Outdoor IP65 48V 200Ah LiFePO4 Telecom Tower Battery Rack Cabinet System 10kWh Backup Power

The BEL-TTO48200 is a fully integrated outdoor-rated 48V 200Ah Lithium Iron Phosphate (LiFePO4) telecom tower battery system housed in an IP65 weatherproof floor-standing cabinet. Delivering 9.6 kWh of backup capacity with integrated thermal management, surge protection, and remote monitoring, this turnkey outdoor system eliminates the need for costly climate-controlled equipment shelters at tower sites. Simply position the cabinet on a concrete pad at the tower base, connect DC power and communication cables, and the site is ready for operation. The BEL-TTO48200 represents the most cost-effective path to reliable outdoor telecom backup power, reducing site construction costs, accelerating deployment timelines, and providing decades of maintenance-free service.

The traditional approach to telecom site power involves constructing a climate-controlled equipment shelter or cabinet to house batteries, rectifiers, and transmission equipment. This shelter represents a significant portion of total site cost and construction timeline, particularly at remote locations where transporting building materials and concrete is logistically challenging. The BEL-TTO48200 eliminates the shelter requirement for the battery subsystem by integrating all necessary environmental protection, thermal management, and safety systems directly into the battery cabinet. The IP65-rated enclosure provides complete protection against dust ingress and low-pressure water jets, while the integrated HVAC system maintains optimal internal battery temperature regardless of external conditions from -30°C to 55°C.

• Outdoor IP65 Weatherproof Cabinet: The fully sealed enclosure provides complete protection against dust, rain, snow, and water jets from any direction, enabling direct outdoor installation without additional shelter or weather protection. Powder-coated steel construction with stainless steel hardware ensures decades of corrosion resistance in coastal, industrial, and tropical environments.
• 200Ah High-Capacity Backup: With 200Ah at 48V, the BEL-TTO48200 delivers 9.6 kWh of total stored energy, providing extended backup runtime for macro base station equipment during grid outages. The 200A continuous discharge capability supports high-power sites with multiple sectors, remote radio heads, and microwave backhaul equipment.
• Integrated Turnkey System: The cabinet arrives factory pre-configured with all battery modules installed and connected, BMS commissioned, HVAC tested, and surge protection wired. On-site work is limited to positioning, securing, and connecting DC power and communication cables, reducing deployment time from weeks to days compared to traditional shelter-based installations.
• Built-in Environmental Control: An integrated HVAC system with heating and cooling maintains internal cabinet temperature within optimal range regardless of external conditions. Redundant fan configuration with automatic failover ensures continuous thermal management. The system includes condensation management to prevent internal moisture accumulation in humid environments.
• Comprehensive Remote Monitoring: The 3-tier BMS communicates via RS485, CAN, Modbus TCP, and SNMP for seamless integration with network operations center platforms. Real-time monitoring of battery status, cabinet temperature, door status, surge protection health, and HVAC operation enables proactive maintenance and rapid fault diagnosis without site visits.

The BEL-TTO48200 is engineered for outdoor telecom tower installations where traditional equipment shelters are impractical or cost-prohibitive. Primary deployments include greenfield macro base station sites requiring rapid deployment with minimal civil works, tower site upgrades where existing shelter space is fully utilized and additional battery capacity must be installed externally, remote and hard-to-access sites where transporting shelter construction materials is logistically challenging, rooftop installations where indoor space is unavailable or weight-restricted, and temporary or disaster recovery telecom sites requiring rapid deployment of self-contained backup power. The outdoor cabinet format also supports co-location scenarios where multiple operators share tower infrastructure but require independent battery systems.

Each BEL-TTO48200 completes comprehensive factory acceptance testing including full system integration testing, HVAC performance verification, IP65 ingress protection validation, BMS redundancy failover testing, and 96-hour continuous burn-in. The cabinet is shipped as a complete unit on a custom pallet with shock indicators and moisture sensors. BEL provides a standard 5-year system warranty with optional extended coverage and annual preventative maintenance service agreements.
