Victron Energy MultiPlus Compact 12/2000/80-50 120V VE.Bus (UL 458) – CMP122200102

mpervans, cabins and off-grid installations designed around a 120V AC supply.

With a nominal inverter rating of 2000VA and continuous active power of 1600W at 25°C, it can operate a range of compatible electrical appliances and equipment. The suitability of individual loads depends on their continuous power consumption, starting current and the inverter's operating limits.

The integrated transfer switch enables automatic changeover between an external AC source and inverter power. This is particularly useful in mobile and marine applications where shore power or a generator may be available intermittently.

Important: This is a 120V AC model intended for compatible electrical systems. It is not the standard 230V AC version commonly used in the UK. Confirm the required AC voltage, frequency and applicable electrical certification before purchasing.

Pure Sine Wave Inverter

The integrated inverter produces a pure sine wave AC output designed to provide stable power for compatible electronic equipment and appliances. It has a nominal output rating of 2000VA and delivers up to 1600W of continuous active power at 25°C.

The unit operates from a nominal 12V DC battery supply, with an input voltage range of approximately 9.5–17V DC. Its 120V AC output is intended for equipment designed for the appropriate electrical standard.

The inverter can supply connected loads from the battery when external AC power is unavailable. Correct battery capacity and cabling are important because higher AC loads can require substantial current from a 12V battery bank.

Adaptive 80A Battery Charger

The built-in adaptive battery charger provides charging current of up to 80A for a compatible 12V battery bank. Its multi-stage charging process is designed to recharge batteries efficiently while supporting suitable absorption and float charging stages.

When connected to an appropriate external AC supply, the MultiPlus Compact can charge the battery bank while supplying connected AC loads. Charging parameters must be configured for the battery chemistry and according to the battery manufacturer's requirements.

The charger is suitable for properly designed battery systems where the charging current, cable sizes, protective devices and available AC input power have been assessed for the installation.

PowerControl and PowerAssist

PowerControl helps prevent a limited external AC supply, such as a generator or shore-power connection, from becoming overloaded. When the available input current approaches its configured limit, the MultiPlus can reduce battery charging current to leave more capacity for connected AC loads.

PowerAssist adds another level of support by using available battery power through the inverter to supplement a limited AC source when demand temporarily exceeds the configured input limit. This can help manage short periods of increased electrical demand without requiring a larger external supply.

These functions are especially useful in marine and mobile installations where shore-power connections and generators may have limited capacity.

Uninterruptible Power Supply Function

When external AC power fails or is disconnected, the MultiPlus Compact automatically switches to inverter operation. The transfer typically takes less than 20 milliseconds, helping maintain the supply to compatible equipment and reduce disruption to sensitive electronics.

The effectiveness of this function depends on correct system configuration, battery condition and the electrical characteristics of the connected loads.

VE.Bus Communication and System Integration

The VE.Bus communication interface allows the MultiPlus Compact to communicate with compatible Victron Energy equipment. With suitable accessories and configuration, it can be integrated into systems supporting remote monitoring, configuration and control.

Multiple compatible units can be configured for increased output or supported split-phase and three-phase arrangements, subject to the manufacturer's requirements. Units must be suitable for the intended configuration; different MultiPlus models should not be assumed to operate together in parallel.
