Frequently Asked Questions
Q What is the cycle life of this high-voltage battery system?
The battery system has a designed cycle life of ≥6000 cycles at 25±2°C, 0.2C/0.2C testing conditions, and down to 70% End of Life (EOL).
Q Does the system support both on-grid and off-grid configurations?
Yes, the system is designed to operate seamlessly in both configurations. Under off-grid mode, it provides a rated AC power of 275KVA and active power of 250KW. Under on-grid mode, it handles 275KVA with standard power factor capabilities (1.0 standard, lead 0.8/lag 0.8).
Q What is the protection level and outdoor suitability of the container?
The containerized system features an IP65 protection rating, which ensures high resistance to dust, wind, and water ingress. The battery system is rated for an operational temperature range of -10°C to 50°C.
Q What safety and protective functions are integrated into the battery system?
The system comes with comprehensive protective mechanisms, including voltage protection (over-charge and over-discharge), temperature protection (over-temperature range protection), current/leakage protection, and a dielectric withstand voltage rating of 1000VDC (not less than 1 GΩ).
Q How do users monitor and communicate with the BESS?
The battery side uses a two-way CAN2.0/RS485 protocol for local and remote communication. Users can inspect parameters directly using the built-in 10-inch LCD display or connect to a dedicated PC monitoring software.
Q What are the main components and certifications of the PCS side?
The PCS side supports a max photovoltaic power of 360KW with 10 PV input channels. It incorporates grid certifications including TUV and CE, working across standard 50/60Hz grid frequencies.
