Sensors & Options

Ambient Air Temperature
Housed in a passive solar 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.

Installation

The PVMET-150's compact, lightweight design makes installation quick and easy. Various mounting options are available, including the RainWise 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, communications and external BOM sensors. Removing the front cover accesses the connections. The cover is secured with 4 screws.

Customization

The firmware in the PVmet™-150 can be updated through the RS-485 port using a simple PC application. This feature ensures that the PVmet™-150 can be kept up to date with the latest available firmware. In addition, RainWise can provide certain OEM firmware customization. This includes register configuration, specific defaults and protocols.

The PVmet™-150 can also be customized to support customer specific sensors. This service is only available to volume OEM customers.
