Inverter / Charger Multi, pure sine, 800VA / 48V
with internal 9A IUoU Battery Charger and AC Transfer Switch
for Motor home, RC, Camper car, Boat and industrial use
The new style Multi 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.
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.
High start-up power
Needed to start high inrush loads such as power converters for LED lamps, halogen lamps or electric tools.
Uninterrupted AC power
In the event of a grid failure, or shore or generator power being disconnected, the inverter within the Multi is automatically activated and takes over 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.
PowerControl – Dealing with limited generator or shore side power
With a Multi Control Panel a maximum generator or shore current can be set. 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
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.
Digital Multi Control (optional)
The Digital Multi Control panel (DMC) is a remote panel designed to work with all Multis.
The remote control in two different styles you can find here: Digital MultiControl or Digital Multicontrol GX
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.
Virtually unlimited power thanks to parallel operation
Up to 6 Multis can operate in parallel to achieve higher power output. (RJ45-spliter ASS030065510 needed for 500/800/1200VA models)
Threephase capability
In addition to parallel connection, three units of the same model can be configured for three phase output. But that’s not all: up to 6 sets of three units can be parallel connected. (RJ45-spliter ASS030065510 needed for 500/800/1200VA models)
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 major 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.
Configuration by computer or DIP switches
All settings can be changed by means of a computer. Some settings can be changed with DIP switches. For changing settings with the computer, the following is required:
- VEConfigureII software: can be downloaded free of charge at www.victronenergy.com.
- a RJ45 UTP cable and the MK3-USB interface cable is needed.
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...
The Color Control GX you can find here: Color Control GX
The new Venus GX you can find here: Venus GX
