What is a safety disconnect in a solar PV system?

A solar PV system typically has two safety disconnects. The first is the PV disconnect (or Array DC Disconnect). The PV disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. The second disconnect is the AC Disconnect. The AC Disconnect is used to separate the inverter from the electrical grid.

What is a photovoltaic string disconnect switch?

Photovoltaic string disconnect switches New installations of solar photovoltaic (PV) generation systems have increased the need for disconnect switches and overcurrent protective devices capable of interrupting currents at voltages up to 600 Vdc. This application is covered by NECT Article 690, solar photovoltaic (PV) systems.

What is the second disconnect in a solar PV system?

The second disconnect is the AC Disconnect. The AC Disconnect is used to separate the inverter from the electrical grid. In a solar PV system the AC Disconnect is usually mounted to the wall between the inverter and utility meter. The AC disconnect may be a breaker on a service panel or it may be a stand-alone switch.

What is a PV system disconnect?

The external disconnect, shown as the switch between the inverter and the electrical panel, may not be a Code or utility requirement for the system per your local authority having jurisdiction (AHJ). If that is the case, the breaker in the electrical panel would be considered the PV system disconnect.

What is the difference between AC disconnect and PV disconnect?

The PV disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. The second disconnect is the AC Disconnect. The AC Disconnect is used to separate the inverter from the electrical grid. In a solar PV system the AC Disconnect is usually mounted to the wall between the inverter and utility meter.

Is a DC disconnect considered a PV system disconnect?

The DC disconnect will stop the inverter from producing power but the AC side of the inverter will still be connected to the utility. Therefore this wouldn’t be considered the PV system disconnect as not all the PV equipment is disconnected. Of course, it wouldn’t be Code if there weren’t special cases and exceptions.
