Charging Your Batteries on Open Water

Charging Your Batteries on Open Water – The Best Solar Battery Chargers for Boats

 Making sure you have the ability to charge your electronic devices while you are away from land can be a difficult task. Having the ability to charge your boat’s batteries and power your electronic devices while you are on open water is also incredibly important, especially from a safety perspective.

This is where solar electricity comes in handy. Today, solar panels, solar inverters, and solar batteries are more efficient, lightweight, and affordable than they have ever been before. This is why they are becoming so popular with recreational sailors and boaters.

Not only can solar panels give you access to limitless source of renewable energy, you can now find modern solar accessories that are waterproof and completely practical for boaters.

How Can We Help?

If you are interested in investing in a solar power system for you boat, we are here to help. Knowing what you need and which products to choose can be somewhat overwhelming, which is why we are going to go over some of the best boat-friendly solar chargers and solar panel kits on the market today.

In addition to highlighting some of the best solar battery chargers for boaters, we will also explain some of the components you will need if you are looking to assemble a full solar power system for your boat.

Each of the products we have chosen to highlight was selected because they find the perfect balance between performance and affordability. They were also chosen because they have boat-friendly features, like water resistance, convenient carrying handles, and lightweight designs.

 How are Solar Battery Chargers Useful for Boaters?

You might be wondering what a solar battery charger is and why you would need one for your boat, which is why we are going to quickly explain what they do and how they can be useful.

In simple terms, solar battery chargers use solar panels to absorb energy from the sun and turn it into useable electricity. The energy your solar panels collect then flows into a charge controller, which is a convenient device that can store and distribute that electricity as you require.

While some charge controllers contain built-in batteries, many boaters also invest in a separate high-capacity battery bank, which can store a greater amount of this solar electricity.

If you are wondering what you can use this newly collected solar electricity for, the answer is just about anything. While some will keep a solar battery charger and a set of portable solar panels on board in case of emergencies, or simply to charge their boat’s battery in the event it completely drains while away from land, others will use them simply to charge their portable electronics.

In either case, being able to access a limitless source electricity while you are on the water and far away from the plug-in outlets found at a marina is incredibly convenient.

The way you use your solar charger and the other components of your solar power system is up to you. Whether you want to stow a small solar charger away for emergencies, or you own a larger boat and want to assemble a more permanent solar power system, we can help point you in the direction of some high-quality products.

Stop worrying about draining your batteries while you are away from land and embrace solar power today!

 The Best Solar Battery Chargers for Boats

The following portable solar battery chargers were selected because they are perfect for boaters. While they are also enjoyed by RV drivers and camping enthusiasts, the fact that they are versatile and highly portable also makes them the perfect solar accessory for any boat owner.

If you are looking to use solar energy to power appliances, or your boat has significant power needs, you may want to look into a solar inverter. A solar inverter will allow you to turn the DC power your panels collect into usable AC power, like you would access through your home’s wall outlets. 

Browse our collection of high-quality Solar Power Inverters to find exactly what you are looking for. We carry solar inverters from all of the top brands, including Go Power, AIMS Power, Outback Power, and more.
