MultiPlus 12 / 3000 120-50

The MultiPlus 12/3000/120-50 is an advanced device that integrates a voltage converter with a battery charger, offering the highest levels of reliability and performance. With its compact design, UPS functionality, and compatibility with a variety of battery types (GEL, AGM, LiFePO4), the MultiPlus is the ideal choice for users seeking a comprehensive power management solution for recreational vehicles, off-grid systems, and industrial applications.

Advanced Converter Technology

The MultiPlus combines a converter and charger, offering 12V voltage and 3000VA power. The device is equipped with a 120A charger, ensuring fast charging of batteries, regardless of their type. UPS (Uninterruptible Power Supply) guarantees continuity of power supply in the event of a sudden power outage, which is crucial in situations where interruption of the operation of electronic devices is unacceptable.

Compact Housing and High Performance

The MultiPlus is distinguished by its metal housing type Compact, which not only ensures high durability but also enables easy installation even in confined spaces. Its compact dimensions (362 x 258 x 218 mm) make it an ideal solution for installation in campers, boats, and industrial installations. Despite its small size, the device offers a powerful 3000VA of power, allowing for stable power supply to even the most demanding devices.

Innovative Energy Management Features

The MultiPlus is more than just a standard inverter. Thanks to its function PowerAssist, the system automatically adjusts charging power to avoid overloading the grid or generator. When energy demand increases, the MultiPlus increases output power by using the energy stored in the battery, allowing for more efficient management of available resources.
Remote control and monitoring is another advantage of this system. After integration with the device GX (e.g. Cerbo GX) it is possible to monitor and control MultiPlus from anywhere in the world thanks to the application VRM Whether you're at home or halfway around the world, you can fully manage your energy system.

Parallel and Three-Phase Operation

The MultiPlus offers parallel operation—up to six units can work together to provide greater output. Additionally, the device can operate in three-phase mode, making it a versatile solution for both small installations and large power systems. This flexibility allows the MultiPlus to be tailored to a variety of user needs.

Energy Optimization with Photovoltaics

The device works seamlessly with photovoltaic systems, allowing for maximum utilization of solar energy. Thanks to an advanced energy management algorithm, every unit of electricity is optimally utilized, resulting in savings and system efficiency. For those using renewable energy, the MultiPlus is the perfect complement to a solar system.

Reliability and Durability

The MultiPlus is a device you can rely on even in the most demanding conditions. Thanks to its robust design and innovative technologies, its failure rate is minimal. The device operates flawlessly across a wide temperature range – from -40°C to +65°C – making it suitable for use in almost any climatic conditions. Additionally, the intelligent battery management system maximizes battery life.
