1、How many MW's of Solar inverters have been supplied by your company in India and how does the future look like?
In 2015, Huawei signed a 100 MW contract with India Waaree, which is abreakthrough. In 2016, Huawei sees India an essential inverter market. Our goal is1.2 GW. According to forecast by Mercom Capital Group, the PV power capacity planned for India in 2016 will be increased to over 4 GW and the market scale will double. The PV market in India will maintain rapid growth. By 2022, PV power target yield will increase from 20 GW to 100 GW. Huawei will bring more advanced and useful products and solutions to the Indian market to contribute to the prosperity of the PV industry in India.
2、Please enlighten our readers on the unique technology aspect of these inverters installed in India and its performance.
High efficiency up to 99%. Multiple MPP trackers realize real time and accurate string detection. The detection accuracy can reach 0.5%, 6 times higher than traditional centralized inverters. Multiple MPP trackers can also effectively reduce the impact and influence caused by shadowing and string mismatch, dramatically improving the yields by at least 2% for ground PV plants, and up to 5% and more for hill and mountain mounted PV plants.
Fully closed design ensures high level protection based on our mature and advanced telecom technology. IP65 protection makes our inverter versatile for all the hostile outdoor environment like high temperature, high dampness, high altitude, extreme cold, sandy, salt and mist areas.
In addition, we remove quick wear parts like external fans with natural cooling technology and fuses, which enable ZERO touch maintenance and guarantee human and property safety.
We use our own chipset Hisilicon and operating system to reduce the weight and heat dispersion. There are no quick wear parts like fuse and external fans, which ensures free maintenance. Furthermore, our inverters are open, supporting inputs of different equipment and parts like trackers and sensors of other industries.
Furthermore, we adopt the Power Line Communication (PLC) technology, allowing communication via power cable and removing communications cable. The PLC is cable-free, and the communication bandwidth is much higher than RS485. Additionally, the engineering is accordingly simplified and economic.
Our patented anti-PID module can avoid PID effect without PV-tie to ground directly, effectively guaranteeing human safety.
Our string inverters are in excellent condition for the 100 MW project with Waaree. The stable and high efficiency running is highly recognized by the Waaree. We expect more customers to choose and enjoy the high performance of our smart PV inverters.
3、Please enlighten our readers on the debate of "Central vs. String Inverters Design" Which concept is best suited for India and why.
String is better. The string inverter design is not simply ideal for rooftops but also widely adopted by large-scale PV plants. The string inverter design has been highly recognized by the public. In addition, we have compared the two solutions from different aspects. The string inverter design has better performance in view of safety, yields, system cost, installation, O&M, monitoring, environmental adaptability, and grid connection. It is tested and proved not simply in theory but also in the practical application from customers' projects. Our string inverters and solution have been widely applied in a single project over 50 MW both in China and overseas markets.
India has tropical extreme climate with high temperature and dampness. There is also a long rainy season. Huawei fully closed design inverter with IP65 protection guarantees the long term operation with safety and reliability. Multiple MPP trackers enable high accuracy detection and improve the yields by over 3%. Our smart PV inverters become the brain of the plant, realizing smart operation and maintenance with digital information and internet technology.

The O&M efficiency can be increased by over 50% through our smart PV solution. We develop the advanced system for both plant and corporation levels, which can realize mobile and remote operation and maintenance globally.
6、What are the resources in terms of manpower for sales, O&M and other aspects developed and present in the Indian market?
We have over 20 persons as local team which includes the sales, products, and service. The team will be further expanded with the market and sales growth. More local employees will be added to the sales and technical team. Huawei is of shared technology, service and production. We have over 5700 staff in India with 2700 focusing on R&D. Also we have the relevant warehouse and spare part centers in India to best serve the market.
7、Please tell us about the unique technological features of your products which are also distinguishing factors.
Multiple MPP trackers and high accuracy string detection highly improve the yields and reduce the power loss. IP65 protection enables high environm ent adaptability and application. Open platform design enables cross industry cooperation.
Power Line Communication technology allows communication via power cable and removes communication cable. The PLC is cable-free, and the communication b a n d wi d t h i s m u c h h i g h e r than RS485. Additionally, the e ngine e ring i s ac cordi ngl y simplified and economic.
Anti-PID Module. Huawei anti-PID Module for Smart PV Plant is a solution to avoid PID effect without PV-tie to ground directly.
Natural Cooling Design. There are no external fans. The thermal conductive coefficient of gum fed inside the enclosure is 30 times higher than air.
