MultiPlus 48/1600/20-16

The Victron Energy MultiPlus 48/1600/20-16 is an all-in-one solution designed for energy management. It combines a pure sine wave inverter, a sophisticated battery charger, and a fast AC transfer switch in a compact enclosure. It is ideal for standalone and grid-connected systems, providing reliable power and intelligent battery management.

This MultiPlus model delivers a continuous power output of 1600 VA (Volt-Amperes), equivalent to 1300 W (Watts) at an ambient temperature of 25 °C. It can power a wide range of sensitive electronic equipment.

The MultiPlus 48/1600/20-16 provides an AC output voltage of 230V AC with an accuracy of ± 2% and a frequency of 50 Hz. This ensures a stable and high-quality power supply for your devices.

The no-load consumption of the MultiPlus 48/1600/20-16 is approximately 3 W in standby mode and 10 W in normal operating mode without a connected load, depending on the operating mode.

The integrated battery charger uses a 4-stage adaptive charging algorithm: bulk (rapid charge), absorption (equalization charge), float (trickle charge), and storage. This microprocessor-controlled system adapts to battery usage to optimize the charging process and extend battery life.

The MultiPlus 48/1600/20-16 has a maximum charging current of 20A for batteries. This current is managed by the adaptive charging algorithm to ensure efficient and safe charging.

No, this MultiPlus model does not have a secondary output for a starter battery. This feature is specifically reserved for the 12V and 24V models in the MultiPlus range.

The UPS function of the MultiPlus ensures uninterrupted power supply to connected devices. In the event of an AC power failure (mains or generator), the MultiPlus switches to inverter mode in less than 20 milliseconds, ensuring that computers and other sensitive electronic equipment are not disrupted.

PowerControl: This function limits the maximum current the MultiPlus can draw from a limited AC source (such as a dock or generator). It adjusts battery charging current based on other power consumers to prevent overloading the AC source.
PowerAssist: This function extends PowerControl by allowing the MultiPlus to supplement the AC source’s power with battery energy during peak loads. When load decreases, excess power is used to recharge the battery, enabling the use of high-power devices with a limited AC source.

The MultiPlus is equipped with comprehensive electronic protection to ensure system safety and durability. This includes protection against short circuits, overloads, abnormal battery voltages (too high or too low), high temperatures, and excessive input ripple.

The MultiPlus adaptive charging algorithm operates in four main stages:

Bulk (bulk charge): The battery is charged at maximum current until a predefined voltage level is reached.
Absorption: The battery is charged at a constant, higher voltage while the current gradually decreases. The duration of this stage is variable to prevent overcharging and excessive gassing.
Float (float charge): The voltage is reduced to a maintenance level to compensate for the battery's self-discharge.
Storage: If the battery is not discharged for 24 hours, the float voltage is further reduced to minimize gassing and corrosion, with a weekly rise back to the absorption level to equalize the battery.

Yes, the MultiPlus is perfectly suited for solar energy applications. It can be integrated into standalone systems as well as grid-connected systems, allowing the use of solar energy to recharge batteries and power equipment, even in the event of a grid failure.

Yes, this MultiPlus is compatible with parallel and three-phase operations. You can connect up to six units in parallel to increase the total system power. It is also possible to configure three units for a three-phase output.

Yes, MultiPlus models with a 16A transfer capacity, like this one, are equipped with an analog/digital input/output port that can be used for communication with the BMS (Battery Management System) of a lithium-ion battery, ensuring optimal and secure battery management.

Yes, this MultiPlus model, with its 16A transfer capacity, is equipped with a programmable relay. This relay is factory-set as an alarm relay but can be configured for other applications, such as a generator start relay. It also features an analog/digital input/output port.

During installation, it is imperative to read the installation manual carefully. The product is a Class I safety appliance and must be continuously grounded. Ensure that connection cables are fitted with appropriate fuses and circuit breakers. Always disconnect AC power and the battery before any maintenance. Never use the product in environments where gas or dust explosions could occur.

Yes, it is crucial to ensure adequate ventilation around the MultiPlus. Make sure there is always sufficient free space around the product for ventilation and that the ventilation openings are not blocked. Install the product in a heat-resistant environment, away from chemicals, plastics, curtains or other textiles.

To compensate for voltage loss due to cable resistance, the MultiPlus features a voltage sensing function. This function measures the voltage directly on the DC bus or at the battery terminals, ensuring the correct charging voltage is applied to the battery regardless of voltage drop in the cables.
