Ideal Power’s next-generation SunDial and Stabiliti series power conversion products have met all the safety, performance, reliability and grid support requirements for UL 1741 Supplement A (SA) certification. With this certification, Ideal Power’s products meet the newest standards for supporting grid modernization, now required by the California Public Utilities Commission (CPUC) as an amendment to the Rule 21 tariff.
To achieve UL 1741 SA certification, solar inverters must remain online and automatically adapt their power output in real-time to stabilize the electric grid during periods of abnormal operation such as heat waves or brownouts. Under traditional utility interconnection requirements, inverters simply disconnect when the grid experiences stability issues. However, inverters with UL 1741 SA certification can provide reactive power – an essential component for balancing power delivery and stabilizing the grid.
“By achieving the UL 1741 SA certification, Ideal Power is meeting a higher standard for advancing grid modernization with a product line that is adaptable for shifting market parameters in California and beyond,” said Ideal Power CEO Dan Brdar. “We anticipate more states will adopt similar requirements and we believe Ideal Power products will support higher integration rates of distributed energy resources to the grid.”
UL 1741 SA-listed products are essential for supporting a reliable energy system, particularly in regions with high rates of renewables such as California where nearly 14 percent of electricity comes from solar. Other states with high solar penetration and distributed generation are requiring or expected to require UL 1741 SA or similar regulations to optimize the oncoming megawatts of grid-tied solar and energy storage.
Ideal Power’s SunDial and Stabiliti series power conversion products are compatible with leading battery technologies, providing peak demand management and offering applications for alternating current (AC) microgrids, direct current (DC) microgrids and backup power. Ideal Power’s grid-resilient, bi-directional and multiport technologies are cost-effective, versatile and scalable solutions that enable the integration of solar-plus-storage.
