6 FAQs about [Photovoltaic panel step-down device]

Do I need a rapid shutdown device for a photovoltaic system?

According to the National Electrical Code (NEC) Article 690.12, rapid shutdown devices are required for photovoltaic (PV) systems installed on buildings. Specifically, they are needed when PV systems are installed on buildings where the voltage between any two conductors does not exceed 80 volts during normal operation.

How do I reduce the voltage from a solar panel?

There are two ways to reduce the voltage from a solar panel. Those are: 1. Connect the panel to something that requires charging; A lead-acid battery will take the energy from the solar panel, leaving it depleted so long as the panel is not in the sun. Under this example, you are literally removing the voltage from the solar panel.

What types of solar modules can be used in a rapid shutdown?

BENY rapid shutdown solutions accommodate all types of solar modules, available in both module-level and string-level. Regardless of the choice, we ensure that our products comply with NEC standards and specifications. – industrial sites/large public buildings/large scale solar famms.

Which PV systems are exempt from rapid shutdown requirements?

Ground-mounted PV systems: Systems mounted on the ground and not located on or in buildings may be exempt from rapid shutdown requirements. PV systems with microinverters or AC modules: Rapid shutdown may not be necessary for systems that use microinverters or AC modules that automatically de-energize when the AC power is shut off.

Do inverter systems comply with module-level rapid shutdown?

Some inverter systems inherently comply with module-level rapid shutdown (NEC 2017 and later), while others require additional components to enable rapid shutdown.

Do solar panels need a shutdown boundary?

Newer regulation, NEC 2017, takes these standards a step further: the more recent code decreased the shutdown boundary requirements to include any conductors within 1 foot of your solar array or more than 3 feet of length inside your home.
