The SolarLand 9130W foldable solar charging kit is compact in size. It comes with an aluminum case that protects the solar modules during trasportation. The adjustable legs permit to point the modules at the sun for maximum energy yield.
A charge controller is conviniently mounted in the back of the module to regulate the charge and to prevent overdischarging the batteries. The kit also includes battery clamp and car cigarette style set of cables to facilitate connections.
Foldable kit features:
- 2 x 65 Watt Multi-Crystalline solar panels.
- Heavy Duty anodized aluminum frame and support legs.
- Compact and powerful
- Fold away support legs to angle solar charger towards the sun
- Smart solar controller built in to prevent over charging and over discharging.
- 16.4 ft Extension cable with battery clamps and car cigarette style female connector.
- Includes Aluminum storage/carry case for safe and secure transportation.
- Panel angle can be easily adjusted. Legs fold completely in for storage.
- Heavy Duty Carry Handle easy handling when removed from the bag.

Each time you charge deep cycle batteries with solar panels, it's necessary to use a charge controller in the circuit to protect the battery from over charging, and in some instances from over discharging. The only exception is when using solar panels smaller than 5W. Choosing the most suitable charge controller is simple and only requires two steps:
Step 1 - Voltage selection
Select a charge controller that is compatible with the system voltage. The standard configurations are 12, 24, and 48 volts. If you are wiring your batteries for 24 volts you need a charge controller that is rated at 24 volts.
Some controllers are voltage specific, meaning that the voltage cannot be changed or substituted. Other more sophisticated controllers include a voltage auto-detect feature, which allows it to be used with different voltage settings.
Step 2 - Current capacity
Select a charge controller that can handle the maximum output current of the solar panel (or solar array). The maximum possible current that a PV panel can generate is the “short circuit current,” indicated as Isc in the panel’s label or specs sheet.
It’s recommended to include a safety factor for isolated events as well. For example, a solar panel with a Isc of 7.89 amp could potentially produce an extra 25% on a sunny day with very clear snow pack. (additional light reflected off the snow). This results in a possible maximum of 9.86 amp (7.89 x 1.25 = 9.86 amp). In this case, a 10 amp charge controller would be recommended.
Below you will find a quick guide to choosing the proper charge controller for several popular solar panel sizes.
