Description
Victron Quattro-II 12/3000 Inverter/Charger | Boat Supply Store
Addressing demanding electrical needs on North American 120/240V split-phase vessels, this unit integrates a high-capacity inverter and a robust charger. It delivers 3000VA continuous output power (2400W at 25°C) and features dual AC inputs for unparalleled source flexibility. The innovative PowerAssist technology effectively manages peak loads by drawing from battery power when shore or generator input is insufficient, ensuring critical systems remain operational, ideal for offshore cruising or extended anchoring.
Key Features
- Seamless Power with no-break transfer for uninterrupted operation of critical onboard electronics.
- Dual AC Input Versatility allowing connection to two independent AC sources for enhanced redundancy and flexibility.
- Peak Load Management via PowerAssist technology, drawing on battery power to supplement insufficient generator or shore power.
- High Charge Current of 120A to rapidly replenish battery banks from generator or shore power.
- Split-Phase Compatibility engineered for standard North American 50A 120/240VAC systems.
- Scalable Power Output through parallel and three-phase operation for increased energy demands.
- Comprehensive Monitoring and Control via on-site and remote options for complete system oversight.
- Wide Operating Temperature Range from -40 to +65°C ensuring reliable performance in extreme marine environments.

Common Concerns Answered
Is the setup complex for new users?
While Victron's VEConfigure software offers advanced customization, basic setup for standard North American 120/240V split-phase applications is well-documented. For complex configurations or to ensure optimal performance, professional installation is recommended.
What is the main difference in transfer times?
The Quattro-II features a no-break functionality on its main output with fast transfer times, ensuring critical loads remain powered. The auxiliary output's transfer time is longer, which is a consideration for systems with ultra-critical, instantaneous backup requirements on secondary circuits.
Is the premium price justified?
The Quattro-II's premium price reflects its advanced dual AC inputs, sophisticated PowerAssist technology, no-break transfer, and robust build quality designed for demanding marine environments. Its ability to seamlessly manage complex power sources and peak loads offers superior reliability and flexibility compared to simpler units.
Frequently Asked Questions
What is the primary difference between the Victron Quattro-II 2x120V and the MultiPlus-II 2x120V?
The primary difference lies in the AC inputs: the Quattro-II features dual AC inputs for connection to two independent sources (e.g., shore power and generator), offering superior source selection and redundancy, while the MultiPlus-II typically has a single AC input.
Can the Victron Quattro-II 2x120V power 240V loads?
Yes, the Quattro-II 2x120V is designed for North American split-phase systems and can output 240V loads by combining the two 120V legs, in addition to providing standard 120V power.
How does the PowerAssist function work on the Victron Quattro-II 2x120V?
PowerAssist dynamically supplements available AC source power with battery power when peak loads exceed the source's capacity. For example, if a generator is rated at 30A but the AC load momentarily demands 50A, PowerAssist will supply the additional 20A from the batteries to prevent overload.
What is the transfer time for the Victron Quattro-II 2x120V?
The transfer time for the main output is extremely fast, typically within 20 milliseconds, ensuring a virtually seamless transition between AC sources or from battery power to AC power, preventing interruption to most sensitive electronic equipment.
Can multiple Victron Quattro-II 2x120V units be connected in parallel or three-phase?
Yes, multiple Quattro-II 2x120V units can be connected in parallel to increase the total output power or in a three-phase configuration, providing significant power scalability for larger vessels or demanding applications.
