High Voltage Quick Switch Roof PV Residential Factory Solar Panel Electric Fire Safety Switch IP65 1500V

Why is quick photovoltaic module level shutdown so important?

There are many reasons for fire in photovoltaic power stations. The equipment with high fire risk includes inverters, bushboxes, cables and components. As long as it is an electrical system, it has the risk of fire due to current. In addition, with the development of photovoltaic technology, the power levels and current voltages of photovoltaic products are constantly increasing. Photovoltaic systems have been upgraded from the original design of 600V to 1000V, and recently gradually to 1500V. Higher voltages are more likely to cause fires. The photovoltaic power plant fire presents a great challenge to the fire brigade. After the system fire, there will still be hundreds or even thousands of volts of high voltage, if the firefighters rushed to rescue, will pose a threat to the lives of firefighters. With the component-level quick shutdown function, firefighters can quickly sever connections between components to rescue the plant.

What is a component-level shut-off?

Component level switcher is a device which can realize component level fast switch-off. In an emergency situation, the device can quickly disconnect the connection between each photovoltaic module remotely or manually, thereby eliminating the DC high voltage in the photovoltaic system array, reducing the risk of electric shock and solving the rescue risk. Benyi electric component-level switcher has many advantages, such as safety and reliability, flexible installation, high efficiency and low noise. Dual channel DC input, greatly reducing installation cost; NEC 2017&2020(690.12), SunSpec certification requirements; Small in size and light in weight, it can be directly attached to the frame of the component or glued to the backplane of the component.
