- Product Dimensions: 5 x 10 x 20.5 inches (approx. 127 x 254 x 521 mm)
- Item Weight: 33.1 pounds (approx. 15 kg)
4. Setup and Installation
Installation should be performed by a qualified professional. Ensure all local and national electrical codes are followed.
4.1 Mounting
- Mount the unit in a dry, well-ventilated area, protected from direct sunlight and extreme temperatures.
- Ensure sufficient clearance around the unit for proper airflow and cooling.
- Securely fasten the unit to a sturdy surface using appropriate mounting hardware.
4.2 Electrical Connections
Connect the MultiPlus Compact to your battery bank, AC input (shore power or generator), and AC output (loads) according to the wiring diagrams provided in the full product manual. Pay close attention to polarity and proper grounding.

5. Operating Instructions
5.1 Basic Operation
Once installed and configured, the MultiPlus Compact operates largely automatically. It will convert DC battery power to AC power when no external AC source is available and charge batteries when an AC source is connected.
5.2 PowerAssist Function
The PowerAssist feature prevents overloading of a limited AC source, such as a generator or shore power connection. If the AC load exceeds the capacity of the external source, the MultiPlus will automatically draw additional power from the battery to supplement the supply. When the load decreases, excess power from the AC source will be used to recharge the battery.
Figure 5: Illustration of the PowerAssist feature, showing how the MultiPlus supplements a limited AC source with battery power.
5.3 Uninterrupted AC Power (UPS Function)
In the event of a grid failure or disconnection of shore/generator power, the inverter within the MultiPlus automatically activates within 20 milliseconds. This rapid transfer ensures that connected loads, including sensitive electronic equipment, continue to operate without interruption.

5.4 Adaptive Charging
The MultiPlus Compact features a four-stage adaptive charging process (Bulk, Absorption, Float, Storage) to ensure optimal battery health and longevity. The BatterySafe Mode is integrated into the absorption time calculation, preventing excessive gassing by limiting the rate of voltage increase once the gassing voltage is reached.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your MultiPlus Compact.
- Cleaning: Keep the unit clean and free from dust and debris. Use a dry cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure ventilation openings are not obstructed. Periodically check for dust buildup in cooling fins.
- Connections: Periodically inspect all electrical connections for tightness and signs of corrosion. Tighten any loose connections.
- Battery Health: Monitor battery voltage and temperature, especially during charging, to ensure proper operation.
7. Troubleshooting
This section addresses common issues. For more complex problems, consult the full product manual or contact Victron Energy support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No AC output from inverter | Low battery voltage, overload, or thermal shutdown. | Check battery voltage and charge if low. Reduce AC load. Allow unit to cool down if overheated. |
| Batteries not charging | No AC input, AC input breaker tripped, or charger settings incorrect. | Verify AC input connection and power. Check AC input breaker. Review charger settings via VictronConnect. |
| Unit making loud humming noise | Normal operation under heavy load or during charging, or loose mounting. | Ensure unit is securely mounted. Some noise is normal, especially during high current operation. If excessive, consult support. |
| Overload alarm | Connected AC loads exceed the unit's capacity. | Reduce the total AC load connected to the inverter. |
