Technical FAQs 4

Can a solar inverter be turned off without a rapid shutdown device?

Without a Rapid Shutdown device, there is no safe way to turn off the voltage and current running through those conductors for DC-based Solar PV systems. This poses a serious electrical hazard to first responders and maintenance personnel, as DC wiring retains high voltage even when the inverter is switched off.

How do you shut down a solar PV system?

Properly shutting down a solar PV system is a common concern among users. Within the entire system, the AC side can be disconnected via the NFB (no-fuse breaker) on the AC distribution panel.

Is module level rapid shutdown safe in solar power plants?

In the field of solar power generation, safety is always an important and unavoidable topic. With continuous advancements in technology, module level rapid shutdown has emerged as an efficient and safe method, gradually becoming a crucial solution for addressing the safety risks of high DC voltage in solar power plants.

Why do solar PV systems have a rapid shutdown feature?

To prevent this, the National Electrical Code (NEC) mandates the Rapid Shutdown feature to ensure a safer working environment. Traditional solar PV systems are DC-based, meaning they produce direct current (DC) electricity, which remains live as long as sunlight is available.
