Yaskawa – Solectria Solar, a commercial PV inverter manufacturer in the U.S., has announced that its PVI 50 TL and PVI 60 TL inverters are now fully compliant with California Public Utility Commission Rule 21 – UL 1741 SA.
According to the manufacturer, the company achieved compliance two months prior to the deadline.
“We are committed to providing grid-support-enabled utility-interactive inverters to meet our nation’s needs to ensure a stable grid,” says Miles Russell, director of product management. “Yaskawa – Solectria Solar is continuously working to lead the market with the highest quality and reliability while keeping up with the latest requirements.”
Rule 21 describes newly defined needs by utilities for grid stabilization as PV generation in California continues to grow. The rule describes interconnection, operating and metering requirements for inverters to allow the grid to accept increased capacity as California adds more gigawatts to its grid. As reported, Rule 21 will allow inverters to actively interact with the grid and contribute to system-wide stability and reliability.
UL 1741 SA prescribes testing methods to qualify smart inverters for compliance with Rule 21.
