CHARGER-INVERTER (Victron Multiplus) 24/230V 120A 5kVA

The Victron Multiplus charger-inverter 24 V, 120 A, 5000 VA is a combination of an 24 V, 5000 W inverter and a battery charger. The integrated battery charger provides up to 120 A charge current which allows quick charging even for bigger batteries as long as there is an AC input.

The 24 V sine inverter converts the DC battery voltage into 230 VAC. Due to a pure sine wave this inverter is also suitable for sensitive electronic devices.
An integrated relay switches over from AC input to inverter output. And it switches back when power is restored at the input. The whole process is controlled fully automatic.

Features:

• true sine wave inverter
• adaptive charging, 3-stage (bulk, absorption and float)
• PowerAssist with overload prevention of a limited AC source and AC power boost with power taken from the battery
• offline UPS configurable, i.e. short switch over time (20 milliseconds) and a true sine wave output
• virtual unlimited power in parallel operation of multiple Multiplus
• 3-phase system configurable with 3 Multiplus devices
• remote monitoring and control, connection with VRM portal from Victron

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

The MultiPlus can be used in both off-grid and grid-connected systems. It supports AC-coupled operation with grid-tie inverters. However, 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.

Switch the front selector to ON for normal operation, or Charger only when charging is needed without inversion.

In case of AC input failure, the unit automatically switches to inverter mode with minimal interruption (<20 ms).

Configuration and monitoring can be done via the VE.Bus interface using VictronConnect, VE.Configure, or a GX device.
An MK3-USB adapter is required to connect to a computer.
When connected to a GX controller, the unit can access the Internet and the VRM Portal for remote monitoring and maintenance.

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.
