The 500 kW / 1200 kWh containerized Battery Energy Storage System (BESS) is a compact, fully integrated energy storage solution designed for commercial, industrial, and utility-scale applications. Housed in a standard 20-foot container, it combines high-efficiency lithium-ion batteries, a hybrid inverter, and advanced energy management systems into a plug-and-play solution.
Key Features
High Power & Energy Capacity: 500 kW rated power with 1200 kWh energy storage to meet high-demand load and energy shifting requirements.
Compact & Modular Design: Standard 20FT container footprint, easy to transport, install, and expand.
Hybrid Inverter Integration: Supports DC-coupled PV integration, on-grid/off-grid operation, and seamless power management.
Advanced Battery Management System (BMS): Ensures safe, reliable, and long-life operation of lithium batteries.
Flexible Operation Modes: Peak shaving, load shifting, renewable self-consumption optimization, emergency backup, and grid support.
Remote Monitoring & Control: Real-time monitoring via web or app, supporting predictive maintenance and energy optimization.
All major components—including the hybrid PCS, battery racks, BMS, EMS, HVAC, fire suppression system, and electrical protection units—are pre-installed inside a standard 20-foot container, ensuring fast installation and reduced on-site construction time. The Megarevo 500kW hybrid inverter allows seamless integration of PV, battery, and grid, supporting functions such as self-consumption optimization, peak shaving, load shifting, backup power, and seamless on/off-grid switching.
With a compact containerized design, high system efficiency, and scalable architecture, this 500kW / 1200kWh Hybrid BESS is ideal for factories, commercial buildings, solar power plants, industrial parks, microgrids, and remote areas, helping users enhance energy independence, improve power reliability, and reduce overall energy costs.
This system adopts a DC-coupled hybrid energy storage architecture, integrating solar PV, battery storage, grid, and generator into one intelligent energy management platform.
During the daytime, solar power is prioritized to supply the load. Excess PV energy is stored directly in the battery through the hybrid inverter with high efficiency. When solar generation is insufficient, the system automatically draws power from the battery or the grid to ensure stable power supply.
At night or during peak electricity price periods, the battery discharges to support the load, reducing grid consumption and lowering energy costs. In case of grid outage, the system can seamlessly switch to off-grid mode, supplying power to critical loads using PV, battery, and generator without interruption.
The built-in energy management system intelligently coordinates PV, battery, grid, and generator operation, enabling functions such as self-consumption optimization, peak shaving, load shifting, backup power, and microgrid operation, making it an ideal solution for commercial, industrial, and hybrid solar + storage applications.
