Description
The Victron Phoenix 12V 3000W is a high-power pure sine wave inverter that converts your 12V battery bank into a full 120V AC power source. 3000VA continuous output with ~6000W peak handles everything from power tools to air conditioners. VE.Bus communication enables up to 6 units in parallel (18kVA) or three-phase configuration for large installations.
Key Features
- ✓ 3000VA / 2500W continuous — powers large appliances: microwave, AC, power tools, hair dryer, coffee maker simultaneously.
- ✓ Pure sine wave output — safe for sensitive electronics, medical equipment, and variable-speed motors.
- ✓ VE.Bus communication — parallel up to 6 units (18kVA) or configure three-phase for commercial installs.
- ✓ ~6000W peak power — handles motor startup surges from compressors, pumps, and large tools.
- ✓ 93-95% efficiency — minimal energy loss from battery to appliance.
- ✓ 5-year Victron warranty — global service network, proven marine and off-grid reliability.
Important: Inverter Only
This is a pure inverter — it does NOT include a built-in battery charger or transfer switch. If you need inverter + charger + transfer switch in one unit, look at the Victron MultiPlus 12/2000 or MultiPlus-II 12/3000 instead. The Phoenix is for systems where charging is handled separately (solar, DC-DC, dedicated charger).

Applications
- Large off-grid systems — cabin, home backup, remote power where high AC loads are required
- Marine liveaboard — run full galley appliances, AC, and entertainment from battery bank
- RV with heavy AC loads — air conditioner, microwave, induction cooktop from lithium bank
- Mobile workshop — power tools, compressors, welders from vehicle battery system
- Commercial/industrial — parallel multiple units for 6-18kVA systems
Compatible Batteries
- Dakota Lithium DL+ 12V 320Ah — recommended minimum for sustained 2500W loads
- Dakota Lithium 12V 100Ah (×2-4) — parallel bank for extended runtime
- Dakota Lithium DL+ 12V 135Ah — good match for moderate loads
At 2500W from 12V, this inverter draws ~220A. A large battery bank (200Ah+) is essential for meaningful runtime.
FAQ
Why choose this over the MultiPlus?
The Phoenix is a dedicated inverter with no charger overhead — higher efficiency for pure inverter duty, lower cost, and parallel to 6 units vs 4 for MultiPlus. Choose the Phoenix when your charging is handled by separate equipment (solar controller, DC-DC charger, dedicated AC charger). Choose the MultiPlus when you want everything in one box.
What size battery bank do I need?
At full 2500W load from 12V: 100Ah lasts ~30 minutes, 200Ah ~1 hour, 320Ah ~1.5 hours. For typical mixed loads (500-1000W average), double those estimates. A 200Ah+ bank is the practical minimum for this inverter.
Can I parallel this with a MultiPlus?
No. VE.Bus parallel only works between identical units. You can parallel multiple Phoenix 12/3000s together, but not mix Phoenix with MultiPlus. They can coexist in a system via a GX device but won’t share load.
