Charging the Battery Bank
During the testing of the UPS system I drained the batteries rather low. To recharge the batteries I can either run the Diesel engine of the truck and use the alternator or I can use a smart charger that uses mains power. The battery bank is rated at 345 Amp hours at 24 Volts which takes several hours to charge. The alternator on the truck seems to output an average in the neighborhood of 50 amps at 28 volts while the car charger can only output 15 Amps at 14 volts.
Sorry for the shaky camera work, I didn’t have any of my usual weights or stands with me.
