Ginlong Technologies announced that the complete product line of Ginlong Solis (NA) single-phase 4G PV string inverters has been tested and certified for compliance to the new UL 1741 SA standard as described in the California Public Utilities Commission (CPUC) Rule 21.
The company says the Solis single-phase 4G PV string inverters, ranging from 2.5 kW to 10 kW, can be purchased today with the UL 1741 SA certification. These inverters meet Rule 21 requirements for installations that started in September.
Ginlong says each of the Solis single-phase 4G PV string inverters will be labeled “Grid Support Utility Interactive Inverter” (per Rule 21 guidance) and will introduce new smart inverter features to PV system owners, as well as demonstrate new grid-interactive functionalities that will better enable utilities to integrate more distributed generators into their transmission and distribution systems.
Ginlong notes the Solis single-phase 4G PV string inverters are still anti-islanding; however, the UL 1741 SA certification will allow an inverter to interact with the grid before complete disconnection. According to the company, these new Solis inverters will offer remote powering and curtailment, low- and high-voltage and frequency ride through, power factor control, power ramp-up, frequency-watt and voltage-watt control, and other utility-interactive capabilities that allow the inverters to adapt their output, promoting grid stability and resilience.
