Frequently Asked Questions

What cell chemistry is utilized in these battery systems?

The systems utilize premium Lithium Iron Phosphate (LiFePO4) chemistry, recognized for its exceptional thermal safety, eco-friendliness, stability, and long cycle life.

What is the expected cycle life of the RackArk-HV system?

The system delivers a robust cycle life of ≥6000 cycles under conditions of 25±2°C, 0.5C/0.5C charge/discharge, up to an End of Life (EOL) of 70%.

Which communication protocols are compatible with this system?

The battery modules support multiple communication interfaces, including CAN2.0, RS485, and WiFi, enabling seamless integration with a wide variety of inverters and monitoring systems.

Can the system be installed outdoors?

The enclosure holds an IP20 rating, which is specifically designed for secure indoor rack-mounting installations. It is recommended to deploy the system in temperature-controlled and dry environments.

What is the recommended depth of discharge (DoD) for the battery?

To maintain optimal cycle performance and maximize the overall lifespan of the energy storage modules, we recommend keeping the Depth of Discharge (DoD) at 90%.

What are the storage temperature guidelines for the modules?

The recommended storage temperature range is between 0°C to 35°C to preserve the battery health and prevent capacity degradation over time.
