S-5! Connects With the Newest S-5-PV Kit

The S-5-PV Kit was one of the first solar attachment products to be listed to UL subject 2703, a standard that covers both bonding and mounting.

In order to meet the UL requirements, the S-5-PV Kit had to be submitted for rigorous tests, being evaluated under the severest of conditions to confirm that the product would withstand the elements while maintaining electrical conductivity.

Furthermore, the S-5-PV Kit has gained an ETL Listing to UL 1703. UL and ETL listings are widely recognized by most Authorities Having Jurisdiction, which means fewer inspection hassles for installers.
