Victron Energy MultiPlus-II 12/3000/120-32 Inverter/Charger

£1,288.00

The Victron Energy MultiPlus-II 12/3000/120-32 Inverter/Charger delivers powerful all-in-one performance by combining a 3000VA pure sine wave inverter, a 120A adaptive 4-stage battery charger, and a 32A high-speed AC transfer switch in a single compact unit. Victron designed this system for reliability and efficiency, making it ideal for space-limited installations where reducing components and wiring matters.

Key Features:

3000VA Pure Sine Wave Inverter
The inverter converts 12V DC into 230V AC mains power, delivering up to 2400W continuous output and 5500W peak power. As a result, it runs appliances such as TVs, laptops, and fans with ease, while at the same time the pure sine wave output protects sensitive electronics and, in addition, maximises efficiency.
120A Smart Battery Charger
The integrated 4-stage adaptive charger (Bulk, Absorption, Float, Storage) actively adjusts charging based on battery type and usage. This approach ensures safe, efficient, and unattended battery charging.
Uninterruptible Power Supply (UPS) Function
In addition, the 32A high-speed AC transfer switch seamlessly switches to inverter power in under 20 milliseconds during a grid failure or power loss, thereby keeping critical devices running without interruption.
Why Choose the Victron MultiPlus-II?
  • Space-saving design – Combines multiple power functions in one compact unit
  • Proven Victron build quality – Delivers long-term reliability and performance
  • Simplified installation – Reduces wiring complexity and the need for additional components
As a result, it is ideal for off-grid systems, backup power, marine, and RV applications; moreover, the MultiPlus-II 12/3000/120-32 delivers efficient energy conversion and dependable power whenever you need it.
Additional intelligent features:
The MultiPlus-II includes all the features of the standard MultiPlus inverter/chargers and adds support for an external current sensor, which extends the PowerControl and PowerAssist functions up to 50A and improves self-consumption (external current sensor not included).
In addition, the MultiPlus-II provides an auxiliary AC output (AC-out-2) for non-critical loads. Equipment connected to AC-out-2 operates only when AC input voltage is available and disconnects instantly when the MultiPlus-II switches to battery (inverter) mode.

Description

Advanced Features and Customisable Functions:-

PowerControl

PowerControl allows you to set the maximum AC input current for both battery charging and AC loads. The MultiPlus-II prioritises appliances first and uses remaining power to charge the batteries. This prevents overloading limited AC sources, such as generators or shore power, and avoids tripping circuit breakers. The Multi Control Panel is required (not included).

PowerAssist

In addition, PowerAssist allows the MultiPlus-II to boost a limited AC power source. Whenever connected appliances demand more current than the AC supply can deliver, the unit draws additional power from the battery and operates in parallel with the AC input. Once demand decreases, the system redirects surplus AC power back into battery charging. Consequently, this feature enables the use of smaller generators and maximises available shore power.

Programmable Relay

Furthermore, the built-in programmable relay supports a wide range of applications, including generator start/stop control. By default, the relay acts as an alarm relay and de-energises during alarms or pre-alarms such as high inverter temperature, excessive input ripple, or low battery voltage.

Parallel and 3-Phase Operation

Equally important, you can connect up to six identical MultiPlus-II units in parallel to increase output power. At the same time, the system supports three-phase (Y configuration) operation. For these setups, a standard RJ45 UTP cable is required (not included).

Comprehensive Safety Protection

To ensure reliable operation, the MultiPlus-II actively protects against output short circuits, overloads, battery overvoltage and undervoltage, overheating, external AC voltage appearing on the inverter output, and excessive input voltage ripple.

WeakAC Mode

When AC quality is poor, WeakAC mode allows the charger to continue operating with heavily distorted input voltages. Although this increases input current distortion, it ensures uninterrupted charging under challenging conditions.

BatterySafe Mode

Additionally, BatterySafe mode prevents excessive gassing during fast charging by limiting the voltage rise once the gassing threshold is reached, thereby protecting overall battery health.

Storage Mode

After 24 hours without battery discharge, Storage Mode activates automatically. At this stage, the system lowers float voltage to reduce gassing and corrosion and then periodically raises voltage to absorption level. This process helps prevent electrolyte stratification and sulphation—two major causes of premature battery failure.

Bulk Protection

As an added safeguard, Bulk Protection limits bulk charging time to 10 hours, helping detect system faults such as internal battery short circuits.

Temperature Compensation

Meanwhile, the included temperature sensor adjusts charge voltage as battery temperature rises, preventing overcharging—particularly important for maintenance-free batteries.

Remote Monitoring and Control

Finally, when paired with a GX device such as Cerbo GX, you can monitor and control the MultiPlus-II locally via LAN/Wi-Fi or remotely through the VRM app or VRM portal. This allows access from a phone, tablet, laptop, or PC anywhere in the world.
