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 the 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 your solar system’s battery charger and protector.

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 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.

If you are already familiar with solar energy, you might have basic knowledge about this renewable energy and its equipment.

A good solar charge controller should have specific features to provide maximum power.

In this section, we include the key features of a solar charge controller that ensure the quality of the device. Let’s explore.

Types of Charge Controller

You have already learned that MWP and MPPT are the two types of solar charge controllers.

You have to consider the type depending on the solar panel and battery power.

If you have a small and medium-sized solar system, MWP is perfect for you. On the contrary, MPPT offers you maximum power point tracking.


You have to install a controller compatible with your solar system wattage and battery voltage.

Some charge controllers have different voltage outputs, and you can use them for multiple solar panels. Ask the seller to get the best option for you.


Advanced solar charge controllers have smart features and several connectivity options. You can connect a modern charge controller via Bluetooth, smartphone app, and PC.

A remote monitoring system enables you to maintain voltage output in the easiest option.

Besides, a smart display system, customized power input and output, automatic voltage detection are the most effective features for solar charge controllers.
