Victron Energy Quattro Inverter/Charger 230V (Euro 50Hz) - 3kVA to 15kVA

Note: This is a 230V / 50Hz (European standard) model with a single-phase output, most often used as a like-for-like replacement on a European-built boat. For US-standard 120/240V split phase you have three options: (1) configure the Quattro for 60Hz and pair it with a Victron Autotransformer also set to 60Hz, which splits the 230V/60Hz output into 120/240V; (2) use a Quattro-II 2x120V single-box split-phase unit; or (3) wire two Quattro 120V units in parallel (one per leg).

The Victron Quattro is a true marine- and off-grid-grade inverter/charger with two AC inputs. It combines a low-distortion pure sine wave inverter, a smart adaptive charger, and an integrated dual-AC-input transfer switch in one enclosure - so shore power, a generator (or two generators), your battery bank, and your loads all live behind one device.

This 230V / 50Hz listing spans 3 kVA to 15 kVA, at 12V, 24V, or 48V DC. Choose your model from the variant selector above.

Who the Quattro is built for

• European-built boats and yachts - a like-for-like 230V / 50Hz inverter/charger that auto-selects between shore power and a generator with a sub-20 ms changeover.
• Off-grid homes and larger installs - the 8 kVA, 10 kVA, and 15 kVA models handle whole-home off-grid loads from a 48V bank, with a generator input built in.
• Systems with shore power and a generator - the Quattro's two AC inputs and automatic source selection mean no external transfer switch.
• Installers and electricians - VE.Bus communication, VEConfigure, and parallel/three-phase scaling to very large systems.

Why this is the Quattro

Two AC inputs with an integrated transfer switch

Connect both shore power and a generator (or two generators) directly to the Quattro. It detects which source is live and switches automatically - no external transfer switch, no relays to size, no second enclosure on the wall.

No-break AC output and two AC outputs

The main output rides through any source loss in under 20 milliseconds, fast enough that computers and other electronics keep running. The second AC output is live only when an AC source is present - so non-critical loads like a water heater can't drain the battery overnight.

PowerControl and PowerAssist

Set a current limit on each AC input and the Quattro uses only the leftover capacity for charging, so the inlet breaker never trips (PowerControl). When a peak load exceeds the inlet rating, it supplements from the battery and recharges once the peak passes (PowerAssist). You can run loads larger than your inlet rating.

Adaptive multi-stage charging - lithium and lead-acid friendly

A four-stage charge profile (bulk, absorption, float, storage) with adaptive-charge software and an included battery temperature sensor, fully programmable for lithium, AGM, gel, and flooded banks. Maximum charge current ranges from 70 A (24/3000) up to 220 A (12/5000), by model. The 12V and 24V models also include a 4 A starter-battery trickle output.

Scales with your system: parallel and three phase

Three units configure for three phase, and up to four sets of three 15 kVA units can be paralleled for a 144 kW / 180 kVA system with 2,400 A of charging capacity. Configure with VE.Bus Quick Configure and VE.Bus System Configurator.

Monitor and control from anywhere

Add a Cerbo GX or Ekrano GX and your system is visible in the free VRM Portal from your phone, tablet, or laptop. Configure on-site with VEConfigure (via the MK3-USB interface) or the VictronConnect app over Bluetooth (via the VE.Bus Smart dongle).

Installation and sizing help

Wiring a Quattro isn't plug-and-play. Battery cable sizing, fusing, both AC inlet ratings, and bonding all need to match the variant you choose. Two free resources to start with:

• Victron Wiring Unlimited - the canonical reference for sizing the DC and AC sides of a Victron system.
• Our AWG to Metric Conversion chart.

Frequently asked questions

What's the difference between the Quattro and the MultiPlus-II?

The MultiPlus-II has one AC input. The Quattro has two AC inputs with a built-in transfer switch. If you have both shore power and a generator (or two generators) and want automatic source selection, the Quattro saves you an external transfer switch.

Can I use this 230V unit on US 120/240V power?

Not directly - its output is 230V / 50Hz (European standard). To run on US power, configure the Quattro for 60Hz and pair it with a Victron Autotransformer also configured for 60Hz, which converts the 230V/60Hz output into US-standard 120/240V split phase. Alternatively, the Quattro-II 2x120V or two Quattro 120V units in parallel give US split phase directly.

Is it lithium battery compatible?

Yes. The charger supports custom voltage and current profiles for LiFePO4 and other lithium chemistries, and it communicates with Victron's VE.Bus BMS over the communication port.

What warranty does it come with?

A 5-year limited warranty from Victron Energy, upgradable to 10 years for an additional 10% of the purchase price. Blue Marine handles the warranty claim process for you. Email support@bluemarine.com.
