Product Details
125KW On-grid / Off-grid Type AC / DC Bidirectional Energy Storage
Converter
Product overview
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.
Product characteristics
- 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.
