The PVmet-500-M4 station is a unique modular platform to configure the most comprehensive weather station. Multiple high end pyranometers and weather sensors can be combined as a turnkey soltion for PV monitoring applications. This low cost station is compact and simple to install and to connect to any inverter or SCADA system. PVmet is an innovative sensor platform for PV monitoring applications, which is developed by Rainwise Inc. and provided by EKO.

PVmet-500-M4 weather station comprises a powerful electronic interface to connect all sensors and convert the output to a Modbus data string (RS-485 Modbus interface – Sunspec® certified).

Standard measurement parameters are

  • PV back-panel temperature
  • Relative humidity
  • Barometric pressure
  • Ambient temperature
  • GHI Irradiance
  • Wind speed and direction (Ultrasonic)
  • Precipitation

Optional parameters are Irradiance (POA, GHI), additional back-panel temperature. EKO offers 5 different pre-configured PVmet-500 systems.

PVmet series are turn-key, easy to install and can be deployed under harsh environmental conditions. EKO provides a unique radiometer calibration compliant to the international standards defined by ISO/IEC17025/9847.

Various mounting options are available, including the Mono Mount. The PVmet is supplied with a detachable mast section that can be bolted to an existing structure.

All electrical connections are made using screw terminals. Standard sensors are factory installed. As a user/installer
the only connections required are power and communication pheriphirals to connect the weather station.
