Seattle-based APsystems this week at Solar Power International is debuting its new microinverter with Rule 21 grid support functionality.
The company said that its YC600 microinverter was designed to meet the latest grid compliance standards, including UL 1741 SA requirements for California Rule 21, which came into effect last week.
California Rule 21 relates to interconnection agreements between homeowners and utilities for new solar energy systems that transmit electricity to the grid. As of Sept. 8, California’s investor-owned utilities are requiring updated functionality from the inverters connecting to the grid.
APsystems also said that the unit offers 300VA peak output power per channel and works with 60- and 72-cell PV modules with dual, independent maximum power
