Large Scale Energy Storage Solutions

LSES is an intelligent and modular power supply equipment integrating various sizes of lithium battery and bi-directional inverter solutions.

Depending on the different application scenarios, lithium battery, bidirectional DC / AC converter, bidirectional DC / DC converter, Static switch and Power management system can be arbitrarily combined to realize the following

• grid connected power supply,
• off grid power supply
• off grid uninterrupted power supply
• power supply, static reactive power compensation,
• harmonic suppression
• other functions (e.g. Solar Interfaces and EV Charger Interfaces.

The system can have access to new energy, power grid, diesel generator and to reasonable configuration, scientific utilization, to provide users with green, environmental protection, noise free, high reliability and high security power services.

Configuration

AC/DC Module (PCS System)

Bidirectional AC / DC converter can realize the bidirectional conversion from DC to AC and AC to DC. It can not only convert AC to DC to charge the battery, but also convert DC to AC to supply power to load or feed back to the power grid.

Battery System

The system mainly consists of safe, efficient and long-life lithium iron phosphate cells, which are connected in series to form battery modules, and multiple modules are connected in series to form battery clusters.

Battery Management System

The core components of the system can effectively protect the battery from overcharge, over discharge and over-current. At the same time, the balanced management of the cells can ensure the safe, reliable and efficient operation of the whole system.

Power Management System

System operation data monitoring, operation strategy management, historical data record, system status record, etc.

Static Transfer Switch (Optional)

Under normal working conditions, the static switch is closed. When the power supply is interrupted, the static switch is immediately disconnected. The system turns to off grid power supply, and the battery is discharged for the load.

Enclosure (Housing)

A container of required size to fit all potential components that is IP 54 protected.

Air Conditioning

Air Conditioning (HVAC) system is configured to maintain the optimal temperature to maximize energy system operational life and efficiency.
