10kW Photovoltaic Combiner Box Price List OEM

The price of a 10kW PV combiner box typically ranges from $150 to $500, depending on features, brand, and configuration.

Price Overview

For a 10kW solar system, combiner boxes are designed to handle multiple PV strings and provide overcurrent and surge protection. Retail prices for suitable combiner boxes are generally:

• Amazon: PV combiner boxes for 8–10kW systems are available around $150–$250, featuring IP65 waterproof rating, DC/AC circuit breakers, and surge protection for single-phase systems (e.g., Temank 10kW distribution box) .
• Midnite Solar / Solar Store: Pre-wired combiner boxes for 10kW systems range from $275 to $500, depending on the number of input strings, DC breakers, and additional features like disconnect switches and monitoring .
• Alibaba / Wholesale Suppliers: Industrial or bulk options for 10kW systems can start as low as $55–$150 per unit, often with IP65 protection and 2–4 string inputs, suitable for commercial or DIY installations .
• ETEK Solar: Offers 1000V DC combiner boxes for medium to large-scale systems, with prices typically in the $200–$400 range for dual-string or triple-string configurations, including surge protection and robust enclosures .

Factors Affecting Price

1. Number of Input Strings: More strings increase the number of fuses or breakers, raising the cost.
2. Voltage and Current Ratings: Higher voltage (600V–1000V) and higher current capacity require more robust components.
3. Protection Features: Built-in surge protection, DC isolators, and arc-fault detection add to the price.
4. Material and IP Rating: Metal enclosures and IP65/IP66 ratings for outdoor use are more expensive than basic ABS plastic boxes.
5. Brand and Warranty: Established brands like Midnite Solar or ETEK Solar often cost more but provide better reliability and support.

Recommendation

For a 10kW residential or small commercial system, a combiner box in the $200–$350 range with IP65 protection, DC breakers, and surge protection is typically sufficient. For larger or industrial setups, consider higher-rated boxes with multiple input strings and enhanced safety features. By selecting the right configuration, you can ensure safe, efficient, and durable operation of your 10kW solar PV system while staying within budget.
