Victron MultiPlus-II 48V Inverter/Charger with PowerAssist and ESS Integration

Professional-Grade Inverter/Charger for Demanding Off-Grid and Backup Power Systems

The Victron MultiPlus-II is a high-performance multifunctional inverter/charger designed for demanding marine, mobile, and off-grid applications. Combining a robust 230V pure sine wave inverter with a powerful adaptive battery charger, this unit features Energy Storage System (ESS) capabilities, allowing seamless integration with solar, grid-tied, and generator systems for intelligent energy management. Delivering continuous output of 4 kW and peak power of 7 kW, it ensures reliable operation for critical loads even during high-demand periods. The integrated 55 A charger rapidly replenishes your battery bank, minimising generator run time and maximising solar utilisation.

PowerControl & PowerAssist – Intelligent Energy Management

The MultiPlus-II’s PowerControl feature allows precise limitation of AC input current, preventing overload on generators or the grid. PowerAssist extends this functionality by supplementing limited grid or generator power with stored battery energy during peak loads, then recharging the battery once demand decreases. This maximises system efficiency and guarantees uninterrupted power to essential loads, making it ideal for sites with limited shore power or generator capacity.

Seamless AC Supply & Dual Output Functionality

The main AC output delivers uninterrupted power during grid or generator outages, with transfer times under 20 milliseconds, keeping sensitive electronics operational. The secondary AC output is live only when input power is present, ideal for non-critical loads such as water heaters. Both outputs integrate with PowerControl and PowerAssist for smart load management, ensuring critical loads always have priority.

Scalable & Flexible System Configuration

Up to six MultiPlus-II units can be connected in parallel for expanded power capacity. Three units of the same model can be configured for three-phase output, and up to six sets of three units can operate in parallel for very large installations. On-site configuration is simple via VEConfigure software, while real-time monitoring is available through Cerbo GX, Ekrano GX, Digital Multi Control Panel, VictronConnect, or the VRM Online portal.

High Efficiency & Robust Design

With a maximum efficiency of 95%, the MultiPlus-II minimises energy losses while delivering reliable AC power. Its rugged IP21-rated steel enclosure and fan-assisted cooling allow safe operation in temperatures from -40°C to +65°C. Compatible with lithium, lead-acid, and zinc-bromine batteries, it provides flexibility for diverse energy storage systems. The internal transfer switch is rated at 32 A, ensuring safe passage of grid or generator power.

Movie lighting must have.
Size: 11.8FT for 55''-65'' TV, Size: 11.8FT for 55''-65'' TV
This is exactly what it was in the listing. It was very easy to install they stick to the back of the tv very well. The lights strip is good quality and they wont fall off the tv even from the heat.. The app is easy to use. Will say there are a lot of options to control it from the app. Once the control box is behind the tv your not going to be reaching back there to turn it off and on. I have mine connected to Alexa and Google so i can control them with my voice. They look great for watching movies even in a somewhat lit room. Be mindful of the camera on the top of the tv I did have to calibrate it 7 times cause it wasn't picking up all the corners and i accidentally hit the camera while walking around if your tv is on the wall you have nothing to worry about unless you have my first issue of it not catching the corners properly. The little orange squares don't stick too well especially since i had to do this several times. Even tried it without the squares and still had problems. The video was recorded after the second time of calibrating it. The problem comes when you try to get the hue right. Everything white makes the lights turn red so i had to mess with the saturation and the white balance on color calibration feature on the app to get it as close as possible to the white on the tv and its still something i have to adjust ever time i watch something.(Shown in the second picture)

Amazing!
Size: 11.8FT for 55''-65'' TV
I absolutely love these lights. I will never go back to no lights again haha. Perfect for movies, shows, video games. Also super easy to get it installed. The only issue we ran into a little bit was the app and trying to get the tv shape and layout registered.

Effective & Attractive with Wireless Charging
Color: Blue, Color: Blue
This "valet" organizer, which is the first time I've heard that term for a product like this, is nearly perfect. For me, it checks all of the boxes and in a perfect world, I would have opted for a smaller piece with only three compartments for mobile, wallet, and keys. It's well made and quite attractive, especially the blue (favorite color, so I'm biased). The only feature I'm not a fan of is how the removeable, wireless charging pad was implemented, which sits up on a small lip at a slight incline. However, I'm not complaining one bit as the wireless charging is great, and it's a differentiator that determines the value of the piece. I would have preferred the pad be built into the piece, however the angle of it does make it easy to grab opposed to using your finger(s) to pry it up.
