Rapid Shut Down Energy Modules are a protective measure used in the Solar Powered System, while also having a Thai Electrical Code: Solar Rooftop Power Supply Installation 2022 stipulates that the rapid shutdown device must ensure that the voltage drops below 80V within a 300mm range of the PV matrix within 30 seconds after startup. For areas exceeding this limit, the voltage must be reduced to below 30V within the same time period. We have ensured personnel safety and carried out system maintenance. Rapid Shut Down Energy Modules can be used for Ground Mounting or Flat Roof Mounting, as well as for household systems, to protect the entire solar energy system.
