...) / Voltage(Volt). In case of your solar panel setup, the charge controller's max current should be at least 120W / 12V = 10A. However, I don't think this calculation applies to the case of charging batteries using generator (the battery's resistance would play a role). Check these related discussions on charging b...

Quoting: TomChumRe: 13.8v to charge batteries. That seems just barely adequate. Right! Motor vehicle charging systems do put out that 13.8 v as a rule and it works for them as most of the time a motor vehicle battery is not discharged very much in normal use. A PV / alterna...

Add voltage in series strings or amperage in parallel strings of batteries Bulk charging rate should be around 10% of the bank capacity, the charger will allow you to dial back the max current to match your battery bank. That will requir...

...nYes, you need a battery charger that you power with the 120 VAC output from the generator. The manual for that generator probably lists the 12 DC as an output. My Yamaha specifically ststea not for charging batteries. As mentioned above the output voltage is too low for charging. It is also too low an output to do anyth...

... Running the Black&Decker charger from the 110v outlet, I was able to charge at 15.4A (almost twice the speed at 8.5A) and get the additional benefit of the automatic charge controlling the rate; and also the charger will tell me when the battery is full. It was charging at 15.5volts at 15.4Amps which equals 238Watts, easily within the capacity of the little 1000W ...
