![]() ![]() The ABSORPTION stage (the remaining 20, approximately) in the AGM/flooded 24 volt charger has the charger holding at the absorption voltage (between 28.8 VDC and 29.4 VDC, depending on charger set points) and. He charges this battery with a 950 watt of solar power system and a robust DC-DC alternator charging system. The negative diode is wrong way around so will do nothing, if the other way around the alternator will short via top diode. The target voltage for a 24 volt charger for AGM or some flooded batteries is 2.4 to 2.45 volts per cell, which is 28.8 to 29.4 volts. Steve’s DIY camper, called Maximus, features a massive electrical system centered around a 24 volt, 1,100 amp hour lithium battery bank and a buck converter that converts the 24 volts to 12 volts for some of his loads. I dont see how Bruce Harveys circuit can work. ![]() Due to the A2Bs internal splitting system there is the. Buy Battery Tester Battery Analyzer Alternator Analyzer Charging System Test Alternator Diagnostic Tool 6V/12V/24V Alternator Analyzer 2.8in TFT Screen. ![]() 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. This low voltage (at high current) is amplified to a 4 stage charging profile at the domestic bank. I tried a buck booster to 29v but found one battery would start taking most the charge. If the voltage stays about a volt higher than resting voltage (e.g., about 13. 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). Then increase the engine RPM to about 3500 as you watch the reading on the multimeter. 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. 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. The 33/34 SI series alternator is a brushless, heavy-duty integral charging system with built-in diode rectifier and voltage regulator, producing DC current. Well, the best option is, of course, to just buy a 24-volt alternator. ![]()
