Product Details

Gain remote visibility and control over your 48-volt or off-grid power system with the Victron GlobalLink 520. As your gateway to Victron’s Web-based Remote Management (VRM) portal, this device connects your VE.Direct-enabled equipment and compatible Smart devices via LTE-M cellular or Bluetooth, helping you monitor battery health, power flows, alarms, and more without needing Wi-Fi or external routers.

Key Features

  • Built-in 4G LTE-M connectivity – uses minimal power, robust for remote, mobile or off-grid setups. First five years of data and connectivity are included, no monthly fees.
  • VE.Direct ports (x2) – allows for hard-wired connections to two VE.Direct devices such as battery monitors or MPPT charge controllers.
  • Bluetooth support for Smart devices & RuuviTag sensors – monitor temperature, humidity, pressure, or instant-readout from compatible Victron Smart devices via BLE.
  • Digital inputs & relay – two digital input channels that also act as pulse counters; relay (NO/NC) for remote control via VRM.
  • Wide input voltage range – powered from 8 to 70 V DC, suitable for battery banks and off-grid configurations.
  • Energy-efficient operation – very low power draw, especially at higher DC voltages; designed to minimise load on connected systems.

Applications

Ideal for off-grid solar systems, marine or RV installations, remote cabins, or any setup where continuous monitoring of batteries, inverters, solar harvest or system faults is critical. The GlobalLink 520 ensures you can assess performance, diagnose issues, and receive alerts from wherever you are.
