VSN800 Weather Station

Monitoring and communications - VSN800 Weather Station
The VSN800 contains the essential environmental sensor set
needed for solar monitoring. The expanded sensor set allows a
wider monitoring of environmental parameters.
VSN800 is the perfect companion to the VSN700 Data Logger
products and it can directly be connected to the RS-485 port
of the new PVS string inverter families.
Shipped preconfigured and ready for installation requiring no
special tools
The VSN800 Weather Station is delivered ready for installation
and requires the installer to mechanically mount the modules on
a user-supplied mast, connect power and communication, and
initialize the automatic system commissioning process.
No special software, or on-site calibration is required.
The all-in-one weather station reduces the installation, support
and maintenance cost while improving the robustness and
manageability of the PV plant monitoring solution.
The basic sensor set the VSN800-12 model is equipped with
provides data needed to calculate a performance ratio allowing a
plant operator to track solar array performance against expected
energy production.
The advanced sensor set the VSN800-14 model is equipped with
improves monitoring of weather conditions that can affect
energy production. The extra irradiance sensor for mounting at
the plane of the array allows more accurate measurement of
irradiance that is incident in the plane of the solar panels.
The wind speed and direction sensor gives the operator
information about how the wind may be cooling the panels and
some indication of how much dust may be accumulating on the
panels.
Highlights
• Two models offered for basic and advanced sensor sets
• VSN800-12 includes a basic sensor set: ambient temperature,
solar irradiance, and back of module temperature
• VSN800-14 includes additional advanced sensors: plane of
array irradiance and wind direction and speed
• Sensors, data acquisition unit, and RS-485
• Can be connected directly to the RS-485 port of the new PVS
string inverter families.
