Features
- Long Service Life with Stable LFP Chemistry - The SLB48-100-135-5H uses iron-based lithium technology designed for extended operational life. It delivers up to 8000 cycles at full depth of discharge and maintains a 15-year calendar life, offering a reliable long-term alternative to traditional VRLA systems.
- Wide Operating Temperature Range - Engineered for varied Australian environments, the battery supports charging from -5 to +55 °C and discharging from -20 to +55 °C. This ensures consistent performance in both controlled indoor installations and remote, climate-exposed locations.
- Integrated Battery Management System - A built-in BMS provides cell balancing, charge and discharge protection, automated current limiting, and system-level alarms. Continuous supervision safeguards the battery against abnormal conditions, improving uptime and reducing maintenance requirements.
- Advanced Communication & Monitoring Capability - With dual RS485/RJ45 ports and Modbus support, the unit offers flexible integration with external controllers, DC power systems, and network monitoring software. Local management software (Studio) allows full visibility of battery status and performance parameters.
- Compact, Rack-Optimised 19” 3U Design - The lightweight 38.3 kg module fits standard 19-inch racks and occupies only 3U of height, enabling efficient use of space in telecom shelters, control rooms, and industrial cabinets. Its robust enclosure is rated to IP20 and built for reliable long-term operation.
- Embedded Safety and Protection Features - Safety functions include a BMS-controlled 100 A circuit breaker, compliance with IEC62619 and IEC62368 standards, and UN38.3 transport certification. The system is designed to support safe installation, handling, and operation throughout its lifecycle.
