This Victron Phoenix Inverter Smart review looks at Victron’s larger standalone inverters with built-in Bluetooth, from 1600VA to 5000VA. They add app monitoring and an ECO mode to Victron’s proven inverter design. One big caveat before anything else: the Inverter Smart range in Victron’s datasheet has a 230VAC output, so it’s built for markets outside North America, not standard US 120V wiring.

Source: Victron Inverter Smart 1600VA–5000VA datasheet. Output 230VAC ±2%, 50Hz or 60Hz; adjustable 210–245V. IP21, -40 to +65°C.
Features
- Built-in Bluetooth for monitoring and settings in VictronConnect.
- ECO mode: the inverter goes to standby under a set load and checks every 2.5 seconds (adjustable) whether to switch back on.
- High surge: peak power is 2–2.5× the continuous rating in this range.
Pros
- Strong peak ratings for motor starts.
- Low idle draw for its size, with ECO mode lower still.
- App monitoring without extra dongles.
Good to Know Before You Buy
- 230V output: not a fit for standard US 120V appliances and panels.
- No charger or transfer switch (Victron suggests its Filax transfer switch for low-power inverters).
Who It’s For and US Alternatives
It suits 230V markets and specialty builds. For US 120V systems, look at the Phoenix VE.Direct 120V models (up to 1,500W) or the Phoenix 3000VA 120V, or step up to a MultiPlus-II if you want charging.
Settings You Can Change in VictronConnect
Victron’s datasheet lists these as configurable over Bluetooth:
- Low battery voltage alarm, plus cut-off and restart levels
- Dynamic cut-off, a load-dependent low-voltage shutdown
- Output voltage (210–245V) and frequency (50 or 60Hz)
- ECO mode on/off and its sense level
- The alarm relay, which can be set for a general alarm, DC under-voltage or generator start/stop (rated 4A at 35VDC, 1A at 60VDC)
The VE.Direct port also allows setup from a computer with a VE.Direct to USB cable.
Setup and Troubleshooting Tips
- “It’s not 120V.” The datasheet lists 230V output, adjustable 210–245V. It isn’t a North American 120V inverter. US buyers should look at the Phoenix 3000VA 120V or a MultiPlus-II 120V.
- Can’t parallel two units. The datasheet states that parallel and 3-phase operation aren’t supported. For more power, choose a bigger model or a VE.Bus Phoenix.
- ECO mode keeps cycling. In ECO mode the inverter checks for load every 2.5 seconds by default. If a small load doesn’t keep it on, adjust the sense level, or turn ECO off for that load.
- Shutting down on a heavy load. Check the dynamic cut-off settings and battery cable size, since voltage sag under load can trip low-voltage protection.
- Fault indications. Victron lists seven protections: output short circuit, overload, battery voltage too high, battery voltage too low, temperature too high, 230VAC on the inverter output, and input voltage ripple too high. The last often points to undersized cables or a weak battery.
Who It Suits
230V markets, plus specialty builds needing 230V, that want app control without a GX device.
VA vs Watts
The model names are in VA, but the spec table gives continuous watts. Plan around the watts: the 3000VA unit delivers 2,400W continuously at 25°C, and less when hot. At 65°C ambient the same unit is rated 1,700W.
Battery Current Worked Examples
Assuming about 92% efficiency at full load:
| Model and battery | Continuous load | Approx. battery current |
|---|---|---|
| 1600VA at 12V | 1,300W | about 118A |
| 3000VA at 24V | 2,400W | about 109A |
| 3000VA at 48V | 2,400W | about 54A |
| 5000VA at 48V | 4,000W | about 91A |
These figures drive cable and fuse choices; follow the manual’s cable tables for your model and cable length.
Standby Energy
Zero-load power applies whenever the inverter is on with nothing running. The 3000VA model at 12V draws 12W, about 290Wh a day, which is a meaningful share of a small solar budget. ECO mode, covered in the FAQ, reduces this when loads are off.
Worked examples are arithmetic estimates from the published ratings above, not test results. Real numbers depend on temperature, cable runs, battery state and load.

FAQ
Is there a 120V Phoenix Inverter Smart?
Victron’s Inverter Smart 1600VA–5000VA datasheet lists 230VAC output only. Check Victron’s site for regional models.
What is ECO mode?
A standby mode that cuts idle consumption when there’s no load, switching back on when a load appears.
Phoenix Smart or MultiPlus?
MultiPlus if you need shore or generator charging; Phoenix Smart for inverter-only setups in 230V markets.
Does it have a transfer switch?
No. Victron suggests its Filax transfer switch, or a MultiPlus instead.
Can it connect to a Cerbo GX?
Yes, through the VE.Direct port.
Remote switch?
Yes. A two-pole connector accepts a remote on/off switch.
How much does heat reduce output?
The 3000VA model is rated 2,400W at 25°C, 2,200W at 40°C and 1,700W at 65°C. Good ventilation keeps it closer to the higher figures.
Does it have Bluetooth?
Yes. The Smart models have Bluetooth built in for setup and monitoring in VictronConnect.
