Power Supply Mode: PBG Mode Solar power supplies the load first. Excess energy is used to charge the battery; When solar power is insufficient to meet load demand, the battery will discharge to supply power together with solar; If both solar and battery power are insufficient, the grid will automatically supplement the load supply.

Daytime Operation: Under good sunlight conditions, the system achieves 100%photovoltaic-powered operation for 8hours, with solar energy directly supplying the load and excess power charging the battery storage

Nighttime Power Supply: The energy storage system provides continuous power supply for more than 3 hours, ensuring uninterrupted refrigeration during off-sunlight periods.

Daily Energy Saving: The system achieves an energy saving rate of 45%on a daily basis under ideal conditions, significantly reducing grid electricity consumption.

Annual Energy Saving Projection: Based on seasonal irradiance variations and operational cycles, the system is expected to achieve an average annual energy saving ofover 30%, making it highly efficient for long-term cold chain applications.

Parameter Basis: Light intensity is 1000W/m², ambient temperature is 20℃, and air quality is 1.5
