How long does it take to charge a 12v 200Ah battery?

24 hours at the C-20 rate will fully charge a 200A battery, if it has dropped to 100\% depth of discharge or a terminal voltage of 10v. It will take 20 times longer, or around 480 hours, for the lower output charger to do the job.

What size generator do I need to charge my battery bank?

As a general rule, the generator should be around 2 times the size of the inverter’s continuous output.

The capacity of your 12v battery can be described as 12 x 105 Wh. That’s 1260 Wh. Assuming 100\% efficiency (impossible) then your 700 W generator will take 1260/700 = 1.8 hours to generate 1260 Wh to charge the battery.

How many batteries do I need to run a 1500 watt heater?

However this is assuming you will only use solar panels to run a 1500 watt heater. If you combine this with a battery bank however, you will be able to run the heater for longer periods. If you have a 1500 watt solar array you only need 8 200ah 24V batteries to run a heater all day.

How do you charge a portable generator battery?

The best way to charge your battery is to run a proper 240-volt or 120-volt battery charger off the generator’s AC output. This will recharge the battery much faster and accurately.
