If you're diving into off-grid RV living, one of the most important decisions you'll make is choosing the right inverter. Whether you're setting up your very first solar system or upgrading your current rig, understanding the difference between the Victron Multiplus and the Multiplus II is crucial for building a reliable and efficient off-grid setup.
In our latest episode of Todd’s Two-Minute Tech Tip Tuesday, brought to you by Big Beard Battery, Todd breaks down what you really need to know when choosing between these two inverters—and how to match your choice with the kind of RV you have.
✅ Know Your Rig: 30-Amp vs 50-Amp
If you have a 30-amp RV, you’re in luck. Both the original Multiplus (the cube) and the Multiplus II (2x120) will work. Your choice mostly comes down to available space and form factor.
For 50-amp RVs, your best bet is either running two inverters—or going with a Multiplus II 2x120, which can cover both hot legs with a single unit.
🔌 What’s the Difference Between Multiplus and Multiplus II?
Multiplus (Cube): Single leg output. Great for 30-amp RVs. Compact and straightforward.
Multiplus II (2x120): Dual leg capability. Ideal for 50-amp systems where you want to run more than just the basics.
🛠️ Installation Tips
Whichever you choose, consider rewiring your system so the inverter feeds directly into the main panel—not just a sub-panel. This gives you the ability to run anything in your RV (though not everything at once).
A single Multiplus II unit gives you about 2,400 watts, which is enough to power one air conditioner and a refrigerator.
⚡ Final Thoughts
If you're new to solar or just getting started with RV tech, it can be overwhelming. But your inverter choice doesn’t have to be. Todd breaks it down in simple terms to help you make the right decision based on your setup, budget, and power needs.
