Enphase Energy Microinverters Comply with New Rule 21 Requirements
FREMONT, Calif., Feb. 19, 2019 (GLOBE NEWSWIRE) -- (NASDAQ:ENPH), a global energy technology company and the world’s leading supplier of solar microinverters, today announced its microinverters’ compliance with California Rule 21 requirements by the February 22, 2019, regulatory deadline. Leading California installers continue to choose Enphase Energy microinverters for their timely compliance with California regulatory requirements, enabled through over-the-air software updates of always connected Enphase systems.
In September 2017, California’s Investor-Owned Utilities (IOUs) updated Electric Rule 21, which requires advanced grid functionality (AGF) for smart inverters. Enphase microinverters achieve compliance with Electric Rule 21 through the application of a Rule 21-compatible grid profile to certified hardware. All Enphase S- and IQ™ series microinverters are certified for new Rule 21 changes with the addition of the Frequency Watt (Function Five) and Volt Var (Function Six) functions. A new Rule 21-compliant grid profile for Enphase microinverters will be available on February 22, 2019. Enphase installers can apply this grid profile before, during or after installation using the Enphase Installer Toolkit™ app on-site, or remotely, through the activation screen in Enphase Enlighten Manager™ on systems outfitted with communications technology that keeps them always connected.
“We choose Enphase because software-defined microinverters that are always connected to data networks are ideally suited to making compliance with regulations like Rule 21 painless,” said James Allen, co-founder of Allterra Solar. "Enphase also makes providing proof of compliance during the interconnection process very simple, which can allow our customers to benefit from their solar systems sooner. For us, faster turn-around times for the Permission to Operate (PTO) means concluding the business transactions with customers sooner, which is another benefit Enphase microinverters deliver.”
“In California, Rule 21 is all about safety and stability of the electric grid, and solar installation companies have to ensure the systems they install are in compliance with this requirement if they hope to get approval to turn the solar systems on,” said Oz Wardak, director of operations at California Solar Systems. "We have been working with Enphase microinverters since 2010 and started using them almost exclusively as of 2013 because the Enphase team has always been one step ahead with compliance. This is just one way in which Enphase makes it easier for us to focus on providing outstanding customer service. Our customers quickly become fans of Enphase too, because of the microinverters’ increased production over string inverters, system flexibility, production transparency through monitoring, safety, reliability, and great warranty.”
“Reliable, service-focused solar installers like Allterra Solar and California Solar Systems are the kinds of companies that drive our success in the California market,” said Raghu Belur, co-founder and chief products officer at Enphase Energy. "We are proud to see our customers use the advanced features we designed into our products to accelerate their businesses, bring safer and more affordable solar to their customers, and leverage the advanced compliance management, data communications, and safety features of our microinverters to stay on the cutting edge of compliance.”
The California Public Utilities Commission’s (CPUC) Rule 21, Phase 2 requirements for solar generating facilities utilizing inverter–based technologies will become mandatory for systems for which an interconnection request is submitted on or after February 22, 2019. Solar installers can update their Enphase microinverter-based systems with grid profile “CA Rule21 201902 VV VW FW” as of February 22, 2019.
