The GearUP 8-Way DC PV Combiner Box is designed for reliable solar power system integration. It combines DC inputs from up to 8 solar panel strings into a single output, featuring built-in protection components including Miniature Circuit Breakers (MCB), fuses, and Surge Protection Devices (SPD). Its IP65-rated waterproof enclosure ensures durability in outdoor environments. Ideal for residential and commercial solar installations, this combiner box enhances system safety and efficiency.

Key Description:

• Combines up to 8 solar panel strings into a single DC output
• Integrated 2-pole DC MCB and fuse protection for each string
• Type 2 SPD safeguards against voltage surges caused by lightning or switching
• IP65-rated, weather-resistant enclosure suitable for indoor and outdoor use
• Compatible with MC4 connectors and standard solar cables

Features & Specifications:

• Strings Supported: 8 In / 1 Out
• DC Voltage Rating: Up to 600V DC
• DC MCB: 2-pole, rated for overcurrent protection
• Fuse Holder: 600V DC, 10x38mm fuse link for each string
• Surge Protection Device: Type 2, 600V DC surge handling
• Enclosure: IP65 waterproof, UV resistant, made of fire-retardant ABS/Polycarbonate
• Operating Temperature: -25°C to +60°C
• Mounting: Wall or panel mount with included brackets
• Cable Entry: PG glands and MC4-compatible ports

Benefits:

• Ensures safe and reliable connection of multiple solar panel strings
• Prevents damage from overcurrent and short circuits with resettable MCBs and quick-replace fuses
• Protects sensitive solar equipment from voltage spikes using SPD
• Durable waterproof design suitable for harsh weather conditions
• Simplifies solar system wiring and maintenance

Pros:

• High-quality protection components integrated
• Weatherproof and UV-resistant enclosure for outdoor use
• Easy to install and maintain with wall or panel mounting options
• Compatible with common solar connectors and cables
• Compact design saves space in solar installations

Cons:

• Limited to 8 input strings, may not suit very large solar arrays
• Requires basic electrical knowledge for installation and maintenance
• SPD protects against Type 2 surges but may need additional protection for extreme conditions

How It Works:

1. Solar Panel DC output (1 string) is connected to the combiner box.
2. The DC power flows through the fuse, then through the MCB, and finally through the SPD.
3. The SPD protects the system by diverting sudden voltage spikes to ground.
4. The combined and protected output is then sent to the inverter/charge controller.
