SunSpec PVMet150; Weather Station w/CMP3

Product Code: ENG58-SP
Model #: PVMet-150

Made in the USA - The PVMet-150 is a SunSpec/ModBus weather station with an integrated CMP3, preassembled and simple to install.


PVMet-150 Weather Station

Solar Energy Efficiency Monitor

These SunSpec Certified weather stations were designed to meet the needs of alternative energy power generation, specifically solar generation. The PVmet series use Modbus protocols, feature sensors and communication options that provide a powerful add-on to any solar power plant. The PVMET-150 is the intermediate level station option. It features sensors specific to PV power generation. This low cost station is compact and simple to install. As with all PVMET stations it includes a RS-485 Modbus interface.

Entry Features include:

  • Adjustable Solar Irradiance Sensor for Global or Plane-of-Array Monitoring

  • 1 or 2 x Back-of-PV Panel Temp Sensor(s)

  • Ambient Air Temperature Sensor

  • Wind Speed sensor

  • Wind Direction Sensor

  • Modbus RS-485 Communication

  • Ethernet Modbus TCP Option Available

  • Sunspec Ver. 1.1 Option Available

  • Available with Private Labeling for OEM

Sensors & Options:

  • Ambient Air Temperature

  • Housed in a passive solar shield.

  • Global Irradiance

The irradiance sensor is adjustable and can be set to provide global irradiance. A separate plane-of-array sensor is supplied with a mounting bracket to attach to the side of the PV panel.

Sensors & Options:

  • Ambient Air Temperature: Housed in a passive shield

  • Global Irradiance or Plane-of-Array Irradiance: The irradiance sensor is adjustable and can be set to provide global irradiance (when horizontal) or plane -of-array irradiance when installed to match the PV panel angle.

  • Back-of-Module Temperature: These sensors are attached to the back of the PV panel using thermal conductive adhesive tape. They provide accurate panel temperatures, an important parameter for efficiency monitoring. One sensor is shipped with each system. The PVMet-150 supports two sensors. The second may be purchased separately.


The PVMet-150 has a single, 2-wire, half duplex, RS-485 port. Termination can be enabled or disabled using a jumper located near the RS-485 screw terminals. By default the PVMet-150 is configured to operate as a Modbus slave at address 60. The Modbus register layout is compatible with SunSpec Ver 1.1.


The PVMet-150 ’s compact light weight design make installation quick and easy. Various mounting options are available, including a 3-foot tripod and Mono mount. The PVMet-150 is supplied with a detachable mast section that can bolt 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 communications and external BOM sensors. Connections are accessed by removing the front cover. The cover is secured with four screws.
