Build Your Perfect Off-Grid Rig With Our System Calculator
Visit CalculatorThe Victron Energy MultiPlus-II 48/3000/35-32 is a high-reliability 48V inverter/charger designed for off-grid homes, marine systems, RVs, and backup power setups. It combines a 3000VA pure sine wave inverter, an adaptive 35A battery charger, and a fast 32A transfer switch in a single unit. When shore or generator power is available, it passes AC through while charging your 48V battery bank. If AC input drops, it automatically switches to inverter power to keep critical loads running. PowerControl and PowerAssist help prevent overload on limited AC sources and support short surge demands smoothly.
3000VA pure sine wave inverter – Delivers clean 230V AC power that’s safe for sensitive electronics and appliances.
High surge performance – Supports demanding startup loads with up to 5500W peak power.
35A adaptive battery charger – Multi-stage charging optimized for 48V battery banks, including lithium.
32A transfer switch – Seamlessly switches between AC input and inverter output.
PowerControl – Limits AC draw to avoid tripping weak shore or generator circuits.
PowerAssist – Adds battery power during short load spikes to prevent overload.
VE.Bus communication – Enables remote monitoring, configuration, and parallel/three-phase expansion.
Programmable relay – Can be set for alarms, generator start/stop, or custom triggers.
Rugged steel enclosure – Built for demanding 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.
