Technical parameter：

Working principle：

• Energy storage:When the photovoltaic system generates excess electrical energy, the alternating current (AC) is converted into direct current (DC) through the inverter and stored in the battery module.

• Energy release:When power demand increases or supply is insufficient, the stored direct current is converted into alternating current through the inverter and transmitted to the power grid or directly used by users.
  

• Intelligent scheduling:The EMS intelligently schedules the charging and discharging process of the energy storage system according to electricity prices, grid demands, and user settings to maximize economic benefits.

Application scenarios

1. Industrial and Commercial Peak-Valley Load Shifting

   Adaptation Advantages: 215kWh large capacity can store electricity at night with off-peak electricity prices and release it during peak hours in the daytime, reducing enterprise electricity costs (annual electricity    cost savings of approximately 20,000 USD); 100kW rated power is suitable for the electricity demand of small and medium-sized factories, supporting the "photovoltaic priority" mode to maximize the    utilization of clean energy.

2. Outdoor Photovoltaic Power Station Supporting

   Adaptation Advantages: IP54 protection and (-30℃~50℃) temperature resistance, suitable for harsh outdoor environments; modular cabinet design eliminates on-site assembly, with deployment completed    within 3 days; supports fast switching between off-grid and on-grid modes, suppresses fluctuations in photovoltaic output, and improves the power generation stability of the power station.

3. Backup Power Supply in Remote Areas

   Adaptation Advantages: 51.2kWh basic capacity can support emergency power supply for remote villages and base stations for 5-7 days; three-phase four-wire access is suitable for power grids in most areas    without the need for additional voltage converters; dual aerosol fire extinguishing design ensures safety in unattended scenarios.
