EASY FV WALL Remote Disconnect Modem

EASY FV WALL Remote Disconnect Modem

Cod.: TL.033.001 + -
(Included power supply and antenna)

Remote GSM/GPRS disconnection compliant with AEEG 421/2014 CEI 0-16 attachment M

The EASY FV Wall device complies with the requirements of the decree of the Authority for Electricity, Gas, and Water Systems, aimed at ensuring the safety of the national electrical system. The decree mandates the installation of a remote control system for disconnection, managed by the network owner, for power generation facilities (such as photovoltaic, wind, or cogeneration) with a capacity equal to or greater than 100 kW. EASY FV Wall can be directly connected to the SPI interface and, through the pre-established remote commands compliant with the directive, can perform disconnection and remote diagnostics.

Remote Control

  • Activation/deactivation of Digital Outputs (DO) via SMS with AEEG 421/2014 CEI 0-16 compliant protocol
  • Sending the status of Digital Inputs (DI) via SMS with AEEG 421/2014 CEI 0-16 compliant protocol
  • Requesting the system status remotely via SMS
  • Management of the list of enabled Caller Line Identifications (CLI) (up to 50)
