SunRail Inverter Racking (IR)

Universal SunRail Inverter Racking (IR) solution for tilted or flat roofs, ballasted or anchored.

IntertekCe

Key specifications

Material

Aluminum rails and components, stainless steel bolts & nuts

Max Snow Loads

Can be designed for any snow loads (up to over 100 PSF)

Max Wind Loads

Can be designed for any wind loads (up to 180MPH) and high-rise buildings

Tilt Angle

Flat (Typical), 5-90 deg. As per manufacturer's recommendations

Inverter Orientation

As per manufacturer's recommendations

Inverter

Most standard string inverters

Roof Type Compatibility

Any roof type (Asphalt, corrugated metal (barn), standing seams, all other custom roof)

Ballast or anchored?

Both. Can be 100% ballasted or 100% direct attachment (lag bolts, hanger bolt, standing seam clamps, corrugated metal roof SMC Clamp)

Dead Loads on roof

5-15 PSF

Pressure on roof

Customizable, options at 100 PSF or less max pressure under the rubber pads available

Inverter height from roof

Customizable, starts at 4 inches, as per manufacturer's recommendation

Grounding

Grounding lugs conforming to UL 2703 available, certification to come.

Ultra Flexible

Our designers and engineers can create an inverter rack for your project, for any commercial string inverter types. Typical designs can be flush (0 deg. tilt), or tilted at 5 to 90 deg. Any common roof type. Any wind loads, any building height, ballasted or anchored. We will create a rack that matches your needs.

Easy to assemble, lots of adjustments

Our inverter racks are similar to our roof racking systems, and use the same simple hardware with one standard bolt type. Racks can be preassembled by Opsun prior to delivery.

Complete turn-key engineering services

Our engineers will review the building's roof plans and create a custom inverter rack that matches the projects requirement. We provide detailed, project-specific plans that details installation steps. We can provide a P. Eng. Stamp for all U.S. states and Canadian Provinces.

Advantages

Can be mounted on Opsun Racking System

Our designers can add the inverters directly on the Opsun PV racking rails, for reduced project costs, and compliance with module-level disconnect, in most states.

Sunshade Options

Aluminum cover (sun shade) can be added as an option to prevent UV degradation of the inverters.

Full Aluminum Design

6000 series aluminum and 306 stainless steel bolts and nuts guarantee maximum durability of the structure for decades.

Fully Adjustable System On-Site

All components can be slid in the rails' channels, to adjust for roof unevenness.

Typical Installation Time

10-20 minutes

Highest Standard for Engineering & Support

Our engineers use only the safest methods of calculation, to assure maximum solidity and durability of the structures. We have proprietary, recent wind tunnel tests with Western University, and we design using the latest Building Codes (ASCE-7-16, NBCC 2016, IBC 2018), as well as SEAOC PV2 notions of array size versus roof size to account for extraordinary vortices. Minimal deflection allowed on rails, and finite element analysis done with high-end 3D engineering software. Each zone ballast & anchors calculated individually. We find solutions to each unique challenge, and we react quickly if unforeseen events happen during construction (such as unmarked drains, roof equipments obstruction and last minute changes).
