Note: This blog was originally posted in 2020 and was updated in October 2024 to reflect the latest information. AC and DC disconnects are essential components for any residential solar panel system.
Learn MoreThe first step in the disconnection process is to shut off the main power sources. Locate the AC disconnect switch and turn it off. This switch lies between the inverter and the main electrical panel. Find the DC disconnect switch from the PV array to the combiner box or inverter input and turn it off. 2. Cover the Solar Panels
Then ask yourself if where you plan to place the disconnect will in fact disconnect all of the equipment that converts solar energy into electricity, while still allowing the remainder of the connected system to function properly. To fully demonstrate this, let's look at three different examples of PV systems:
1. Turn Off DC and AC Disconnect Switches The first step in the disconnection process is to shut off the main power sources. Locate the AC disconnect switch and turn it off. This switch lies between the inverter and the main electrical panel. Find the DC disconnect switch from the PV array to the combiner box or inverter input and turn it off.
This makes applying correct safety precautions when disconnecting a solar panel or panel array essential. This is particularly true with roof-mounted panels, where an electric shock is often accompanied by a serious fall. If you have a home solar power system, you will probably have to disconnect the solar panels at some point.
It is also helpful in planning upgrades or expansions of the system. The solar panel wiring diagram will typically feature components such as the solar panel, charge controller, battery bank, DC-AC inverter, AC disconnect switch, and other components such as fuses and surge protectors that may be required depending on the specific system.
It's important to note that the integrated DC disconnect on the inverter does not count as a PV system disconnect, since it does not isolate all of the equipment as per the NEC definition – the AC side of the inverter is still connected to the utility load even the DC side of the inverter and the solar panels are disconnected.
