- Functions and efficacy:
Confluence function: direct current confluence of multiple photovoltaic series, reducing the number of cables and simplifying system wiring.
Protection function: With over current, over voltage, lightning protection and other protection functions to ensure the safe operation of the system.
Monitoring function: Some bus boxes also have the monitoring function of current, voltage and other parameters, which is convenient for system operation and maintenance.
- Structural Composition:
Input terminal: used to connect the DC input of the photovoltaic series, usually with multiple input terminals.
Output terminal: Used to connect the DC output terminal of an inverter or a DC distribution cabinet.
Circuit breaker or fuse: Used to protect the circuit from overcurrent or short circuit.
Lightning protection module: Used to prevent system damage caused by lightning strikes.
- Application scenario:
Small photovoltaic power station: suitable for small distributed photovoltaic power generation system, such as household rooftop photovoltaic system.
Medium-sized photovoltaic power station: suitable for medium-sized industrial and commercial photovoltaic power generation systems, such as factories, shopping malls rooftop photovoltaic systems.
