PowerControl for the MultiPlus-II 48/4k5/55-32 230V

The inverter/charger is able to provide a very high charging current. This places a heavy load on the AC power supply or the generator. For this reason, a maximum current can be set. The inverter/charger then takes into account the consumption already present and only uses the "excess" current to charge the battery.

PowerAssist with MultiPlus-II 48/4k5/55-32 230V

This function adds a new dimension to the PowerControl principle, as the inverter/charger can support an alternative source that is too weak. Load peaks often only occur for a limited period of time. In such a case, the inverter/charger ensures that insufficient grid or generator power is immediately compensated for by energy from the battery. If the load is reduced, i.e. loads are switched off, the available energy can then be used to charge the batteries again.

Uninterruptible alternating current (UPS function)

In the event of a mains fault or if the shore power or on-board generator is interrupted, the Multis inverter is automatically switched on and takes over the supply to the connected loads. The switchover happens so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed.

ESS: Energy storage systems (home storage solutions)

The MultiPlus-II is a key component in an Victron ESS. It is very flexible and can be combined with an MPPT solar charger or a grid feed-in inverter for PV systems. Examples and further information can be found in the ESS (Energy Storage System) manual in the download area.

Ekrano GX, Cerbo GX MK2, GX Touch 50

In addition to system monitoring and control, the Cerbo GX MK2 or the Ekrano GX provide access to Victron's free remote monitoring website: the VRM Online Portal for intuitive remote system control and monitoring.

VRM - Victron Remote Monitoring

Monitor all energy systems, tanks and temperatures remotely. Control your systems with ease, dive deep into the data to maximise performance and detect problems early with push notifications. Victron's free Remote Monitoring (VRM) website allows you to view all of your system's data in a comprehensive graphical format. The portal allows you to make system changes remotely and receive alerts via email. Further information can be found in the manual in the download area.

System configuration, monitoring and control on site

The settings can be changed within a few minutes using the VEConfigure software via a computer or laptop. An MK3-USB interface or MK3-USB-C is required for this.

Several optional options are available for the monitoring and control options. Starting with the laptop, computer, GX devices such as the Venus GX, battery monitor or the Digital Multi control panel. The Digital Multi Control Panel is a practical and cost-effective solution for monitoring with a rotary knob to set the PowerControl and PowerAssist levels. It is available in two visually different versions, either as Digital MultiControl or as Digital Multicontrol GX.

A smartphone or other Bluetooth-enabled device can also be used. The optional VE.Bus Smart Dongle is required here. It measures the battery voltage and temperature and enables monitoring and control.

Widgets of the VRM app

With the VRM app (available for iOS and Android devices in the App Store and Google Play), you can monitor, control and manage your Victron Energy system from virtually anywhere in the world. Even if you use multiple systems, you can manage them via the app.

Thanks to the VRM widgets, you can immediately see all the important system, tank and temperature data without having to open the app first. Control your generator, energy storage system or electric vehicle charger directly from the home screen of your smartphone.

What are VRM app widgets?
Widgets are generally shortcuts that you can add to your home screen to quickly access information. Widgets are not only displayed on your home screen, but can also be displayed in the Today view by swiping right from the home screen or lock screen. Note that the widgets of the VRM app are not identical to those of the VRM portal. These are non-customisable phone widgets.

Further information can be found in the manual in the download area.

Standard maritime, mobile or off-grid application

Loads that are to be switched off when no AC input is available can be connected to a second output (not shown). These loads are taken into account by the PowerControl and PowerAssist function to limit the AC input current to a safe value when AC power is available.

Topology parallel to the grid with MPPT solar charge controller

The MultiPlus-II uses data from the external AC sensor (to be ordered separately) or electricity meter to optimise self-consumption and, if necessary, to prevent electricity from being fed into the grid. In the event of a power failure, the MultiPlus-II continues to supply the necessary loads.

Current sensor 100A: 50mA (optional) for MultiPlus-II

For implementing the PowerControl and PowerAssist functions and for optimising self-consumption with external current measurement. Maximum current: 50mA or 100A. Please note that there are two different types. One version has a plug and the other version has wire ends. Both versions are available with cable lengths of 1, 5 and 20 metres.
