Charge Controllers
Do you need a charge controller the simple answer is yes! Charge controllers are devices used to protect batteries from damage due to overcharging. They limit the voltage and current delivered to a battery by solar, wind or microhydro generation.Modern day controllers with sophisticated microprocessor-based circuitry have all but replaced the older on / off type controllers. When choosing a charge controller for your system keep in mind that you may want to expand your charging capability in the future. A larger controller may be a wise investment.
