SMA’s residential and commercial inverter solutions now comply with the Hawaiian Electric Company’s (HECO) new guidelines for grid interaction. The Sunny Boy TL-US with Secure Power Supply and Sunny Tripower TL-US inverter lines meet interim frequency and voltage ride-through (FVRT) and new ultra-fast transient over-voltage (TrOV2) requirements. They are now included on HECO’s qualified equipment list for these specifications.
Both of SMA’s most popular inverter lines have been tested to and found to meet TrOV2 requirements. Interim ride-through compliance is achieved with a simple adjustment of parameters via SMA’s Sunny Explorer free software or through the SMA Cluster Controller during installation and commissioning. Later this year, SMA will release a firmware update to meet full ride-through settings.
“SMA is committed to Hawaii and its goals of renewable energy integration and grid stability,” said Henry Dziuba, president and general manager of SMA America. “We are proud to offer the Hawaiian market the world’s most advanced residential and commercial inverters, which now satisfy all of the state’s new and existing grid requirements.”
The Sunny Boy TL-US series—available in seven models from 3,000 to 7,700 watts—is equipped with Secure Power Supply functionality, which provides up to 1,500 W of daytime standby power when the grid is down for charging laptops, cell phones and more, without the need of additional, costly batteries. Its transformerless design ensures high efficiency and reduced weight, while its integrated DC AFCI functionality meets NEC arc-fault protection requirements and is certified to the UL 1699B standard. It also provides easy monitoring and control features, including a large graphic display and the optional plug-and-play Webconnect data module for easy system monitoring with direct data transmission to Sunny Portal.
With leading CEC efficiencies, a wide input voltage and extended operating temperature ranges from -40 to 140 F, the Sunny Boy TL-US with Secure Power Supply offers maximum power production under a variety of conditions. The inverter’s shade-tolerant OptiTrac™ Global Peak MPP tracking algorithm and two MPP trackers provide increased energy production for complex arrays with partial shading or multiple roof orientations.
The Sunny Tripower TL-US is UL listed for up to 1,000 V DC maximum system voltage and has a peak efficiency above 98 percent. Available in 12, 15, 20 and 24 kilowatt models and also including OptiTrac Global Peak, the Sunny Tripower TL-US delivers full grid management functionality, cutting-edge communications and advanced monitoring. It is also equipped with all-pole ground fault protection and integrated AFCI for a safe, reliable solution. The Sunny Tripower TL-US offers unmatched flexibility with a wide input voltage range and two independent MPP trackers. Suitable for both 600 V DC and 1,000 V DC applications, it allows for flexible design and a lower levelized cost of energy.
