6 FAQs about [Photovoltaic inverter often disconnects]

What is a DC disconnect on a solar inverter?

The DC disconnects (sometimes referred to as the PV disconnects) are placed between the solar panels and the inverter or, in many cases, built into the inverter. The inverter is the piece of equipment that switches incoming power from DC (direct current) to AC (alternating current) so that your home can use the power.

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 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.

What is a PV DC disconnect?

The PV DC disconnect refers to a disconnecting means for all ungrounded conductors of a photovoltaic (PV) system as required by the NEC (National Electrical Code). In the 2002-2014 NEC, Section 690.13 and 690.13 (A), this disconnect was to be located at a readily accessible location at or near the point of entry of these conductors into the building.

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.
