Frequently Asked Questions (FAQ)

Dual String System Design

Q: What’s the advantage of dual string design over single string? A: Key benefits include:

• Independent optimization: Each string can have different panel orientations
• Shading tolerance: Shading on one string doesn’t affect the other
• Future expansion: Add panels to one string without affecting the other
• Better monitoring: Track performance of each string separately
• Higher reliability: System continues working if one string fails

Q: Can I use different wattage panels on each string?

A: Yes, with dual MPPT inverters, each string can have different panel types, wattages, or orientations. The MPPT controllers optimize each string independently.

Q: How many panels should I put on each string?

A: Typically 6 panels per string as designed, but depends on:

• Panel voltage and inverter MPPT voltage range
• Total system wattage requirements
• Roof space and layout constraints
• Shading and orientation considerations

Q: Is this suitable for East-West roof orientations?

A: Perfect! Put East-facing panels on one string and West-facing on another. Each MPPT controller will optimize for different sun conditions throughout the day.

Technical Specifications & Compatibility

Q: What’s the maximum panel wattage this can handle?

A: With 30A per string rating, it can handle:

• 540W+ panels: Up to 6 panels per string safely
• 600W+ panels: Perfect for modern high-efficiency panels
• Total system capacity up to 7.2kW (12 × 600W panels)

Q: Is 600V DC rating sufficient for large panels?

A: Yes, for most residential installations:

• 6 × 540W panels ≈ 300V (well within 600V limit)
• Suitable for 99% of residential and small commercial systems
• For higher voltages, consider the 1000V version

Q: Which dual MPPT inverters work best with this?

A: Recommended brands available in Bangladesh:

• DC cables: Properly sized for 30A per string
• MC4 connectors: For panel connections
• Grounding equipment: For electrical safety
• Mounting hardware: Appropriate for installation surface
• Labels and documentation: For code compliance

Q: How do I size the cables from combiner to inverter?

A: Cable sizing considerations:

• Current capacity: Must handle 30A per string safely
• Voltage drop: Keep under 2% for efficiency
• Distance: Longer runs need larger cables
• Environmental factors: UV resistance for outdoor runs

Protection & Safety Features

Q: How does the Type II SPD protect my system?

A: The SPD protects against:

• Lightning surges: Both direct and indirect strikes
• Grid switching surges: From utility operations
• Inverter switching: Internal inverter transients
• Inductive loads: From nearby motors and transformers

Q: What happens if one string fails?

A: System benefits from redundancy:

• Continued operation: Other string keeps producing power
• Easy identification: Monitoring shows which string failed
• Safe isolation: MCB allows safe disconnection for repairs
• Minimal downtime: Fix one string while other operates

Q: How often should I inspect the combiner box?

A: Recommended inspection schedule:

• Monthly: Visual check of indicator lights and connections
• Quarterly: Open and inspect for corrosion or damage
• Annually: Professional inspection and testing
• After storms: Check for surge damage or water ingress

Q: What are signs of SPD activation?

A: Indicators that SPD has operated:

• Visual indicators: Many SPDs have status windows
• System monitoring: Inverter may show surge events
• Performance changes: Sudden system performance issues
• Physical inspection: Signs of SPD component activation
