Build Your Perfect Off-Grid Rig With Our System Calculator
Visit CalculatorThe Victron Energy MultiPlus-II 24/3000/70-32 is a robust all-in-one inverter/charger for larger 24V off-grid, RV, marine, and backup power systems. It combines a 3000VA pure sine wave inverter, a 70A adaptive multi-stage battery charger, and a fast 32A transfer switch in one unit. When shore or generator power is available, it passes AC through while charging your battery bank. When AC drops out, it switches to inverter power smoothly to keep your loads running. PowerControl and PowerAssist help protect limited AC sources from overload while supporting short high-surge demands.
3000VA pure sine wave inverter – Clean 230V AC output that’s safe for sensitive electronics and appliances.
High surge capability – Handles demanding startup loads with up to 5500W peak power.
70A adaptive battery charger – Multi-stage charging designed for medium-to-large 24V battery banks.
32A automatic transfer switch – Seamless switching between shore/generator input and inverter output.
PowerControl – Automatically limits charger draw to prevent tripping weak AC sources.
PowerAssist – Adds battery power during short load spikes to support heavier demands.
VE.Bus communication – Supports Victron monitoring, configuration, and system integration.
Programmable relay – Allows custom alarms or generator start/stop automation.
Auxiliary AC output – Helps manage critical vs. non-critical loads cleanly.
Rugged steel enclosure – Durable casing suitable for mobile and stationary installs.

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.
Ray B.
I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!
Roger V.
I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
