Solar Array Junction Box
08th Feb 2022
If you’re looking to install solar panels on your roof, you’ve probably wondered about Solar Array Junction Box. The combination box is an outdoor-rated enclosure that connects several solar panels together. It features positive and negative bus bars, and a strain relief wire fitting serves as a wire pass-through point. In a solar array, there are usually six solar panels connected in two parallel strings of three panels each. Each string includes a Positive and Negative connection cable, a breaker, and a strain relief wire fitting. The best junction box for your system should be rated for 1000 V DC and 225 Amps. It should also be rated for UV and IP65 protection. The junction box will come with two options for cable entry. You’ll need to choose the cable gland or MC4 connector.

It is designed to protect wires from sunlight, moisture, friction, and critters. The junction box is usually located near the array site and should be insulated against all of these factors. In addition to protecting the components in your Solar Array, it will also protect your home from critters. If you are constructing a solar PV array, one important component is the array junction box. These boxes connect the output leads of the solar PV modules to the strings connected to the combiner box.
