• A GX device
• The VRM Portal (GX device or
• The SmartSolar Control display
• The MPPT Control - an external display that connects to the VE.Direct port (the VE.Direct cable is not included with the MPPT
Control)

3.7. VE.Direct port

The VE.Direct port is used to communicate with the solar charger. It can be used for several purposes:
• To connect to a monitoring device, such as a GX device or the GlobalLink.
• To connect with the VictronConnect App.
• For external control.
Special cables or interfaces are needed to connect to this port:
• VE.Direct cable - used to connect to a GX device or the GlobalLink.
• VE.Direct to USB interface - used to connect via USB to the VictronConnect App.
• VE.Direct Bluetooth Smart dongle
• VE.Direct TX digital output cable
• VE.Direct non inverting remote on/off cable

3.8. VE.Can ports

The VE.Can ports are used to communicate with the solar charger. It can be used to connect to a monitoring device, such as a
GX device.
It is possible to connect several "daisy chained" VE.Can solar chargers (or other VE.Can devices) to a single GX monitoring
device. All interconnected solar chargers will synchronise their charge algorithms.
When connecting to this port, a
VE.Can RJ45 terminator installed (2 pieces are included). A connection example is shown in below figure.

3.9. Battery charging

3.9.1. Adaptive 3-stage battery charging

The solar charger is a 3-stage charger. The charge stages are: Bulk – Absorption – Float.
Bulk
During the bulk stage the solar charger delivers the maximum charge current, to rapidly charge the batteries. During this stage
the battery voltage will slowly increase. Once the battery voltage has reached the set absorption voltage, the bulk stage stops and
the absorption stage will commence.

- an external display that plugs into the front of the solar charger
- used to connect via Bluetooth to the VictronConnect App.
- used for streetlight control or to create a virtual load output.
- used to remotely switch the solar charger on or off.
RJ45 UTP Cable is used (not included). The first and last device in the chain needs to have a
