The negative diode is wrong way around so will do nothing, if the other way around the alternator will short via top diode. /rebates/2fo2fbatteries-electrical-wiring&. I dont see how Bruce Harveys circuit can work.
#24 volt alternator charging system free#
Contemplating,reg-micro connected across the 24v to switch a NPN fast for the Alt / solar input - with Alt / solar feed connected pos and neg to free battery terminals - but that was a disaster. I tried a buck booster to 29v but found one battery would start taking most the charge. As people mentioned, you'll need about 28 volts at the output to charge 24V system (a battery is made of cells, lead-acid cell is described here: ).Īnother possibility (most feasible) is to buy a couple-hundred watt invertor and a 24V standalone charger (designed to work with 100-240VAC depending on your location). Stealth1 is a battery charger not a smart switching device therefore not increasing the alternator output to make up for its loses.
If you can find such a transformer, you will only need the rectifier/regulator box from a 24V alternator.ĭC-DC converter is a good option, but again, it has to be designed as a lead-acid battery charger, not just a power source. The alternator output should be between 25 - 40 of your total battery capacity. If this is the case, you could use a step-up transformer with 1:2 ratio, but it has to be designed for this kind of application as changing RPM changes the alternator output frequency and consequently would change the output voltage of a transformer. Most (car) alternators produce AC that goes through a rectifier and a regulator. Well, the best option is, of course, to just buy a 24-volt alternator.
