About this item
The XR-LUG is the low-profile grounding lug for XR rails. Drop it into the rail T-slot, run your equipment grounding conductor through it, torque. It connects the array's bonded rails to your EGC at a single point per row (or per the layout your inspector signs off on).
Most installs run a single 10 AWG copper EGC through the XR-LUG and out to the inverter or combiner ground bus. The lug accepts solid or stranded copper.
Even though the UFO mid clamps and BOSS splices already bond rails and modules into the IronRidge Integrated Grounding system, you still need at least one external lug per array to land the EGC. That's what this part does.
UL 2703 listed as part of the XR system. 25-year IronRidge warranty.

EZ Solar Rooftop PV J-Box (Asphalt Shingle)
The JB-1.2 is a flashed rooftop junction box for asphalt shingle roofs. Use it as the transition point between your rooftop module conductors and a conduit run heading to the inverter. The polycarbonate box mounts under the shingle with an integrated flashing skirt, so the roof penetration ends up under the next course of shingles and stays watertight. Rated 1000 VDC, 80 A, with a wire range of 14 AWG to 6 AWG. Type 3R enclosure, fits roof slopes from 2.5:12 to 12:12. One inch is the max conduit fitting size on both the side wall and the floor pass-through, which covers EMT, liquidtight, and most flex sizes you'd run on a residential array. Listed to UL1741 and CSA C22.2 No. 290. Operating range from -35°C to +75°C, which covers Gulf coast attic conditions year-round. Worth knowing: EZ Solar has discontinued the JB-1.2 and replaced it with the JB-F.100. The JB-1.2 still works fine on asphalt shingle and matches existing inventory, but for new designs going forward, the JB-F.100 is the newer part to spec.

IntegraRack BallastRack Frame IR-30
The IR-30 is a single fixed-tilt ground rack at 30 degrees. One frame holds one module (standard residential up to oversized 800W panels). It's 6061-T6 aluminum, ships in a 5"x5"x48" box at about 10 pounds, and the structural assembly goes together in under 2 minutes. The 30-degree tilt hits a year-round sweet spot for most of the lower 48: enough angle to shed snow in winter, not so much you lose summer production. The module slides up and down the frame for ground clearance, so you can clear tall grass, brush, or sand drift without redesigning the rack. You can anchor it four ways: EarthBallast pans (concrete blocks set on the soil), AnchorSpike for soft ground, drilled concrete anchors for slab, or IntegraRack EarthScrews for dense compacted soil. The EarthScrews are the fastest of the four on most sites; we stock those too. Engineered for 150 mph wind and 100 psf snow at the design level. UL 2703 listed for mechanical and bonding. Pairs with most standard solar modules without special hardware kits.

IntegraRack EarthScrew
EarthScrews are the fastest way to anchor an IntegraRack BallastRack frame to dense compacted soil. Drive each 30-inch screw with a standard impact wrench, set the frame leg over the screw head, level the array. No concrete, no curing, no pouring sand. One 10-pack anchors 5 BallastRack frames (2 EarthScrews per frame). Each screw is rated for up to 1,000 lbs of uplift. Test one on-site first to confirm the soil holds; IntegraRack recommends a 1,000 lb pull test before committing to the whole array. These need dense compacted soil with frost depth under 20 inches. They won't work in silty sand, soft fill, or rocky terrain. For extremely dense ground, pre-drill with a 30" SDS-Max carbide bit and add concrete mix to the hole for extra grip. A nice install detail: the screws allow vertical adjustment after they're driven, so you can level the array on slightly uneven ground without re-driving anything. Heavy-duty steel, built to outlast the modules above them.
