North American solar mounting manufacturer Opsun Systems Inc. has launched a commercial flat-roof racking solution engineered to support and house string inverters directly alongside rooftop arrays.
North Carolina-based racking supplier Opsun Systems announced the immediate availability and shipping of its new SunRail Inverter Rack.
Designed to eliminate the unstandardized field improvisation often associated with mounting heavy string inverters on commercial and industrial (C&I) rooftops, the aluminum structure expands on the engineering architecture of the company’s existing flat-roof product portfolio.
The structural engineering properties of the system are optimized for severe environmental loading on low-slope surfaces up to 7°. Manufactured using 6000-series structural aluminum and paired with 306 stainless steel bolts and nuts, the frame is rated to withstand maximum wind loads up to 180 mph and maximum snow loads up to 100 PSF depending on project-specific configurations.
The hardware footprint for a single, standalone inverter rack unit covers 15 square feet of roof space and carries a total base racking weight of 60 lbs, imposing a localized dead load on the roof membrane between 5 to 15 PSF.
