When switching between shore power and a generator gets messy, this unit connects both directly with dual AC inputs. PowerAssist fills in during load spikes, so appliances keep running without extra transfer hardware or breaker trips.
When a microwave or coffee maker pushes a 30 amp hookup or small generator too hard, this unit steps in with PowerControl and PowerAssist to prevent generator or grid overload and boost AC power during 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 real household loads when incoming AC power is the bottleneck.
Managing separate shore and generator inputs often requires external switching hardware and extra wiring that complicates installs. This unit includes two AC inputs, so both sources can be connected directly without adding separate transfer equipment. In practice, that simplifies system layout and reduces the need for additional components when working with multiple AC sources.
Short power interruptions can reset a residential refrigerator or knock sensitive electronics offline right when shore power or generator input drops. This inverter switches to inverter operation in under 20 milliseconds with UPS functionality, and its main AC output includes no-break functionality that maintains power to connected loads during grid or generator outages. The practical payoff is that selected loads stay powered through the switchover instead of going dark during the handoff.
Running every circuit through the inverter can drain batteries faster than expected when AC input is lost. This unit uses a main AC output with no-break functionality and a secondary AC output that is live only when AC input is available to prevent unnecessary battery discharge. In real setups, that keeps non-essential loads from pulling from the battery when shore or generator power is not present.
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, split-phase, 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.
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.
