Solar charge regulator

A solar charge controller is a device that controls the flow of energy from the solar panels to the solar battery. It ensures that the battery is optimally charged by regulating the voltage and current. The regulator protects the battery from overcharging and overdischarging, helping to extend its life. Some regulators also offer additional functions such as displaying the battery's state of charge and managing several energy sources.

There are two types of solar controller on the market: PWM solar controllers and MPPT solar controllers.

PWM solar regulators are highly efficient and optimise battery charging. They currently offer the best value for money of all the regulators available.


  • PWM regulator

    The PWM regulators are the most used in off-grid photovoltaic systems. They can improve the charge of the battery. To complete the full charge, they separate the current provided by the panels and send it to the batteries in the form of pulses. These pulses are modulated (+ or- long, frequent + or-) by the accurate reading of the regulator to the battery terminals. This allows it to know the charge level.
    The role of PWM controllers is not only limited to fully charge of the battery, they also help to limit sulfation plate batteries thanks to high frequency pulses.
    There are several kinds of PWM controllers, some with basic functions and other more complex, are equipped with software that continuously manage the battery status.

  • MPPT regulator

    The MPPT regulators (Maximum Power Point Tracking) have an advanced technology that constantly searches the maximum power point and thereby get the best performance of the photovoltaic panels. The MPPT increase the energy of an installation, they optimize the charge of the battery and prolong their life.
    The MPPT regulators check the voltage of the panel to find the output point of maximum power. They are able to adjust the voltage supplied by the panel to align it to the voltage that the battery can receive.

  • Box pre wired

    Our pre-wired "plug and play" boxes require no installation. Just plug in the battery and connect the panels. With this system, it is not possible to make mistakes in polarity. The cabinet is delivered fully pre-wired with a 230V outlet and a ventilation grille. If you need more room or are reluctante to do the installation, this package is for you !
