Bentek Solar, a leader in Balance of System (BOS) design and manufacturing for commercial and utility scale solar PV products, has received UL 1741 listing and CSA 22.2 certification for its Multiple Disconnect Safety System (MDSS).

"For most commercial and utility scaled installations, it is more economical to install one compact MDSS with up to eight integrated disconnects vs. eight individual disconnects. The MDSS can provide significant benefits in labor, materials and time, resulting in up to 30 percent savings in total costs," said Mitch Schoch, President & CEO of Bentek Solar.

MDSS Provides Customers with key benefits:

  • Reduced space requirements

  • Reduced material costs

  • Reduced labor costs

  • Safety and protection of photovoltaic investments

  • Complete isolation of the inverter fuses

MDSS Product Features include:

  • From three to eight integrated disconnects per MDSS

  • 600 or 1000 VDC disconnects

  • Multiple 100, 200 and 400 A disconnects in one MDSS

  • Enclosure is NEMA-3R + dust tight with removable bottom panels for wiring

  • Handles can be mounted internally or externally

“Our Multiple Disconnect Safety Systems are intended for installation next to the inverter. The MDSS provides customers with multiple UL 600 VDC or IEC 1000 VDC load-break disconnects combined in one safe, compact, easy-to-install enclosure,” said Jim Peplinski, Bentek Solar’s Chief Technology Officer.
