What Is A Solar Charge Controller?

Solar Charge Controller
Solar Charge Controller

A solar charge controller is a voltage regulator that keeps the battery secure from overcharging and loading. It works between the solar panels and battery to regulate the voltage or current from the solar panel and goes to the battery.

A charge controller also enables users to monitor the power productivity, input, output, battery charging, battery discharging, and more.

Advanced solar charge controllers have various features and communication systems to maintain battery life and protection.

Some charge controllers offer you a remote monitoring system and control the solar system via a smartphone app.

So, solar charge controllers are the battery charger and protector of your solar system.

How Many Types Of Solar Charge Controllers Are There?

PWM and MPPT are the two types of solar charge controllers you can install on your solar system.

Pulse-Width Modulation (PWM) maintains the battery charging system with voltage control options. This controller enables the battery to get fully charged and helps to discharge. With this device, a solar system can reach the target voltage that is required for battery charging. 

PWM controller ensures the battery is charging with maximum efficiency and safety.  It is a cost-effective and long time charging solution for a small and medium-sized solar system.

Maximum PowerPoint Tracking (MPPT) enables the user to establish an indirect connection between solar panels and the battery. It works as a DC-DC voltage converter with overload protection and low voltage prevention. 

MPPT maintains voltage via an adaptive algorithm and adjusts the input voltage automatically to make the solar system most efficient. Though MPPT has the highest charging efficiency, it costs 2-3 times more than a PWM solar charge controller.
