FAQs to Your Solar Battery for RV

What Battery Is Recommended For My RV?

Answer: Use a deep-cycle battery for your RV instead of a typical automotive battery. Because deep-cycle or marine battery can repetitive discharges up to 50 percent or more. They provide rated capacity even after hundreds of cycle life. Also, this type of battery can work in high temperatures and be combined with more reserve capacity. 

How Do I Connect My Panel To My Battery?

Answer: Solar panels and batteries are connected through a regulator. Regulators are used to accept voltage from the solar panel and output the useable voltage to charge batteries. Each panel/regulator comes with a set of instructions to make the connected devices. Follow those instructions and start generating power from the solar panel for your batteries.

Do I Need A Charge Controller?

Answer: The primary purpose of using a charge controller to prevent your RV batteries from overcharging. Overcharging any batteries can shorten their life tremendously. It will charge batteries up to a preset voltage point, and after reaching the end, it will automatically turn off charging. It also provides charges at the highest state, even with the least amount of water consumption. 

Will The Tiny Solar Array That Came With My RV Charge My Batteries?

Answer: It usually relies on how much electric power you want to generate. Usually, the solar panels that came with RV can charge batteries. But those solar panels might take a huge time because they are given to protect batteries from dead when you don’t use them for a long. So it is better to install an additional solar panel to cope with day-by-day recharging.
