Build Your Perfect Off-Grid Rig With Our System Calculator
Visit CalculatorThe Victron Energy MultiPlus 12/800/35-16 is a compact inverter/charger designed for reliable off-grid, marine, RV, and backup power systems. It combines a pure sine wave inverter with a built-in battery charger and an automatic transfer switch, so you can power AC loads from your battery bank and seamlessly pass through shore or generator power when available. With PowerAssist and PowerControl, it helps manage limited AC sources while still supporting short peak loads, making it a dependable all-in-one heart for smaller 12V systems.
Pure sine wave inverter output – Clean, stable AC power that’s safe for sensitive electronics and appliances.
800VA continuous inverter capacity – Ideal for smaller systems needing dependable everyday AC power.
PowerAssist support – Adds battery power to supplement weak shore or generator input during brief load spikes.
PowerControl management – Prevents overload by automatically limiting charger draw when AC loads rise.
Automatic transfer switch – Built-in 16A transfer switch provides fast, seamless switching between inverter and AC input.
Multi-stage battery charging – Integrated charger delivers proper bulk/absorption/float charging for healthier batteries.
VE.Bus connectivity – Enables system monitoring and configuration through Victron tools and compatible GX devices.
Low-idle energy modes – AES and Search modes reduce power use when loads are light.

Can the MultiPlus automatically switch between shore power and battery power?
Yes. The built-in 16A transfer switch automatically passes through incoming AC when available and switches back to inverter power when AC input is lost.
How much charging power does this unit provide for my 12V battery bank?
It includes a multi-stage charger that delivers up to 35A to the house battery, helping recharge efficiently and extend battery health.
Will this work with a small solar/off-grid setup?
Absolutely. It’s a great fit for compact 12V systems like small cabins, RVs, or boats where you need reliable inverter power plus charging in one unit.
Can I expand or monitor this later with other Victron gear?
Yes. Through VE.Bus, it can connect to Victron monitoring/control devices (like GX systems) and supports future system upgrades.

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.
