About the GlobalLink 520 Remote Monitoring System

We believe that having insight into your installation is a key factor in maintaining and operating your off-grid energy solutions. Off-grid should not mean off-line, so we have created the GlobalLink 520. This device will bring 4G LTE-M connectivity to all VE.Direct enabled devices without any monthly fees or subscriptions, for the first five years.

Global connectivity with 4G LTE-M

LTE-M is the abbreviation for LTE Cat-M1 or Long Term Evolution (4G), category M1. This cellular technology is designed to connect Internet of Things devices to existing 4G towers while using low energy. LTE-M does support handovers and roaming so it is possible to use this device in a moving vehicle like a campervan. Check the list in our GlobalLink 520 manual to see if LTE-M is officially confirmed to be available in your area. Coverage is increasing every week as local providers roll out support. Your purchase includes 5 years of connectivity, so there is no need to worry about purchasing a separate data bundle and SIM-card.

System monitoring & control

The GlobalLink 520 comes with two communication ports, which allows connecting up to two VE.Direct devices such as a BMV Battery Monitor and/or a MPPT Solar Charge Controller directly to VRM. With two digital inputs that also act as pulse counters and a remote controllable relay, it's a perfect solution to monitor and control your installation.

Antenna built in

The GlobalLink 520 comes with a built-in antenna that is designed to work all around the globe. However if you require better reception or want to install your module in a utility van for example, it is also possible to mount an external antenna.

RuuviTag Support

The GlobalLink 520 now supports the RuuviTag temperature sensors. These battery powered sensors connect via BLE and are easy to setup via VictronConnect. All the data, like temperature, humidity and air pressure from the RuuviTag sensors, will directly be available in VRM.

Victron Remote Management

The online Victron Remote Management (VRM) portal provides you with access to your installation, from anywhere, at any time. In VRM you can check the status of your connected products, view detailed history graphs of your energy, generate detailed analytical reports, and even configure automatic alarms in case something goes wrong.

The GlobalLink 520 connects your remote Victron system or individual products to VRM, our online Victron Remote Management portal. Through that portal, you can monitor current and historical system operation – such as battery voltage and state of charge – from anywhere in the world. VRM is free to use.
Unique is the pre-installed and pre-paid SIM card: the GlobalLink comes with 5 years of 4G LTE-M connectivity.
No need to purchase and maintain SIM-cards.

GlobalLink 520 Features

• Smart device* and VE.Direct support: Connect up to 10 Victron smart products using BLE and two hard wired VE.Direct devices.
• VRM-monitoring: Monitor battery state of charge, power consumption, power harvest from PV, generator and grid or check temperature measurements. Follow up on alerts and perform diagnostics checks.
• RuuviTag support: These sensors connect via BLE and are easy to setup via VictronConnect. All the data, like temperature, humidity and atmospheric pressure will be directly available in VRM.
• Support for custom SIM cards.
• Simple mounting and configuration: The GlobalLink 520 is wall mountable. The Bluetooth feature enables a quick connection and easy configuration via our VictronConnect app.
