Product FAQ
What should be noted when installing PV Combiner Box-Steel Box Type?
Please read the instructions carefully before installation to ensure that the installation location is away from direct sunlight and rain, and is convenient for subsequent maintenance. Please disconnect the photovoltaic string first when wiring, and do a good job of waterproof sealing. Make sure that the box is reliably grounded during installation.
How to correctly select the specifications and models of PV Combiner Box-Steel Box Type?
It is necessary to consider factors such as the voltage level of the system, the short-circuit current of the photovoltaic module, the number of input and output circuits, and reserve a certain margin. If necessary, consult professionals to assist in the selection.
What are the cable introduction methods?
Cables can be introduced through holes at the bottom or side of the box, and waterproof connectors or glands can be provided. Cable troughs, junction boxes and other accessories can also be selected to achieve flexible wiring.
What is the anti-corrosion treatment process of the steel plate shell?
It adopts high-quality spraying technology with excellent anti-corrosion and weather resistance. Some models can also be made of stainless steel, which is suitable for corrosive environments such as the seaside.
What maintenance matters need to be paid attention to in daily use?
Check the sealing of the shell regularly to ensure that the fasteners are reliable and not loose. Check the internal terminals and conductive parts to ensure there is no abnormal phenomenon such as heating, discoloration, etc. If a fault is found, please contact a professional immediately and do not operate with power on.
