Technical Parameter Characteristics
Three-Phase Four-Wire Design and Load-Carrying Capability
The three-phase four-wire design enables single-phase and three-phase active and reactive power control. Meanwhile, the four-leg product has pure single-phase load-carrying capability. This design feature makes the product more flexible and diverse in power control, meeting the control needs of different types of loads. Whether for single-phase or three-phase loads, precise power control can be achieved.
Installation Flexibility
It is compatible with both drawer-type and side-mounted installation. Users can choose between front-wiring and rear-wiring options, making the installation methods more flexible. This design takes into account different installation environments and user needs. Whether in space-constrained scenarios or situations with specific wiring requirements, appropriate installation solutions can be found, enhancing the product’s applicability.
Parallel Operation Capability
On the AC side, it allows up to 20 units to be directly connected in parallel (in grid-connected mode). This powerful parallel operation capability means that larger power demands can be met by connecting multiple devices in parallel. It is suitable for scenarios with high power requirements such as industrial and commercial energy storage and microgrids, facilitating system expansion according to users’ actual needs.
Three-Phase Unbalanced Load-Carrying Capability
It has a 100% three-phase unbalanced load-carrying capability, perfectly adapting to conditions in distribution substations, industrial and commercial settings, and microgrids. In actual power systems, three-phase unbalance is relatively common. This product can fully adapt to such working conditions, ensuring stable operation under unbalanced three-phase loads and providing reliable power support for various scenarios.
Grid-Connected/Off-Grid Switching Function
It supports seamless switching between grid-connected and off-grid modes, with a switching time of less than 20ms. This rapid switching capability ensures quick response in case of grid failures or when off-grid operation is required, safeguarding continuous power supply to loads, reducing the impact of power outages on users, and improving power supply reliability and stability.
Functional Configuration
It is equipped with PQ, VF, VSG, and black-start functions. These rich functions enable the product to meet diverse needs in different application scenarios. For example, in microgrids, it can achieve power quality control (PQ), voltage and frequency regulation (VF), virtual synchronous generator (VSG) functions, and realize black-start in emergencies to quickly restore power supply.
Detailed Interpretation of 50kW Modular Converter Technical Parameters
As a key device in energy storage systems, the 50kW modular converter’s technical parameters directly affect system performance and applicability. The following is a detailed interpretation of its important technical parameters.
Electrical Parameters
DC Voltage Range
The DC voltage range is 600 – 950V (full-load: 630 – 900V). This wide DC voltage input design allows the converter to adapt to various energy storage batteries with different specifications, meeting the voltage requirements of different battery systems and improving device versatility and compatibility.
DC Side Maximum Current
The DC side maximum current reaches 192A. This large current-carrying capacity ensures stable operation of the converter during high-power output, effectively meeting the high-current demands in industrial and commercial energy storage scenarios and ensuring efficient energy transmission.
Allowable AC Voltage Range
The allowable AC voltage range is 400V (-20% – +15%). This parameter indicates that the converter can adapt to AC voltage inputs with certain fluctuations, enhancing the device’s adaptability in complex grid environments and ensuring system stable operation.
Environmental Parameters
Operating Temperature
The operating temperature range is -20 – 55°C (derating above 45°C). The converter can operate within a relatively wide temperature range, functioning normally in both cold northern regions and hot southern regions. When the temperature exceeds 45°C, the device will automatically derate to protect itself from high-temperature damage and extend its service life.
Protection Grade
The protection grade is IP20. This protection grade effectively prevents solid foreign objects with a diameter greater than 12mm from entering the device, ensuring stable operation in relatively clean indoor environments.
Altitude
The applicable altitude range is below 3000m (derating above 2000m). In high-altitude areas, the air is thin and heat dissipation conditions deteriorate. The device operates in a derated mode to ensure its performance and reliability, adapting to usage needs in different altitude areas.
Performance Parameters
Noise
The noise level is ≤75dB. This low-noise design prevents excessive noise interference during device operation, making it suitable for environments with strict noise requirements, such as energy storage projects near residential areas.
Maximum Conversion Efficiency
The maximum conversion efficiency is ≥98%. High conversion efficiency means that during energy conversion, the converter can convert more DC electrical energy into AC electrical energy, reducing energy loss, improving the energy utilization efficiency of the entire energy storage system, and lowering operating costs.
Weight and Dimensions
The weight is 70kg, and the dimensions (width * depth * height) are 480659(720)260mm. Reasonable weight and dimension design facilitate device installation and transportation, and also make it convenient for deployment in limited spaces such as cabinets.
Structural Parameters
Structural Wiring
For structural wiring, the 14-type wiring method is primary and secondary at the front, with rear air intake and front air outlet. The 24-type wiring method is primary and secondary at the rear, with front air intake and rear air outlet. Different wiring and ventilation designs meet the needs of different installation scenarios and heat dissipation requirements, ensuring stable device performance during operation.
This 50kW modular converter, with its comprehensive and excellent technical parameters, delivers outstanding performance in various application scenarios such as industrial and commercial energy storage, distribution substation energy storage, and optical storage microgrids, providing strong support for the efficient and stable operation of energy storage systems.
