question: Will a vintage 2800 watt, 32 Volt Jacobs wind generator charge an L16 FLA, Interstate 48 Volt battery? The Proposed System: A 48 Volt DC to 120/240 AC ?Out Back inverter would be fed by a ?4000 or 8000 Watt PV panel. My question then, is it feasible to add the 32 volt wind plant to charge the battery on a cloudy day? -------------- next part -------------- An HTML attachment was scrubbed...
