Best Solar Charge Controllers: MPPT & PWM Solar Power Battery Charge Controller 2021

Most solar charge controllers require quite a hefty upfront investment, sometimes in excess of $600. The price of the controller, combined with the price of the panels and batteries, means solar system users may be intimidated by the wide range of models available on the market. But there’s good news: it’s relatively easy to figure out what voltage you’ll need to properly service your solar system, whether it be for an RV, trailer, barn, workshop or household.

Every solar-powered system requires regulation to prevent battery damage, which is why we’ve collected a list of the very best solar charge controllers for a variety of uses. From eco-conscious homeowners to self-taught underground bunker builders, anyone using a solar panel larger than small trickle systems needs some sort of battery regulation, which is where solar charge controllers come in.

With a little bit of math, a touch of research, finding and buying the best solar charge controller for your system can actually be quite simple. There are, of course, several important considerations to keep in mind, like safety features, reputation of quality and price point.
