What recent innovations in solar inverter technology is Sungrow excited about for the Indian market?

Since its inception, Sungrow has been the forerunner implementing new technologies.

As the versatility of wide band gap devices is gaining acceptance across power electronic devices, Sungrow has implemented the use of Si-C devices in the inverters to offer features like higher power density, better thermal characteristics and higher efficiency.

As Fixed Dispatchable RE power tenders are becoming prevalent, we are coming up with AC and DC coupled BESS solutions.

Sungrow inverters are certified to operate in weak grid, which aids the process of RE adoption in the far-flung areas with limited access to quality grid.

We have added a combination of hardware and AI based approaches towards diagnosis and protection as an additional safety layer.

Sungrow has also incorporated design improvements to ease the O&M for both string and central inverters.

How does Sungrow adapt its solar inverters to the unique climatic and grid conditions in India?

The Summer season this year has been particularly harsh on the Indian geography. This includes high ambient temperatures exceeding 50°C and a consistent and sustained increase in the peak electricity demand, which put additional stress on the Indian grid.

Sungrow’s utility scale inverters come with nameplate power ratings at 51°C. This allows for inverters to maintain the rated power capability at higher ambient conditions and support the grid dispatch efficiently.

Sungrow Inverters with DC coupling allow to provide output power during different times of the day, easing the load on grid while saving on the AC side BoS.

Sungrow inverters adapt well to different grid conditions which allows for connecting inverters in different locations.

What technical challenges does Sungrow face in the Indian solar market, and what solutions have been implemented?

As the population of Inverter Based resources increases, the inverters are required to support the grid in terms of power quality and other dynamic supports. Sungrow is continuously improving its inverters to cater to these requirements.

Adoption of higher Watt-peak solar modules has picked up pace. Sungrow has released new generation inverters to suit the new requirements.

Sungrow has made many protection features like AFCI, Type I+II SPD as a standard in C&I inverters to install solar plants on critical infrastructure.

How is Sungrow integrating solar inverters with energy storage to improve efficiency and reliability in India?

Sungrow has devised strategies towards energy storage integration with Solar PV plants.

Sungrow has developed PCS in lines of the existing utility scale Central inverters (1+X series) to share the spares inventory up to 90% of common components.

Sungrow Central inverters can support DC coupled BESS, which results in higher round trip efficiency while increasing the PV plant capacity utilization.

What are Sungrow’s long-term goals for the Indian market, and how do you see solar inverters evolving over the next decade?

Sungrow is very optimistic about the growth of the Indian RE market. It is our endeavor to keep innovating and provide the best power conversion equipment to India in line with India’s targets to reduce carbon emissions.

In the coming decade, with the growth of electricity demand, we may see a trend towards de-centralization of the grid. The solar inverters are poised to gain features like grid forming capabilities, higher DC input voltages, smart grid adaptation, direct MV integration, etc.
