Detection of dangers in solar power generation systems: "PV Remote Monitoring System"

Automatically detects the occurrence of "solar cell malfunctions" and "DC ground fault incidents" that lead to fire accidents in solar power generation systems, serving as a safety net!

In solar power generation systems, there is a risk of fire accidents caused by factors such as leakage current and failures of bypass diodes in solar cells. To detect these issues, manual inspection work using devices like megohmmeters and bypass diode testing equipment is necessary. However, this device automatically performs these inspection tasks. It captures changes in conditions that are difficult to detect through monitoring measurement values via power conditioners, significantly contributing to the safe operation of solar power generation systems and the maintenance of power generation capacity. Furthermore, it is an unprecedented remote monitoring device capable of detecting cable theft (disconnection) on the DC side. ◆ Measurement of insulation resistance of solar cell strings (DC ground fault detection and ground fault location identification) ◆ Measurement of bypass routes ◆ Measurement of blocking diodes (reverse current prevention diodes) ◆ Measurement of operating voltage of solar cell strings
