It combines a low-distortion pure sine wave inverter, a smart multi-stage battery charger, and an integrated dual-AC-input transfer switch in a single aluminum enclosure, so shore power, a generator, your battery bank, and your loads all live behind one device.\u003c\/p\u003e\n\u003cp\u003eAvailable from 3 kVA to 10 kVA at 12V, 24V, or 48V DC, the Quattro 120V is lithium-compatible, UL-listed on key variants, and engineered to be paralleled, split-phased, or three-phased as your system grows.\u003c\/p\u003e\n\u003ch2\u003eWho the Quattro is built for\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCruising boats and yachts\u003c\/strong\u003e - seamless changeover between shore power and the generator with a sub-20 ms transfer, so navigation electronics and AV gear never reboot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRVs, vans, and overlanders\u003c\/strong\u003e - run roof-mounted air conditioning or an induction cooktop off a modest generator using PowerAssist to fill in the peaks from the battery bank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOff-grid cabins and tiny homes\u003c\/strong\u003e - pair with MPPT solar chargers and a battery bank for a self-consumption or fully off-grid system that still accepts a backup genset.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallers and electricians\u003c\/strong\u003e - VE.Bus communication, DIP-switch standalone setup, and full configurability via VEConfigure, VE.Bus Quick Configure, and Assistants for grid-tie and self-consumption applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy this is the Quattro, not just another inverter\/charger\u003c\/h2\u003e\n\u003ch3\u003eTwo AC inputs with an integrated transfer switch\u003c\/h3\u003e\n\u003cp\u003eThis is the headline feature. Connect both \u003cstrong\u003eshore power and a generator\u003c\/strong\u003e (or two generators) directly to the Quattro. It detects which source is live and switches automatically - no external transfer switch, no relays to size, no second enclosure on the wall.\u003c\/p\u003e\n\u003ch3\u003eTwo AC outputs, one with no-break transfer\u003c\/h3\u003e\n\u003cp\u003eThe main output rides through any source loss in under \u003cstrong\u003e20 milliseconds\u003c\/strong\u003e, fast enough that computers, plotters, satellite gear, and CPAP machines stay running through the changeover. The second AC output only energizes when an AC source is present, so non-critical loads like a water heater or air-conditioner can't drain the battery overnight.\u003c\/p\u003e\n\u003ch3\u003ePowerControl - never trip the dock pedestal again\u003c\/h3\u003e\n\u003cp\u003eSet a current limit on each AC input. The Quattro accounts for everything else drawing on that circuit and uses only the leftover capacity for charging. The 30A pedestal stops popping, the generator stops bogging, and you stop walking outside in the rain to reset breakers.\u003c\/p\u003e\n\u003ch3\u003ePowerAssist - borrow from the battery when the load spikes\u003c\/h3\u003e\n\u003cp\u003eWhen a starting load (air conditioner compressor, microwave, induction cooktop) momentarily exceeds the shore or generator capacity, the Quattro instantly supplements from the battery bank. As soon as the peak passes, that energy is recharged from the source. You can run loads larger than your inlet rating.\u003c\/p\u003e\n\u003ch3\u003eAdaptive multi-stage charging - lithium and lead-acid friendly\u003c\/h3\u003e\n\u003cp\u003eA four-stage charge profile (bulk, absorption, float, storage) with a battery temperature sensor, plus dedicated programming for lithium chemistries. The 5 kVA models charge a house bank at up to 200 A (12V), 120 A (24V), or 70 A (48V), and the 48\/10000 model delivers up to 140 A on the 48V house bank.

