Victron Energy Quattro-II 24/5000/120-50/50 230V Inverter Charger – QUA242505010

Product Description

The Victron Energy Quattro-II 24/5000/120-50/50 VE.Bus Inverter Charger (QUA242505010) is a high-performance combined inverter and battery charger designed for off-grid solar systems, marine electrical installations, motorhomes and backup power applications.

Combining a pure sine wave inverter, an integrated 120A battery charger and an automatic transfer switch, the Quattro-II provides a comprehensive power management solution for 24V battery systems. Its two independent AC inputs allow connection to separate power sources, such as shore power and a generator, with automatic selection of the available supply.

With a 5,000VA inverter rating and 4,000W continuous output at 25°C, the Quattro-II is designed for installations requiring substantial inverter capacity alongside intelligent battery charging and AC source management.

Key Features and Benefits

• 5,000VA inverter capacity: Delivers pure sine wave 230V AC power for compatible appliances and electrical equipment.

• 120A battery charger: Provides high-current charging for compatible 24V battery banks.

• Dual AC inputs: Automatically selects between two independent AC power sources.

• 50A transfer switch: Supports AC source transfer within the unit's rated operating limits.

• PowerControl: Limits AC input demand by managing battery charging current.

• PowerAssist: Supplements a limited generator or shore power supply with battery power when required.

• Automatic changeover: Transfers connected loads to inverter power when the AC supply fails.

• Two AC outputs: The main output provides continuity of supply, while the auxiliary output can supply loads only when an AC source is available.

• VE.Bus communications: Supports system configuration, compatible remote control and integration with other Victron equipment.

• Parallel and three-phase capability: Supports appropriately configured multi-unit installations.

• Remote monitoring: Can be integrated with compatible GX devices for local monitoring and access to the Victron Remote Management (VRM) platform.

Applications and Intended Use

Off-Grid Solar and Battery Systems

Converts energy stored in a compatible 24V battery bank into 230V AC electricity for household appliances, lighting, tools and other suitable electrical loads. It can be integrated with compatible solar charge controllers and battery storage equipment.

Marine and Boat Electrical Systems

Provides inverter power and battery charging for larger onboard electrical systems. The two AC inputs allow automatic selection between shore power and a generator, making it suitable for appropriately designed marine installations.

Motorhomes and Campervans

Supplies 230V AC power from a 24V battery system for compatible onboard appliances and electrical equipment when away from a mains connection.

Backup Power Installations

Provides automatic transfer to battery-powered inverter operation when the normal AC supply fails, helping maintain power to compatible connected equipment.

Commercial and Remote Properties

Suitable for workshops, remote buildings and other installations requiring substantial inverter capacity, battery charging and automatic management of AC power sources.

Hybrid Energy Systems

Can be incorporated into a professionally designed system combining battery storage, solar generation, generator power and compatible Victron monitoring and control equipment.

Installation and Compatibility

The Quattro-II 24/5000 is designed for integration into a correctly engineered 24V DC electrical system. Battery capacity, cable sizing, protective devices, earthing, ventilation and AC distribution must be selected to suit the installation and expected loads.

The two AC inputs can be connected to independent supplies, such as a generator and shore power. The unit automatically selects the appropriate active source according to its operating configuration.

VE.Bus connectivity supports integration with compatible Victron products and multi-unit systems. A compatible GX device can provide additional monitoring and control functions, including remote access through VRM.

Battery charging settings must be configured for the battery chemistry and manufacturer's requirements. Installation and commissioning should be completed by a suitably qualified professional in accordance with the manufacturer's instructions and applicable electrical regulations.
