❓ Frequently Asked Questions
What is the cycle life of your battery systems?
Our battery systems offer a cycle life of ≥6000 cycles at 25±2°C with 0.2C charging/discharging, until reaching 70% of End of Life (EOL).
Does the system support both On-grid and Off-grid modes?
Yes, our PCS (Power Conversion System) is designed to handle both On-grid and Off-grid AC output, making it versatile for various energy scenarios.
What protection features are included in the Battery Energy Storage System (BESS)?
The system includes comprehensive protection for voltage (over charge/discharge), temperature range, current/leakage, and dielectric withstand voltage (1000VDC).
What is the recommended Depth of Discharge (DoD)?
We recommend a Depth of Discharge (DoD) of 90% to maintain optimal battery health and longevity.
What are the communication methods supported?
The systems support two-way communication via CAN2.0 and RS485 protocols for seamless integration with monitoring software and PCS.
Is the equipment suitable for outdoor installation?
