Zep System I
- For tile-roof applications
Zep System I™ offers the fastest and least expensive way to install PV arrays for flush-mount tile roof applications. With its ability to optimize attachment point spacing in both east-west and north-south axes, Zep System I can offer a 25% reduction in roof attachment points — dramatically reducing the amount of time spent on the roof. With a series of drop-in, rock-in, and quarter-turn connections, Zep System I in- stalls without the use of lengthy rails and separate grounding hardware and is universally adaptable to third-party roof attachment solutions such as tile-hooks, hanger bolts, and flashed standoffs.
Components
 |
Spanner Bar, 850-1192 The Spanner Bar is a snap-together component that spans between and connects to tile hooks or flashed attachment hardware and provides attachment point flexibility in both nominal east-west and north-south axes. |
 |
Bar Sleeve, 850-1143 At the end of a run of Spanner Bars, the Bar Sleeve provides a point of attachment for the Cam Foot. |
 |
Spanner Clamp, 850-1194 The Spanner Clamp provides a means of attachment between the Spanner Bar and the roof attachment hardware. |
 |
Cam Foot, 850-1242 The Cam Foot creates a structural connection between the Spanner Bars and the module frame and allows for precision height adjustability. |
 |
Interlock, 850-1178 The Interlock provides north-south and east-west structural and ground bond connections creating a structurally contiguous hyper-bonded array. ETL Listed to UL1703 |
 |
Universal Box Bracket, 850-1196 The Universal Box Bracket allows rapid attachment of electrical boxes to the perimeter of the PV array. Compatible with most residential-scale transition, junction, and combiner boxes. |
 |
Wire Clip, 850-1222 The AC/DC Cable Clip provides a rapid and effective means of securing array wiring by snapping into the Zep Groove and sliding to create the perfect tension. It offers both sleeved and strain-relief connections and is capable of holding both DC and AC (micro-inverter) wiring. |
 |
Ground Zep, 850-1172 The Ground Zep provides a point of connection between the PV array and the equipment grounding conductor. One Ground Zep is required for every 72 PV modules. ETL Listed to UL467. |
 |
Array Skirt End Cap, 850-1216 The Array Skirt Cap Set provides an aesthetic cover for the exposed end of the Array Skirt. Made of anodized aluminum, each set comes with two Skirt Caps. |
 |
Array Skirt Enhancing both function and aesthetics, the Array skirt facilitates easy front-row installation while providing a clean look at the front of the PV array (available in both clear and black finish). |
 |
Enphase Connector Bracket, 850-1209 The Enphase Connector Bracket offers a quick and effective means of securing Enphase Energy's Engage Drop Connector directly to the Zep Groove without the use of tools or separate fasteners. |
