Product Description
The combiner box can be divided into three types in terms of function. The first type is the basic type, without anti backflow and monitoring functions; The second type is equipped with anti reverse function and does not have monitoring function; The third type, which has both anti anti anti anti backflow and monitoring functions, is the most versatile, cost-effective and cost-effective combiner box.
Name of combiner box components and their main impacts:1. Circuit breaker and isolation switch: used for isolation; Easy to cut off power for maintenance on the load side
2. Photovoltaic fuse: prevents the line from withstanding excessive current or short-circuit current, and protects photovoltaic modules
3. DC Surge protector: to prevent inductive lightning stroke
4. Anti reverse current diode: To prevent reverse power transmission from high voltage string to low voltage string, but it will cause power loss and require additional heat dissipation devices
5. Monitoring unit (intelligent controller): monitoring current, Surge protector status, etc. to realize data communication
6. Voltage transmitter and self powered power supply: providing working power to the intelligent controller
