The Victron Energy Multiplus II Inverter Charger – 12V 3000VA/120A (32)from Victron Energy is a multifunctional inverter/charger with all the features of the Multiplus, but it also has an external current sensor option which extends the PowerControl & PowerAssist functions and optimises self-consumption. It is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single compact unit. This design not only saves space, but simplifies your installation.
The Multiplus-II is ideal for professional marine, yachting, vehicle and land-based off-grid applications, has a built-in anti-islanding function and a long list of country approvals for use in Energy Storage System (ESS) applications. It can be used in off-grid as well as grid-connected PV and other alternative energy systems, and is compatible with both solar charge controllers and grid-tie inverters.
The built-in AC transfer switch performs the function of an Uninterruptible Power Supply (UPS) on the main AC output. In the event of a grid failure, or shore or generator power being disconnected, the inverter is automatically activated and takes over AC supply to the connected loads. This happens in less then 20 milliseconds and ensures that sensitive connected equipment continues to run without disruption. This feature can be deactivated if not required. The second/auxiliary output is live only when AC is available on the input of the Multiplus-II and is intended for connection to heavy consumption loads (e.g. water heater) that would quickly discharge the battery if run from the inverter.
You can achieve virtually unlimited power thanks to the Multiplus-II’s ability to be parallel connected and setup for 3-phase operation. It can also be remotely monitored and controlled via a multi-functional GX device such as the Cerbo GX. It can also be controlled and configured over Bluetooth through the Victron Connect App using a VE.Bus Smart Dongle.
Please note: Cables are not supplied. For the DC (battery) connection, Victron recommend 2 x 50mm² cables protected with a 400A mega fuse. The 230V output is designed to be hard-wired to sockets or other parts of an AC system.

Gareth Mckee2025-05-26Trustindex verifies that the original source of the review is Google. So I had a lot of back and forth chat with Glen. He is very knowledgeable and interesting guy if you're into batteries. So I left my review a good while to test the battery. I bought the 175AH arcticxtreme V2. This fits into a standard (low profile) caravan locker. I actually get 182AH from it. So it's more than rated. I upgraded my solar to victron 175w and mppt. Then I upgraded my BCA charger from apuljack to lithium profile. Quote expensive really. But we have a coachman xcel and did suffer with AGM not lasting at all. Using the battery app I can see our movers pull 100 amps at times. No idea how the wires don't melt actually. Then the leveling. No wonder AGM batteries are not so good. Since moving to this I have never been near flat. Even running a coolbox fridge and no hook up for 4 days. No problem. The solar with this battery smash it easily. I would always use these batteries. I don't think you can match the case size Vs power output. Really solid product even in winter. Luke Poucher2025-04-10Trustindex verifies that the original source of the review is Google. Purchased a battery from lithium pro 6 months ago and was the best investment for my motorhome. Even with the 105ah it gives plenty of power and paired up with a 2000w inverter it turned the van into a hassle free wild camping van. The customer service again was by fair the best, glen at lithium pro has always been a message away if needed. I am that happy with the product I have just recently bought a 280 seat base for my van to help with more extreme wild camping in cold temps. I have looked at other manufacturers including the big names you see and I can say there nothin compared to the quality lithium pro provides Safer Sussex2025-04-09Trustindex verifies that the original source of the review is Google. This is a fantastic bit of kit, durable, long life batteries and comes with first class, rock solid support. Would highly recommend Lithium Pro Energy batteries. William Lee2025-03-18Trustindex verifies that the original source of the review is Google. Had 105 lithium system fitted to my new bailey adamo 75-4i. System brilliant but bailey need to pull there finger out so it can be monitored on the moho panel. Thankfully there is a very impressive app that tells you all you need, including incoming voltage be it solar panel or mains hook up as well as draw off. After care is excellent slight issue sorted in minutes. Think I purchased the right system Amanda Leese2025-01-21Trustindex verifies that the original source of the review is Google. This battery has changed my camping experience. I invested at the beginning of last spring. I wish I took the plunge years ago. I don’t have to think about whether I have enough juice so keep my fridge and lights going anymore. I can charge my gadgets, loads of lights on, fridge on with ice compartment. No more hooking up, I get more choice where I pitch up too. The app is brilliant. In the beginning I had a few questions , I just WhatsApp lithium pro and they text back instantly, even at weekends. The service if excellent. I’ve booked on more green camping sites now. I’m so thrilled with the over all experience and service. Well worth the money. Many thanks lithium pro Nathan Soles2025-01-10Trustindex verifies that the original source of the review is Google. Excellent costumer service, very responsive to any questions on WhatsApp, even at weekends. Super important to me, as I installed over the weekend before a big trip, all season, in Winter! Unsolicited follow ups to how I was doing 3 weeks later also, Which was very nice! The 460ah Enduravolt battery has performed flawlessly so far, in winter ski resort conditions. It has integrated very well and charges fast with Victron solar, AC/DC and DC/DC chargers. Also, has the required protections to change off any charger I'm informed. Glynn Biss2024-12-14Trustindex verifies that the original source of the review is Google. I couldn’t be more happy with my Lithium Pro leisure battery (175AH Arctic Xtreme). The battery is of the highest quality and I love the App which allows me to monitor the performance of my battery via my mobile phone. We are now able to be off grid in our camper van for extended periods. David joynes2024-10-31Trustindex verifies that the original source of the review is Google. I needed technical help and called their office. An employee listened to my problem and was able to quickly and efficiently resolve the problem. They were very helpful. Jonathan Miles2024-10-06Trustindex verifies that the original source of the review is Google. Great guys, brilliant product and more importantly they took the time to explain everything to a nervous buyer. Battery works lika a dream and the Bluetooth interface is superb. Did I also say I bought it at a show and they even carried back to my van, thanks guys. Jimmy Michael2024-09-28Trustindex verifies that the original source of the review is Google.
