The Victron MultiPlus-II 120V is a multifunction inverter and battery charger with two AC outputs, designed for professional marine, vehicle, and land-based off-grid systems. It supports ESS (Energy Storage System) setups and includes features that help manage limited shore or generator power.
In the event of a grid failure, or when shore or generator power is disconnected, the inverter activates automatically and takes over the supply to connected loads in less than 20 milliseconds. With a GX device, you can monitor and control the system locally or remotely through the VRM app and VRM portal.
Helps prevent generator or shore power overload by automatically reducing battery charging when needed.
Boosts available AC power during peak demand by supplementing limited shore or generator power with battery power.
Fast transfer to inverter operation (less than 20 milliseconds) helps keep many sensitive loads running without interruption.
When paired with a GX device, monitor and control locally (LAN) or remotely using the VRM app and VRM portal.
The unit has two AC outputs. The main output is designed for uninterrupted power and transfers quickly to inverter operation during outages. The second output is intended for loads that should only run when AC input is present.
The inverter takes over in less than 20 milliseconds, which can help keep many sensitive loads running without interruption.
PowerControl helps prevent overload of a limited AC source by automatically reducing battery charging when needed.
PowerAssist can supplement limited shore or generator power with battery power during peak demand, then recharge when demand drops and capacity is available.
Yes, when paired with a Victron GX device, you can monitor and control locally (LAN) or remotely via the VRM app and VRM portal.
Confirm your battery voltage (12V, 24V, or 48V), the inverter size you need (3000VA or 5000VA), and your AC input and transfer switch needs (50A or 95A, depending on model).
Yes, the MultiPlus-II is a key component in Victron ESS setups and supports ESS operation when configured as part of a complete system.
The manual includes important safety and installation guidance, including following applicable electrical codes and qualified practices. If you are not experienced with AC and DC power systems, use a qualified installer.

Orion Van Gear offered the best pricing on my two new MaxxAir MaxxFan Deluxe fans and they arrive SO fast. The install on our our 5th wheel went exceptionally well. Thank you for the great experiences.
The Orion roof rack I got from Orion for my transit mid roof 148 was a piece of cake to install. I was delighted with how easily it went together! My older son was unable to help that day but even so I got it done in about 4.5 hours. The Instructions are clear, the materials are all clearly labeled. There was no grinding, or tweaking of any kind needed! Can’t wait to get the roof panels!
Pictures look great!
22 day delivery time. I guess it happens often with USPS going thru L.A. Update. Issues with this order and delivery have been resolved. Thanks for the quick response.
I mounted the lights and I was very pleased.
Purchased a Stealth+ Roof Rack for my Ram Promaster Low Roof (one of the few options available for the Low Roof Promaster) along with a few other items. We are very pleased with the engineering, fitment and appearance of the rack. We hit a couple of install bumps along the way but were blown away by the rapid response of the Orion Team anytime we reached out to them. We will definitely be working with them again as our van build progresses.
