RV Dual Battery Solar Charger



About RV Dual Battery Solar Charger

This RV Solar Battery Charger Controller is Special Design for RV & Marine & Vehicle & Boat Solar Systems like Camper Van Trailer and Golf Carts equipped with a solar system—this Controller Support Dual Battery Charging (1 Main Battery & 1 RV Starting Battery). 

The 15 Amp Model can handle PV Array Input up to 165W, and the 25 Amp Model can take a Maximum of 350W PV Solar Power Input, Capable of Handle Standard 20 amp Current and a Maximum of 25 amp Current.

Why RV Solar Power System

Living a mobile lifestyle is becoming increasingly popular. More and more people choose to deploy a solar power system to their RV because the gas or diesel generator is loud, inefficient, and not very green. 

But choose a silent, efficient, and green Solar energy to charge the battery that only requires sunlight. 

Also, Sun power is the future, but fortunately, you don’t have to wait until the end to get the battery charged. Once you get a solar system, you’ll enjoy unlimited free and clean fuel to power up your RV Batteries.

Besides AC Power, a renewable car battery charger can offer an affordable, automatic solution for various situations. 

A solar charger on your RV can keep your batteries charged so basic functions like your water pump, 12-volt lights and other devices continue to run even when there are no other power sources. 

While solar panel charging is not the most powerful choice, it is the quietest and most rewarding. 

When compared to running a generator, Solar is superior because it works without requiring any fuel except sunlight.
