No one in their right mind would attempt to fully charge a battery bank by running a generator, unless they have no choice. Acceptance rate becomes about 12.5 amps per 100 amp-hours of storage at 85% state of charge. Most folks charge from 50% to 80% and call it good. Then when they have shore power the bank gets fully charged.
You may be a candidate for a solar system if all you wish to do is charge the battery bank.Dirtpig wrote:
This is very good info, thankyou everyone. I will check the voltage of the batteries the next time i plug it into power when they are down 50% and see what the voltage goes up to. I would only want to run the gen for an hour or two so if its going to take up to 24hrs to recharge then i will definitely need to upgrade that converter.
I have a 300 watt solar system with a bluesky 30 amp pwm controller which I set the absorption voltage to 14.8. I have 2 trojan t-105. Reason for wanting a generator is to get through 3 nights of camping in winter time. Ideally I'd like to only have to run it a couple hours a day. My battery usage is low. The furnace is biggest sucker of batteries (0-6deg Celsius outside in winter). Unfortunately the solar does nothing for me in winter months as it is usually dark clouds or trees will block out sun.
