Quattro-II - 12/3000 - 120-50/50 - 2X 120V

Similar to the MultiPlus-II 2x120V, the Quattro-II 2x120V is a combined inverter and charger specifically designed for standard North American 50A 120/240VAC split-phase applications. Additionally, it can accept two AC inputs and automatically connect to the active source.

120/240V Input and Output, or 120V Input and Output (Always 120V Output When in Inverter Mode)

The two AC inputs can be supplied from a split-phase 120/240V source or a single-phase 120V source. When one of the AC sources is available, the Quattro will feed through the AC to its output. The output will therefore mirror the AC input.

The inverter/charger connects to the neutral and the preferred input line (L1). The power needed to charge the batteries will therefore be drawn from L1.

The Quattro switches to inverter operation when no AC source is available. The inverter output is 120V single-phase. In invert mode, the Quattro connects both output lines (L1 and L2) together to provide 120VAC to loads on either line.

Any 240V loads will therefore be supplied only when the Quattro is supplied by a split-phase AC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery.

PowerControl and PowerAssist - Boosting the Capacity of the Grid or a Generator

A maximum grid or generator current can be set. The Quattro will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function).

PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is often required only for a limited period, the Quattro will compensate for insufficient generator, shore, or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery (available on L1 input only).

Two AC Inputs and Two AC Outputs

The Quattro can be connected to two independent AC sources, for example,shore-side power and a generator, or two generators. The Quattro-II will automatically connect to the active source.

The main output has no-break functionality. The Quattro takes over the supply to the connected 120V loads in the event of a grid failure or when shore/generator power is disconnected. The transfer time of the L1 output is less than 18 milliseconds, so computers and other electronic equipment will continue to operate without disruption. The transfer time of the L2 output is longer: approximately 40 milliseconds.

The second (auxiliary) output is live only when AC is available on the input of the Quattro. Loads that should not discharge the battery can be connected to this output.

Virtually Unlimited Power Thanks to Parallel and Three-Phase Operation

Up to 6 Quattros can operate in parallel to achieve a higher power output. In addition to parallel connections, three units of the same model can be configured for three-phase output. In multi-phase setups, L2 is disabled on all units.

On-Site System Configuring, Monitoring and Control

Settings can be changed in a matter of minutes with the VictronConnect app or VEConfigure software (computer or laptop and MK3-USB interface are needed). Several monitoring and control options are available: Cerbo GX, Color Control GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, and Digital Multi Control Panel.

Remote Configuration and Monitoring

Install a Cerbo GX or other GX product to connect to the internet. Operational data can be stored and displayed on our VRM (Victron Remote Management) website free of charge. When connected to the internet, systems can be accessed remotely, and settings can be changed.

