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.
