DC Monitoring System for photovoltaic installations with real-time supervision of current, voltage, temperature and component status. Supports up to 32 channels, RS485/PLC communication, optional arc-fault detection and compatibility with 1000V/1700V systems. However, photovoltaic plants need to be monitored and maintained in order to reduce the electricity production costs (levelized cost of electricity/LCOE) of the plants. The inverter independent and easy to use datalogger for every pv installation. monitoring of solar PVs is necessary on both the commercial and residential level, as companies fight to track ROI from green energy initiatives, estimate costs and monitor effectiveness while individual users of solar PVs look to authenticate results and track savings. Simply selecting a current sensor based on a unified standard often fails.
