Rapid shutdown for ESS (Energy Storage Systems) batteries

It does also make sense that the battery should also be shutdown, but since in the 2017 NEC, an energy storage system became a separate system from a PV system and rapid shutdown is no longer covering energy storage. Check out 690.12(C)(3) Informational note: "(C) Initiation Device.

6 FAQs about [Switch energy storage disconnection]

Will a solar power disconnect disconnect all of the equipment?

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:

What is an isolation disconnect?

Isolation disconnects may be energized from both directions, such as a DC switch or a fuse between an inverter and a DC-interconnected battery. Isolation disconnects do not have to be readily accessible. Those devices that may remain energized in the open position shall be properly labeled, per 2017 NEC 690.13(B) and 2020 NEC 705.20.

Can I Disconnect a storage system without a break-bolt or plug-in?

Non-load break-bolted or plug-in disconnects are permitted. Another aspect to an ESS is the storage system maintenance disconnecting means.

What is an ESS equipment disconnect?

An ESS equipment disconnect should be able to de-energize the equipment from all power sources and monitor that the system stays de-energized as long as needed. Source disconnects isolate power production equipment from the remainder of the premise wiring.

What is a load disconnecting system?

Disconnection means is an important consideration with these systems. This information is found at 706.8 (A). It is crucial that the load disconnecting means serving multiple sources of power disconnects all energy sources when in the off position. This helps to ensure worker safety, as well as the safety of the equipment and the structure.

Does an integrated DC disconnect count as a PV system disconnect?

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.
