About the Phoenix 12/3000 Pure Sine Wave 120V Inverter
The Phoenix 12/3000 takes in 12V DC and outputs 120V, 60Hz pure sine wave power. That is the entire job. There is no charger, no AC input, and no transfer switch, so shore or generator power cannot pass through the unit or be blended with battery power.
That makes it the right pick when charging is already handled by an MPPT controller, a DC-DC charger, or a standalone AC charger, and the only gap is clean AC output. It is also the right pick when AC loads need to stay permanently isolated from utility power.
Continuous Power Output and Temperature Derating
The 2,400W rating is measured at 77°F. Victron publishes the full curve: 2,200W at 104°F and 1,700W at 150°F. Cooling is fan-assisted and the unit runs from -40°F to 150°F, so it keeps working in a hot space, just at lower continuous output.
Size against the temperature the inverter will actually see. A ventilated equipment room supports the full 2,400W. A sealed RV bay, an engine room, or an uninsulated garage should be sized to 2,200W or below.
6,000W Surge Capacity for Motor Loads
Peak output is 6,000W, more than double the continuous rating. Victron credits its SinusMax topology, which pairs high-frequency conversion with line-frequency output handling. In practice this starts loads that stall lower-surge inverters: refrigeration and air conditioning compressors, well pumps, air compressors, table saws, and most single-phase induction motors.
The battery side has to keep up. A 6,000W surge at 12V nominal pulls over 500A for the duration of the start, and the bank, busbars, and cable all have to deliver it without terminal voltage sagging under the 9.5V cutoff. Undersized DC wiring is the most common reason a correctly sized inverter will not start a motor.
Parallel, Split-Phase, and Three-Phase Operation
Up to six identical units tie together over VE.Bus with standard RJ45 UTP cables, giving 18kVA and 14.4kW continuous in a six-unit stack. Two units configured for split phase produce 120/240V from a 12V bank, which covers North American 240V loads such as a well pump, a dryer, or a mini split. Three-phase wye is supported, but three-phase delta is not.
VE.Bus Configuration and GX Monitoring
Two RJ45 VE.Bus ports handle both inter-unit communication and system integration. Tied to a Cerbo GX or Ekrano GX, the inverter reports into the VRM Portal remotely, with alarms by email or push notification.
Deeper configuration runs through VEConfigure with an MK3-USB interface. Adjustable parameters include output voltage from 95-128V, frequency at 50Hz or 60Hz, over- and under-voltage thresholds, and relay behavior. A VE.Bus Smart Dongle adds Bluetooth access where there is no GX device. Onboard DIP switches cover the common settings without a computer: AES mode, 115V or 120V output, and 50Hz or 60Hz.

Frequently Asked Questions
No. It is an inverter only, with no AC input, no charger, and no transfer switch.
2,400W at 77°F, 2,200W at 104°F, and 1,700W at 150°F. Size your system appropriately against the temperature the inverter will actually see.
Usually. Peak output is 6,000W, which covers most single-phase motor starts in this class. The limit is normally the battery bank and DC cable, since a 6,000W surge at 12V draws over 500A.
Not from one unit. Two identical units configured for split phase over VE.Bus produce 120/240V. A single unit is 120V only.
Up to six, for 18kVA and 14.4kW. All units must be the same model, DC cables must match in length and cross section, and RJ45 cables must run directly between units without splitters.
Victron recommends between 400-1,200Ah of battery capacity with a 400A DC fuse on the positive cable. Under 16ft, use two 50 mm² conductors, roughly 1/0 AWG, on each of the positive and negative terminal pairs. Longer runs step up to 70 mm², or 2/0 AWG. Cables are not included.
No. Victron publishes EN 60335-1 and EN 55014 compliance plus a RETIE certificate for Colombia, but no UL 458 or UL 1741 certificate for this model. Where listed equipment is required, look at the UL certified MultiPlus-II 12/3000/120-50 120V.
No. The inverter runs stand-alone on factory settings of 120V and 60Hz. A GX device adds display, VRM monitoring, remote control, and alarms. An MK3-USB is needed for full configuration in VEConfigure.
