[February 21, Shenzhen, China] Huawei’s Smart String-level
Disconnection (SSLD) tech for PV plant safety gained certificate of
low-voltage circuit breaker (IEC60947-2) from DEKRA and Intertek
respectively, which is the 1st vendor to get the
certificates by using the innovative smart string shutdown tech. The
SSLD tech can accurately identify faults from DC side of PV system
such as reverse polarity connection, backflow current, short
circuit, and implement automatic string-level shutdown on
millisecond basis, which can effectively improve the active safety
capability of the PV plant.
With the penetration rate of solar power increasing, the safety
issues of PV system can't be ignored, among which over 70% are from
DC side according to the statistics of Huawei. Due to the
characteristics of PV Huawei integrate digital technologies with
power electronics, and launched the world's first PV inverter that
supports smart string disconnection, which can accurately detect the
current signals of each string. When a fault is detected, the
software transmit the switch-off signal to the DC switch,
immediately trigger disconnection and alarm, which can reduce the
fire risk of PV plant significantly.
Dr. Kilian Avilés, SVP of DEKRA Asia Pacific and Managing Director
of Mainland China and Hong Kong, stated: “I am very excited to see
Huawei's cutting-edge solution that integrates digital and smart
technology with electronics to guard safety and maximize energy
efficiency. We look forward to working with Huawei to create a green
and sustainable future.”
Li Qiong, General Manager of Intertek Electronic & Electrical in
South China, said, "Intertek and Huawei Digital Power have
maintained close cooperation in the field of product compliance for
a long time and have achieved fruitful results. As a trusted quality
partner in the energy field, Intertek advocates building and
highlighting the quality advantages in new products and new
technologies with professional and innovative comprehensive
services. In the future, we hope to deepen our cooperation with
Huawei Digital Power and explore a new level of green and
intelligent product security. Together, we will contribute to the
healthy and sustainable development of the energy industry."
Steve Zheng, president of Utility Smart PV Business of Huawei said,
"It is imperative to enhance the safety protection level of new
energy plant by digital technology. The two organizations certified
the innovation and reliability of Huawei's Smart String-level
Disconnection technology, which ensures safe operation of the PV
plant based on the design concept of all-scenario, high-precision
and fast-response. The wide application of this technology will
escort PV to become the main energy source. In the future, Huawei
will continue to deepen the innovation and integration of digital
and energy technologies, and work with global partners to improve
energy security assurance capabilities and accelerate global energy
transformation."
