I am new to solar and just getting my feet wet. I purchased a Renogy 50watt mono panel and PWM10CC and now I shopping for a
battery and looking to minimize my cost. My intent is to run a 12V car fan (approx 0.5amps) when the sun is out. (Think power failure in hot weather.) I am thinking about buying a 12V AGM battery in the 7amp-hr to 10amp-hr range instead something larger like 35amp-hr. Is this acceptable? I know that the maximum charging current for a battery is a function of the amp-hr so will the PWM10CC exceed the maximum charging current of a small battery and cause overheating and bubbling etc...? And if there is no safety issue is there any shortening of the battery life? Although that is a minor concern because the small amp-hr batteries are inexpensive.
Thanks for any help.
