Tesla ZS Mounting Solutions

Tesla ZS mounting solutions are based on the Zep Groove, a patented module frame profile designed to mate easily and precisely with Tesla ZS components, creating a simultaneous structural and electrical bond with simple drop-in and precision quarter-turn connections. Zep Compatible™ PV modules are certified by Tesla to work exclusively with ZS mounting hardware.

Rockit: Key and Tongue

The Rockit is a feature common to many Zep Compatible™ hardware designs. The Key and Tongue refers to the “front” and “back” side of the Rockit. The Key side inserts into the Zep Groove, similar to inserting a key into a lock. On the other side, the Zep Groove allows PV modules to “drop in” easily onto the Tongue of the Rockit.

Module Drop-In

Tesla Zep Compatible™ modules are typically dropped in with a downward rotation, as shown. The module’s downward rotation creates forced interference with the Zep Groove of the module frame, cutting through the anodized frame to create an electrical bond.
