Irradiation Sensor

LiteMeter modbus

LiteMeter modbus is a low-cost photovoltaic pyranometer.

Irradiation SensorDesigned in accordance with the IEC 60904 and later, the Litemeter MODBUS is quick and easy to install and compatible with the most part of data-logger on the market.

Litmeter MODBUS is born from the Sunmeter experience and it is like its simplification. Litemeter is less-precision of sunmeter and it is perfect for the monitoring of small and medium photovoltaic system.
The output signal is only digital. Litemeter is equipped with a temperature sensor input for photovoltaic modules. It’s a tool of great potential, essential for a good monitoring and management of your system.

Calibrated by stabilized silicon Reference Cell referenced by Fraunhofer Institute (DE).

Key Features:

  • Monocrystalline silicon cell
  • RS485 Modbus RTU standard protocol port to ensure the readings even at 500m from data logger
