Description
Victron MultiPlus 12/3000/120-50 230V VE.Bus
The Victron MultiPlus 12/3000/120-50 (230V Version) is a heavy-duty inverter/charger engineered specifically for the Australian market (230V/50Hz). This model is a staple in high-end 4WD setups, marine vessels, and off-grid cabins where reliable, high-current 12V-to-AC conversion is required.
The SKU for this specific Australian/International model is PMP123021010.

Advanced Technical Features
1. PowerAssist (Hybrid Logic)
In Australia, shore power or generator limits are often restricted (e.g., 10A or 15A outlets). PowerAssist allows the MultiPlus to supplement the AC source with battery power. If you try to run a 2400W air conditioner on a 10A (2300W) circuit, the MultiPlus will pull the remaining 100W+ from your 12V battery to prevent the source breaker from tripping.
2. Dual AC Outputs
-
AC-out-1: Protected by the UPS function. If the grid fails, this stays live.
-
AC-out-2: Only active when AC input (shore/generator) is present. Ideal for “dump loads” like water heaters or air conditioners that you don’t want accidentally draining your batteries when off-grid.
3. Sophisticated Networking (VE.Bus)
As a technically adept user, you can leverage the VE.Bus port to:
-
Parallel Units: Connect up to 6 units for a massive 18kVA output.
-
Three-Phase: Configure three units for a true 415V three-phase system.
-
ESS (Energy Storage System): Program the unit for self-consumption mode in grid-tied solar setups.
4. Adaptive 4-Stage Charging
The 120A charger is fully programmable via VEConfigure (requires MK3-USB) or VictronConnect. You can set custom charge curves for Lithium (LiFePO4), AGM, or Gel, ensuring the charge profile matches your specific battery chemistry’s internal resistance and thermal characteristics.
Installation Requirements & Recommendations
-
DC Fusing: A 400A Class-T or Mega fuse is recommended for the 12V side to handle the high surge currents.
-
Cabling: Due to the 120A charge current and 300W+ inverter draw, $2 \times 50mm^2$ (or $1 \times 95mm^2$) copper cabling is standard for runs under 5 meters to minimize voltage drop.
-
Monitoring: Pairing this with a Cerbo GX and Touch 50/70 provides the ultimate telemetry dashboard via the VRM portal.
