How to choose the perfect charge controller

Who many max / min 300 watts solar panels required ? Can I use 40ah battery on 260 watt solar panel and 45 amp charge controller. Reply. Wesly says. If you have a 100 amp hour battery (lead acid) so you can only use 50ah so 50 x12v = 600ah of power depending on how many hours of sunshine you receive depends on how big of a solar panel
