Innovative Solar Inc.’s Rapid Shutdown with Cap Discharge product differentiators. 1. Innovative Solar Inc. offers Capacitor Discharge on every 600v string, while most 3rd party manufacturers do not offer the function. At the same time, most string inverters sold today do not discharge their bulk capacitors fast enough to meet the new NEC690.12 code. In order for systems to be code compliant, equipment in addition to a roof mounted SOB (Shut Off Box) is likely to be needed. 2. Operation is Automatic. No separate action is required because the system is immediately triggered when the fire department cuts grid power. Innovative Solar Inc. does offer an optional E-stop, however, in case the local jurisdiction requires it. 3. Innovative Solar Inc.’s Rapid Shutdown system uses a Fail-safe hardwired design. Isolation is virtually guaranteed without the need for redundancy, maintenance, or periodic testing. Systems using shut trip technology or digital communication require positive feedback in order for the fire department to verify that the PV panels were isolated, because operation is not guaranteed. 4. No maintenance is required with the system from Innovative Solar Inc. There are no batteries to be maintained or replaced, and no PV wires to torque. 5. The Innovative Solar Inc. system allows for operation on nearly any low voltage AC or DC source, providing Flexibility in implementation. The simplest low cost method is to simply power it from a Class 2 bell transformer installed in a convenient location. The presence of grid power controls operation. 6. The Innovative Solar Inc. system allows for a Ground level reset. Shut trip systems can normally be reset only by going on the roof. 7. The system from Innovative Solar Inc. is rated for Extreme temperatures: -40°C to 70°C (-40°F to 158°F). Most Rapid Shutdown systems are limited to -25C or higher. 8. Innovative Solar Inc. offers a Full range of product, including 1000v and up to 8 channels per box. Many manufacturers have more limited offerings. 9. The Rapid Shutdown system from Innovative Solar Inc. provides all Screw less PV connections in order to maximize reliability and ease of installation and no torquing is required. 10. No special tools or cabling is required to install the Rapid Shutdown system from Innovative Solar Inc. Control power can be routed with standard THHN wire through the PV conduit. 11. Innovative Solar Inc.is the only Rapid Shutdown system available today in the popular SolaDeck enclosure.

12. No roof mounted fuses. PV fuses are required on all installations where the number of strings exceeds 2 per MPPT. Unlike combiner type solutions, the Rapid Shutdown system from Innovative Solar Inc. will support any number of isolated strings allowing fuses to be mounted at ground level.
