500kw 1075Kwh Commercial Energy Storage System Integrated Ess

System for integrated energy storage with modular pieces for simple upkeep and growth; expandable based on scenario-specific system capacity requirements.

      The system integrates energy storage converter, storage battery, isolation transformer, cooling, fire protection, power distribution, dynamic loop monitoring and energy management, friendly grid adaptability, accepting grid scheduling, active and reactive power compensation, supporting peak shaving and valley filling, demand-side response, and assisting in new energy grid-connected applications, etc. The IP54 protection level adapts to the harsh outdoor
environment, which is perfectly suited to the needs of industrial and commercial energy storage. 

• Peak shaving and valley filling:
       During off-peak hours of time-of-use electricity pricing: The energy storage unit automatically charges and goes into standby mode after being fully charged.During peak hours of time-of-use electricity pricing: The energy storage unit automatically discharges, realizing arbitrage based on the price difference between peak and off-peak hours, thereby enhancing the economic benefits of the photovoltaic (PV) + energy storage + charging system.

• PV and energy storage integration:
       Real-time monitoring of local load power is conducted, with PV power generation prioritized for self-consumption, and excess power stored.If the PV power generation is insufficient to meet local load demand, battery storage is preferentially utilized.When the off-grid battery discharges to the set lower limit of the State of Charge (SOC), manually trip the grid power switch and close the diesel generator switch to start the diesel generator and continue supplying power to the load.When grid power is restored, manually trip the diesel generator switch and close the grid power switch, allowing the system to operate in grid-connected mode.

• Diverse Functions: It supports peak shaving and valley filling, demand-side response, backup power supply, and other major functions; it enables remote updates of operational strategies and firmware upgrades, resulting in lower operation and maintenance costs;

• Flexible and Convenient: Modular PCS allows for linear expansion of battery units and bidirectional energy storage inverter units; it possesses independent charging and discharging control capabilities for multiple battery packs, enhancing battery utilization and safety;

• High Integration: The system is productized, integrating energy storage batteries, PCS(Power Conversion System), power distribution, temperature control, fire protection, water immersion door sensors, and monitoring communication, providing comprehensive control over the system's operational status and risks; one-stop delivery shortens the on-site installation and commissioning period of the project；

• Safe and Intelligent: A fault escalation handling mechanism responds to preset fault scenarios; customized BMS (Battery Management System) provides comprehensive measurement and protection functions; it supports cloud-based dispatching and operational report analysis.
