FREMONT, Calif., Feb. 19, 2019 (GLOBE NEWSWIRE) -- Enphase Energy, Inc. (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. More information on Enphase microinverter compliance with Rule 21 can be found here: https://enphase.com/en-us/ca-rule-21.
