Victron Energy MultiPlus 2000VA Inverter/Charger, 120V, VE.Bus

Overview

The Victron Energy MultiPlus 2000VA 120V is an inverter and battery charger in one unit for boats that need 120 VAC power from a 12 V or 24 V battery bank. It combines a true sine wave inverter, adaptive battery charging, and a 50 A AC transfer switch, which makes it useful for systems that move between shore power, generator power, and battery power.

In inverter mode, the MultiPlus 2000VA range delivers 120 VAC at 60 Hz, with 2000 VA output power, 1600 W continuous output at 25°C, and 3500 W peak power for short inrush loads. The two configurations cover either 12 V or 24 V battery systems, so the correct version should match the vessel’s house battery voltage.

The enclosure is steel with an IP22 rating, so it belongs in a dry, protected location with airflow, such as an electrical locker, cabin technical space, or other sheltered area away from direct spray. Its VE.Bus communication port supports monitoring, configuration, and integration with other Victron system components.

Key features

• True sine wave inverter output for 120 VAC onboard loads that need clean AC power.
• Adaptive battery charger with up to 80 A charging on the 12 V version or up to 50 A charging on the 24 V version.
• 50 A transfer switch for moving AC loads between shore or generator input and inverter output.
• PowerControl and PowerAssist help manage limited dockside or generator capacity by reducing charge demand and supplementing power from the battery when needed.
• VE.Bus communication port for parallel operation, three-phase configuration, remote monitoring, and system integration.
• Remote on-off connection and DIP switches for basic setup after installation.
• Starter battery trickle charge output rated at 1 A on the 12 V and 24 V models.
• Operating temperature range from -40°C to +65°C with fan-assisted cooling and a maximum non-condensing humidity rating of 95%.
• Steel enclosure with IP22 protection, M8 battery connections, and screw terminals for AC wiring up to 13 mm² or 6 AWG.
• Common chassis size of 506 x 236 x 147 mm and weight of 15.5 kg across the 12 V and 24 V versions.

Variants

This MultiPlus 2000VA 120V range is offered in two configurations for different house battery voltages.

The battery voltage and house battery charge current are the key differences between the variants. Both versions share the 2000 VA inverter class, 120 VAC output, 50 A transfer switch, VE.Bus communication, IP22 steel enclosure, dimensions, and 15.5 kg weight.

• PMP122200102: 12 V battery version with 80 A charge current. This configuration matches 12 V house battery banks and uses a 9.5 to 17 VDC input voltage range.
• PMP242200102: 24 V battery version with 50 A charge current. This configuration matches 24 V house battery banks and uses a 19 to 33 VDC input voltage range.

Electrical and system integration

The MultiPlus can take AC input from shore power or a generator, charge the battery bank, and supply onboard AC loads through its inverter when the outside AC source is not available. Its UPS-style transfer behavior helps keep sensitive AC loads running during brief changes in shore or generator supply, provided the installation and load planning are correct.

For more involved Victron installations, the VE.Bus connection allows the inverter/charger to work with monitoring and control hardware such as GX devices, VE.Bus Smart Dongle, Digital Multi Control, and MK3-USB interface tools. This is especially useful on cruising boats, fishing boats, and liveaboard systems where battery state, charging behavior, and AC source limits need regular attention.

Installation and fit

Plan the mounting location around the unit’s 506 x 236 x 147 mm size, 15.5 kg weight, DC cable routing, AC wiring access, and cooling airflow. Because the enclosure is IP22, it should not be mounted where it can be hit by washdown water, bilge spray, rain, or salt mist.

The battery connection uses M8 bolts, and the AC connection uses screw terminals. Cable size, overcurrent protection, battery isolation, ventilation, and grounding should be matched to the vessel’s electrical design and installed by a qualified marine electrician.

Use cases on board

This inverter/charger range suits vessels with a defined 12 V or 24 V house bank that need 120 VAC power away from the dock and controlled charging when shore power or generator power is available. It is a practical fit for onboard AC circuits serving galley equipment, tools, entertainment electronics, battery charging loads, or other properly sized AC equipment within the inverter’s output rating.
