6 FAQs about [Photovoltaic panel series disconnection]

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 solar DC disconnect switch?

A solar DC disconnect (or PV disconnect) shuts off the direct current (DC) power traveling from the solar panels to the inverter. DC disconnects are often built into the solar inverter. Do I need a solar disconnect switch? Local ordinances and building codes require AC and DC disconnects in all solar installations.

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.

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.

Why do solar panels need AC & DC disconnects?

There are 5 main reasons why AC and DC disconnects are needed on a solar panel installation: AC and DC disconnects are required by local ordinances and building codes.

Where is the AC disconnect located in a solar PV system?

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. The AC disconnect is sized based on the output current of the inverter and will be looked at in depth in a different article.
