    Benefits:

    • Extend Battery Life - as much as 6-10 years.

    • Easy to Use - Unroll the panel and start charging in seconds.

    • Portable - the solar panel unrolls easily and rolls up into a compact package.

    • Rugged - marine grade connectors and the most flexible and durable solar in the world - stands up to hail and all weather elements.

    • Low Light Operation - provides some power even in hazy or shaded environments.

    • Lightweight - No frames, no special stands or mounting brackets needed.

    • Waterproof - No worry about using in wet environments.

    • Glass Free - Nothing to be broken.

  • Always roll the solar side out, and don’t roll tighter than a 5-inch inside diameter. Rolling the panel too tightly can reduce the effectiveness of the solar panel. The inner roll should measure at least 5” across. 

     

    Use a damp cloth and a mild soap solution to clean the solar panel. Wait a few minutes for the panel to dry before storing it. Always roll with the solar side facing out. Use the attached velcro strip to hold it in place when rolled. Store in a cool, dry environment (temperature range -30 to 60° C).

     

    All connections must be solar positive (red) to battery positive and solar negative (black or blue) to battery negative. Reversing can damage the solar panel. Consult your battery manufacturer if you have questions about the specifications of your battery.

     

    A charge controller is not required if the battery capacity is 100x greater (or more) than the panel output. For example, a 100Ah battery would not need a charge controller if the panel output is 1A or less. If a charge controller is required, please size it appropriately to the panel output.

     

    Operating Voltage and Current are typical values when tested under load at AM 1.5 lighting conditions. Power performance may vary due to temperature, light spectrum, angle to the sun, and other effects (minimum 95% rated when new).

    1. Unroll the panel with the solar side facing up and pointing towards the sun.

    2. Use the grommets on each corner and a tie cord to hold the panel in place and reduce loss or damage from high winds.

    3. Connect the appropriate accessory and cable for the type of device you will be charging.

    Electronics

    1. Connect the 12V Female Car Charger Adapter (RA-2) (included) to the panel.

    2. Use your own USB car charger adapter to connect your device to the RA-2, or use a 2.4A Dual USB 12V Adapter (RA-14B) (not included) to charge USB electronics.

    12V Batteries

    1. Connect panel output to the input of the appropriate charge controller, if required (4.5A, 6A, and 10A charge controllers available) (not included) (see Important Notes section for more information).

    2. Connect the desired cable to the output of the charge controller or panel. Use the 15 ft. Extension Cord with O-ring Connectors (RA-11) (included) or 15 ft. Extension Cord with Alligator Clips (RA-8) (not included) when connecting directly to the battery. Use the 12V Male Car Charger Adapter (RA-1) (not included) when connecting through a vehicle’s cigarette lighter or accessory outlet.

    3. If using an RA-8 or RA-11, connect the red connector to the + battery connection and the blue or black connector to the - battery connection. If using the RA-1, plug it into your vehicle’s cigarette lighter or accessory outlet. Note: in some vehicles, these outlets are not connected to the battery when the ignition is off, so the solar panel will not charge the battery. Consult your vehicle’s owner’s manual for more information.
