Victron Energy Quattro 12/5000/220-100/100 120V (QUA125021100): a pure sine wave inverter, battery charger and dual-input automatic transfer switch in one unit. Run 120V AC loads from your 12V battery bank with 5000 VA / 4000 W of continuous pure sine wave power and 10,000 W peak. Two AC inputs, each with a 100 A transfer switch, let you connect shore power and a generator at the same time, and the Quattro switches to the active source automatically. Whenever AC is available, the 220 A charger refills your batteries; if the AC source drops out, the no-break output keeps computers and electronics running. PowerControl, PowerAssist and Victron GX/ESS compatibility make it a go-to for larger RV, marine, off-grid and home backup systems. 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 from two AC sources. Common uses:

  • Large RVs & motorhomes
  • Yachts & workboats
  • Off-grid homes & cabins
  • Home backup with generator
  • Commercial & remote sites
📏 Quick check before you order:
  • Your battery bank is 12V (inverter input range 9.5–17 V). Victron recommends at least 800 Ah (800–2400 Ah).
  • You need 120V single-phase output. Need 240V? Two identical units can be set up for 120/240V split phase, or look at the Quattro-II 2x120V in the table below.
  • Your AC loads stay within 4000 W continuous at 25°C, with short surges up to 10,000 W.
  • Each AC input carries up to 100 A. PowerControl lets you set a lower limit for a small generator or shore pedestal.
  • Plan for battery cables, a DC fuse and AC wiring sized per Victron's manual (not included).
  • Need UL for an RV, inspection or permit? This version isn't UL listed. See the UL models in the table below.

Why Choose a Victron Quattro

🔌

Two AC Inputs

Connect shore power and a generator, or two generators. The Quattro picks the live source automatically, with AC-in-1 taking priority.

💪

Two 100 A Transfer Switches

Each input passes up to 100 A through to your loads, so a large AC panel keeps running on shore or generator power.

⚖️

PowerControl & PowerAssist

Set a separate current limit for each input. When loads spike past it, the Quattro adds battery power so the breaker doesn't trip.

🖥️

No-Break Output

If the AC source fails, the main output switches to inverter power fast enough that computers keep running. A second output powers loads only while AC is present.

🔗

Expandable

Two identical units give 120/240V split phase, three give three-phase, and up to 6 can run in parallel per Victron's manual.

🛡️

5-Year Victron Warranty

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

🔋 Charging Your Batteries

🔋

Lithium or Lead-Acid

Adaptive 4-stage charging with default voltages of 14.4 V / 13.8 V / 13.2 V (absorption / float / storage). Adjust them with VEConfigure or VictronConnect, or let a GX device and your lithium BMS control charging.

🔌

From Either AC Input

Charges from whichever AC input is live, shore or generator, and PowerControl keeps it within your source's limit.

🚤

Starter Battery Output

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

🌡️

Temperature Compensation

A battery temperature sensor adjusts charging for hot and cold conditions. The sensor comes with the unit.

❓ Common Questions

What's the difference between a Quattro and a MultiPlus?
The Quattro has two AC inputs instead of one, each with a 100 A transfer switch, so you can connect shore power and a generator at the same time. It also has three programmable relays and a larger charger than most MultiPlus models.
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 10,000 W, with 4000 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 a current limit for the input, 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 Quattro-II 2x120V 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 Quattro can take charge commands directly from a compatible lithium battery's BMS.
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?
No, this version isn't UL listed. If you need UL 458 or UL 1741 for an RV, inspection or permit, check the UL models in the comparison table.
Is the charger 220 A or 200 A?
Victron's model name, price list and manual give 220 A. One table in the datasheet lists 200 A.
What size cables and fuse do I need?
For this model, Victron's manual calls for an 800 A DC fuse and 2× 120 mm² (about 4/0 AWG) cable per terminal for runs up to 5 m, with a battery bank of 800–2400 Ah. 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.
