Quotation for 50kW Off-Grid Communication Power Supply System

A 50kW off-grid solar power system typically includes a 50kW PV array, 50kW inverter, and 100kWh battery storage, with prices ranging from approximately $7,000 to $35,000 depending on battery type and configuration.

System Components and Configuration

A standard 50kW off-grid system for communication or industrial use generally includes:

• Photovoltaic Panels: 50kW capacity, typically 450–600W per panel, requiring around 100–160 panels depending on wattage .
• Inverter: 50kW hybrid inverter converting DC to AC, supporting single-phase or three-phase loads .
• Battery Storage: 100kWh lithium-ion or gel battery bank, expandable based on load requirements .
• Optional Backup: Diesel generator or utility grid integration for continuous power during low solar availability .
• Mounting and Protection: Roof or ground mounts, temperature control, fire prevention, surge protection, and weatherproof enclosures .
• Monitoring: Intelligent remote monitoring system for fault alerts and maintenance .

Pricing Estimates

• Gel Battery Design: Around $34,195 for a complete turnkey system .
• Lithium Battery Design: Price varies; typically higher than gel batteries, requiring direct inquiry with suppliers .
• Off-Grid System Cost Range: Approximately $7,000–$35,000, depending on battery type, inverter technology, and additional features .

Energy Output and Coverage

• Daily Generation: 50kW solar panels can produce 200–300kWh per day, depending on local sunlight conditions .
• Annual Generation: Approximately 108,000kWh per year under average conditions .
• Load Support: Suitable for communication towers, industrial equipment, remote offices, or large-scale power-using devices .

Additional Considerations

• Customization: Suppliers can provide OEM labeling, packaging, and compliance documentation for export or local standards .
• Installation Space: Requires roughly 300–350㎡ for panel installation, with additional space for maintenance access .
• Lead Time: Varies by supplier; some offer sample orders for pilot validation and full project quotations within 24 hours . For an accurate quotation, it is recommended to provide the project location, load requirements, voltage specifications, preferred battery type, and expected annual energy consumption to the supplier. This ensures the system is tailored to your communication power needs and local environmental conditions.
