Q : 1. What is this 1MW container ESS designed for? A : It's built for commercial and industrial users needing solar integration, peak shaving, backup power, and grid-side support.
Q : 2. What are the main system components inside? A : It includes LFP batteries, modular PCS, ATS, PV inverters, HVAC, fire suppression, and an integrated energy management system.
Q : 3. How is thermal and fire safety handled? A : The system uses air cooling and includes gas-based fire suppression (perfluorohexane or heptafluoropropane) with multi-sensor detection.
Q : 4. Does it support both on-grid and off-grid operation? A : Yes, it features automatic transfer switching between grid and diesel modes, plus PV priority and anti-backflow control.
Q : 5. What are the key electrical specifications? A : 1MW rated AC power, 832V battery voltage, 672–864V range, <3% THDi, and 98% max system efficiency.
Q : 6. How is the system monitored and controlled? A : Through EMS with RS485, CAN, Ethernet, and LCD interface for local + remote access, dispatch, strategy updates, and real-time logs.
