On the other hand, you could go dirt cheap and just utilize a voltage sensing circuit and a shunt. The batteries don't care what voltage is being generated while they are charging, UNTIL that is, they are fully charged, and then it is absolutely CRITICAL. So a simple answer is to just allow the batteries to charge with whatever is being generated, and then dump the power over to another load once they are fully charged. If you were generating wild AC, this could be done very simply by directing the excess power over to a water heater element to make hot water, which has various obvious uses. With DC, you'll have to use a specific dummy load. However, the entire circuit would likely cost under $20. I haven't seen any specific schematics for 48v, as most are for 12v or 24v, but it would be adaptable. Vince
