POWER INTEGRATION & GRID CONNECTION EXPERTS: FROM PV-
ESS-CHARGING TO DIGITAL DISTRIBUTION NETWORKS

We integrate Chinese and American standards, providing power integration and grid connection services at 35kV/110kV voltage levels for business parks, highway service areas, industrial plants, and the power grid side. Compliant, efficient, and locally delivered, we have helped clients maximize renewable energy grid connection efficiency, reducing grid connection modification costs by an average of 30%.

Integrated Solar Storage and Charging Solution

Full chain integration

·Covers the entire chain of photovoltaics, energy storage, and intelligent charging, connecting the flow of energy, information, and value.

Scene adaptation

·Commercial parks, highway service areas, industrial and commercial energy storage, microgrids.

Core values

·Compatible with US domestic photovoltaic module standards (UL1703), no secondary design changes required. ·Compliant to enjoy IRA tax credits - core equipment meets domestic procurement ratio requirements, UL1741 certification complete. ·Reduce grid connection renovation costs — through standardized interface design and pre-coordination, change orders are reduced by 70%.
