If you have ever thought about switching to a solar-based home power solution, the chances are that you have come across the term MPPT charge controllers. But, first, let’s talk about solar charge controllers in general as that will give you a basic idea about what they are and what they do.
A solar charge controller is a solar-powered voltage and current regulator and is used to regulate power input from PV arrays for optimal power delivery – thus, helping run electrical loads and charging batteries.
Now coming back to MPPT charge controllers, what is an MPPT charge controller?
An MPPT charge controller, also known as Maximum Power Point Tracking charge controller, are controllers that help track the power for the maximum powerpoint. The maximum power point is the ideal voltage at which maximum power should be delivered with minimal loss in power. Therefore, you can refer to it as peak power voltage.

How Does an MPPT Charge Controller Work?
The voltage of a battery varies according to its charge content. MPPT charge controller works in two ways:
- It increases the output voltage of the solar panel
- It decreases the voltage of the battery
The MPPT checks the output of the PV module and then compares this output with the battery voltage to better charge the battery by converting the output to the best possible voltage to deliver maximum current to the battery.
Over the last few years, charge controller technologies have progressed considerably – and one such innovative technology is PWM charging. Let us now understand the basics of PWM charge controllers.
What are PWM Charge Controllers?
PWM (Pulse Width Modulation) charge controllers are amongst the most common form of charge controllers that are available in the market. As your battery approaches capacity, PWM controllers gradually reduce the amount of power coming into the batteries as it reaches its capacity (fully charged). PWM controllers retain a ‘trickle’ mode, meaning they continually deliver a small amount of power to keep the battery charged.
