| Why use a solar charge controller Solar charge controllers are included in most PV systems to protect the batteries from overcharge and excessive discharge. The minimum function of the controller is to automatically assure the battery is fully charged and keep the battery fully charged without damage to the battery.
The basic criteria for selecting a solar charge controller includes operating voltage and the solar panels rated current. A solar charge controller should be able to handle the rated current of all the panels combined. The next criteria is selection of the desired features. Is an indicator required to indicate the solar panel and charge controller is working? Is an LED charging indicator sufficient or would you rather have a meter that displays battery voltage and charging current? Is conformal coating an important feature? Is Gel, AGM, or lead-acid battery selection important? |
