The Victron Energy MultiPlus-II 12/3000/120-50 2x120V inverter charger has a feature that many RV, van life, truck, and mobile power users don't fully understand.

However, when shore power is disconnected and the inverter switches to battery power, the system outputs only 120V from AC Output 1. This makes the Victron MultiPlus-II 2x120V an excellent solution for RVs, campers, trucks, boats, emergency backup systems, and mobile power installations that need split-phase pass-through while maintaining reliable battery backup power.

📝 Video Transcript

right here is a Victron Energy MultiPlus 2 12-Volt 3000 VA inverter and this is a standard MultiPlus inverter with some special abilities. First off, as you can see right here, it has two 120-Volt AC transfer switches built into this device. It can AC transfer capacity up to 50 amps and this is a 120-Volt inverter. Why is all of that important and how is that special, okay?

So, as you can see right here, it has a line one, line two, a neutral and a protective earth. It's got actually all of that on all three uh AC in, AC out one, AC out two. AC out one is the one that stays on when you're on battery power only, but if you were to take this to like a place and you plug into a 50-amp receptacle, 50-amp 240-Volt split phase, those lines would feed into here and it would pass through a split phase on AC out one and two. But, when you're on battery power only, it only outputs AC output one and in 120 volts.
