This inverter charger powers 2 AC output circuits from a 50 amp input and helps prevent overload during demand spikes. It delivers 2,400 watts of continuous output, 120-amp battery charging, and under 20 ms transfer for sensitive electronics.
When a microwave or coffee maker pushes limited shore power too hard, this unit steps in with PowerControl and PowerAssist to help prevent overload and support peak demand using battery energy. It pairs that load support with a 50 amp AC input and 2,400 watts of continuous output power at 77ºF with 5,500 watts of peak power. In real use, that gives you more room to run household-style loads when incoming AC power is the bottleneck.
This unit uses a single AC input and 2 AC outputs, making it easier to separate how power is distributed through the coach. With a single-phase 120V source, the L1 input accepts incoming power for charging and passthrough while the unit supplies 120V on both output lines. That gives you more flexibility when feeding multiple branch circuits from one inverter/charger.
Short power interruptions can reset a residential refrigerator or knock sensitive electronics offline right when shore power drops. This inverter switches to inverter operation in under 20 milliseconds with UPS functionality, and it provides 120VAC to loads on either output during inverter operation. The practical payoff is that connected loads stay powered through the switchover instead of going dark during the handoff.
Instead of feeding everything through a single AC output, this unit provides 2 AC outputs so you can distribute power to multiple circuits more cleanly. In inverter mode, the unit internally connects L1 and L2 together to provide 120VAC to loads on either output. That helps support both sides of a distribution panel with 120V power when no AC source is available.
Some inverter chargers top out as a one-box solution, which becomes a limitation once the system grows or power demands change. This unit supports parallel and 3-phase operation, and it also supports ESS plus remote monitoring and control when paired with a GX device (sold separately) through the VRM portal. That gives you a platform that can start as a single 12V inverter charger and expand into a larger monitored power system without replacing the core unit.

Hi, everyone. Steve here with etrailer. Let's take a real quick look together at the Victron MultiPlus-II. It's a powerful 3000 watt inverter and battery charger that's designed for 12 volt systems. Now, this all-in-one system unit, it will combine a true sine wave inverter with a smart battery charger, giving you clean, reliable AC power when you're off-grid, and it gives you efficient charging when shore power or a generator is available. And you've got your on off switch over here.
And you got some different rubber parts here and stuff that you can either take off or use as needed. One standout feature is the dual AC setups. That's gonna allow you to power essential loads while also managing charging and other circuits at the same time. It gives you a strong surge capability and it can handle demanding appliances that give you startup loads with ease. Now as you can see here on the front, you have the charger inverter and different light up options here that are gonna give you the display outputs that you need.
When this is connected to an external AC source, the MultiPlus-II two uses Virons power assist feature to prevent overloads by supplementing power from the batteries when needed. And if that AC source we inchesre to drop out, it'll then automatically switch over to inverter mode in less than a millisecond, providing UPS level backup power for sensitive electronics. And of course, you got the panel here. And then you've got another thermal sensor here as well. So if you want to, you compare this with the Victron GX device, giving you full system monitoring and remote access through the Victron VRM portal.
Now let's go over some quick dimensions real quick before we wrap it up. Overall, I get about 10 and seven eighths inches wide overall. As far as our height, about five and 13 16ths. And then if you we inchesre looking at it from the side like this, and we're going for the longest part, which is at the bottom, I got about 22 and 13 16ths inches long. Now, more likely than not, whenever this is set up, it will be inverted, meaning it's gonna be standing up more like this when it's installed.
And there is a lot of weight to this, so be careful. Make sure you're checking the instructions. Get it installed by a qualified technician. You can reach out to us here at etrailer. We have some installers that we're related with and everything. You can use our dealer locator tool and we can get you in touch with them for your setup and a personalized installation if you need assistance. Folks, that's gonna wrap up our quickly together. I'm Steven. Thanks for watching.

Installed and working. Used your video to make certain my hook up went smoothly.
This is an excellent product being a mobile rv repair buisness I have installed many. E Trailer was very fast with delivery and will continue to get my business.
It was easy to install, except for the 120 wire connections. That took a lot of work. Look for YouTube videos on how to release the spring clasp on the 120 v connectors. It works great in our 5th wheel and supplies power to both sides of the 50 amp. I don't have to worry about which leg of 50 amp I have power on from the batteries.
Condition: Badly Dinged
Notes: Item has a minor cosmetic ding on one corner.
