Victron inverters have a following among RV, marine, and off-grid builders who value dependable power electronics. The two 3000W Victron models listed here are currently out of stock, so the line is restocking. If you are planning a build, compare other 3000W inverters in our catalog with similar pure sine wave output and matching battery voltage. Check your DC input voltage first, since 12V, 24V, and 48V units are not interchangeable. Reach out by email and we will help you find an equivalent option or let you know when Victron returns.

3000W Victron Inverter Chargers: Choosing Between the 12V MultiPlus-II and the 48V EasySolar-II

A Victron inverter 3000w unit is the heart of a serious RV, boat or cabin electrical system. Unlike a portable power station, it is a hard-wired component: it takes DC from your own battery bank, produces pure sine wave 120V AC, and doubles as a battery charger when shore power or a generator is connected. That combination is why Victron gear shows up in professional van builds and off-grid homes, where the inverter has to hand off between shore, generator and battery without the lights flickering.

This collection holds two Victron units at 3,000W rated output, priced from $1,039 to $1,397. Both are currently sold out; call us to be notified when stock returns or to talk through an alternative. The two are built for different battery voltages and different jobs, so the guide below still applies when you plan a system.

How to choose a 3000W Victron inverter

  • Battery voltage first. The Victron 3000VA MultiPlus-II 2X 120/240V Split Phase is a 12V unit, made for RVs and boats that already run a 12V house bank. The Victron EasySolar-II 3000W 48V Inverter/Charger is a 48V unit for cabins and homes, where the higher voltage keeps cable sizes sane at 3,000W. Pick the inverter that matches the bank you have or plan to build; you cannot change this later.
  • Split phase or single phase. The MultiPlus-II 2x120V handles North American 50A 120/240V split-phase shore connections in one box, which is exactly what a 50A RV pedestal supplies. If your rig has a 50A cord and two 120V legs, this is the model that keeps both legs live.
  • Do you need solar charging built in. The EasySolar-II integrates the inverter, a solar charge controller (MPPT 250/70) and a battery charger in a single enclosure, with the Color Control GX display for monitoring. That saves a separate controller, wiring and mounting space in a cabin build.
  • Efficiency and weight. The EasySolar-II is rated at 95% efficiency. The MultiPlus-II weighs 48 lb, which matters when you are finding wall space in a van.

Setup and usage tips

  • Size the battery bank before the inverter. Use the Solar Kit Calculator with your appliances and ZIP code; it returns inverter watts, battery capacity and panel watts together, and a 3,000W inverter on a small bank will trip on low voltage under load.
  • On a 12V system, 3,000W means roughly 250A of DC current at full output. Budget for heavy cable, a properly rated fuse and short runs between bank and inverter.
  • Set the charger profile for your battery chemistry. Both units charge from shore or generator, and a lithium bank needs a lithium profile to reach full charge safely.
  • With the EasySolar-II, plan the solar array around the MPPT 250/70 controller's input window and keep the panel string voltage within it, including cold-morning voltage rise.
  • Leave the GX display accessible; it is where you will check state of charge and adjust input current limits at a weak campground pedestal.

Frequently asked questions

Which is the right Victron multiplus 3000w inverter for a 50A RV? The MultiPlus-II 2x120V, because it passes through both 120V legs of a 50A split-phase pedestal and runs from a 12V house bank. The 48V EasySolar-II is aimed at stationary installs.

Can I run a 3,000W inverter from a single 12V 100Ah battery? Not at full load for any useful time. A Victron 12V 3000W inverter belongs on a bank of several hundred amp-hours; call us and we will size it with you.

Does the EasySolar-II replace a separate charge controller? Yes. The MPPT 250/70 inside handles the solar array, so a cabin build needs only panels, battery and this one unit plus protection.

When these units return to stock they ship free to the mainland US from our brand partner warehouses, usually within a few business days, with 30-day returns. Call us to reserve one or to discuss a comparable inverter charger for your system.
