IMO worked closely with Fimer to achieve this listing because it required the development of an additional capacitance vent circuit to divert the stored current when the fast shutdown began. This product has also been certified by UL as a Photovoltaic Rapid Shutdown Equipment (PVRSE) component for use in the required categories. These new offerings complement IMO’s current UR-listed FireRaptor offering for NEC 2017 and NEC 2020 compliance, thus providing a complete agnostic solution for all inverters on the market.
IMO FireRaptor Receives UL PVRSS List of FIMER Inverters
IMO is very pleased to announce that it has launched its latest UL PVRSS (Photovoltaic Rapid Shutdown System) listing for the Fimer UNO range of 1.2kW to 6.0kW solar inverters as well as the Fimer PVS range of solar inverters from 50 kW to 60 kW according to UL1741 guidelines.
IMO worked closely with Fimer to achieve this listing as it required the development of an additional capacitance bleed circuit to dissipate the stored current when the fast shutdown began. This product has also been certified by UL as a Photovoltaic Rapid Shutdown Equipment (PVRSE) component for use in the required categories. These new offerings complement IMO’s current UR-listed FireRaptor offering for NEC 2017 and NEC 2020 compliance, thus providing a complete agnostic solution for all inverters on the market.
Joe Covington, general manager of IMO Automation of Cumming, GA, said, “The support of the efforts and inverter manufacturers in the marketplace is key to the continued growth of the industry in the face of NEC’s evolving regulatory requirements. It is these partnerships and convenience They got in touch with IMO for a safe and reliable rapid shutdown solution that sets us apart from the competition. ”
In addition to the PVRSS listing of the solar inverters of the Fimer UNO and PVS family, IMO is extremely pleased to announce that the FireRaptor is the first product for fast shutdown at module level NEC2017 and NEC2020 to be listed under PVRSS on the new AFCI -Compatibility requirements tested by UL. AFCI interference has long been a problem in the solar industry as the use of MLPE devices, power line communications, or other similar technologies becomes more common. With this in mind, UL began developing AFCI test requirements for PVRSS-certified rapid shutdown components. IMO was the first company to present and receive certification in accordance with these new requirements as part of its PVRSS certification with the Fimer UNO & PVS inverter series.
Joe Covington commented, “This new development allows us to provide potential consumers with confidence in selecting the IMO FireRaptor for a potential installation. Whichever inverter or charge controller is selected, the FireRaptor is truly an agnostic.”
The FireRaptor is designed for installation at the solar module level and offers a safe shutdown of the DC power supply to ZERO volts in an emergency. Shutdown is initiated in three ways: manual operation via an emergency stop button (which can be conveniently located at floor level for easy access), interruption of the AC power supply, or a temperature rise trigger.
The FireRaptor works like a circuit breaker, making the FireRaptor compatible with all string inverters and not affecting their operation or performance in any way. In addition, the FireRaptor was developed for fail-safe operation in order to ensure that subsequent damage to the FireRaptor (e.g. by fire) does not affect the insulation and the shutdown status of the solar module. In fact, the FireRaptor has been tested for destruction by TÜV in Germany, with full zero-volt isolation maintained throughout the testing process.