NON FICTION IS A GREAT WAY TO LISTEN WHILE YOU DRIVE! TRY AUDIBLE!
Format: Audiobook
LET THEM AUDIBLE NON-FICTION INSPIRATIONAL BOOK ON LISTENING TO MEL ROBBINS MOTIVATIONAL ADVICE MAKES MY DRIVING DESTINATIONS ENJOYABLE! I had something like 24 AUDIBLE CREDITS that have built up because I'm a visual person that loves to read. I've had the membership for over ten years and I only like certain NON FICTION SELF DEVELOPMENT books which I listen to Memoirs, Self help, but never fiction books, because my imagination is more vivid when I read. I always either listen to my podcasts on Spotify or NON-FICTION on AUDIBLE which is owned by Amazon. I can't drive anywhere without my Podcasts or very few Non-Fiction Titles that interest me, but I have had those credits and I love MEL ROBBINS so I decided to try it on AUDIBLE. My friends who read that listen to fiction on AUDIO understood why I bought the same fictional title and I had already loved reading it on my Kindle. It was a favorite lifetime reading experience and I own many of the same KINDLE & AUDIBLE versions but I noticed that fiction book that it was one of the most beautifully written books that when I went to listen to it, I quickly gave up because it was bland. I have been told by more frequent readers like myself who listen to the Audio version and recommend it to me on Audio since they enjoyed it better have said listening to fiction is a skill that you have to develop, so I stick to NON FICTION and I need to listen to something while I'm driving so I buy the Kindle Version & the AUDIBLE and it makes my driving to destinations shorter.v That's why I have Spotify because there's two favorite podcasts but I pay extra for no commercials and now my top favorite podcast has commercials which I 'm considering cancelling because the reason I pay extra is because the commercials drive me crazy so now Spotify says it's up to the podcast. The reason I've been a member since 2018, is because it is synced to the Bluetooth, in my car and the podcasts don't require Cell towers so you don't get the buffering that I do with Audible in areas where there aren't Cell towers which we call them dead zones. I'm recommending this AUDIBLE PURCHASE called, "LET THEM," because MEL ROBBINS is a new motivational author to me, and she wrote the book which she has some fascinating inspirational content, that I have learned some ideas to improve my life. She is a fantastic narrator in her soothing voice. One nice thing about AUDIBLE is they are extremely friendly and if you don't like the AUDIO BOOK Listening experience, you can return it, which you can't do with the KINDLE Books. so I have had to return something only twice in fifteen years, since I usually love what I purchase. I do recommend this book on AUDIBLE to listen to or if you don't have a membership they used to have a free trial and a free book if you're a new member. But I'm not sure, but however medium you choose this is a FAVORITE and it's a bestseller that I can promise you will love it, as well. It has a very high rating of tens of thousands of five star ratings which is even more evident that it's a Spectacular choice!

Let Them and Let Me, is what I needed!
Format: Hardcover
I wish that I could give this book much more than 5 stars. I absolutely loved reading it. The book is so interesting and the information is useful and makes a lot of sense. I have been reading the book since I received it on March 5, 2026 and it was very hard for me to put it down. I am now on the concluding chapter "Your Let Me Era Is Here." I feel a little sad that I am finishing the book because I want to know more. However, I decided to practice the suggestions and theories the author stated in the book to see if they really worked. The 5-4-3-2-1 suggestion was used anytime there was something that I didn't feel motivated to do, and it worked. I felt better afterwards. The "Let Them" and "Let Me" theories have worked also. But, I realized it is going to take time for me to make the needed changes consistently. Still, I am very happy that I purchased and read this book. It is definitely worth the money and time spent reading and making application of the information. It boosted my confidence!

I say read it then write your own review
Format: Hardcover
I enjoyed the read. " Let them " it's seems so easy. You do you " me" and let them do them. Easy. I felt as an adult most of us already have adjusted passed the emotional baggage of others. Not 100 because no one can say they never get caught on a snag time to time. Especially driving in traffic or standing in line behind adult kindergartners but for the most part you just let it go before it causes any reflux. The book does lay it out and simplifies it by using her life experiences while adding contexts of professionals outlooks and numbers. I gave it a four out of five because I kept reading it while always thinking I get it but it's a person to person awareness. I will always have to be the bigger person and except that the problem may be them but I'm going to let them be the problem but I will just adjust my way and let them continue to be the unconscious fool they are or until they see for themselves how unruly and trivial they truly are. I think personally it's like wearing a mask. For it to actually work everyone needs to wear it. Best thing about this book was the title itself. "Let them " because when you realize you can't control anyone other than yourself you can mentally process that it's okay for you to just be yourself and forget about the rest. Nothing changes if nothing is changed.

Loving it so far
Format: Paperback, Format: Paperback
I really didn't know what to expect with a book full of names, but I love a murder mystery & needed more post work hobbies, so I thought this would be interesting & was I right. This book has been so engaging and keeps my mind in a good focused place instead of the usual dissociation after a stressful day of work or doom scrolling. It was nice to come up with my own little system as to how I would solve the clues on each page & keep track of everything. If you're interested in puzzles, or just need something interesting to keep busy, I feel this is a great concept to solve a mystery. 100% would recommend.
