How Solar Combiner Box Works

Step-by-Step Protection Process:

1. Solar Panel Connection: Each of 8 solar strings connects to individual input terminals
2. Fuse Protection: DC current flows through dedicated 10×38mm fuse for each string
3. MCB Protection: 2-pole DC MCB provides overcurrent and short circuit protection
4. Surge Protection: SPD diverts voltage spikes and lightning surges to ground
5. Combined Output: Protected DC power combines into single output to inverter/charge controller

Protection Benefits:

• Overcurrent Protection: MCBs trip during excessive current, protecting panels and cables
• Short Circuit Safety: Automatic disconnection prevents fire hazards
• Lightning Protection: SPD handles indirect lightning strikes and switching surges
• Individual String Monitoring: Each string protected independently

Frequently Asked Questions (FAQ)

Product Compatibility & Installation

Q: Is this combiner box suitable for all solar panel brands available in Bangladesh? A: Yes, it’s compatible with all standard solar panels including popular brands like JinkoSolar, Canadian Solar, Trina Solar, and local brands, as long as they use MC4 connectors and operate within 600V DC.

Q: Can I use this for both grid-tie and off-grid solar systems? A: Absolutely! The combiner box works with any DC solar system configuration – grid-tie with inverters, off-grid with charge controllers, or hybrid systems.

Q: Do I need 8 solar strings or can I use fewer? A: You can use anywhere from 1 to 8 strings. Unused inputs should be left disconnected. The combiner box will work efficiently with any number of connected strings.

Q: What size solar system is this suitable for? A: Typically suitable for 3kW to 15kW systems, depending on panel wattage and string configuration. For larger systems, multiple combiner boxes can be used.

Technical Specifications & Protection

Q: What does the SPD (Surge Protection Device) actually protect against? A: The Type 2 SPD protects against:

• Indirect lightning strikes (most common in Bangladesh)
• Switching surges from inverters
• Grid disturbances in grid-tie systems
• Voltage spikes from nearby electrical equipment

Q: How do I know when fuses need replacement? A: Fuses typically blow only during serious faults like short circuits. Signs include:

• No output from a specific string
• Visual inspection shows blown fuse element
• System monitoring indicates string failure
• MCB trips repeatedly for the same string

Q: What’s the difference between MCB and fuse protection? A:

• MCB: Resettable protection for overcurrent, can be switched on/off manually
• Fuse: One-time protection that blows during severe faults, must be replaced
• Both provide different levels of protection for comprehensive safety

Q: Can this handle Bangladesh’s extreme weather conditions? A: Yes, designed for harsh conditions:

• Temperature: -25°C to +60°C (covers Bangladesh’s range)
• Humidity: Up to 95% relative humidity
• Water: IP65 rating withstands heavy monsoon rains
• UV: UV-resistant materials prevent degradation

Installation & Maintenance

Q: Do I need an electrician to install this? A: Yes, we strongly recommend professional installation by certified electricians familiar with solar systems and local electrical codes for safety and warranty compliance.

Q: Can it be installed outdoors during monsoon season? A: The IP65 rating makes it suitable for outdoor installation, but for best results, install during dry weather and ensure all cable entries are properly sealed.

Q: How often does it need maintenance? A: Recommended maintenance schedule:

• Monthly: Visual inspection of indicator lights and connections
• Quarterly: Check for physical damage, clean if dusty
• Annually: Professional inspection of all protection components
• As needed: Fuse replacement if blown

Q: What tools are needed for installation? A: Basic electrical tools including:

• MC4 crimping tool for solar connectors
• Screwdrivers for mounting
• Wire strippers and electrical tape
• Digital multimeter for testing
• Appropriate safety equipment

System Performance & Monitoring

Q: How do I know if the combiner box is working properly? A: Indicators of proper operation:

• All MCBs in “ON” position
• No visible fuse failures
• Normal DC voltage output
• No error indicators on connected inverter/charge controller

Q: Will this reduce my solar system’s efficiency? A: No, when properly installed, voltage drop is minimal (less than 1%). The protection benefits far outweigh any minimal losses.

Q: Can I monitor individual string performance? A: The combiner box doesn’t include monitoring, but you can add DC current sensors or use inverter monitoring to track individual string performance.

Q: What happens during a lightning storm? A: The SPD automatically diverts surge voltage to ground, protecting your equipment. However, for direct lightning strikes, additional protection may be needed.

Business & Delivery

Q: Is this approved for commercial solar installations in Bangladesh? A: Yes, it meets international standards typically required for commercial installations. Always verify with your local utility and installation authority for specific requirements.

Q: What’s included in the warranty? A: Manufacturer warranty covers:
