Do not exceed the voltage  

and current ratings of the  

Solar Controller

The total current of the solar system is the sum of the short circuit current of the solar 
panels in parallel, multiplied by a safety factor of 1.25. The resulting system current is not 
to exceed the amperage rating of the controller. The voltage of the array is the rated open 
circuit voltage of the solar panels and is not to exceed 28volts. 

The current rating of the solar system is the sum of the Maximum Power Current (Imp) of the 
solar PV strings in parallel. The resulting system Imp current is not to exceed 30A. If your 
solar system exceeds these ratings, contact your dealer for a suitable controller alternative.

ADDITIONAL SAFETY 

CONSIDERATIONS

•   All installations must be performed in compliance with the National Electrical C ode 
    (NEC) and applicable local codes

•   In Canada, installations must comply with CSA C22.1, Safety Standard for Electrical 

Installations, Canadian Electrical Code, Part 1

•  Installation should be peformed only by qualified personnel.

•  Do not attempt to repair the module — there are no user-serviceable parts

•   Do not stand on, drop, scratch, or allow objects to fall on modules as it may damage 

them and void the warranty.

•   Do not place objects on the modules, even for a moment. Doing so could crack a cell if 

the object is heavy or, if one or more cells on the panel are shaded from sunlight, those 
cells can get very hot and potentially damage the object.

•   Do not carry the panels by the electrical cables or junction box

•   If the panel sheet (front or back) is torn, contact with the module surface or frame may 

result in electric shock

•   Damaged hardware (junction boxes, cables and connectors) represent shock and lacer-

ation hazards. Remove these modules from service and contact Go Power! for disposal 
instructions

•   Cracked or damaged metal ribbons in the panel are an electrical hazard. Remove modules 

from service and contact Go Power! for disposal instructions

•   Do not install or handle the modules when they are wet or during periods of high wind

•   Do not allow water to pool on or near the modules

•  

Please keep these instructions for future reference
