Litemeter Modbus Pro

Irradiance from 0 to 1600 W/m² at ±5% (±2.5% at STC, 25 °C), and temperature from −30 to +85 °C at ±1.0 °C. Response time is under 100 ms.

The irradiance value is not temperature-compensated.

A monocrystalline silicon cell laminated in glass, covering the 0.3–1.1 µm spectral range in which PV modules produce energy.

Each unit is calibrated against a reference cell that is periodically calibrated by the ISFH institute, following IEC 60904-2, -4 and -10.

12–30 VDC, over a 2.5 m shielded cable that is UV and high-temperature resistant.

Red: +12–30 VDC. Black: 0 VDC. Green: RS485+ (B). Green/white: RS485− (A). Black-blue: ground.

Node address 60, 19,200 bps, 8N1. The address (1–247), bitrate (9,600–115,200 bps) and parity can be changed.

98 × 55 × 25 mm, or 112 × 55 × 66 mm with the mounting bracket, and 304 g.

It has an anodized aluminium housing rated IP65 and a bracket with a screw clamp.
