What are the different types of rapid shutdown switches?

There are two main types of rapid shutdown switches: String-level rapid shutdown switches de-energize the entire string of solar panels. Module-level rapid shutdown switches de-energize individual solar panels.

Which type of rapid shutdown switch is right for us?

The type of rapid shutdown switch that is right for you will depend on the size and type of your solar panel system. If you have a small system, a string-level rapid shutdown switch may be sufficient. However, if you have a large system or a system with microinverters, you will need a module-level rapid shutdown switch.

Product Q&A

Q:What is a solar rapid shutdown switch?

A solar rapid shutdown switch is a safety device that quickly de-energizes a solar panel system in an emergency. This can help to protect firefighters and other personnel working near the system from electrical shock.

Q:Why is a rapid shutdown switch required?

Solar panels can generate electricity even when the inverter is turned off. This is because the panels are still exposed to sunlight. A rapid shutdown switch helps to ensure that the panels are completely de-energized in an emergency, making it safer for people to work around them.

Q:Where is the rapid shutdown switch located?

The rapid shutdown switch is typically located near the solar inverter. It may be mounted on the wall or on the inverter itself.

Q:How do I use the rapid shutdown switch?

To use the rapid shutdown switch, simply flip the switch to the 'off' position. This will de-energize the solar panel system.

Q:What are the benefits of using a rapid shutdown switch?

The benefits of using a rapid shutdown switch include: Increased safety for firefighters and other personnel working near the solar panel system, Reduced risk of electrical shock, Compliance with NEC 2014 and later.
