Solar PV inverter supplier Sungrow debuted its latest 1500V lithium iron phosphate (LFP) lithium-ion energy storage solution at trade show SNEC, held in Shanghai, China.
Sungrow said its range of products in the field allow for system capacities from 1MW to 6.9MW alongside LFP batteries rated at 1500V which can be assembled to produce an integrated system of up to 4.5MWh, which Sungrow said was suitable for both commercial and utility-scale installs.
The product is flexible for both DC- and AC-coupled designs and allows for the creation of all-in-one systems capable of providing services such as frequency regulation, peak shaving and other ancillary services.
Sungrow said the future of solar in a post-grid-parity era was for the technology to be “deeply integrated” with energy storage for grid stability.
“The integration of PV and energy storage relies on deep analysis and integration of the whole system instead of a mechanical combination of two systems,“ Jack Gu, senior VP at Sungrow, said.
Sungrow R&D director Dr Zhuang Cai spoke with Energy-Storage.news about what is required when it comes to building lithium-ion battery storage solutions at scale in the recent feature article, 'Building battery storage systems to meet changing market requirements'.
SNEC is widely considered the world's largest solar trade event, this year attendance from international visitors was limited by the coronavirus pandemic. Our sister site PV Tech was however able to send China-based editorial staff. Read about Carrie Xiao's visits to a number of mainstream module companies at the show to see their new products "all of which pointed to the fact that the industry has entered the 5.0 era of high-power modules (500W)".
This story first featured in a PV Tech Roundup of solar PV product launches taking place at the exhibition, which you can read here.
