IMPORTANT SAFETY INFORMATION

WARNING Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference. The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

Installation Precautions
  1. Install all sensitive electrical components (including wiring connections, regulator, and battery) inside a weatherproof enclosure to prevent electric shock.

  2. Do not wire multiple panels in series. If you need to connect two or more solar panels together, this work must be done by a qualified electrician unless they are connected through a regulator.

  3. This solar panel kit is not designed for tie-in to a grid. Only a licensed electrician and a licensed building contractor can safely design and implement a grid tie-in system. Any grid tie-in system must meet all applicable building and electrical codes, and must meet standards established by the area power company. Improper grid tie-in can result in electrocution, fire, and other serious personal injury and property damage. An incorrectly installed grid tie-in system can cause feedback voltage, resulting in electrocution of electrical utility workers.

  4. Do not apply pressure or press down on the Solar Charger when it is folded.

  5. Do not focus light on panel.

  6. This product may occasionally produce more current and/or voltage than its rated output. Increase output ratings by 25% when determining component required voltage and amperage ratings. Refer to Section 690-8 of the National Electrical Code for an additional multiplying factor of 125 percent (80 percent derating) which may apply.

  7. Do not attach to battery or power grid without proper regulator, inverter, and/or charge controller.

  8. Install and use according to applicable National Electrical Code (NEC) standards.

  9. Verify that installation surface has no hidden utility lines before drilling or driving screws.

  10. Install only according to these instructions. Improper installation can create hazards.

  11. Wear ANSI-approved safety goggles and heavy-duty work gloves during installation.
    Do not wear jewelry or metal watches when working near solar panels, wiring or batteries.

  12. Keep installation area clean and well lit.

  13. Keep out of reach of children.

  14. Keep bystanders out of the area during installation.

  15. Do not install when tired or when under the influence of drugs or medication.

Service Precautions
  1. Disconnect items being charged before cleaning.
  2. Do not allow children to play with or near this item or electrical components.
  3. Inspect before each use; do not use if damaged, parts are loose, water is found inside the housing, electrical insulation is cracked or damaged, or connections are loose.
  4. Maintain product labels and nameplates. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
