What applications or markets is the 95KTL suited for?
The Huawei 95KTL is the largest string inverter currently from Huawei, but it is not simply just “a larger string inverter from Huawei”. It is a breakthrough that delivers provably superior economics to the utility-scale market compared to any alternative in the market – central or string.
The power density that Huawei 95KTL has achieved without the use of external fan cooling is a world record and is the result of the company’s sustained and intense focus on power electronics research and development. The Huawei 95KTL is the only string inverter in its power class to utilize natural cooling technology instead of external fans, delivering lowest cost of ownership through reduced O&M expenses.
Why is this solution more beneficial to the developer and EPC than a central inverter?
The Huawei 95KTL string inverter supports Smart O&M and is safe and reliable with maximum efficiency:
We made it smart with:
-6 MPPTs for versatile adaptions to different layouts
-12 strings intelligent monitoring and fast trouble-shooting
-Power Line Communication (PLC) supported
-Smart I-V Curve Diagnosis supported
It is efficient with:
-Maximum efficiency of 99.0%
-CEC efficiency of 98.5%
-800V output voltage and decrease 75% AC wire loss versus 400V
It is safe with:
-DC AFCI compliant to UL 1699B Type I
-Type II surge arresters for both DC and AC
-Residual Current Monitoring Unit (RCMU) integrated inside
And it is reliable with:
-Natural cooling technology
-Fuse free design
-Protection rating of NEMA Type 4X
How does Huawei test its inverters?
Huawei tests its inverters in a specialized R&D testing center that very few large companies could attempt to create in house. Multiple extreme environment tests mimicking -40 degrees Celsius, high altitude, hot, sandy environments and lightning strikes are performed. For example, we actively seek to trigger lightning by launching a rocket into a lightning storm with a gold wire that goes down into the inverter. We can then study the effects and engineer inverters to withstand them.
What are some highlights of the last year for Huawei?
This last year has been remarkable for Huawei. IHS Markit and GTM both listed us as Number 1 for global shipments in 2016 and we made breakthroughs in U.S. solar market with the support from our partners and customers.
Where does Huawei see the U.S. solar market going?
Huawei continues to grow and invest in our presence and market share in the United States. The world’s most popular inverter is now shipping in volume in the US and from our regional headquarters in the heart of Silicon Valley and across the country. Our team of nearly 50 professionals is ready to support projects from DG to mega-scale projects well above 100MW across the United States.
Huawei will continue to serve the US market with our 15 R&D institutions and centers globally, chipset design in Santa Clara, CA, inverter topology & algorithm in Stockholm, Sweden, inverter architecture & design in Nuremberg, Germany to our manufacturing in Shenzhen, China.
Huawei is the global leader for inverters in 170+ countries with over 134+ logistics centers. We are #72 in Interbrand’s Top 100 Best Global Brands and #83 in Fortune’s Global 500. Huawei has shipped more MW than any other central, string or micro-inverter supplier. We will continue to grow in the US market and globally because innovation is pivotal at Huawei with 14.6% of revenue was invested back into R&D into 2016.
