Solar charge controllers are used in off-grid solar systems to ensure that batteries are charged at the correct voltage and current.

Whether you need a solar charge controller depends on a few factors. Learn all about this solar tool, including types and benefits.

PWM solar charge controllers tend to be less expensive, ranging from $15 to $40. This lower price reflects the more limited capabilities PWM controllers have when compared to MPPT.

Charge Controllers Help Solar Panels and Batteries Get Along Why this small, overlooked piece of technology is key to setting up your solar and battery system for success.

As the solar panel voltage /current increases, the PWM generator increases its repetition rate thus resulting in increased output current. At the same time, additional voltage is applied to the ...

A solar charge controller is essentially a solar battery charger wired between the solar panel and battery. There’re two main types of solar charge controllers – PWM (pulse width modulation) and MPPT ...

Maximum power point tracking (MPPT) is a method that uses PWM and a special DC-DC converter to match the impedance of the solar panel to the battery.
