4. Setup

The MultiPlus is designed for easy installation. A wall mount plate is included for secure mounting. Ensure all connections are made correctly and securely.

1. Wall Mounting: Secure the included wall mount plate to a sturdy surface. The MultiPlus unit has a hook at the back that fits into this plate.
2. Battery Connections: Connect the battery cables to the designated terminals. Use a torque wrench with an insulated box spanner to tighten connections to a maximum of 7 Newton-meters to prevent shorting.
3. AC Mains and Load Connections: Connect the AC mains input and AC load output cables to the appropriate terminals.
4. Accessory Connections: Connect any desired accessories, such as a Venus GX, Color Control GX, or current transformer, to the unit's ports.
5. Power On: Locate the switch at the bottom of the unit. Position '1' means on, '0' means off, and '2' means charger only.

5. Operating

The MultiPlus offers flexible operating modes and monitoring capabilities.

• Operating Modes: Select between 'On' (inverter and charger active), 'Off', or 'Charger Only' using the physical switch on the unit.
• PowerAssist: This feature automatically reduces battery charging when an overload is detected on the AC input, and can boost the AC output by drawing power from the battery when needed.
• VictronConnect App: Use the free VictronConnect app on your Android or iOS device to monitor, operate, and configure your MultiPlus. Connect via Bluetooth, USB, or WiFi/LAN/Internet (with a GX device).
• VRM Portal: For remote monitoring and management, connect your MultiPlus to the Victron Remote Management (VRM) portal via a GX device. This allows you to view system performance data and configure settings from anywhere with internet access.
