RDE300i PV Module Measurement System

Reference: RDE300i

In-line I-V measurement system for photovoltaic modules, with built-in applications for irradiance, soiling and more.

The RDE300i™ takes PV system performance monitoring to a whole new level: it lets you see inside your array with in-situ I-V data and automatically calculates PV module performance metrics.

Overview

Highlights

Each RDE300i unit measures I-V data, including power (Pmax), current (Isc, Imp) and voltage (Voc, Vmp), on the connected PV module, whether stand-alone or within your PV array.
For in-situ operation, the RDE300i is connected in line with your PV string and performs periodic I-V sweeps without affecting your inverter, removing the need for separate reference modules.
Use the RDE300i to automatically calculate the effective irradiance of the PV reference module, such as total irradiance for bifacial systems, or to monitor the system's potential maximum power output.
By combining several RDE300i units and/or additional Atonometrics sensors through the included AUX port, you can automatically calculate PV module soiling ratios and other performance metrics.
Designed to work with a wide range of PV module types, crystalline or thin-film, bifacial or monofacial. It has a wide input range and can measure up to 30 A, 250 V and 1500 W.
Connects easily to your SCADA system, delivering output data over the Modbus RTU protocol on RS485.
Meets the requirements of the IEC 61724-1 standard for soiling measurement.
Awarded best BoS (Balance of System) sensor by PV Magazine Global.
