The SP600S allows module-level rapid shutdown, which guarantees a safe DC voltage of the PV power plant throughout its lifespan. During installation, the optimizer keeps an output voltage of 1V in an inactive state, ensuring a safe low-voltage installation process.
During routine maintenance, the module voltage can be lowered to 1V by disconnecting the AC power supply or triggering an external switch, ensuring safety during maintenance. In case of an emergency, such as a fire, the optimizer automatically shuts down relevant modules within 20 seconds, which is 10 seconds faster than the NEC2017/2020 requirement. This reduces the string voltage to below 30V, ensuring the safety of firefighters and minimizing or avoiding losses of the project owner
