The DC output of the combiner box can be shut down through the internal circuit breaker. The following requirements should be met before commissioning: 1. Check for any debris on the busbars and equipment. 2. Gradually check if the internal wiring of the solar combiner box is correct.
Wall-mounted: It is recommended to use expansion screws to fix it on the wall through the mounting holes on both sides of the solar combiner box. Pole-hugging: It is recommended to use clamps and angle steel as support brackets, and install the combiner box on them with screws. 1. Precautions for Solar Combiner Box Electrical Installation
Cable entry device or conduit entry port: These openings allow cables from the strings of solar panels and output cables to enter the combiner box while maintaining waterproof sealing. Peel off the outer sheath of the cable. Wear during installation. How are the components of the photovoltaic combiner box installed?
Ensure the circuit breaker is in the “OFF” or “TRIP” position (or the load isolation switch is in the “OFF” position) to disconnect the combiner box from the PV DC output side. All fuse holders inside the combiner box should be open (or remove the fuse core using specialized pliers) to disconnect the DC combiner box from the PV string input side.
2.2 The general cooling method for PV combiner boxes is natural cooling. To ensure the normal operation and service life of the combiner box, try not to install it in areas with direct sunlight or excessively high ambient temperatures.
