Why Choose the Victron Quattro for Marine Applications

The Quattro 48/5000/70 is specifically designed for vessels requiring uncompromising power reliability. Its dual AC input capability eliminates the need for separate transfer switches, while the advanced PowerAssist feature maximizes the utility of limited generator or shore power capacity. The unit's UL listing ensures compliance with North American electrical codes, making it ideal for both recreational and commercial marine installations.

Victron Energy's renowned build quality and comprehensive support network provide the confidence needed for offshore cruising and professional marine applications. The Quattro's field-proven reliability and advanced features make it the preferred choice for serious mariners worldwide.

Frequently Asked Questions

Can the Quattro operate as a standalone inverter without AC input?

Yes, the Quattro can operate in inverter-only mode, converting 48V DC battery power to 120V AC power when no shore power or generator source is available. It seamlessly transitions between all operating modes automatically.

What size generator is recommended for this unit?

A minimum 8kW generator is recommended to fully utilize the 70A charging capability while supplying house loads. The PowerAssist feature allows smaller generators to be supplemented with battery power during high-demand periods.

Is professional installation required?

Due to the high-power DC and AC connections involved, professional installation by a certified marine electrician is strongly recommended. Proper installation ensures optimal performance and compliance with marine electrical codes.

Can multiple Quattro units be connected together?

Yes, up to six Quattro units can be connected in parallel for increased power output, or configured for three-phase operation. This requires VE.Bus communication cables and proper system configuration.

What monitoring options are available?

The Quattro integrates with Victron's Color Control GX, Cerbo GX, and other VE.Bus compatible monitors for local and remote system monitoring via the VRM portal and mobile apps.

Multifunctional

Similar to the MultiPlus, the Quattro is also a combined inverter and charger. Additionally, it can accept two AC inputs and automatically connect to the active source. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology plus multiple system integration features such as three or split-phase operation and parallel operation.

Two AC Inputs & Two AC Outputs

The Quattro can be connected to two independent AC sources, for example, shore-side power and a generator, or two generators. The Quattro will automatically connect to the active source. The main output has no-break functionality. In the event of a grid failure, or shore or generator power being disconnected, the Quattro takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. The second output is live only when AC is available on one of the inputs of the Quattro. Loads that should not discharge the battery, such as air-conditioning or a water heater can be connected to this output.

Unique PowerAssist Feature

The Quattro will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.

Virutually Unlimited Power Thanks to Parallel Operation

Up to 6 Quattros can operate in parallel to achieve higher power output. Three phase or split phase operation is also possible. Please check our datasheets to see which models have paralleling, three phase and split phase capabilities.

Remote Monitoring & Control

When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Quattro and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Quattro to auto starting a backupgenerator and more.
