ReRa Solutions - PV-Monitor for PV-System Measurement

The ReRa PV-Monitor (PV-MON) is a specialized device designed for the measurement of DC current and voltage within any photovoltaic (PV) string or module. It supports outdoor conditions with its weatherproof design and can be installed behind any PV module without requiring special tools. The PV-MON does not interfere with existing inverters or measurement instruments as it connects seamlessly with the available cabling. This device features two analog inputs for temperature and irradiance sensors and uses a fully isolated digital MODBUS-RTU for communication. Available in two models, PV-MON-LV (200V, 30A) and PV-MON-HV (1500V, 30A), it offers software-controllable voltage ranges and ensures safe operation with 2kV galvanic isolation protecting both sensors and the PV side.
