At lunchtime, you charge your camera batteries and work intently on your laptop, while in the evening you prepare a delicious meal on the induction hob. It is the seamless availability of energy that transforms a remote location into a real home.
The foundation of your energy supply: performance, efficiency, and technical data
This powerhouse focuses on one core task and masters it with flying colors: providing clean and stable 230V AC power. Its design as a pure inverter aims to deliver maximum performance and reliability in systems where charging functions are handled by dedicated components such as solar charge controllers or mains chargers.
-
Function: As a pure inverter, it converts 24V direct current (DC) from your battery into stable 230V alternating current (AC) with a flawless sine wave. This ensures the safe and trouble-free operation of even the most sensitive electronics.
-
Continuous power: An impressive 4000 W at 25 °C. Enough energy to power several energy-intensive household appliances in parallel.
-
Peak power: A massive 10,000 W thanks to SinusMax technology. This means that even demanding consumers such as air conditioners, water pumps, or large power tools can be started effortlessly.
-
Maximum efficiency: Efficient 95%, getting the most out of your valuable battery reserve.
-
Protection class: IP21 (Ingress Protection 21) offers protection against solid foreign bodies and dripping water, provided the device is mounted with the connections facing downwards.
On a hot summer day, the air conditioning in your motorhome is running at full speed, while the hair dryer is being used in the bathroom and the refrigerator compressor is starting up at the same time. The Phoenix Smart handles this combined load with ease and without any drop in performance – that's the tangible security that a real power reserve offers in everyday life.
More than just power: smart control, protective functions, and efficiency
The Phoenix Inverter Smart is much more than just a powerful power generator. It is packed with intelligent features that give you full control and take the efficiency of your entire system to a new level.

Areas of application: From self-sufficient motorhomes to off-grid solar systems
Its enormous performance and robust design make this inverter ideal for a wide range of demanding applications where a reliable power supply far away from the grid is crucial.
-
Marine applications ⛵: On yachts and boats, which often already have separate chargers, the Phoenix Smart confidently supplies power for kitchen appliances, air conditioning systems, or water treatment systems and reliably starts critical pumps and motors.
-
Large recreational vehicles 🚐: In converted buses or luxury motorhomes, it provides living comfort almost like at home. ECE R10-5 certification ensures trouble-free and reliable operation in the vehicle.
-
Stationary off-grid systems 🏡: For tiny houses, vacation cabins, or self-sufficient workshops, it forms the ideal centerpiece of a modular system. Especially when power is generated by a dedicated PV (photovoltaic) system, it offers a straightforward and extremely powerful inverter solution.
The converted van serves not only as a home on four wheels, but also as a mobile office. Thanks to the powerful power supply, computers, monitors, and even the portafilter espresso machine can run simultaneously—the basis for productive work in the most beautiful locations. It is the freedom to design your own working and living space without any electrical compromises.
System optimization: Recommended accessories and important additions
-
DC fuse (400 A) & disconnect switch: These two components are absolutely essential for the safety of your system. The fuse protects against catastrophic short circuits and is installed as close to the battery as possible. The disconnect switch allows you to completely and safely disconnect the inverter from the power source for maintenance work.
-
Victron Cerbo GX: This is the communication hub for your energy system. By connecting via the VE.Direct port, the Phoenix Smart's data is integrated into the overall system. This enables detailed local monitoring as well as worldwide remote monitoring and analysis via the free Victron VRM portal.
-
Battery monitor (e.g., Victron SmartShunt): Think of it as the precise "fuel gauge" for your battery bank. It accurately measures the state of charge (SoC), energy consumption, and remaining autonomy. This data is crucial for efficient energy management and maximizing battery life.
-
Victron Filax Automatic Transfer Switch: If an uninterruptible power supply (UPS) is required, the Filax is the perfect addition. Since the Phoenix Smart is a pure inverter, the Filax takes over the task of switching to inverter mode instantly and without interruption in the event of a failure of the external AC source (e.g., shore power).

Decision aid: Which 5000 VA device is right for me?
-
For pure inverter applications: If you already have separate chargers (solar/mains) and only need an extremely powerful and reliable 230V source, the Phoenix Inverter Smart is the ideal, uncomplicated choice.
-
For an all-in-one solution: If you are looking for a single component that integrates inverter, shore power/generator charging, and UPS functionality, the MultiPlus-II is the superior choice as it reduces space and complexity.
-
For grid-interactive solar systems (ESS): If you want to store solar power, use it at night, and interact intelligently with the grid, the MultiPlus-II is a must, as it is specifically designed for these demanding tasks.
-
For future power upgrades: If you need 4000 W today but want to keep the option open to upgrade later (e.g., to 8000 W or a three-phase system), you must choose the MultiPlus-II. Its VE.Bus architecture enables this scalability, which the Phoenix Smart lacks.
Installation guide: How to ensure safety and maximum performance
Proper installation is the key to safety and optimal performance. Installation should always be carried out in accordance with the manual and by qualified personnel.
-
Location selection: Install the device in a dry, well-ventilated location with at least 10 cm of free space on all sides. Avoid mounting directly above lead-acid batteries.
-
DC cabling: The most critical point. The official manual recommends a total cross-section of 150 mm² ( e.g., 2x 70 mm² per pole) for lengths up to 5 meters. Undersized cabling is the most common source of errors.
-
Fuse protection: An external 400 A fuse in the positive battery line, installed as close to the battery as possible, is mandatory.
-
Grounding: The housing must be properly connected to the system ground (vehicle frame, boat hull) to ensure electrical safety (protection class I).
Important questions answered: Your FAQs on operation, selection, and system planning
-
Why does my inverter switch off under load even though the battery is full?
The cause is usually insufficient DC cabling. Cables that are too thin or too long lead to high voltage drops. Check that the cable cross-section complies with the official recommendation of 150 mm² ( up to 5 m) and that all connections are secure. The "High DC ripple" alarm in the app is a clear indicator.
-
When should I choose this inverter instead of a MultiPlus-II?
Choose the Phoenix Smart if you are planning a pure off-grid system with separate chargers. It is ideal if you are looking for maximum inverter performance and easy configuration and can do without integrated charging, UPS, or grid interaction functions.
-
Can I increase the power later by adding a second device?
No, this is a fundamental feature of the device. The Phoenix Inverter Smart uses a VE.Direct interface and is not designed for parallel or three-phase operation. For future scalability, VE.Bus devices such as the MultiPlus-II are the right choice.
-
What does the flashing green "Inverter" LED mean when the device is idle?
The device is in "search mode" of the activated ECO mode and is checking for load. Connect a load that exceeds the set threshold or adjust the ECO parameters in the VictronConnect app to start normal operation.
