Solar Regulators - PWM
Every solar panel in an off-grid system will need a solar regulator. To read more about the importance of choosing the right solar regulator for your system, please visit our information page on the subject.
We sell a range of solar controllers from Victron, EPSolar, Morningstar and Steca - all reliable, well-proven units. These basic solar regulator units work on pulse width modulation (PWM) - a type of charging regime that rapidly pulses the charge from the solar panels to maintain the battery voltage at a constant level. This method of charging allows maximum charge into the batteries, but prevents overcharging. If you require an MPPT controller - please click here.
All of our solar charge controllers come with the standard electronic protection features, to protect all the working components in your off-grid system. Different controllers have separate displays available, or integrated into the controller for easy setup functionality.
If you need more help with choosing the correct controller for your off-grid setup, please get in touch.
