Charge Controllers

The charge controllers are used in off-grid and grid-tie with battery backup systems. The charge controller is an electronic voltage regulator that is used to limit the rate at which electric current is drawn in or out of the batteries. The simplest charge controllers turn off the charge when the battery reaches the optimum charging point and turns on when it goes below certain level. It fully charges the battery without permitting overcharge while preventing from reverse current flow. The overcharge or overvoltage may reduce the battery performance or lifespan and may pose a safety risk. Some charge controllers can show system operation parameters, battery status and protection from over discharging.
 

The capacity of charge controllers ranges from 4 amps to 80 amps. Most charge controllers use Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT) technology. PWM controllers are a time-tested technology that has been around for many years. Although efficient, there is no comparison with MPPT. MPPT controllers track the maximum point of power (constantly scanning the VI curve) thousands of times per minute.
