MultiPlus C 12/1600/70-16

The Victron Energy MultiPlus C 12/1600/70-16 is a compact and versatile device that combines three essential functions:

A pure sine wave inverter to convert DC from batteries to AC power.

An adaptive battery charger to optimize charging and battery lifespan.

An ultra-fast AC transfer switch to switch between power sources without interruption.

It is designed for marine applications, recreational vehicles, and standalone power systems.

The MultiPlus C 12/1600/70-16 delivers a continuous output power of 1600 VA (equivalent to 1300 W) at 25°C. Its peak power is 3000 W.

The integrated adaptive battery charger has a capacity of 70 A, enabling efficient and optimized charging of your batteries.

This model is compatible with 12 V DC battery systems. It accepts a DC input voltage range from 9.5 V to 17 V.

Yes, the MultiPlus C 12/1600/70-16 includes UPS (Uninterruptible Power Supply) functionality. In the event of a power outage or AC source failure, the inverter takes over in under 20 milliseconds, ensuring uninterrupted AC power supply to connected devices.

The PowerAssist function allows the MultiPlus to supplement the capacity of a limited AC source (such as a generator or shore power outlet). If power demand exceeds the AC source's capacity, the MultiPlus uses battery energy to provide the additional power required. When the load decreases, the excess power is used to recharge the battery.

The PowerControl function allows you to set a maximum current that the MultiPlus can draw from a limited AC source (such as a shore power outlet or a generator). The device takes into account other energy consumers and only uses the 'excess' current for battery charging, thereby preventing overload of the AC source.

The adaptive battery management system, microprocessor-controlled, can be adjusted for various battery types, including lead-acid batteries (flooded, gel, AGM) and Lithium-Ion batteries. The adaptive function automatically adjusts the charging process to the battery's usage.

Yes, in addition to the main DC terminal that can supply the full output current, there is a second output. This output is specifically intended for charging a starter battery and is limited to 4 A, with a slightly lower output voltage.

The MultiPlus C 12/1600/70-16 comes with a temperature sensor. This sensor automatically reduces the charging voltage as battery temperature rises. This feature is critical to prevent overcharging and battery dry-out, especially for maintenance-free batteries, thereby extending their lifespan.

The maximum efficiency of the MultiPlus C 12/1600/70-16 inverter reaches 93%, ensuring optimized energy conversion and minimized losses.

Yes, the MultiPlus C 12/1600/70-16 is perfectly suited for solar energy applications. It can be used in both standalone systems and grid-connected systems, allowing excess solar energy to be stored in batteries and released as needed.

The adaptive charger uses a 4-stage charging algorithm to optimize battery health and lifespan:

Bulk (bulk charge): Charges the battery at its maximum current.Absorption: Maintains a constant voltage to fully charge the battery, with a variable duration depending on the initial discharge level.Float (float charge): Maintains the battery at a lower float voltage to compensate for self-discharge.Storage: Reduces the float voltage to minimize gassing and corrosion when the battery is not used for 24 hours, with weekly equalization.

Models with a 16 A transfer capacity, such as the MultiPlus C 12/1600/70-16, are equipped with a programmable relay. By default, it is configured as an alarm relay, but it can be programmed for various other applications, for example as a start relay for a generator.

The 'Storage' mode activates when the battery has not been discharged for 24 hours. In this mode, the float voltage is reduced to 2.2 V/cell (13.2 V for a 12 V battery) to minimize gassing and corrosion of the positive plates. Once per week, the voltage is raised to the absorption level to 'equalize' the battery, preventing electrolyte stratification and sulfation—major causes of early battery failure.

Before any installation, it is imperative to read the provided manual. General precautions include:

Always disconnect AC power and the battery before any intervention.Ensure the device is continuously grounded, as it is a Class I safety device.Check that connection cables are equipped with appropriate fuses and circuit breakers.Never use the product in environments where gas or dust explosions could occur.Any maintenance must be performed by qualified personnel.

The MultiPlus must be installed in a heat-resistant environment and in a space where there is always sufficient free space around the product for ventilation. It is crucial to ensure that ventilation openings are not blocked and that no chemicals, plastic parts, curtains, or other textiles are in the immediate vicinity of the equipment.

Yes, the MultiPlus C 12/1600/70-16 is a Class I safety device. Its AC input and/or output terminals must have a continuous ground connection for safety purposes. An additional grounding point is also located outside the product.

Yes, it is possible to configure three units for a three-phase output. Additionally, up to 6 sets of three units can be connected in parallel. This allows for inverter power up to 45 kW / 54 kVA and a charging capacity of over 1000 A.

Yes, the MultiPlus is supplied ready for use, but several methods allow you to modify its settings:

The most important settings can be modified simply using DIP switches. All settings (except the multifunction relay) can be modified with a VE.Net panel. All settings can be modified using a PC and free software downloadable from the Victron Energy website.
