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.

Key Features

  • Pure sine wave inverter with 4 kW continuous output and 7 kW peak power
  • Powerful 55 A adaptive battery charger for rapid recharging
  • PowerControl and PowerAssist prevent AC input overload and supplement limited sources

My puppy went right to sleep
Color: Neutral
With having a new baby puppy sometimes they can have anxiety leaving their mother and siblings behind. This helped my puppy so much with the transition from being with them to being by himself. This cute adorable plush puppy has a quiet heartbeat that soothes my puppy to sleep. It is well made and serves the purpose it was intended for. I also loved that this came with teething toys that my puppy loves to chew on and the blanket is super soft.

Helped our puppy settle in from the first night!
Color: Blue
We got this kit to welcome our 8 week old puppy. The warming packs work really well. Especially important since it was our puppy’s first time separated from him mom and littermates. The heartbeat is loud enough for us to hear at night but we got used to it. The Snuggle Puppy stays in his crate as his special companion and he snuggles like it’s one of his pack. Ahead of puppy’s arrival, we put one of my husband’s tshirts on the Snuggle Puppy to add his scent to it. I think that helped the transition, too. Luckily, this puppy doesn’t destroy stuffed animals. After 3 weeks all but the tongue are in tact. I’m not sure how long it would last if he was a destroyer. The toys are ok. The freezable teething heart is a hit. He has settled in to his nightly routine really well and gets excited to greet his pal!

Perfect puppy starter kit and gift! Perfect for plane rides and kennel!
Color: Neutral, Color: Neutral
Perfect puppy gift! We use the kennel as her safe haven, and for potty training . This heartbeat tool is amazing and helped our puppy get acclimated to her kennel. She goes into her kennel and sleeps with it on her own. It calmed her down on the plane completely. We had a 6-hour flight and she did fine with the heartbeat toy. At home innthe kennel, the whining was very very minimal the first couple days, then it stopped. As you would hear and see her snuggle up and fall asleep. I think it is a bit pricy, but not too bad for the benefit. The heartbeat is seperate and is putninside a pouch on the stuffed animal. The blanket is soft, beautiful and perfect size. Good quality fabric. Both chew toys were loved by her.I do notice my large breed puppy prefers the rope and small tennis ball type chew toys. However, she plays with these too. Haven't used the heating packs yet, they go inside the pouch with the heartbeat item. I am sure we will because my puppy does love to be in front of my small heater under my desk to keep my feet warm. The packaging was extremely nice and fancy and was complimentary to the items inside.

Best Idea for Puppy's First Day Home
Color: Pink
I was a bit reserved on purchasing this kit because it was a bit expensive. After a month now with my pup at home, this was the best investment for us and our GSD. On the first night, we used the heart beating snuggle puppy and blanket. She slept the entire night without an accident or a cry. The heartbeat in the snuggle puppy and the heat pad was the best idea. Our puppy never felt alone (just fyi, her crate was in the room with us for the 2 weeks). A month later, she is so protective of her snuggle puppy. We only used 1 heat pack to soothe her during the first week. The heat packs last a while. Our GSD now uses the snuggle puppy as a pillow or an object to be close to while she is in her crate. Any new puppy owner could definitely benefit from using this. Of course, with all things puppy, it does require a bit of time to correlate toys as a positive thing. We exclusively keep the snuggle puppy in her crate and make it a part of her secure place. My GSD puppy did really care for the teething heart toy. Even after freezing it, she didn't care for it. She also outgrew the small toy. She will chew it from time to time but it doesn't entertain her much. I found the kit, overall, very helpful with our puppy's adjustment to our home. She sleeps through the night since 8 weeks old and now at 12 weeks old. We've never had an accident in her crate overnight with the help with the snuggle puppy.

Amazing kit for your puppy
Color: Blue
We’ve had 6 puppies over the years, and this is the first time we’ve had this wonderful little kit to welcome our little one home. We had the blanket with his litter so it smelled like them when he came home. He he loves that blanket, he loves the dog with the little heartbeat, and the teething toys. The 5 star review is because everything in this kit is so well made, really wonderful quality, and a great value. The blanket is a very nice thick plush, not some cheap one. The stuffed dog is big and fluffy and well made, the heartbeat works wonderfully, and the little chew toys safe and well made.i would encourage anyone who’s bringing home. A little one please get this first. It’s going to make your pup more comfortable when they get home, and will help then sleep better during the night and their naps. Very Well Done !
