DC junction box, suitable for both residential and industrial/ commercial photovoltaic systems, providing one-stop protection for the safe operation of the photovoltaic system.
When the PV grid-connected power is 1KW, the required wire number is 2.5mm2; when the PV grid-connected power is 3KW, the required wire number is 4mm2; when the PV grid-connected power is 5KW, the required wire number is 6mm2. In addition, the PV grid-connected power is also related to the length of the cable, and when the length of the cable is more than 50 meters, the wire number needs to be increased in order to ensure the normal operation of the system.
Expansion is limited by the number of strings the combiner box can handle; for more than four strings, additional combiner boxes or a larger one may be needed.
Input: 4mm² (12 AWG) PV cable per string Output: 6mm² (10 AWG) PV cable per output
