Bentek Solar Introduces PV 101 MDSS for Safety and Code Compliance
Bentek Solar announces that its MDSS is a cost-effective means for providing safety and code compliance for PV installations. The MDSS contains a bank of load-break disconnects in a compact, free-standing cabinet. Typically, the MDSS is installed next to the inverter and provides the safety and arc flash reduction that is needed in all photovoltaic systems, solving a critical safety issue that is commonly overlooked. The MDSS provides code-compliant fuse isolation that inverters do not. This allows fuses in the inverter to be removed safely.Mult
Bentek Solar’s MDSS with optional zone current monitoring is optimized to work with most inverters at both 600 and 1000VDC. The number of inputs and ampacity of the load-break disconnects in the MDSS are matched to the number and ampacity of the internal inverter fuses. This ensures that when the MDSS arrives at the project site, it is simple to install by eliminating extra racking, conduit and expensive labor that is required with traditional individual knife blade disconnects, saving up to 30 percent in total cost. The installer typically runs the cables up through the bottom of the MDSS and connects one cable to each input and one cable to each output. Each output cable then runs to an inverter fuse. For example, if the inverter has eight internal fuses that are 400A each, the MDSS would contain eight 400A load-break disconnects, with each disconnect connecting to an inverter fuse.
