Home – Project Detail
The modular energy storage converter is constructed using V2G high-frequency isolation modules, combining the advantages of both high-frequency isolation and modularity. The cabinet is compatible with IBG75027 and IBG30050 modules, allowing flexible configuration into energy storage converters of different power levels and battery voltages according to specific requirements.
When paired with an STS (Static Transfer Switch), seamless switching between grid-connected and off-grid modes can be achieved, ensuring uninterrupted power supply to loads. This grid-connected/off-grid energy storage converter is widely applied in medium-power scenarios such as microgrids, areas with frequent power outages or weak grids, and user-side energy storage.
High-frequency isolation between the battery and the grid eliminates the need for a line-frequency transformer, resulting in higher efficiency through high-frequency isolation technology, reaching up to over 95%.
Compared to traditional modular energy storage, high-frequency isolation eliminates the need for a line-frequency isolation transformer and indirect costs (such as cabinets and fans), reducing system costs.
As a modular energy storage converter, this product is highly suitable for repurposing retired or old power batteries for energy storage. With a power range covering 15kW~200kW, it is ideal for energy storage in industrial and commercial parks. The flexible embedded PCS solution provides core PCS modules, facilitating system integrators in flexibly designing various forms of energy storage systems. The isolated bidirectional AC/DC converter offers higher safety, efficiency, and a smaller size after connecting to batteries. When paired with an STS module, it can switch to off-grid power supply after a grid outage, making it suitable for microgrid scenarios (such as islands and remote villages). Its wide voltage range makes it highly suitable for the echelon application of retired power batteries. It can also be configured as mobile energy storage, suitable for important !
