The Low-Voltage Energy Storage Grid-Tie Cabinet is the critical interface between battery energy storage systems and the low-voltage distribution grid. Designed for commercial and industrial applications, it ensures safe, intelligent, and efficient grid connection.
This cabinet integrates AC power collection, bidirectional energy metering, grid connection and disconnection control, auxiliary power supply, and 4G remote monitoring. Supporting up to six AC inputs, it can seamlessly pair with mainstream all-in-one energy storage cabinets.
With an IP55-rated enclosure, it is suitable for outdoor installation. Flexible customization options—including cabinet size, rated power, and core component selection—make it ideal for solar + storage, wind + storage, and hybrid energy projects.
Multi-Layer Electrical Protection
Built-in overcurrent, overvoltage, short circuit, and reverse current protection ensures both the grid side and user side are safe.
High Environmental Resilience
IP55-rated enclosure with optimized cooling design provides dust, water, and thermal stability for long-term outdoor operation.
Strong Renewable Energy Compatibility
Seamlessly connects to solar PV, wind turbines, and other distributed energy systems for hybrid storage applications.
Deep Customization Options
Cabinet dimensions, rated current/power, and core component brands—such as MCCBs, frame switches, and UPS—can be tailored to each project.
