Product FAQ
What are the main functions of PV Grid-Connected Cabinet-Three-Phase?
PV Grid-Connected Cabinet-Three-Phase is mainly used in three-phase photovoltaic grid-connected systems. It collects the DC power of multiple photovoltaic modules and provides necessary protection functions, such as overvoltage protection, lightning protection, and circuit breaker protection. It is an important part of the system.
What are the input and output parameters of PV Grid-Connected Cabinet-Three-Phase?
The input side can connect multiple photovoltaic strings. The typical input voltage range is 200-1000V, and the maximum input current of a single channel can reach 20A; the output side is connected to the inverter. The typical rated output voltage is 380V, and the rated output current depends on the specific model.
What are the requirements for the installation environment of PV Grid-Connected Cabinet?
It should be installed in a ventilated and dry place to avoid direct sunlight and rain. The ambient temperature is usually required to be -25~+60℃. The mounting bracket must be reliably fixed and kept at a certain distance from the building.
What are the cable introduction methods?
Cables can be introduced through holes at the bottom or side of the box, and equipped with waterproof connectors or cable glands. Cable troughs, junction boxes and other accessories can also be selected to achieve flexible wiring. The cable bending radius should not be too small.
What other factors should be considered when selecting?
In addition to electrical parameters, attention should also be paid to protection level, heat dissipation method, installation method, etc. A 25% margin should be reserved during design. Choose well-known brands and compare factors such as certification and after-sales service. Customization is possible if necessary.
