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. Models range from 800VA to 5000VA per module.

Unique PowerAssist feature
The MultiPlus will prevent overload of a limited AC source. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.

Uninterrupted AC power (UPS function) 
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 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. 

Virtually unlimited power thanks to parallel operation
Up to 6 Multis can operate in parallel to achieve higher power output. Three phase or split phase operation is also possible. Please check our datasheets to see which models have paralleling, three phase and split phase capabilities.

Victron Multiplus inverter/chargers must be programmed

Multiplus Inverter/Charger Programming

AM Solar will update the firmware and program the proper settings into your inverter before it is shipped to you.

Add To Cart

To program a Multiplus inverter/charger you will need to have basic PC skills.  A Mac can be made to work, but not consistently.  We do not support Mac programming.  Your PC skills should include the ability to download files and programs, open programs, and connect to devices via a USB port.  You can read the programming instructions here.

Aside from the Multiplus inverter/charger, you will need the following:
• PC Computer (preferably a laptop)
• MK-3 to USB Adapter (Supplied with complete inverter kits)
• UTP RJ45 Cable (Supplied with complete inverter kits)
• DC Power supplied to the unit (This can be supplied by your house battery)
• Internet Connection (For downloading files, the programming can be done offline once the files are downloaded)

If anything above sounded potentially frustrating or completely outside of your abilities, AM Solar can pre-program your inverter for $100.  If you already have your inverter and find that you cannot program it, you can ship it back to us, pay the programming fee, and we will send it back to you, fully programmed.
