SOLAR CHARGE CONTROLLER

Solar Charge Controller is an electronic device that manages the power going into the battery bank from the solar array It ensures that the deep cycle batteries are not overcharged during the day and that the power doesn’t run back to the solar panels overnight and drain the batteries. Some charge controllers are available with additional capabilities, like lighting and load control, but managing the power is its primary job.  solar charge controller is available in two different technologies, PWM and MPPT. An MPPT charge controller is more expensive and highly efficient than a PWM charge controller.

MPPT CHARGE CONTROLLER

  • An MPPT solar charge controller stands for “Maximum Power Point Tracking”. 
  • It will measure the Vmp voltage of the panel and down-converts the PV voltage to the battery voltage.
  • When the voltage is dropped to match the battery bank, the current is raised, with a 20V solar panel, you can charge a 12V battery bank.  

FEATURES OF CHARGE CONTROLLER

  • Multistage charging of battery bank - changes the amount of power set to the batteries based on its charge level, for healthier batteries.
  • Reverse current protection - stops the solar panels from draining the batteries at night when there is no power coming from the solar panels.
  • Low voltage disconnect - turns off the attached load when the battery is low and turns it back on when the battery is charged back up.
    Lighting control - turns attached light on and off based on dusk and dawn. Many controllers are configurable, allowing settings for a few hours or all night, or somewhere in between.
  • Display- may show the voltage of battery bank, state of charge, amps coming in from solar panel.
