Victron 12V 2000VA MultiPlus 12/2000/80-32 Inverter/Charger

The Victron MultiPlus 12/2000/80-32 is a 12V to 230V pure sine wave inverter and battery charger, combining a 2000VA inverter, 80A adaptive battery charger and 32A automatic transfer switch in one unit. Designed for caravans, motorhomes, boats and off-grid power systems, it provides dependable AC power whether you're connected to shore power, running a generator or operating from your 12V battery bank.

With Victron's PowerControl and PowerAssist technology, intelligent battery charging and VE.Bus connectivity, the MultiPlus makes managing your off-grid electrical system easier while helping you get the most from your available power supply.

2000VA Pure Sine Wave Inverter

The MultiPlus produces clean, stable 230V AC power for compatible household appliances, electronics and equipment with electric motors. Its 2000VA rating provides 1600W of continuous output at 25°C, with up to 3500W of peak power to help manage short start-up surges.

Continuous output reduces to 1400W at 40°C and 1000W at 65°C. When selecting an inverter, it's important to consider both the running wattage and start-up requirements of your appliances, as 2000VA does not mean 2000W of continuous output.

Integrated 80A Battery Charger

When connected to a suitable external AC supply, the MultiPlus can recharge your 12V auxiliary battery bank at up to 80A. Its adaptive four-stage charging system manages bulk, absorption, float and storage stages to provide efficient charging while helping maintain battery health.

The charging parameters can be configured for compatible lead-acid and lithium battery systems, provided the correct settings and battery management requirements are followed.

An additional 1A charging output is provided for maintaining a compatible starter battery, while temperature-compensated charging helps protect suitable lead-acid batteries from excessive charging voltage.

PowerControl and PowerAssist

PowerControl helps prevent a limited shore power or generator supply from becoming overloaded. By setting an appropriate AC input current limit, the MultiPlus can prioritise connected appliances and automatically reduce battery charging when available power is limited.

PowerAssist goes a step further by temporarily supplementing the external AC supply with energy from your battery bank when demand exceeds the configured input limit. Once power demand decreases, the available capacity can be used to recharge the batteries.

These features are especially useful in caravans, motorhomes and off-grid installations where generator capacity or external power availability may be restricted.

Automatic AC Transfer Switching

The integrated 32A transfer switch automatically manages power between an external AC supply and the battery-powered inverter.

When shore power or generator supply is interrupted, the MultiPlus switches to inverter operation in less than 20 milliseconds under normal operating conditions. This allows many electronic devices to continue operating without interruption, provided the connected loads remain within the inverter's capacity.

When suitable external AC power returns, the unit can resume supplying connected loads and charging the battery bank.

Energy Saving Search Mode

Running an inverter continuously can consume battery power even when no appliances are operating. The MultiPlus features a configurable Search Mode that reduces consumption by placing the inverter into a low-power state when demand falls below a set threshold.

Normal no-load consumption is approximately 10W, reducing to around 3W in Search Mode. The inverter periodically checks for a sufficient load and resumes normal operation when required.

Victron Monitoring and System Integration

VE.Bus connectivity allows the MultiPlus to integrate with compatible Victron monitoring and control equipment. When connected to a GX device, such as the Cerbo GX, system information can be monitored locally or remotely through the Victron Remote Management (VRM) platform.

Bluetooth connectivity is available through the optional VE.Bus Smart Dongle. Bluetooth is not built into this model.

Additional configuration options include adjustable charging parameters, remote on/off control, programmable relay functions and compatible parallel or three-phase system configurations.

Important Installation Considerations

At high output, a 1600W inverter can draw well over 130A from a 12V battery system. Battery capacity, discharge capability, BMS limits, DC cable sizing, fusing, earthing and ventilation must all be considered when planning an installation.

The MultiPlus does not include an internal DC fuse, so appropriate external protection is required. It also does not include an MPPT solar charge controller. Solar charging requires separate compatible equipment.

This model has one main AC output and should not be confused with MultiPlus-II models featuring an additional auxiliary AC output. Australian grid-connected or grid-export applications require separate consideration of applicable approvals and standards.

Installation must follow Victron's instructions and applicable Australian electrical requirements, with AC electrical work completed by appropriately licensed personnel.
