We will break down the different types of solar charge controllers in the market and their most important features that can power up your vehicle application. We also explain the financial benefits of investing in a solar charge controller and why it’s a more efficient choice long term.

What Are The Different Types Of Solar Charge Controllers?

Before getting into the different types of solar charge controllers, let’s go over what exactly they are. A solar charge controller is a solar-powered voltage and current regulator and a key part of a solar panel system. They are utilized in off-grid and hybrid off-grid applications to regulate power input from different sources and deliver optimal power output. This power is then used to run electrical loads and charge batteries for vehicles. 

There are essentially two main types of charge controllers you can purchase: Maximum Power Point Tracking (MPPT) and Pulse Width Modulation (PWM). 

MPPT solar charge controllers work by measuring the maximum input voltage of a solar panel and converting it into power voltage that matches the battery voltage. It accomplishes this by taking the high voltage from a solar panel to power up the battery of a vehicle. When you’re using an MPPT, you can use a voltage solar array that is more powerful than your battery system because the charge controller reduces the voltage so that it doesn’t damage the power source.

A PWM charge controller connects the solar array directly with a battery power bank in use. As the battery charges, the solar panel voltage increases, charging the battery more faster and effectively. To operate a PWM charge controller, a 12-volt solar panel is needed to charge 12-volt batteries, so try finding the right match for each battery. A PWM is generally less efficient than an MPPT charge controller, but the highest quality product is usually the best one to use for any situation. 

What Are The Most Important Features Of The Solar Charge Controller?

Solar charge controllers have many important features to consider when using them for your vehicle. They make sure batteries are not overcharged and maintain their efficiency at their highest state of charge without damaging them and ensure that stored power is not sent back to solar panels at night and is only used when you turn on your vehicle. Because of the way they’re used, they are an overall effective measure of the health and longevity of your batteries. 

Other features of a solar charge controller include its ability to use Low Voltage Disconnect (LVD) and Load Reconnect Voltage (LRV). LVD is a load control feature that instructs the controller to disconnect the energy flow of a battery when its voltage decreases. Meanwhile, LRV reconnects loads to receive electricity from the batteries again. 

You can also utilize lighting control to adjust the lights from your vehicle at specific times of the day or night. Solar charge controllers also have meters to display battery voltage and charging stages that are interactive on-screen. Additionally, self-diagnostic alerts and errors help find faults with any short circuit issues, high temperatures, or low battery levels. 

This makes solar charge controllers all the more appealing to use, but here’s why it’s also a good money-saving investment. 

How Is Investing In A Solar Charge Controller Money Efficient?

Certain solar charge controllers can cost more than others, but at Hub Power, we provide affordable products that will work for a long time. Ultimately, the cost of a specific solar charge controller depends on how much power you need and the vehicle you’re using. Larger vehicles will require charge controllers with more power to operate them. Regardless of the price, you will save more money in the long run because you won’t have to buy as many chargers while using balanced levels of renewable solar power energy to power your vehicles.
