Introduction
The PV -100-2 weather station is a compact and economical solution designed to
MET
monitor the efficiency of photovoltaic installations. It measures ambient air temperature,
PV panel temperature and either global or plane of array irradiance. The PV -100-2 is
MET
Sunspec compliant and uses a 2-wire half duplex serial port for Modbus communication
to a host.
Unpacking the System
When unpacking the system the following components should be located.
A1102 – PV -100-2 Sensor Assembly

If the system was ordered with any accessory, it
should be located while unpacking the system. The
available accessories for the PV -100-2 are listed
MET
below.
A2101 – PV Cell Temperature Sensor
A3000 - Mono-Mount
A3010 – Tripod Galvanized Steel
If any of the components are missing, RainWise Inc.
should be contacted.
Installing the Weather Station
It is suggested that you operate your system at ground level and make sure that all
components operate properly prior to installation.
If any of the components are damaged or malfunctioning upon receipt, RainWise should
be contacted.
Site Requirements and Considerations
Ambient air temperature and global irradiance can be affected by obstructions and local
topography. Each site is different and presents challenges in its own unique way. Any
object, in excess of 10 degrees above the plane of the irradiance sensor, must not block
the sensor. The PV -100-2 sensor assembly, which contains the ambient air
MET
temperature, should be no closer than 4 times any obstruction's height and should be
placed away from any dark, heat-absorbing surface.
When roof-mounting the sensor assembly, the unit should be mounted toward an edge of
the roof preferably on the prevailing wind side of the building and should be at least 2 1/2
feet above the roofline. Avoid locating the station near any heat sources such as chimneys
or vents.