The pair behaves as one split-phase inverter\/charger.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between the Quattro and the MultiPlus?\u003c\/h3\u003e\n\u003cp\u003eThe MultiPlus has \u003cstrong\u003eone AC input\u003c\/strong\u003e. The Quattro has \u003cstrong\u003etwo AC inputs with a built-in transfer switch\u003c\/strong\u003e. If you have both shore power and a generator (or two generators), the Quattro saves you the cost and panel space of an external transfer switch. If you only ever connect one AC source, a MultiPlus may be all you need.\u003c\/p\u003e\n\u003ch3\u003eIs the Quattro lithium battery compatible?\u003c\/h3\u003e\n\u003cp\u003eYes. The charger supports custom voltage and current profiles for LiFePO4 and other lithium chemistries, and it integrates with Victron's VE.Bus BMS and Smart BMS over the VE.Bus communication port.\u003c\/p\u003e\n\u003ch3\u003eCan I run a Quattro off solar only, with no shore power or generator?\u003c\/h3\u003e\n\u003cp\u003eYes. Paired with Victron MPPT solar chargers and a battery bank, the Quattro runs as a true off-grid inverter. Add a Cerbo GX for monitoring and automated genset start\/stop when the battery state-of-charge drops.\u003c\/p\u003e\n\u003ch3\u003eDoes the Quattro need a Cerbo GX?\u003c\/h3\u003e\n\u003cp\u003eNot strictly. You can configure and monitor it with DIP switches, a Digital Multi Control panel, or the VictronConnect app over Bluetooth (via the VE.Bus Smart dongle). A Cerbo GX or Ekrano GX adds remote monitoring through the free VRM Portal and is highly recommended for parallel or three-phase systems.\u003c\/p\u003e\n\u003ch3\u003eHow fast does the Quattro switch between shore power and the generator?\u003c\/h3\u003e\n\u003cp\u003eUnder \u003cstrong\u003e20 milliseconds\u003c\/strong\u003e on the main output, fast enough that computers, NAS units, and most AV gear ride through the transition without rebooting.\u003c\/p\u003e\n\u003ch3\u003eAre the UL-listed variants required for U.S. installations?\u003c\/h3\u003e\n\u003cp\u003eFor many residential, commercial, and inspected installations, yes. UL 1741 listing is generally required for grid-interactive systems and for any installation requiring an inspection. Marine and off-grid installs may not require it, but UL variants are a safe default if you're unsure. Ask us if you need help confirming.\u003c\/p\u003e\n\u003ch3\u003eWhat warranty does the Quattro come with?\u003c\/h3\u003e\n\u003cp\u003eA \u003cstrong\u003e5-year limited warranty\u003c\/strong\u003e from Victron Energy, upgradable to \u003cstrong\u003e10 years\u003c\/strong\u003e for an additional 10% of the purchase price.

One AC input feeds the unit - it charges the battery when shore or generator power is present and inverts from the battery when it is not. (If you need two AC inputs, for both shore power and a generator with automatic source selection, look at the Victron Quattro instead.)\u003c\/p\u003e\n\u003ch3\u003ePowerControl - never trip the dock pedestal or bog the generator\u003c\/h3\u003e\n\u003cp\u003eSet a current limit on the AC input. The MultiPlus accounts for everything else drawing on that circuit and uses only the leftover capacity for charging. The pedestal breaker stops popping and the generator stops lugging - no walking outside in the rain to reset anything.\u003c\/p\u003e\n\u003ch3\u003ePowerAssist - borrow from the battery when the load spikes\u003c\/h3\u003e\n\u003cp\u003eWhen a starting load (air-conditioner compressor, microwave, induction cooktop) momentarily exceeds the shore or generator capacity, the MultiPlus instantly supplements the shortfall from the battery bank. As soon as the peak passes, the spare power is used to recharge the battery. You can run loads larger than your inlet rating.\u003c\/p\u003e\n\u003ch3\u003eNo-break AC output\u003c\/h3\u003e\n\u003cp\u003eThe main output rides through any source loss in under \u003cstrong\u003e20 milliseconds\u003c\/strong\u003e, fast enough that computers, plotters, satellite gear, and CPAP machines stay running through the changeover. The 3 kVA models add a \u003cstrong\u003esecond AC output\u003c\/strong\u003e that is only live when an AC source is present - so non-critical loads like a water heater can't drain the battery overnight.\u003c\/p\u003e\n\u003ch3\u003eAdaptive multi-stage charging - lithium and lead-acid friendly\u003c\/h3\u003e\n\u003cp\u003eA four-stage charge profile (bulk, absorption, float, storage) with adaptive-charge software and an included battery temperature sensor, plus dedicated programming for lithium chemistries. The 2 kVA models charge a house bank at up to 80 A (12V) or 50 A (24V); the 3 kVA models charge at up to 120 A (12V) or 70 A (24V).

