QC Solar launches Smarttrack04, a new generation of Module-Level
Rapid Shutdown Devices that comply with CSA C22.2 No. 330 and UL1741. In the event of an emergency or maintenance, this device can quickly reduce the system voltage to a safe level within 30 seconds, quickly reducing the voltage of each connected PV module. This eliminates the dangerous DC high voltage present in the PV system and reduces the risk of electric shock.
- 01. SMOJ (preinstallation of PV modules) solutionsFixed housing, providing further convenient installation, can be adapted to any PV modules production line, to realize the PV modules factory preinstallation, without affecting the existing PV modules all the test procedures (IV, EL, etc). It does not change the on-site installation habits and saves the labor cost of traditional metal clips installation, saves 50% labor, approx. 20 EUR. The fixed seat mounting method saves 1.5m of wire harness, approx. 0.65 EUR. Quick dismantling during the whole life cycle.
- 02 Frame Snap SolutionSnap-on mounting directly to the PV modules frame, suitable for EPC installation.
Manufactured with quality in mind
Smarttrack04 uses low-temperature rise and high-temperature-resistant power semiconductor devices to ensure long-term stable operation in extreme environments, supports the full voltage range, does not derate, and supports 1.25 times current redundancy, provides 20A/25A for customers to choose, and can be widely used in residential roofs and industrial and commercial roofs.
Currently, the new generation of Module-Level Rapid Shutdown Devices Smarttrack04 independently developed by QC Solar has obtained international authoritative certifications such as CSA and conforms to UL 1741. CSA C22.2 No. 330 and NEC-2017/NEC-2020/NEC-2023 electrical safety and regulatory standards, and complies with the Sunspec communication protocol. Provide more protection for household and commercial photovoltaic field.
Residential PV systems
In home PV systems, PV rapid shutdowns are used to quickly reduce the voltage below a safe voltage in case of an emergency such as a fire, to safeguard the family.
Photovoltaic power stations
In power stations, PV rapid shutdowns are used to quickly reduce the voltage below the safe voltage in the event of a fire, reducing damage and safeguarding the surrounding environment.
Commercial building PV systems
PV systems are usually installed on the roof, and the rapid shutdowns are able to reduce the voltage to below the safe voltage in case of failure or other emergencies, to protect personal safety.
