UL, a global safety science organization, has issued its first UL 9540 certification for a complete home energy storage system (ESS) to Enphase Energy, a solar inverter solution developer. The UL 9540 certification certifies that Enphase Energy’s ESS products is capable of storing renewable energies while ensuring safety and effectiveness.
UL’s firs certification for residential ESS, UL 9540, was issued to Enphase Energy in early November. Residential and commercial customers can use certificated ESSs to store electricity generated from solar, wind and other generating facilities onsite for power consumption. The ESSs can further optimize renewable energy consumption efficiency, lower utility demand, and offer energy when under power outage.
“Enphase is excited that our ground breaking AC Battery product is the first residential energy storage product to receive a UL 9540 certification for the North American market,” said John Berdner, VP of Regulatory and Policy Strategy at Enphase Energy. “Our work with UL has allowed us to quickly migrate our storage technology from Australia to North America, while complying with all applicable North America safety standards.”
A UL 9540-certified system
An ESS certified to UL 9540 is comprised of a UL 1973-certified stationary battery pack used in conjunction with a UL 1741-certified inverter. Achieving certification to both individual UL product standards is essential for completion of the UL 9540 system certification
As more and more ESS are installed, consumers, utilities, commercial building owners, insurers, fire fighters and electrical/building inspectors will all benefit from these systems meeting UL 9540 system safety standard requirements.
Enphase’s AC Battery is comprised of a stationary battery pack manufactured by Eliiy Power Co., Ltd, a Japanese corporation that is UL 1973 certified and an UL 1741 certified inverter manufactured by Enphase. It also meets the latest National Electric Code 2017 requirement for Listed equipment in the newly published Article 706, Energy Storage Systems.
