MultiPlus 12/3000/120-16

The MultiPlus 12/3000/120-16 is a complete energy solution from Victron Energy. It combines three essential functions in a single compact housing: a 3000 VA pure sine wave inverter, a 120-amp adaptive battery charger, and a 16-amp high-speed AC transfer switch.

The MultiPlus 12/3000/120-16 inverter provides a continuous output power of 3000 VA, which is equivalent to 2400 Watts when the ambient temperature is 25°C.

The MultiPlus 12/3000/120-16 can deliver a peak power of 6000 Watts. This capacity is particularly useful for starting equipment that requires a high inrush current at startup.

The MultiPlus 12/3000/120-16 operates from a 12V DC input voltage (with an operating range of 9.5 to 17V). It provides a 230V AC output at ±2% with a frequency of 50 Hz ±0.1%.

The PowerControl function allows you to set a maximum AC input current to prevent overloading limited power sources, such as a generator or shore power connection. The MultiPlus will account for other AC loads and only use the available excess current for battery charging, thereby protecting the power source.

The PowerAssist function goes beyond PowerControl by allowing the MultiPlus to supplement AC power with battery power during peak consumption. This prevents tripping and enables the use of lower-ampere generators or shore power outlets. When the load decreases, the excess energy is used to recharge the battery.

Yes, the MultiPlus 12/3000/120-16 includes a UPS (Uninterruptible Power Supply) function. In the event of a power outage, its 16A automatic transfer switch ensures uninterrupted AC power within 20 milliseconds, guaranteeing continuous operation of sensitive equipment.

The MultiPlus 12/3000/120-16 integrated charger can deliver a powerful charging current of 120 amperes for the main service battery.

Yes, in addition to the main output for the service battery, the MultiPlus has a second output dedicated to trickle charging a starter battery. This output is limited to 4 amperes.

Search Mode is a function that significantly reduces the inverter's power consumption when there is no load or a very light load. In this mode, standby consumption is reduced to about 8 Watts, as the inverter periodically shuts down and restarts to detect if a load is present.

The MultiPlus uses an adaptive four-stage battery management system (bulk, absorption, float, storage) controlled by a microprocessor. This charging software automatically refines the process to adapt to the battery's state, optimizing its lifespan and preventing overcharging or undercharging.

Yes, the MultiPlus is perfectly suited for solar energy applications. It can be integrated in both standalone systems and grid-connected systems, using excess solar energy to recharge batteries.

The adaptive charger of the MultiPlus 12/3000/120-16 is compatible with a wide range of battery types, including lithium-ion, sealed, AGM, gel, and flooded batteries.

Yes, the MultiPlus supports parallel operation. Up to six MultiPlus units can be connected together to achieve a combined higher output power, suitable for high energy requirements.

Yes, it is possible to configure three MultiPlus units to provide a three-phase output. For even more powerful systems, up to six sets of three units can be connected in parallel.

After installation, basic settings can be adjusted using DIP switches. For advanced configuration, you can use the VictronConnect app or the VE-Configure software with the MK3-USB interface. Remote monitoring is possible by connecting a GX device (such as a Cerbo GX or Ekrano GX) to the VRM portal.

Yes, the MultiPlus 12/3000/120-16 is equipped with a programmable relay. By default, it is configured as an alarm relay, but it can be reprogrammed for various other applications, such as starting or stopping a generator.

Yes, by connecting a GX product (such as a Cerbo GX or Ekrano GX) to the internet, the MultiPlus’s operational data can be stored and displayed on the free VRM (Victron Remote Management) portal. This enables full remote monitoring and configuration of your system.

The MultiPlus is a Class I safety device and requires continuous grounding for safety reasons. It is imperative to ensure that the connection cables are equipped with appropriate fuses and circuit breakers. The installation must be carried out in a heat-resistant environment with sufficient space for adequate ventilation.

The MultiPlus features a voltage sense function. This function compensates for voltage losses caused by cable resistance by measuring the voltage directly at the battery terminals or on the DC bus, ensuring the correct charging voltage is always applied to the battery.
