Victron Energy MultiPlus Compact 12/2000/80-50 120V (CMP122200102): a pure sine wave inverter, battery charger and automatic transfer switch in one unit. Run 120V AC loads from your 12V battery bank with 2000 VA / 1600 W of continuous pure sine wave power and 4000 W peak for motor starts. When shore power, a generator or the grid is connected, the 80 A adaptive charger refills your batteries and the 50 A transfer switch passes power through to your loads. PowerControl and PowerAssist make the most of limited shore or generator power. Backed by Victron's 5-year limited warranty.

⚑ Is It Right for Your System?

Built for 12V battery banks powering standard 120V 60 Hz North American AC loads. Common uses:

  • RVs & campers
  • Boats & yachts
  • Off-grid cabins & solar
  • Home backup
  • Work trucks & vans
πŸ“ Quick check before you order:
  • Your battery bank is 12V (inverter input range 9.5–17 V).
  • Your AC loads stay within 1600 W continuous at 25Β°C, with short surges up to 4000 W. Installing somewhere hot? Check the temperature table below.
  • Your shore or generator input is up to 50 A. PowerControl lets you set a lower limit to match a smaller shore cord or generator.
  • 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

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 adds battery power so the breaker doesn't trip.

πŸ”‹

Adaptive Battery Charging

An 80 A adaptive charger with battery temperature sensing, plus a 4 A output to keep a starter battery topped up.

πŸ”—

Grows With Your System

Up to 6 in parallel; 3-phase capable. Can be set up as a split-phase system (per Victron's manual).

βš™οΈ

Programmable & Connected

Programmable relay: yes (1Γ—). VE.Bus connects it to Victron remote panels, GX devices and the VictronConnect app (with the right interface).

πŸ›‘οΈ

5-Year Victron Warranty

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

❓ Common Questions

What's the difference between VA and watts?
VA is apparent power and watts are the real power your appliances use. This MultiPlus delivers 2000 VA, which is 1600 W of continuous power at 25Β°C. Add up the watts of everything you'll run at once and stay under 1600 W.
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 4000 W, with 1600 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 use it with lithium batteries?
Yes. The charge voltages are adjustable with VEConfigure or VictronConnect, so you can match your lithium battery maker's settings. Ask us about pairing it with a GX device for battery communication.
How do I program and monitor it?
Use an MK3-USB interface with Victron's free VEConfigure software on a PC, or a VE.Bus Smart dongle with the VictronConnect app over Bluetooth. Add a GX device like the Cerbo GX for remote monitoring on Victron's VRM portal. All are sold separately.
Can I connect more than one?
Up to 6 in parallel; 3-phase capable. Can be set up as a split-phase system (per Victron's manual). Units must be the same model and configured with Victron's software.
MultiPlus 12/2000 or MultiPlus Compact 12/2000?
Both give 2000 VA / 1600 W with an 80 A charger and 50 A transfer switch. The Compact has an aluminium case, 4000 W peak and a 4 A starter battery output (13 kg). The standard 2000 VA has a steel case, 3500 W peak, IP22 and a 1 A starter output (15.5 kg).
Do I need a UL listed inverter charger?
Many RV builders, inspectors and permit offices ask for UL 458 (mobile and marine power converters) or UL 1741 (grid-tied systems). This model carries UL 458.
What size cables and fuse do I need?
Victron's installation manual lists the recommended battery cable size and DC fuse for this model. Linked above in Manuals & Downloads, or 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.
