Product Description

Victron Multi Inverter Charger 48V / 800VA /9A Battery Charger with 16A AC Transfer Switch, 5 Year Warranty. The new style MultiPlus is set to replace the earlier MultiPlus Compact range. It is a powerful true 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 to the connected loads. This 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.

Proven reliability:

The full bridge plus toroidal transformer topology has proven its reliability over many years. The inverter is short circuit proof and protected against overheating, whether due to overload or high ambient temperature.

PowerControl - Dealing with limited generator, shore side or grid power (800VA/1200VA):

With the Multi Control Panel a maximum generator or shore current can be set. The MultiPlus 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):

Where peak power is so often required only for a limited period, the MultiPlus will make sure that insufficient shore or generator power is immediately compensated for by power from the battery. When the load reduces, the spare power is used to recharge the battery.

High start-up power:

Needed to start high inrush loads such as power converters for LED lamps, halogen lamps or electric tools.

Search Mode:

When Search Mode is ‘on’, the power consumption of the inverter in no-load operation is decreased by approx. 70%. In this mode the Multi, when operating in inverter mode, is switched off in case of no load or very low load, and switches on every two seconds for a short period. If the output current exceeds a set level, the inverter will continue to operate. If not, the inverter will shut down again.

Programmable relay:

By default, the programmable relay is set as an alarm relay, i.e. the relay will de-energise in the event of an alarm or a pre-alarm (inverter almost too hot, ripple on the input almost too high, battery voltage almost too low).

Remote on / off / charger on:

Three pole connector.

Product Q&A

Ask Us a Question
  • Can these chargers take solar input?

    No, the battery charging component is an AC input, meaning only AC power (mains power) can charge through this unit. 

  • What size generator should I use for charging a battery?

    The below generators are the minimum recommend sizes based on an AVR generator:

    800VA 2KVA

    1200VA 2.5KVA

    1600VA 3KVA

    3000VA 5KVA

    5000VA 8KVA

    If your generator is smaller than the recommended size for your inverter/charger, you will definitely need to adjust the settings on the inverter/charger and reduce the AC input current limit, and/or a DC charge current limit to prevent overloading the generator. If you do want an inverter based generator get one that is at least 30% larger than required than an equivalent AVR based model to help prevent overloads. 

  • How can I remotely monitor and control my devices?

    You need a GX device to get remote monitoring. We recommend the Cerbo GX and an RJ45 UTP cable to connect it to the inverter. You can hardwire an ethernet connection to the unit, or connect it to a Wifi signal.
