    Information about PWM charge regulators

    PWM Charge Regulators for 12V, 24V and 48V: A large part of the charge regulators sold at WccSolar are voltage regulators, this means that they are suitable for installations at either 12V, 24V or 48V, regardless of the voltage we are using in our photovoltaic solar installation. No type of voltage selection will be necessary prior to installing this type of solar regulator, the same solar regulator will read the voltage of the batteries and make the adjustment, thus having a solar charge regulator that automatically adapts to the voltage.​

    Can I install a PWM in my photovoltaic installation?

    In PWM type regulators, the voltage value of the working field is the same as the voltage at which the batteries work.

    When a PWM regulator is installed in a photovoltaic system, it is important to take into account:

    • The panels compatible with PWM regulators are 12V and 36 cells or 24V and 72 cells solar panels.
    • PWM regulators have a maximum load intensity, if we exceed this value the regulator will burn out. Therefore, we must carefully select the regulator to use, always leaving a margin that always gives us some flexibility in the face of low or high working temperatures.
    • The working voltage of the photovoltaic field must always be at least 2V higher than the working voltage of the batteries, otherwise the charges will not be carried out completely. Therefore, the optimal values ​​should be greater than 14.4V for 12V installations and 28.8V for 24V.
    • When making the connections we must always connect the batteries first and the solar panels last. When disconnecting, the process will be carried out in reverse, opening the panel fuses if we have them or failing that, disconnecting the regulator terminals and subsequently disconnecting the batteries.
    • PWM type regulators usually have working voltages of 12V/24V interchangeably, 48V models, on the contrary, in most cases are specific for that working voltage.
