Victron MultiPlus - 500VA to 2000VA

12/24/48V

The new style MultiPlus is set to replace the earlier MultiPlus Compact range. It is a powerful sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single compact enclosure.
 

Uninterrupted AC power (UPS function)

In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply of the connected loads. This action happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
 

Remote Monitoring and Control

Monitor and control your MultiPlus and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, via the required Color Control GX or Venus GX, from adjusting your MultiPlus to setting a Geofence for-hire vehicles and more...

Multifunctional

 The Multi gets its name from the multiple functions it can perform. It is a powerful sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single enclosure. Besides these primary functions, however, the Multi has several advanced features that provide a range of new applications as outlined below.

Uninterrupted AC power

 In the event of a grid failure, or shore or generator power disconnect, the inverter within the Multi is automatically activated and takes oversupply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.

Parallel and 3-phase operation capability

Up to 6 inverters can operate in parallel to achieve higher power output. Operation in 3-phase configuration is also possible.

PowerControl – Dealing with a limited generator or shore side power  (800VA, 1200VA, 1600VA and 2000VA models only)

A Multi Control Panel can set a maximum generator or shore current. The Multi will then take account of other AC loads and use whatever is extra for charging, thus preventing the generator or shore supply from being overloaded.

PowerAssist – Boosting the capacity of shore or generator power (800VA, 1200VA, 1600VA and 2000VA models only)

This feature takes the principle of PowerControl to a further dimension allowing the MultiPlus Compact to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period, it is possible to reduce the size of generator needed or conversely enable more energy from the typically limited shore connection. When the load decreases, the spare power is used to recharge the battery.

Programmable relay

The Multi is equipped with a programmable relay that by default is set as an alarm relay. The relay can be programmed for all kinds of other applications, however, for example as a starter relay for a generator.

Adaptive 4-stage charging characteristics: bulk – absorption – float – storage

The microprocessor-driven adaptive battery management system can be adjusted for various types of batteries. The adaptive function automatically adapts the charging process to battery use.

The right amount of charge: variable absorption time

In the event of slight battery discharge, absorption is kept short to prevent overcharging and excessive gas formation. After deep discharging, the absorption time is automatically extended in order to fully charge the battery.

Preventing damage due to excessive gassing: the BatterySafe mode

If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, damage due to excessive gassing will be prevented by automatically limiting the rate of voltage increase once the gassing voltage has been reached.

Less maintenance and aging when the battery is not in use: the Storage mode

The Storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In the Storage mode, float voltage is reduced to 2,2V/cell (13,2V for 12V battery) to minimise gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘equalize’ the battery. This feature prevents stratification of the electrolyte and sulphation, a significant cause of early battery failure.

Two DC outputs for charging two batteries

The main DC terminal can supply the full output current. The second output, intended for charging a starter battery, is limited to 1A and has a slightly lower output voltage.

Increasing service life of the battery: temperature compensation

The temperature sensor (supplied with the product) serves to reduce charging voltage when battery temperature rises. This is particularly important for maintenance-free batteries, which could otherwise dry out by overcharging.
