PV rapid shutdown is one of the important safety equipment of distributed solar system, its role is to protect the life safety of firefighters and maintenance personnel when the solar building needs maintenance or fire rescue. Prevent the danger of electric shock. Fonrich New Energy Company has been exploring this product since 2016. After five years of exploration and practice, the final product has finally come out...
A photovoltaic rapid shutdown system (PVRSS) provides a means for firefighters to stop or reduce the voltage from the PV array, so they can stay as safe as possible from electrical hazards while still doing their jobs efficiently.
Starting in 2014, the U.S. National Electric Code® (NEC®), also known as National Fire Protection Association 70® (NFPA 70®), added Sec. 690.12. This section included requirements for PV rapid shutdown (PVRS) functions to be installed on buildings where PV arrays are installed. PVRSE / PVRSS requirements also appear in the 2017 NEC.
These requirements were intended to reduce the firefighter electric shock hazards posed from energized PV array conductors located outside the array boundary. NEC Sec. 690.12 defined which conductors had to be controlled, the allowable voltage and the allowable maximum time to reach that reduced voltage. The NEC required that equipment performing these new rapid shutdown functions “shall be listed,” but at that time there was no safety standard addressing rapid shutdown equipment or systems implementing this function.
Fonrich PVRSS with monitoring contains:
Controll box, or some other box includes:
The main components in this box are "Head Module" and "Controller"
The left is Head Module, and the right is Controller. The Controller is also the cloud gateway.
Fonrich all repply mobile app to config installation, remote monitoring and data analytics.
The controller can be used as IoT gateway to integrates more features and connects more devices in field.
