✅ Solar PV switchboards ( PVDB Photovoltaic Distribution Boards)
Power Distribution: directs electricity from renewable sources to Load or the Grid
System Protection: Includes circuit breakers, fuses and surge protection to safeguard equipment
Grid Synchronization: Interfaces with Utility Grid to match voltage, frequency, and phrase
Monitoring & Control: Measures power generation, consumption, and battery/storage level
Isolation & Maintenance: Allows safe disconnection for service or emergencies
✅ Functions of a PVDB:
- Collects power from multiple solar panels or strings
- Combines DC outputs through fuse protection (string combiner function)
- Provides circuit protection against overcurrent, short circuit, and reverse polarity
- Distributes power to inverters or AC distribution boards
- Ensures system safety with isolators, surge protection devices (SPD), and monitoring
✅ Typical Components:
- DC fuses or MCBs
- Surge protection device (SPD)
- DC isolator switches
- MC4 connectors or busbars
- Enclosure with IP-rated protection (IP65–IP66 for outdoor use)
✅ Applications:
- Rooftop solar PV systems (residential & commercial)
- Ground-mounted solar farms
- Hybrid solar + battery installations
- Solar pumping and off-grid systems
