Smart module to calculate power, compare string performance, etc.

Description

STM is smart analyser that supports up to 32 channels. Designed specifically to supervise photovoltaic strings, the STM allows for the maximum performance of the photovoltaic array thanks to its high measuring accuracy.
The solution consists of different modules:
STM-C: Smart module that is able to calculate powers, compare string performances, detect reverse currents, etc. It also features:

• One 1,500 VDC input
• Four voltage-free digital inputs
• One analogue input 0/4...20 mA
• One input for Pt100 or Pt1000
• A LoRa wireless communications module

STM-S: Current measurement module with 4 measurement channels of up to 42 A each. Up to 8 
STM-S modules can be connected to obtain 32 channels.
Its modularity, flexibility of installation, smart characteristics and robustness make the STM the perfect piece of equipment to supervise the correct operation of the photovoltaic array.
