solar charge controller

The best MPPT Solar Charge Controllers will efficiently manage the energy between your solar panels and your batteries. This, of course, over-simplifies solar chargers. Nevertheless, they are essential components, and this article will provide the information you need to choose the one right for your system.

Understanding how solar chargers work and the differences between the types of controllers is, whether an MPPT or PWM solar charge controller, is important. Determining the size you need, along with important features, is also included in this article.

How to Select a Solar Charge Controller – What Size You Need

There are two main things to consider before buying a solar charge controller.

  1. The voltage size of your battery array and inverter.
  2. The maximum current your solar panel array can deliver.

This explains these well and breaks down the topics, making them easy to understand.

Solar Charge Controller Choices

There are many suitable charge controllers on the market. Below are five that consistently get good feedback and are manufactured by companies that have been in the solar business for years.

1. Victron Energy MPPT 100V 12/24V Charge Controller
