5.4 GROUNDING 

1.   All module frames and mounting racks must be properly grounded in accordance with the National Electrical Code 

and any local jurisdictions.

2.   The modules are required to be grounded, and the module installation needs to comply with all local electrical codes 

and regulations. Additionally, the grounding connection should be made by a qualified electrician.

3.   Proper grounding is achieved by bounding the module frame and all metallic structural components together using 

a suitable grounding conductor. The grounding conductor or strap may be copper, copper alloy, or another material 
acceptable for use as an electrical conductor per respective National Electrical Codes. The grounding conductor must 
make a connection to earth using a suitable earth ground electrode.

4.   Where common grounding hardware (nuts, bolts, star washers, split-ring lock washers, flat washers, etc.) is used 

to attach a grounding/bonding system, the attachment must be made in conformance with the manufacturer’s 
instructions of grounding devices used in the system.

6   Common hardware items such as nuts, bolts, star washers, lock washers and the like have not been evaluated 

for electrical conductivity or for use as grounding devices and should be used only for maintaining mechanical 
connections and holding electrical grounding devices in the proper position for electrical conductivity. Such devices, 
when supplied with the module and evaluated through the requirements in IEC and UL standard, may be used for 
grounding connections in accordance with the instructions provided with the module.

7.   Boviet Solar recommends the method below: 

1.   A grounding kit with M4 size SS cap bolt, M4 size SS flat washer, M4 size SS cup washer, and M4 size SS nut (with teeth)  

is to be attach a copper grounding wire to a grounding hole pre-drilled on the frame. 

2.   Attach the wire between the flat washer and the cup washer. Ensure the cup washer is between the frame and the wire 

with concave side up to prevent corrosion due to dissimilar metal. Tighten the bolt securely using the SS nut with teeth  
(a wrench may be used in this application.) The tighten torque should be 2-3N*m.

8.   Alternate grounding options built into the racking system are acceptable as long as they have been UL approved.
