Victron Energy GlobalLink 520 & 530 - VRM Monitoring Gateway with 5-Year Prepaid SIM

The Victron GlobalLink 520 and 530 are the easiest, no-subscription way to keep an eye on a Victron system from anywhere. They link your gear to the free VRM (Victron Remote Management) portal over cellular — and ship with a pre-installed, pre-paid SIM that includes 5 years of connectivity. No SIM to buy, no data plan to manage, no monthly fees. Power it up, pair your devices, and watch your system online.

Which model?

• GlobalLink 520 — connects over LTE-M (CAT M1), the low-bandwidth IoT network, with 17 bands supported for near-worldwide coverage. The proven choice where LTE-M service is available.
• GlobalLink 530 — the newer model with a 4G LTE Cat 1 modem (up to 10 Mbps down / 5 Mbps up) and 2G GSM/GPRS/EDGE fallback, providing reliable coverage in many parts of the world — including areas where LTE-M is thin or absent.

Both models are otherwise identical: same ports, same VRM features, same 5-year prepaid SIM. Pick by the cellular coverage where your boat, rig, or cabin actually lives.

What it connects

• 2 VE.Direct ports (always isolated) — wire in two VE.Direct devices such as a SmartSolar MPPT, a SmartShunt, or a BMV battery monitor. (The Multi RS also uses this VE.Direct link for GlobalLink monitoring.)
• Up to 10 Bluetooth Smart products — the GlobalLink pulls data wirelessly (BLE) from nearby Victron Smart devices.
• RuuviTag sensors — add wireless temperature, humidity, and pressure sensors; their data shows up directly in VRM.
• 2 digital inputs and 1 relay (NO/NC; DC 2 A @ 30 VDC, AC 0.5 A @ 125 VAC) for basic alarm/switching.

On VRM you can watch battery state of charge, power consumption, PV harvest, generator and grid status, and temperatures, set up alerts, and review historical data and diagnostics — all from your phone or laptop.

Easy setup and flexible antennas

Configure it in minutes over Bluetooth with the VictronConnect app. Both models have an internal antenna plus an SMA connector for an optional external antenna — add the outdoor wall-mount or puck antenna (3 m lead) where signal is weak, such as inside a metal hull or enclosure. After the included 5 years, both units also support a custom SIM.
