Victron Energy MultiPlus 12V 500VA 20A (16A Transfer) Inverter/Charger


The Victron Energy Multiplus 12v 500VA / 20Amp Inverter / Charger is a fantastic piece of equipment.  With an appropriate battery supply the Victron Multiplus 12v 500VA inverter charger can be used as a UPS supply in a house or office or otherwise in a camper trailer or caravan to power small 240VAC appliances.

With the ability to switch from inverter mode while off grid to a millisecond transfer to 240VAC battery charging when plugged into shore power the Victron Energy Multiplus 12v 500VA Inverter Charger truly is a complete automatic power supply system.

The Victron Energy Multiplus 12v 500VA Inverter Charger is fully programmable and can be set to different battery types including lithium LifePO4, AGM, Gel and Lead Acid batteries.

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 high-speed 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
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 fine-tunes 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
When connected to the internet, systems can be accessed remotely, and settings can be changed.
