Photonic Universe is an official distributor of products from Victron Energy – the globally renowned manufacturer of high-quality hybrid power electronics. Victron Energy products have a longstanding reputation for their outstanding reliability, innovative design and superior build quality.

The GlobalLink 520 is Victron Energy’s dedicated plug-and-play remote monitoring solution for VE.Direct-enabled devices. Designed to keep your off-grid energy system connected at all times, the GlobalLink 520 brings 4G LTE-M global connectivity without any monthly fees or subscriptions for the first five years. This compact and efficient device enables seamless real-time monitoring and control of your Victron system from anywhere in the world through the Victron Remote Management (VRM) portal.

Whether in a static off-grid setup, a mobile campervan, or an industrial installation, the GlobalLink 520 ensures you stay informed and in control—no matter where your system is located.

Key features:

• Always online, even off-grid: The GlobalLink 520 bridges the gap between remote installations and reliable system insight. Equipped with an embedded 4G LTE-M modem and internal antenna, the unit delivers consistent global connectivity with no need for a SIM card or separate data plan—five years of data are included with purchase. LTE-M is optimised for IoT devices, supporting roaming and low-energy data transmission, making it ideal for mobile and remote applications.
• Seamless system integration: The unit features two VE.Direct ports, allowing direct connection to devices such as BMV Battery Monitors or MPPT Solar Charge Controllers. These connections feed live data into the VRM portal, enabling detailed system diagnostics, performance analysis, and configuration tools without the need for complex setup.
• Expanded control and input options: Equipped with two digital inputs (which can also act as pulse counters) and a remotely controllable relay, the GlobalLink 520 allows for versatile monitoring and automation. From reading sensor states to triggering external systems, this device puts operational control at your fingertips.
• Bluetooth connectivity for Smart products: Victron Smart devices with Bluetooth capability can be paired via VictronConnect, enabling wireless configuration and expanded monitoring capabilities, even without a wired VE.Direct connection.
• Built-in and external antenna support: The integrated internal antenna provides excellent coverage for most installations. However, for challenging environments or mobile installations like utility vans or boats, the unit supports connection to an external antenna to ensure optimal signal reception.
• RuuviTag sensor integration: The GlobalLink 520 now supports BLE-based RuuviTag environmental sensors, which measure temperature, humidity, and air pressure. This makes it a perfect all-in-one environmental and energy monitoring solution for off-grid, industrial, or mobile applications.
• Victron Remote Management (VRM): Access your system status and historical performance data in real-time through the VRM portal. Configure custom alarms, receive notifications, and generate detailed reports—all accessible from anywhere, at any time. Whether you’re monitoring one device or a full system, VRM offers comprehensive insight and control.

The GlobalLink 520 is supplied ready to install with built-in connectivity, making it the perfect entry-level remote monitoring tool for Victron installations. Reliable, efficient, and maintenance-free—it brings your energy system online, simply and securely.
