APsystems announced that the new Chint three-phase 25-kilowatt 208 VAC inverter is now included in Sunspec's Photovoltaic Rapid Shutdown System (PVRSS) certification and meets the UL 1741 standard. This brings the total number of CHINT inverter models that have been tested by CSA and certified for use with APsmart's PVRSS solution to five.
Five other unique inverter brands joined CHINT, which have been added to the APsmart PVRSS certification compatibility list, including Delta, Fronius, SolaX, Solis and Solectria. More inverter manufacturers and models will continue to be tested and added to the growing list of inverters compatible with APsmart PVRSS.
The new 25 kW Chint three-phase string inverter is specially designed for rooftop and carport photovoltaic applications. This compact device is a high-performance, advanced and reliable inverter designed for the North American environment and power grids. The product comes with a quick shutdown junction box, which is fully integrated and can be separated from touch safety fuses, monitoring, and AC and DC disconnect switches. When used with APsmart RSD products, the integrated PLC transmitter in the quick shutdown junction box can achieve PVRSS-certified module-level quick shutdown.
The compatibility of these inverters with APsmart's Rapid Shutdown System (PVRSS) enables APsmart to provide more reliable, flexible, safe and cost-effective solutions for residential and commercial systems. APsmart PVRSS has passed CSA certification, meets UL 1741 electrical safety standards, and fully complies with the National Electrical Code (NEC) 2014, 2017 and 2020 690.12 fast shutdown requirements.

"APsmart PVRSS has passed CSA certification, meets UL 1741 electrical safety standards, and fully complies with the National Electrical Code (NEC) 2014, 2017 and 2020 690.12 fast shutdown requirements."
Yes, 2020 690.12 seems to be different from 2017 RSD requirements. Now a PLC link from the inverter to the roof-mounted RSD device is required. The market is likely to resolve this "extra" closure requirement. Companies such as SolarEdge and Enphase can integrate RSD and PLC into converters or micro-inverter modules as part of the system. Adders in the name of safety began to dilute the value to increase the cost and complexity of solar photovoltaic systems. Therefore, it is still unclear whether TESLA solar photovoltaic roof tiles have built-in RSD and PLC functions in each tile nailed to the roof? Unless there is tile 4.0 with built-in RSD, the roof tile option does not comply with 2020 690.12.
