Overview
The 1MWh containerized energy storage system is a fully integrated 20-foot container battery energy storage solution for commercial and industrial applications. It comes pre-wired and pre-tested inside a standard shipping container, greatly shortening on-site installation time. It can work with solar PV panels, the utility grid and diesel generators to deliver peak shaving, load shifting, emergency backup power and off-grid supply.
Pre-wired, pre-tested and shipped as one unit — fast deployment and easy transportation by road, rail or sea.
Only cable connection is needed on site
Cell, module and system level layered protection with real-time thermal monitoring and fault isolation for zero-trip safety.
High-safety LiFePO4 battery pack inside
Compatible with solar, grid and diesel genset, and able to switch between on-grid VAR support, off-grid islanding and micro-grid operation.
Multi-mode operation in one click
Real-time status check and remote control over 4G, with local RS485 / CAN communication to existing on-site systems.
No need to visit the site to read the meter
Multiple containers can be paralleled for larger energy projects — start at 1MWh and grow.
Capacity, power and protocol customization on request
Fully compliant with IEC / IEEE interconnection rules and able to accept utility dispatch in real time.
Advanced anti-islanding with sub-cycle detection and ride-through
System Topology
The container sits at the center of your site’s power system: solar, grid and diesel generation feed it, and it serves your loads while reporting everything to the cloud.
Ground-mount or rooftop PV feeds the container. Excess solar generation is stored instead of curtailed, and released when it is worth more.
The utility grid charges the battery bank through the electricity meter at off-peak tariff. AC output 400V (−20% ~ +15%), 722A rated current.
Existing diesel gensets keep running as backup — the BESS cuts their running hours and fuel burn, and covers loads while generators start.
Factory and mall loads are served around the clock, while the EMS reports operating data to the cloud platform over 4G for remote monitoring.
The whole flow is automatic: the energy management system decides when to charge, when to discharge and when to hold reserve capacity, so your facility always runs on the cheapest available power.
What’s Inside
The container integrates battery packs, PCS, BMS, EMS, fire suppression and thermal management — every component passes strict factory testing before delivery.
1680Ah / 598.4V battery bank rated 1005.3kWh, with over 6000 cycles of expected life.
Cell-module-system layered protection, real-time thermal and fault isolation.
Rated 500kW (peak 550kW), 722A rated / 794A maximum AC current, with on-grid, off-grid and micro-grid modes.
Schedules charge and discharge to tariff and utility dispatch; cloud platform for remote control.
Integrated fire suppression plus cooling to keep all battery packs within their operating window.
Power distribution inside the container; RS485 / CAN locally and 4G to the cloud.

Applications
Utility-scale adjacent storage for industrial users who need megawatt-hour capacity without a bespoke containerized plant.
Peak shaving that cuts high electricity demand charges for continuous production lines.
Reliable uninterrupted backup power when the grid fails or is not available at all.
Maximize self-consumption of renewable generation and reduce electricity bills significantly.
Islanding, micro-grid and demand response in one container.
Buffer high-power charging draw and avoid demand spikes.
Load shifting and centralized demand management across tenants.
Packing & Delivery
