The Best RV Battery Chargers – What You Need to Keep Your RV’s Battery Charged
Taking advantage of solar power is one of the easiest ways to enhance your sense of freedom on your next RV trip. A high-quality solar charger will allow you to keep your RV battery topped up, while a portable solar power system will give you the ability to charge your electronic devices, without putting excess strain on your RV’s battery.
Running your RV’s engine to make sure the battery does not drain will burn unnecessary fuel, which is both costly and damaging to the environment. On the other hand, solar electricity is completely free and will not contribute to your carbon footprint.
This is why we have decided to highlight some of the best RV solar battery chargers on the market today. We will also go over some of the basics you will need to build a portable, RV-friendly solar array. Stop worrying about power hookups and battery drain and begin enjoying the freedom solar power can add to your RV adventures!
Why do You Need a Solar Charger for Your RV?
Before we go over some of our top recommendations, we should start by explaining why battery chargers are so important for RV enthusiasts.
Given that the battery is at the heart of your RV’s electrical system, it is of critical importance that you do not allow it to fully drain. This is where a RV battery charger can come in handy. For starters, the best battery chargers can be used to charge a drained battery and get it back up to the point where you can start your vehicle’s engine. This is incredibly important, especially in emergency situations where you cannot boost your battery any other way.
The next way battery chargers can help is by trickle charging your battery. Essentially, this means the charger slowly charges the battery, even as power is being drawn from it. Preventing battery drain in the first place is really helpful, especially if you find yourself in a remote location where plugging into the grid is not a possibility.
Why Solar Chargers?
Solar chargers give you the ability to generate your own electricity. Where traditional battery chargers must be plugged in and charged themselves to be of any use, a solar charger can connect to one of more solar panels. The solar panels absorb sunlight and use that energy to generate electricity you can use to charge your battery.
Just think how valuable that would be if you parked your RV in a remote location where there was no access to a camper shore power plugin.
