12 Volt Portable Solar Chargers

12 Volt Portable Solar Chargers

One of the best ways to preserve and extend battery life is to provide a maintenance charge when the batteries are not in use. All batteries discharge themselves over time. Some faster than others, causing them to lose as much as 10% of their charge each month without any load connected. Batteries left in a state of partial charge can freeze in the winter or sulfate during summer rendering them useless or, at least, shortening their life considerably. A solar charger generates power each day keeping the batteries at full charge.

We have three models designed and built for those on a budget. Compared to lower quality portable solar systems from other manufacturers, the Solarland Economy Series features ‘A’ grade solar panels. These high efficiency ‘A’ grade panels feature low temperature coefficients and sturdy frames designed specifically for portable use. All three of our portable chargers carry two year warranties on entire assembly and guarantee 80% output for 25 years. They produce more amp/hours/day than other, lower efficiency types that may cost less. The Economy Series is designed to be completely compatible with any 12V battery system. The built-in, three stage, PWM type charge controller is included and regulates the power flowing to the battery protecting it from overcharging. Indicator lights on the controller confirm proper operation while in use. It’s capable of safely charging both sealed and flooded batteries ensuring compatibility with Lead-acid, Gel, and AGM battery types. 5 meters of cable connect the portable solar panel to the battery bank and a fuse is included for safety. Four different battery connection devices are included with every kit enabling simple connection to the battery no matter what the configuration. For safely storing your portable solar system, a padded carrying case is included to protect the system from damage. (See details below for additional technical information).

An MPPT controller optional upgrade is available allowing for 15 to 30% more charging daily.

High-Speed MPPT: Always on Target
Not all Maximum Power Point Tracking controllers were created equally. Most use a sweep and sleep method that scans the entire voltage range every 30-60 seconds. That’s okay for a clear day, but traditional controllers are constantly off target during changing cloud conditions – exactly when power is scarce and needs the most. Genasun controllers adapt to changing light conditions 20 times every second. They are always on target, capturing every bit of available sunshine. Simply put, other controllers can’t keep up.

Computer-controlled, 4-Stage battery charging
Precise computer controlled charging ensures the optimal charge cycle for your battery. This increases the battery life, and maximizes battery capacity.
