Multi-Functional Inverter & Charger In 1 Unit

Victron MultiPlus Inverter/Charger

The Victron inverter/chargers have a wide range of features to suit almost any application. They combine powerful true sine wave inverters, sophisticated battery chargers and a high-speed AC transfer switch in a single compact enclosure.

Grid Connected Battery Back-up
The Victron Multiplus II range 48/3000 & 5000 (others to follow) will have G98 & G99 type approval together with compliant earth switching to allow you to store excess generation from grid connected PV & wind systems during the day for use at night. As a bonus you will also have backup power should the grid go down.

Victron MultiPlus Inverter/Charger

Multifunctional, with intelligent power management
The MultiPlus is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology, and a highspeed AC transfer switch in a single compact enclosure. Next to these primary functions, the MultiPlus has several advanced features, as outlined below.

Parallel operation and three phase capability
Up to six Multis can operate in parallel to achieve higher power output. In addition to parallel connection, three units can be configured for three-phase output.

PowerControl – Dealing with limited generator, shore side or grid power
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
This feature takes the principle of PowerControl to a further dimension. It allows the MultiPlus to supplement the capacity of the alternative source. 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.

Four stage adaptive charger and dual bank battery charging
The main output provides a powerful charge to the battery system by means of advanced ‘adaptive charge’ software. The software finetunes the three-stage automatic process to suit the condition of the battery, and adds a fourth stage for long periods of float charging. The adaptive charge process is described in more detail on the Phoenix Charger datasheet and on our website, under Technical Information. In addition to this, the MultiPlus will charge a second battery using an independent trickle charge output intended for a main engine or generator starter 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.

On-site system configuring, monitoring and control
After installation, the MultiPlus is ready to go.
Some settings can be changed with DIP switches.
500/800/1200VA models: remote switch / battery charge voltage / inverter frequency /search mode.
1600/2000VA models: battery charge voltage /search mode.
For more settings use VE-Config or the VE.Bus Smart dongle.

Remote configuring and monitoring
Install a Cerbo GX or other GX product to connect to the internet. Operational data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.
When connected to the internet, systems can be accessed remotely, and settings can be changed.
