Ginlong Technologies ginlong solis inverterannounced that the complete product line of Ginlong Solis (NA) Single-Phase 4G PV string inverters have been tested and certified for compliance to the new UL 1741 SA Standard as described in the California Public Utility Commission (CPUC) Rule 21.  Ginlong Solis (NA) 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 starting in September 2017.  See the entire list of qualified inverters at  Go to, Equipment / Inverters, and click on the list.

Each Ginlong Solis (NA) single-phase 4G PV string inverter 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 (DG) into their transmission and distribution systems.  This is a very exciting time for the solar energy industry as we see more solar DG’s contributing larger and larger percentages of the country’s electricity demand.

The Ginlong Solis (NA) single-phase 4G PV string inverters are still anti-islanding inverters, however the UL 1741 SA certification will allow an inverter to interact with the grid before complete disconnection.  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 these inverters to adapt their output, promoting grid stability and resilience.
