Project Background
In Hotan, Xinjiang, combating desertification requires reliable power for large-scale irrigation systems. This project implemented a solar-plus-storage solution to provide continuous energy for water pumps, replacing traditional diesel generators and advancing green energy adoption.
Project Challenges
-
Remote Location: Limited or no grid access in desert areas
-
Intermittent Solar Generation: Highly dependent on sunlight, causing unstable supply
-
Harsh Conditions: Requires compact, highly integrated, and robust energy storage systems
Solution
The system deployed 86 units of Enjoypowers 30kW On/Off-Grid PCS with STS, integrated with advanced energy storage cabinets:
-
Seamless Grid/Off-Grid Transition: Built-in Static Transfer Switch (STS) enables millisecond-level switching for uninterrupted operation
-
Highly Integrated Design: Each cabinet includes PCS, EMS, BMS, thermal management, and fire protection for simplified deployment
-
24/7 Stable Supply: Energy storage balances solar fluctuations, ensuring reliable irrigation power day and night
