Control module for PV measurement using a shunt

Description

STM-S is an intelligent analyser with up to 24 channels. Specifically designed for monitoring photovoltaic strings, the STM-S ensures maximum photovoltaic field performance thanks to its high measurement accuracy. It is equipped with the intelligence to calculate power, compare string performance, detect reverse currents, manage alarms, etc. The device is available in 12- or 24-channel configurations.

Its main features are as follows:

• Voltage input (1.500 V dc)
• Current measurement up to 45 A (12-channel configuration) or 30 A per channel (24-channel configuration)
• 1 input for Pt100
• 3 potential-free digital inputs
• Wireless LoRa communications module

Its compact size, installation flexibility, intelligence and robustness make the STM-S the perfect device for monitoring the correct operation of the photovoltaic field.
