People gravitate towards boondocking for many reasons, but one of the most often cited is avoiding the noise of typical crowded campgrounds. However, there’s nothing peaceful about firing up a propane or gasoline-powered generator. How can you juice your devices and keep the lights on and the water pump running? Investing in one of the best solar battery chargers for your RV is a wise choice. 

These devices used to be pricey, but now they’re affordable for nearly anyone into the lifestyle. As they don’t power everything in your rig, like your HVAC system, you don’t need anything elaborate — a single trickle charger will do. 

Are you ready to outfit yourself for your next adventure? Here are the best solar battery chargers for your RV. 

Types of Solar Battery Chargers for Your RV 

First, we need to define the systems shown below. There are four levels of battery chargers, and we’ll primarily be discussing the third tier in this article:

  • Trickle chargers: These provide only 10 to 50 watts and keep your battery from dying while your RV sits in storage. Many portable solar kits with charge controllers can double for this purpose. 
  • Light chargers: These consist of 50-100 watts, just enough to let you run your RV’s lights at night, although they won’t power larger appliances or computers. 
  • Portable solar kits: These are the focus of his article. They consist of 100 to 600 watts with sufficient juice to run your RV’s lights and DC appliances like your furnace, water heater and fridge. A separate inverter can run AC devices like computers and TVs, and many kits have ports for charging gadgets. 
  • Full RV solar systems: Consisting of 600 to 4,000-watt chargers. These require an array of panels, inverters and charge converters integrated into your RV’s electrical system. Most people pay a professional or purchase an RV outfitted such, although a talented DIYer can get the job done. This setup allows you to run everything you can at home, including your AC, multiple computers and appliances. 

Advantages of Solar Battery Chargers 

Generators create tons of noise. Their emissions contribute to climate change while making your campsite smell like fuel. Ugh. Furthermore, all that racket scares away any wildlife you might hope to see, making it hard to hear your partner’s voice or listen to that scary National Parks Mysteries podcast you downloaded as you sit around the campfire. 

Conversely, your RV’s best solar battery chargers are as silent as a purring kitten. They’re also clean and green, producing zero emissions to minimize your carbon footprint. You can enjoy your favorite boondocking destination guilt-free as long as you pickup your trash and leave no trace. Seeing the stars under a dark sky alone is a treat — gazing up at them in perfect silence is the ultimate in off-grid bliss. 

Components of an RV Solar Battery Charging System

The best solar battery charging systems for your RV consist of three components: 

  • Solar Panel: These may be single or folding. 
  • Charge Controller: This device prevents your battery from overcharging and suffering damage. 
  • Inverter: Regulates the flow of electrical power. 

5 Best Solar Battery Chargers for Your RV

One advantage of this system is its compatibility with a wide array of sealed, gel, flooded or lithium batteries. Monocrystalline panels are smaller and lighter than poly, meaning you can use this system on other toys, like a boat.
