Victron Inverter 12/2k5 230V Smart

The Victron Inverter 12/2k5 230V Smart is a pure sine wave inverter for high-performance 12-V battery systems. It provides a stable 230-V AC voltage, powering suitable household appliances, electronics, and tools far from the power grid. Its toroidal transformer topology combines a clean output voltage with high short-term power for loads with high inrush current.

With 2,400 W continuous power at 25 °C, With 3,200 W for up to 15 minutes during a cold start and a peak output of 4,000 W for 5 seconds, this model handles many demanding applications. Bluetooth and the VictronConnect app allow for configuration and local monitoring without the need for additional Bluetooth accessories.

The Main Benefits

• Stable 230-V sine wave voltage: Suitable for many electronic devices and loads, provided their power and inrush current requirements fall within the device's limits.
• High starting power: Up to 4,000 W for 5 seconds helps start loads such as power tools or certain motor-driven devices.
• Built-in Bluetooth: Settings and current operating values can be accessed via VictronConnect on a smartphone, tablet, or computer.
• ECO Mode: When the load is low, the inverter switches to standby mode and reduces the no-load power consumption of the 12-V model to 1.3 W.
• System Integration: VE.Direct, a remote on/off connection, and a programmable relay provide flexible options for monitoring and control.
• Protective features: including protection against short circuits, overloads, excessive temperatures, and battery voltages that are too low or too high.

Suitable Applications

The inverter is designed for self-contained 12-V systems that require a reliable 230-V power supply. Typical applications include:

• RV, Expedition, and Adventure Vehicles
• Boats and Yachts with a 12-V Electrical System
• Mobile workshops and service vehicles
• Allotment gardens, hunting cabins, and other stationary off-grid systems

It is not just the rated power of the load that matters. For refrigerators, pumps, compressors, and power tools, the inrush current must also be taken into account. Actual operation also depends on battery capacity, battery type, BMS approvals, DC wiring, and fuses.

Configuration and Monitoring with VictronConnect

The Victron Inverter 12/2k5 Smart can be connected locally to the VictronConnect app via its built-in Bluetooth interface. Configurable settings include output voltage, 50- or 60-Hz frequency, shutdown and restart thresholds for low battery voltage, dynamic shutdown, ECO mode, and the programmable relay.

VictronConnect displays battery voltage, AC output voltage, load, operating status, relay status, as well as warnings and alarms. For integration into a Victron system, it also offers VE.Direct is available. A Cerbo GX, Ekrano GX, or GlobalLink 520 requires a separately purchased compatible VE.Direct-Kabel. With an internet-enabled GX device, remote monitoring is possible via the VRM Portal.

ECO Mode for Lower Power Consumption

During normal operation, the no-load power of the 12-V model is 10 W. In ECO mode, the inverter enters standby mode when the load falls below a configurable threshold and checks at regular intervals to see if a load is present again. As a result, the no-load power drops to 1.3 W. For loads with very low or irregular power consumption, the detection threshold must be adjusted accordingly, or normal operation must be selected.

Connections and System Boundaries

The battery is connected via M8 bolts, and the 230-V output via screw terminals. A remote on/off connection can be used with an external switch, a relay contact, or a suitable BMS control signal. The programmable relay can be configured, for example, for alarm messages or external control tasks.

Technical Specifications

Installation Instructions

The inverter must be installed in a dry, well-ventilated location as close to the battery as possible. Allow approximately 10 cm of clearance around the unit to ensure proper air circulation. Due to the high currents on the 12-V side, the battery, BMS, DC cable, fuse, disconnect device, grounding, and AC protective devices must be sized appropriately for the system.

Conclusion

The Victron Inverter 12/2k5 230V Smart is a suitable choice when a high-performance pure sine wave inverter is needed for a 12-V off-grid system. Its combination of stable sine-wave output, high short-term power, configurable ECO mode, and Victron interfaces makes it easy to use in both mobile and stationary off-grid systems. To ensure a reliable overall solution, the battery and installation must be designed to handle the high DC power consumption.

Frequently Asked Questions About the Victron 12/2k5 Smart Inverter

• What are the continuous and peak power ratings of the 12/2k5 inverter?

  
  

  The 12-V model delivers 2,400 W continuous at 25 °C. During a cold start, 3,200 W is available for 15 minutes; the peak power is 4,000 W for 5 seconds. As the ambient temperature rises, the available continuous power decreases.

• Is there a charger or transfer switch installed?

  
  

  No. The device converts 12-V DC to 230-V AC, but it does not charge the battery and does not have a built-in transfer switch. For these functions, you should consider a properly designed inverter-charger solution.

• Can the inverter be operated in parallel or in three-phase mode?

  
  

  No. The manufacturer does not allow either parallel operation or three-phase operation for this model.

• What settings can be configured via Bluetooth and VictronConnect?

  
  

  Configurable parameters include output voltage, frequency, ECO mode, alarm relays, and shutdown and restart thresholds for low battery voltage. In addition, load, battery voltage, output voltage, operating status, and alarms can be monitored locally.

• Is the inverter suitable for any 12-volt battery system?

  
  

  The system voltage is correct if the battery operates within the DC input range of 9.3 to 17 V. In addition, the battery, BMS, cables, and fuses must be capable of handling the high power consumption and transmitting it safely. The system must be designed in accordance with the manufacturer’s manual.
