How to connect the contactor circuit of solar energy

How do you wire a contactor?

Route the wires. Remove all power to the wires. Run all input and output wires to the contactor. These wires should be rated in the manufacturer information. Use wire strippers to cut excess length off of the ends of the wire, making sure that the wires are long enough to reach the intended contact.

How does a contactor work?

To energize the contactor, a button is pressed. This sends power to the coil. The coil energizes, creating a field that magnetizes the core. The magnetized core attracts an armature. The armature is connected to a set of moving contacts. A high-energy device or system receives power and starts working.

How do I install a contactor?

Strip the wires. Run all input and output wires to the contactor. Acquire the contactor. Make sure that the contacts of the contactor are rated in both voltage and current to handle the expected load that will be required by the equipment being powered.

How do solar interconnections work?

If you are new to solar, this article by Solar Power World about interconnections is a helpful startingpoint. In this configuration, the meter is physically separated from the main breaker which exposes conductors on the line side that can be accessed. This gives us a lot of options for solar interconnection methods.

What are the parts of an alternating current contactor?

Insides the alternating current contactor are parts that make its working possible. These mainly include the following: coil and its core (electromagnet), power and auxiliary contacts, terminals, and the enclosure or housing. The AC contactor coil is responsible for creating the magnetic field that causes movement and the closing of power contacts.

How do I wire a solar system?

The solar system max output must be less than the main circuit breaker rating of every connected unit. The neutral for the SolShare must be wired directly to the main neutral bar inside the main switch-board, i.e. at the Main Earth Neutral link at the building’s main switchboard.
