CHARGER-INVERTER (Victron Quattro) 48/230V 100A 5kVA

The Victron Quattro charger-inverter 48 V, 70 A, 5000 VA is a combination of a 48 V, 5000 VA inverter and a battery charger.

The integrated battery charger provides up to 70 A charge current for the house battery.

The 48 V inverter converts the DC battery voltage into 230 VAC. Due to a pure sine wave output, this inverter is suitable for sensitive electronic devices.

The Quattro features two independent AC inputs with an integrated automatic transfer switch. It automatically connects to the active AC source (grid or generator). In case of AC failure, the unit switches to inverter mode in less than 20 milliseconds.

Features:

• true sine wave inverter
• two independent AC inputs with automatic source selection
• two AC outputs (main uninterrupted output + auxiliary output active only when AC input available)
• PowerControl to prevent overload of generator or grid supply
• PowerAssist to supplement weak AC sources with battery power
• parallel operation capability
• three-phase system configurable with three Quattro units
• programmable relay (alarm, DC undervoltage, generator start/stop)
• remote monitoring and control via GX device and VRM portal

Read the manual before installation and use. Additional documentation, including backup sizing and configuration guides, is available on your logistical knowledge base.

The Quattro can be used in both off-grid and grid-connected systems. It supports generator and grid input management through its two independent AC inputs. It is not intended for installations designed to feed energy back into the public grid.

Only qualified personnel should install and operate the unit.
Read carefully the safety and installation sections before use.

Verify DC and AC wiring before powering. Ensure fuses, circuit breakers, and grounding are correctly installed.

The unit automatically selects the active AC source (AC input 1 or AC input 2). In case of AC input failure, the unit switches to inverter mode with minimal interruption (<20 ms).

Configuration and monitoring can be done via the VE.Bus interface using Victron configuration tools or a GX device.
An MK3-USB adapter is required to connect to a computer.

When connected to a GX device and the Internet, the system can be monitored and controlled remotely via the VRM Portal.

If a fault occurs (overload, temperature, or voltage issue), the unit stops and indicates the fault via LED code. Identify and correct the cause before restarting.

Perform an annual inspection: tighten terminals, verify ventilation, and clean dust. Avoid exposure to moisture or heat sources.

Never open the enclosure. There are no user-serviceable parts inside. Contact authorized service if repair is required.
