Rapid Shutdown Devices and Risk Reduction in Rooftop Solar Power Systems According to EIT Standards

The 2022 Engineering Institute of Thailand (EIT) standard for rooftop solar power systems in Thailand mandates that rapid shutdown devices be installed, particularly to reduce voltage within the array boundary to no more than 80 volts within 30 seconds. This requirement has led to a significant transformation in the solar power industry in Thailand, especially for solar power systems ranging from 200 kW to less than 1,000 kW, which are exempt from requiring an energy business license but must apply for a controlled energy production permit.
