Best Solar Charge Controller

Your solar power battery can soak up a lot of charge, and the sun’s rays will recharge it over time to full capacity. However, there is a risk that the sunlight will actually overcharge the battery, causing damage to it and creating all sorts of problems for you. That’s why it is important to get a decent solar charge controller to regulate the battery charging and prevent your system from burning out.

What to Consider before Buying

Before buying any of the solar chargers on our recommended list, there are a few things you need to take into consideration:

  • Not everyone needs a solar charge control- According to Northern Arizona Wind & Sun, some solar systems won’t need the controller, and in some environments, this extra piece of equipment is unnecessary.
  • Know your area- If you know how much sunshine your solar panels are getting and how much power they are absorbing, then you will have a pretty good idea of whether you need a controller and what kind controller will be necessary. If there is only a little extra energy you need to account for, then you probably don’t need a very expensive or high-quality controller. Something simple and cheap may do just fine.
  • Read the reviews- We have reviewed 10 controllers for you, but it is important to read what other customers are saying about the controllers and how well they work. That should give you some idea of how they will work for you and if you should be choosing one or the other.
