1000V 1500V 100A 160A 200A solar photovoltaic DC combiner box

The solar photovoltaic DC combiner box is a device that gathers the DC power generated by photovoltaic panels and transmits it to the centralized inverter for conversion. Its main role is to carry out current distribution and protect the connection between photovoltaic panels.
Solar photovoltaic DC combiner box generally includes the following main parts:
DC input terminal: used to connect the DC power generated by the photovoltaic panel. Depending on the number and power of photovoltaic panels, there may be multiple DC input terminals.
DC output terminal: used to transmit the DC power in the combiner box to the centralized inverter for conversion. Generally, there will be one or more DC output terminals.
Circuit breaker or fuse: used for overcurrent protection to prevent photovoltaic panels from generating excessive current and damaging equipment.
Insulation monitor: It is used to monitor the insulation condition between photovoltaic panels, once an insulation fault is found, an alarm signal will be issued.
Grounding protection: Set the grounding wire in the combiner box to protect the equipment from lightning and overvoltage.
Temperature control: According to the temperature inside the combiner box, temperature control and protection are carried out to prevent the equipment from overheating.
The selection and design of solar photovoltaic DC combiner boxes need to consider the power, quantity, current and voltage requirements of photovoltaic panels, as well as environmental conditions, safety regulations and other factors. Proper selection and use of solar photovoltaic DC combiner boxes can improve the efficiency and reliability of photovoltaic power generation systems.
