Outdoor Photovoltaic Fire Safety Switch With Roof Solar Power Generation

Photovoltaic New Energy Roof Outdoor Solar Power Generation FirefightersPower Generation

Why do photovoltaic systems need to be quickly shut down?

Photovoltaic power plant fire easy, rescue difficult.

In high voltage photovoltaic systems, module hot spots, cluster mismatches, broken cables, tight connections and inverters

Ash accumulation and other problems can easily cause fire in photovoltaic power stations. Photovoltaic power station operation and maintenance time is 25 years, with the passage of time

Equipment aging, accident probability increases exponentially. However, in the event of a fire, only turn off the inverter to power

For the ac of the network, there are hundreds or even hundreds of DC sides between the components and between the components and the inverter

Thousands of volts of high voltage, if the firefighters rushed to rescue, will be a threat to the life of firefighters. In this case,

Let it burn.

A quick shutdown can cut off the current between components and the inverter or between components, creating a fire fighter

Safe rescue environment, reduce fire loss, protect personal and property safety.
