Quick shutdown devices with CE certification

For fire protection of solar roofs and buildings, our string- and module-level fast shutdown devices control the voltage reduction in the panel to a certain safe level within microseconds. Prevent accidents and increase the safety of your solar system.
Our quick disconnect solutions are designed to CE, UL and NEC2020 requirements. As a member of the Sunspec alliance, we proudly develop communication RSDs for PLCs for greater compatibility with multi-string inverters.
