Victron Energy MultiPlus-II 24/3000/70-50 120V UL (PMP242305102): a pure sine wave inverter, battery charger and automatic transfer switch built for modern solar and lithium systems. Run 120V AC loads from your 24V battery bank with 3000 VA / 2400 W of continuous pure sine wave power and 5500 W peak. When shore power, a generator or the grid is connected, the 70 A charger refills your batteries and the 50 A transfer switch takes over in less than 20 ms. PowerControl, PowerAssist, ESS support and a built-in ground relay make it a favorite for RV, marine, off-grid and home backup systems. Backed by Victron's 5-year limited warranty.

⚑ Is It Right for Your System?

Built for 24V battery banks powering standard 120V 60 Hz North American AC loads. Common uses:

  • RVs & campers
  • Boats & yachts
  • Off-grid cabins & solar
  • Home backup & ESS
  • Work trucks & vans
πŸ“ Quick check before you order:
  • Your battery bank is 24V (inverter input range 19–33 V).
  • You need 120V single-phase output. Need 240V? Stack two units for 120/240V split phase, or look at the 2x120V models in the table below.
  • Your AC loads stay within 2400 W continuous at 25Β°C, with short surges up to 5500 W.
  • Your shore, generator or grid input is up to 50 A. PowerControl lets you set a lower limit.
  • Plan for battery cables, a DC fuse and AC wiring sized per Victron's manual (not included).
  • Need UL? This model carries UL 458.

Why Choose a Victron MultiPlus-II

πŸ”

Three Units in One

A pure sine wave inverter, an adaptive battery charger and an automatic transfer switch share one box, saving space and wiring.

πŸ”Œ

PowerControl & PowerAssist

Set a maximum shore or generator current. When loads spike past it, the MultiPlus-II adds battery power so the breaker doesn't trip.

β˜€οΈ

Built for Solar & ESS

Supports Victron's Energy Storage System (ESS) mode for self-consumption, and works with Victron GX devices, MPPT solar chargers and lithium battery BMS integration.

⚑

Fast, Smooth Transfer

Switches to battery power in less than 20 ms. A built-in ground relay connects neutral to chassis automatically when running on batteries.

πŸ”—

Expandable

Up to 6 units in parallel, and 3 units for three-phase output. Two units can be stacked for 120/240V split phase.

πŸ›‘οΈ

5-Year Victron Warranty

Victron covers the MultiPlus-II for 5 years from purchase by the original end user, and warranty claims go through us.

πŸ”Œ

Shore, Generator or Grid

Charges from 120V shore, generator or grid power, and PowerControl keeps it within your shore or generator limit.

🚀

Starter Battery Output

A separate 4 A output keeps an engine or starter battery charged.

🌑️

Temperature Compensation

A battery temperature sensor input adjusts charging for hot and cold conditions.

❓ Common Questions

What's the difference between the MultiPlus-II and the original MultiPlus?
The MultiPlus-II adds ESS (Energy Storage System) support, a built-in ground relay, an option for an external AC current sensor and tighter integration with Victron GX devices, which is why it's the usual choice for solar, lithium and home backup systems.
Will it start my air conditioner, microwave or pump?
Motors and compressors pull a short surge when they start. This model handles surges up to 5500 W, with 2400 W continuous. Send us the appliance labels and we'll confirm.
Will it work on smaller shore power or a small generator?
Yes. PowerControl lets you set the maximum AC input current (up to 50 A), and PowerAssist adds battery power during peaks so a small shore connection or generator doesn't trip.
Can I get 240V from it?
One unit gives 120V single phase. Two identical units can be configured for 120/240V split phase, or choose a 2x120V model if you have split-phase shore or generator power.
Can I use it with lithium batteries?
Yes. Charge voltages are adjustable, and with a GX device the MultiPlus-II can take charge commands directly from a compatible lithium battery's BMS over Victron's communication ports.
How do I program and monitor it?
Use an MK3-USB interface with Victron's free VEConfigure software, or a VE.Bus Smart dongle with the VictronConnect app. A GX device like the Cerbo GX adds ESS control and remote monitoring on Victron's VRM portal. All are sold separately.
Is it UL listed?
Yes, this model carries UL 458. Victron notes that the ESS grid feed-in function isn't UL 1741 or CSA certified, so check with your utility before exporting power.
What size cables and fuse do I need?
Victron's manual lists the recommended battery cable size and DC fuse for this model. Ask us and we'll spec your wiring.
How does the warranty work?
Victron covers it for 5 years from the original end user's purchase date. Warranty claims go through the place of purchase, so contact us and we'll handle it with Victron.
