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.
