The solar powered rapid shutdown transmitter is a device used for the Solar Powered System, mainly used to quickly cut off the power supply of photovoltaic modules or the entire photovoltaic system in emergency situations, eliminate DC high voltage, reduce the risk of electric shock, and protect the safety of equipment and personnel. The quick turn off transmitter detects abnormal conditions in the system, such as high voltage, excessive current, etc., triggering the quick turn off mechanism to reduce the current to zero, thereby avoiding possible safety accidents such as fires and electric shocks, facilitating rescue and maintenance work. It can also be used in some home systems such as Ground Mounting, Flat Roof Mounting, and Metal Sheet Roof Mounting. The input voltage of this product is 12V, DCInput current:0.8A,MaxMppt string voltage:1500VDC。 We can choose based on customer requirements.
