A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most batteries need around 14 to 14.5 volts to get fully charged.

There are three types of charge controllers: the basic charge controller using voltage regulator, Pulse Width Modulation (PWM) based and the Maximum Power Point Tracking (MPPT) based charge controllers. Each charge controller works best for a set of parameters.

30 Amp Solar Charger Controller
30 Amp Solar Charger Controller
$30.00

escription:

  • A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time.
  • Advanced digital power supply technologies raise the circuit’s energy conversion efficiency to as high as 98%.
  • Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries.
  • The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.
  • Historical data storage function is available, and data can be stored for up to a year.
  • The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.
  • The controller employs a built-in over-temperature protection mechanism. When temperature surpasses the set value, the charging current will decline in linear proportion to the temperature so as to curb the temperature rise of the controller, effectively keeping the controller from being damaged by overheat.
  • Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the battery’s service life.
  • TVS lighting protection
