Energy Storage Converter & Booster integrates PCS, dry-type transformer

Product Description

This Energy Storage Converter & Booster Integrated Unit,, is a high-integration energy management device designed for green energy systems such as solar and wind power. Its core function is to temporarily store electricity generated from solar/wind energy in battery systems; when needed, the stored energy is inverted by the Energy Storage Converter (PCS) and transmitted to a three-phase AC step-up transformer for grid connection. This unit effectively addresses the instability and periodicity issues of wind and photovoltaic (PV) energy, ensuring smooth and reliable energy supply.

Structurally, the integrated unit consists of six key components: Energy Storage Converter (PCS), busbar bridge, low-voltage compartment (for communication + power distribution), dry-type transformer, high-voltage compartment (equipped with vacuum load switch/circuit breaker), and an outer enclosure. With its prefabricated design and all-in-one structure, it simplifies on-site deployment and operation, making it a core device for modern energy storage and new energy grid-connection projects.

Key Features

• Compact Size & High Integration: Boasts a small volume, compact structure, and high integration level, significantly reducing land occupation. This makes it ideal for projects with limited on-site space (e.g., distributed energy projects).

• Factory Prefabrication & Debugging: All manufacturing, assembly, wiring, and debugging processes are completed in the factory. The unit is transported to the project site as an integral cabinet, eliminating complex on-site assembly work.

• Easy Installation & Cost Savings: On-site installation is simple, requiring no extensive infrastructure construction. This reduces infrastructure costs, shortens the construction period, and enables rapid power supply.

• Low Maintenance & Unattended Operation: The unit features simple equipment maintenance, and no dedicated personnel are required for on-site 值守 (unattended operation). This lowers long-term operational and labor costs.

• Stable & Fire-Retardant Dry-Type Transformer: The internal dry-type transformer ensures stable operation and is maintenance-free. It also has fire-retardant properties, meeting higher fire safety requirements for energy storage facilities.

• Corrosion & UV-Resistant Enclosure: The outer enclosure undergoes a special treatment process, providing excellent anti-corrosion and anti-exposure (UV-resistant) performance. It can effectively resist sand erosion, adapting to harsh outdoor environments.

• Remote-Controllable High-Voltage Components: The high-voltage compartment is equipped with a vacuum load switch/circuit breaker that supports remote control. It also offers comprehensive protection functions (e.g., overcurrent, short-circuit protection), enhancing operational safety and convenience.

• Wide Environmental Adaptability: Designed to withstand extreme temperatures, high altitudes, and strong winds, it can operate stably in diverse climatic conditions, ensuring reliability in different project scenarios.

Technical Specifications

Application Scenarios 

1. Distributed PV/Wind Energy Projects: Suitable for distributed solar or wind projects in residential areas, industrial parks, and commercial buildings. Its compact size and easy installation fit limited on-site space; the unit stores surplus energy generated during peak production periods and supplies it during low-production periods, solving the instability of distributed new energy.

2. Grid-Tied Energy Storage Stations: As a core device in large-scale grid-tied energy storage stations, it coordinates with battery systems to provide peak shaving (reducing grid load during high demand) and valley filling (storing energy during low demand). The remote-controllable high-voltage components also support unified dispatching by the power grid, enhancing grid stability.

3. Islanded/Remote Area Microgrids: Ideal for microgrids in rural areas, mining regions, or islands with limited access to the main grid. It stores energy from local solar/wind systems and supplies stable power to local loads (e.g., residential electricity, industrial equipment). The fire-retardant dry-type transformer and anti-corrosion enclosure ensure safe operation in remote, harsh environments.

4. Industrial & Commercial Energy Storage Systems: For industrial and commercial users (e.g., factories, shopping malls), the unit helps reduce electricity costs by storing energy during off-peak hours (low electricity prices) and using it during peak hours (high electricity prices). It also provides backup power support during grid outages, ensuring uninterrupted production and business operations.
