6 FAQs about [Ul 3741 photovoltaic hazard control]

What is ul 3741 hazard control?

According to the UL 3741 PV Hazard Control statement of scope, the standard “provides a means for evaluation of PV hazard control components, equipment and systems that provide a reduced level of shock hazard from energized PV system equipment and circuits located within the PV array.”

Does ul 3741 apply to PV installations?

Before jumping into the application of UL 3741 in PV installations, let’s take a step back and look at the code requirements driving us to the standard. Section 690.12, Rapid Shutdown of PV Systems on Buildings, is familiar to most PV professionals.

What is UL 3741 Photovoltaic Hazard Control?

UL 3741, Photovoltaic Hazard Control, specifies that controlled conductors located inside the boundary shall be limited to not more than 80 volts within 30 seconds of rapid shutdown initiation. Voltage is measured between any two conductors and between any conductor and ground.

What is the new UL 3741 safety standard?

Underwriters Laboratories, a U.S. nonprofit standards development organization, has published the new UL 3741 safety standard, which is related to the evaluation of PV hazard control functions.

Why is ul 3741 certification important?

If firefighters must access and undertake emergency operations on the roof – whether directly involving the PV array or not – systems engineered to pass UL 3741 certification reduce the risk of firefighters being exposed to life-threatening shock hazards when working around the (potentially damaged) PV array.

How do you pass ul 3741 testing?

To pass the UL 3741 testing, manufacturers must prove that firefighters will not be exposed to shock hazards in various scenarios, including when firefighters fall on PV equipment with tools in their hands. The SMA Sunny Tripower CORE1 is the first free-standing string inverter and the first listed to UL 3741 PV Hazard Control for NEC 690.12.
