125KW On-grid / Off-grid Type AC / DC Bidirectional Energy Storage Converter
125kW series on/off-grid type series energy storage converters are used for off-grid application scenarios such as peak cutting and valley filling, dynamic capacity increase, emergency power backup, mobile energy storage, etc.
With rapid capacity expansion, it is convenient to realize the parallel networking of multiple devices to form a small and medium-sized energy storage system;
Has a strong load adaptability, can be used independently off-grid;
Strong adaptability to the power grid, good availability;
Small size, space saving, single machine can form 0.5C energy storage system with 280Ah, 314Ah battery cluster, to achieve fine management of the battery.
- With DC side parallel capability, can be adapted to 500Ah+ larger capacity battery energy storage system;
- With off-grid multiple AC side parallel capability, suitable for isolated island micro grid scenarios;
- Dc side voltage range DC600~950V, the effective working voltage range increased by 16.6%, suitable for 280Ah+ lithium iron phosphate cell, can be combined with 260S and the following series of battery clusters to form a standard 0.5C energy storage battery system;
- Proprietary potting insulation protection technology is adopted to enhance the module's heat dissipation, salt spray corrosion resistance, dust resistance and shock absorption performance.
- Has a strong off-grid scene adaptability (nonlinear, impact, imbalance), with 200% super dynamic overload capability.
Application scenario
- Industrial and commercial energy storage (Peak cutting and Valley filling)
- Isolated island micro grid
- Photovoltaic energy storage and charging scenario
- Mobile energy storage
