MTM-PV module

MTM-PV module

WEATHER MEASURES PERIPHERAL MODULE

MTM-PV weather module is able to perform the following measures:

  • Sun radiation from external silicon cell positioned on the same plane as PV panels (range 0 | 1500 W/m2).
  • Sun radiation from external silicon cell positioned on horizontal plane (range 0 | 1500 W/m2).
  • Temperature of PV panel, from digital probe located behind the panel (range -40°C | +100°C).
  • Environment temperature from digital probe (range -40°C | +70°C).
  • Wind speed (50 m/s max) from external anemometer (pulse output).

The weather module MTM-PV is installed near to the PV plant to ensure valid signals not corrupted from disturbances.

To guarantee high accuracy in sun radiation measurement, it is possible to preset the module with the calibration parameters of the used reference cell.

The module is arranged in an IP66 enclosure.
It is powered directly by E2M-PV module, which is connected to via a RS485 bus over Modbus RTU protocol.

The E2M-PV module is able to manage up to two distinct MTM-PV modules.

The environment and panel temperature probes are supplied with the MTM-PV module, while the other probes
(cell irradiation, pyranometer, and anemometer) are supplied optionally.
