Price quote for 48V off-grid power supply system for telecommunications sites

48V off-grid telecom power systems typically range from 1kW to 100A+ capacity, with pricing dependent on system configuration, battery type, and site requirements.

System Overview

A 48V off-grid power supply system for telecommunications generally includes: Rectifiers and DC power modules: Convert AC input to regulated -48V DC for telecom equipment. Modern rectifiers use high-frequency switching technology with efficiencies up to 95% and active power factor correction for stable output (Helios, EverExceed, Alibaba). Battery backup: Supports uninterrupted operation during AC outages.

Systems can integrate LiFePO₄ lithium batteries or sealed lead-acid batteries, offering long life, reduced maintenance, and high reliability for remote sites (Nuranu, KDS Electrical). Monitoring and control: Advanced systems include controllers with LLVD/BLVD, temperature compensation, auto voltage regulation, current limitation, battery capacity calculation, and online battery testing. Remote monitoring is supported via RS232, Ethernet, or dry contacts.

Modular and scalable design: Systems can be customized for indoor or outdoor deployment, with modular construction allowing easy replacement or expansion of rectifiers, inverters, or battery modules. Protection features: Over-voltage, over-current, short-circuit, and over-temperature protection ensure safe operation and prevent equipment damage. Typical ConfigurationsSmall-scale systems: 1kW rectifier with 48V battery bank, suitable for micro base stations or small telecom shelters (Helios HelSys).

Medium-scale systems: 48V 30A to 100A DC systems with integrated battery backup, ideal for standard BTS or edge data centers (Alibaba, KDS Electrical). Hybrid or renewable systems: Incorporate solar MPPT converters or hybrid energy sources for off-grid or remote sites, ensuring continuous operation in harsh environments (EverExceed ERP Series).

Pricing Considerations

Exact pricing depends on: System capacity: Higher wattage or amperage increases cost. Battery type and capacity: LiFePO₄ batteries are more expensive upfront but reduce long-term OPEX due to longer life and lower maintenance. Customization: Outdoor enclosures, hybrid energy integration, and advanced monitoring features add to the cost.

Quantity and supplier: Bulk orders or partnerships with manufacturers like Helios, EverExceed, or Nuranu may reduce unit cost. For a precise price quote, it is recommended to contact manufacturers directly with your site requirements, including load profile, backup duration, environmental conditions, and preferred battery technology.

Recommendation

For small to medium telecom sites, a 48V 30–100A system with LiFePO₄ batteries and integrated monitoring is typically sufficient. For remote or off-grid sites, consider hybrid systems with solar integration and weatherproof enclosures. Request custom quotes from multiple suppliers to compare costs, warranties, and service support.

This approach ensures a reliable, efficient, and cost-effective 48V off-grid power solution tailored to your telecommunications site needs.
