Per NEC Article 100, a "PV system" is defined as "The total components and subsystem that, in combination, convert solar energy into electric energy for connection to a utilization load." In accordance with this
The system interactive inverter output circuit conductors can be connected on either the supply side or the load side of the service disconnect [Sec. 705.12]. If you connect the PV system interactive inverter output circuit conductors to the supply side of the service disconnect, follow Sec. 230.82(6).
A permanent plaque or directory shall be installed at each service equipment location, or at an approved readily visible location. The plaque or directory shall denote the location of each power source disconnecting means for the building or structure and be grouped with other plaques or directories for other on-site sources.

That disconnect does isolate the PV power source from the rest of the system but it does not isolate all of the PV equipment. The DC disconnect will stop the inverter from producing power but the AC side of the inverter will still be connected to the utility.

Also known as the electrical infrastructure and equipment from the utility connection onsite to the inverter(s). The three most commonly cited requirement categories for AC disconnect placement are the following: equipment service, safety for firefighters, and utility operation. The first of which is the California Electrical Code.
Any structure containing both utility service and a PV system must have a permanent plaque identifying the location of the service disconnect and PV system AC disconnect (if they are not at the same location) [690.56(B)]. Connection to other sources. For interactive systems, use only inverters and AC PV modules listed as interactive [690.60].
In this system, the PV disconnect is positioned on the AC side of the interactive inverter, similar to the grid-direct example above. Once more, let''s confirm: Am I disconnecting all the equipment required to convert solar energy into electric energy?
EXPLANATION: 690.12(C)(1) was revised to remove the option for the label, previously listed under 690.56(C)(1)(b), since this label describes a shutdown method that is no longer code compliant in NEC 2020. When rapid shutdown was first published, the panel established a timeline for compliance, which has now passed. Since all installations are now
The service disconnecting means must be identified as suitable for use as service equipment [230.66]. This means the service disconnecting means is supplied with a main bonding jumper so that a neutral-to-case connection can be made, as

The NEC690 Building Inspector''s Guide is a set of reference materials developed for Building Inspectors and AHJ Officials as it relates to Article 690, of the National Electrical Code (NEC 2014) for Photovoltaic Warning Labels.
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.
Where a PV System operates in parallel with the electric utility as permitted by Article 705, a permanent plaque, label, or directory must be installed at the service disconnect location per 705.10 [690.56]. PV systems connected in parallel with the electric utility must have the interconnection made per Article 705 [690.59]. Coming up next
A directory identifying the solar system and other power sources on site should be placed at service equipment and state the location of system disconnecting means if not at the same
The two to six disconnects as permitted in 230.71 shall be grouped. Each disconnect shall be marked to indicate the load served. 230.71 Maximum Number of Disconnects How a PV system can be interpreted as a service (A) General.
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.
