Photovoltaic sensor:Module-level monitoring Module-level monitoring provides the most precise and detailed information on the performance of solar power system, it helps to identify module problems such as partial shadings, PIDs or blown diodes. With such solution, O&M teams are able to save their fault-finding time and increase maintenance efficiency. The sensor unit is the core component of the NxSensor system, it is a MLPE (Module-Level Power Electronics) device that can be integrated into different forms of solar panel’s junction box or add-on/retrofit box, and it continuously measures voltage and temperature of the associated PV module. Besides monitoring, the sensor unit also supports modulelevel rapid shutdown functionality, complying with NEC 2017 690.12 RSD requirements. Key Features • Enable solar PV module-level monitoring; • Enable solar PV module-level rapid shutdown; • Wireless connectivity for module-level communication; • Assign digital ID and RF-based solar panel management; • Compact size, various forms of junction box supported; Benefits • Monitors the voltage and temperature data of each module, giving insight into module-level performance with unprecedented granularity. • Identifies erroneous connection and associated electrical arcs in the junction box, which helps to improve the reliability and safety of a system. • Complies with rapid shutdown requirements of 2017 NEC 690.12, ensuring the safety of system installers, operators and emergency responders. • Modules send data to a gateway using a wireless mesh network architecture – HOHWave®, it is a lowcost and extensible communication system.
