If A battery is directly connected to a solar array, 2 bad things can happen to the battery: When a PWM charge controller is connected to a battery, it limits the current fed to the battery by the solar panels or drawn from the batteries by the loads.Īlso, at night when the voltage of the battery is higher than that of the solar panels, the PWM charge controller prevents the solar panels from draining the battery.īut what would happen if solar panels are connected directly to the battery? These devices connect the solar panels to the battery to prevent it from overcharging and over-discharging. PWM (Pulse Width Modulation) solar charge controllers are electronic devices used in solar energy systems to protect the battery. What is a PWM charge controller why do we use it? In this article, I’ll explain what a PWM charge controller is, how it works, why you need one, and how to choose the right one. Compared to MPPT charge controllers – another type of solar charge controller- they are very cheap and accessible. PWM charge controllers are probably the most used type of solar charge controller in small off-grid systems.
