How to connect the inverter to the circuit breaker and remove the back of the panel

Posted Date: 2024-01-26

No matter what inverter you use, you should consider watt capacity, AWG wire size, wire amp rating, and continuous wattage. Amp ratings tell you how much current a wire can safely handle, while continuous watts refer to the voltage loss from the battery to the inverter.

How to connect the inverter to the circuit breaker

Circuit breakers are necessary to protect against overloads, among other uses. Without a circuit breaker, the wires between the battery and inverter are a potential fire hazard.

Another benefit of a circuit breaker is that it works well in solar powered homes. Once installed, you can connect appliances and electronic devices to power sockets and use them.

If you are installing a solar system for your home, make sure the distance between the solar panels and batteries is correct. Once your solar system is ready, you can connect the inverter to the circuit breaker.


If you want step-by-step instructions, follow this.

first step

Turn off the main power switch on the inverter and circuit breaker. The switch is located in the center of the panel, near the top.

Step 2

Remove the screws from the circuit breaker front panel. Select the circuit to which you want to connect your solar panel system. You will be connected to the inverter. Use a screwdriver to remove the back of the panel.

third step

Connect the wires to the inverter output. Before doing this, you must determine two things. First, the inverter is designed to work with a circuit breaker, and second, the wires are the correct size.


Most inverters run fine with a circuit breaker, so this shouldn't be a problem. Check the inverter manual for recommended wire sizes. This will depend on the ampere capacity and inverter voltage.

the fourth step

Once the wires are connected, you should test them. Take a voltmeter and place its probe on the bus bar. If there is voltage, check the circuit breaker as it may still be running.

If the circuit breaker is open but there is still rated voltage, call an electrician because the power is coming from somewhere. However, if there is no voltage, continue to step 5.

the fifth step

Strip a half inch from the insulation covering the ends of the inverter wires going into the circuit breaker. Look for the neutral ground in the circuit breaker and connect the white wire. Connect the hot wire (black or red) to the circuit breaker of your choice.

Place the screws back on the circuit breaker panel. Turn on the circuit breaker main power. Turn on the inverter. Now you can test the outlet plugged into your solar configuration circuit.

The instructions in this article assume you have experience working with electrical wires. If you don't know, hire an electrician to do it for you. Inverters have many safety features and installation is simplified, but the risk of handling power and wires is always present.

This applies not only to inverter installation, but also to connecting the inverter to the mains. As shown here, this requires the use of a circuit breaker. If you're not sure what to do, consult an electrician.
