Victron energy ASS030543020 GlobalLink 520 User Manual

1. Introduction

Thank you for purchasing a GlobalLink 520. It allows you to connect other Victron equipment (VE. Direct), such as your Battery Monitor (BMV); Smart Shunt; Solar Charger; IP43 Charger; or Phoenix Inverter, to the Victron Remote Management (VRM) portal. The portal is available to use free of charge, and from it you can view the status of your installation from anywhere in the world using your desktop device or mobile phone. Here are some examples of the kind of information you will be able to view:

• Inverter demo
• MPPT Solar Charger demo

The first five years of cellular connectivity is included in the purchase price. The unit will come pre-configured and ready for use out of the box. No need to change any settings.
Make sure you have LTE-M coverage in your country before purchasing this device: https://1nce.com/en/coverage/

2.2. Assembly instructions

1. Make note of the VRM Portal ID denoted on the sticker on the GlobalLink 520.
2. Mount the GlobalLink 520 close to the device you wish to monitor.
3. Connect VE.Direct cables between your devices and the GlobalLink 520.
4. Connect the DC Power (8V – 70V).
5. The LED will start blinking blue while it is trying to connect to the network (this could take up to 5 minutes).
6. The LED will blink green and yellow when one VE.Direct device is connected, or only green when two VE.Direct devices are connected.
7. Visit to the VRM portal to ‘add’ your installation to your account using the Portal ID you wrote down in step 1. You can only add your device to VRM once it has connected to the network (blinking yellow and/or green).

4. Cellular connectivity

The GlobalLink 520 is a cellular device which connects to LTE-M compatible 4G networks. The cellular provider of the included SIM card is ‘1nce’. Their global network of operators is constantly expanding and you can check LTE-M coverage in your area here: https://1nce.com/en/coverage/.

4.1. 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 (with an external antenna).

4.2. Antenna

The GlobalLink 520 has an internal antenna and an SMA connector for an optional external antenna. A switch on the top of the device determines which antenna is used. If the switch is set away from the SMA connector the internal antenna is used, when set towards the connector the external antenna is used.

Do not set the switch to “external” if there is no external antenna connected, as this can permanently damage your device.

The GlobalLink 520 is not rated for outdoor use. You can however connect your own outdoor antenna to the device to improve your signal strength if the internal antenna does not have good enough reception (note: you can find the signal strength in VRM). LTE-M uses the following frequencies: 703-803 and 2520-2620 MHz.

4.3. Internal SIM card

Inside the device is a Nano SIM card which is used for connectivity. This SIM is locked and can only be used in combination with this specific GlobalLink device. It has a limited data bundle for the device to operate and receive updates over the air.

5. Product compatibility

This device has two VE.Direct ports and is compatible with:

• All MPPT Solar Charge Controllers which have a VE.Direct Port
• BMV Battery Monitor 700 series
• BMV Battery Monitor 710 Smart series
• Phoenix Inverter VE.Direct models
• Smart Shunt
• IP43 Chargers

The device is not compatible with our Peak Power Packs. More information is also available on our website: https://www.victronenergy.com/panel-systems- remotemonitoring/globallink520

6. Power

The GlobalLink 520 can be powered directly from your battery bank and operates between 8V and 70V.

7. Data transmission to VRM

After power-up, the GlobalLink 520 will connect to the LTE-M network. Once connected, it will gather information from the connected VE.Direct device(s), and transmit it to the VRM portal.
Every 24 hours, all available data is transmitted. In between, it will transmit the most important data every 15 minutes:

• Inverter state (Off, Bulk, Absorption, Equalize, Float)
• Mode (On/Off/Eco)

8. Digital inputs

The GlobalLink 520 comes with two digital inputs which also act as pulse counters; you can view their current state the number of detected pulses (rising edge, 1000Hz max) in VRM.

9. Relay switch

The GlobalLink 520 comes with one relay which can be operated from VRM from the device list page.

You can queue changes to the relay state in VRM. Changes will be propagated the next time the device connects and transmits its data, and can thus take up to 15 minutes to take effect (or longer if the device has no connection).

10. Input Voltage Measurement

The GlobalLink measures the voltage on its own power connector. If none of the connected VE.Direct devices is able to measure voltage, this value is used instead in VRM.

Note that this measurement is not very accurate. At 14V it’s +/- 0.2V, at 24V it’s +/- 0.5V and at 48V it’s +/- 1V.

11. Firmware updates

The GlobalLink automatically checks and updates it’s firmware to the latest stable version. When the units starts updating the LED will blink purple. This can take up to 10 minutes. Do not power down the unit even if the LED stops blinking for a while.

All updates are currently rolled out automatically, it is not yet possible to manually update the device.

12. Troubleshooting

Step 1: Check the device has power. The LED on the device should be blinking in some color. If it is not blinking, check if the power cable is connected correctly and supplies sufficient power. If you’re using the included cable, be sure to also check its inline fuse which may be blown if the power pins were accidently reversed.
Step 2: Check for cellular (LTE-M) coverage. Verify that the LED is blinking either green or yellow. After powerup, the LED will first blink blue, indicating that it is establishing communication with the LTE-M network and VRM. Once connected, it will start blinking green (when there is a VE.Direct device) or yellow (when there is no VE.Direct device). In case it keeps blinking blue the unit will keep trying to establish a connection until there is a timeout (+/- 15 min) and then automatically reboot the device.

Check and make sure there is coverage in your country (https://1nce.com/en/coverage/). If there should be coverage but you have no signal you can consider purchasing an external antenna.
Step 3: Check the connected VE.Direct devices. Make sure the LED is blinking green or green & yellow which indicates that only one VE.Direct device is connected. In case its only blinking yellow, check the cable to the VE.Direct device, and power to the VE.Direct device.
Step 4: Find the device in the VRM portal Login to VRM, and add the module by going through the “Add installation” wizard. Only after the module has made an active connection to the cellular network it is available in VRM.
