IMPORTANT SAFETY INSTRUCTIONS 

 

 

• 

All electrical installations shall be done in accordance with the local and national 
electrical codes ANSI/NFPA 70. 

 

• 

The PVI13KW contains no user serviceable parts.  Please contact Solectria Renewables 
or a Solectria Renewables authorized system installer for maintenance.  (See page 37 for 
Solectria Renewables contact information and authorized system installers.) 

 

• 

Before installing or using the PVI13KW, please read all instructions and caution 
markings in this manual and on the PVI13KW unit as well as the PV modules. 

 

• 

Connection of the PVI13KW to the electric utility grid must be done after receiving prior 
approval from the utility company and performed only by qualified personnel. 

 

• 

Completely cover the surface of all PV-arrays with opaque (dark) material before wiring 
them.  PV arrays produce electrical energy when exposed to light and could create a 
hazardous condition.