That's UPS-grade behavior on a marine\/RV\/off-grid inverter, and it's the reason this is the unit professional installers wire as the AC source for any sensitive load.\u003c\/p\u003e\n\n\u003ch3\u003ePowerControl and PowerAssist on every variant\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePowerControl\u003c\/strong\u003e caps the current drawn from a shore inlet or generator so you can pull into a 15 A dock without tripping the breaker — the MultiPlus-II throttles charging back automatically. \u003cstrong\u003ePowerAssist\u003c\/strong\u003e goes the other direction: when a transient load (induction burner, microwave, AC compressor start) would exceed the shore cord rating, the inverter pulls the extra current from the battery bank in parallel. A 30 A shore cord effectively becomes a 50 A cord at peak.\u003c\/p\u003e\n\n\u003ch3\u003eAdaptive 4-stage charger with lithium and AGM profiles\u003c\/h3\u003e\n\u003cp\u003eBulk, absorption, float, and storage stages with variable absorption time. The charge profile is fully programmable for lead-acid, AGM, gel, or LiFePO4 banks over VictronConnect (with an MK3-USB) or directly from a connected GX device. Max charge current ranges from 35 A (48\/3000) up to 120 A (12\/3000 and 24\/5000) by variant — the 120 A models recover a 300 Ah lithium bank from a deep cycle in about three hours of bulk charging from generator or shore. A battery temperature sensor ships with the unit, and VE.Smart Networking pulls bank-side voltage and temperature from a Smart Battery Sense or SmartShunt so the charge profile reacts to true bank conditions rather than charger output.\u003c\/p\u003e\n\n\u003ch3\u003eVE.Bus to a Cerbo GX or Ekrano GX for full system visibility\u003c\/h3\u003e\n\u003cp\u003eWire the MultiPlus-II to a Cerbo GX or Ekrano GX over VE.Bus and the GX device shows live AC input \/ output, battery voltage and current, charge state, and inverter load on a touchscreen and in the free VRM Portal — readable from anywhere with an internet connection.\u003c\/p\u003e\n\n\u003ch3\u003eTwo units for 120\/240 V split-phase, three for three-phase\u003c\/h3\u003e\n\u003cp\u003eMost North American RVs with 50 A service and most residential off-grid builds need 120\/240 V split-phase AC, not single-phase 120 V. Wire two MultiPlus-IIs of the same variant in parallel on a single VE.Bus and you get the full split-phase output (one unit per leg) at the combined VA rating — the standard pairing for a 50 A RV inlet, a residential ESS, or a liveaboard with a 240 V well pump or dryer. Three units gives you a three-phase 18 kW system for larger off-grid setups. Up to six units total run on a single VE.Bus. A Cerbo GX (or any GX device) handles the configuration; all units must be the same model and variant.\u003c\/p\u003e\n\n\u003ch3\u003eESS and grid-tie certified on UL 1741 variants\u003c\/h3\u003e\n\u003cp\u003eThe 48\/3000\/35-50 120V (UL 1741) variant carries the anti-islanding certification required for grid-tied solar installs in most US jurisdictions. Combined with a SmartSolar MPPT and a lithium bank, it runs a full Energy Storage System — self-consumption from solar, peak-shaving against time-of-use rates, or seamless grid-backup when utility power drops.\u003c\/p\u003e\n\n\u003ch3\u003eExternal 100 A current sensor for shared circuits\u003c\/h3\u003e\n\u003cp\u003eAn optional 100 A external AC current sensor lets the MultiPlus-II measure total current on a shared circuit (e.g., when the inverter shares a sub-panel with non-MultiPlus loads), so PowerControl and PowerAssist react to actual circuit demand rather than just the inverter's own pass-through. This extends PowerControl\/PowerAssist measurement up to 100 A — useful on grid-parallel and self-consumption ESS installs.

Internal fuses aren't user-replaceable — if a fuse blows, the unit needs to go to an authorized service center for diagnosis.

If you're specifying a new install today, the MultiPlus-II is the current generation.\u003c\/p\u003e\n\n\u003ch3\u003eWill the MultiPlus-II charge LiFePO4 (lithium) batteries?\u003c\/h3\u003e\n\u003cp\u003eYes. The charger is fully programmable via VictronConnect (with an MK3-USB) or from a connected GX device. Pre-configured profiles exist for AGM, gel, flooded lead-acid, and lithium; everything else can be set with custom absorption \/ float \/ storage voltages and currents. For BMS integration, wire the BMS load-disconnect signal to the MultiPlus-II's remote on\/off port.\u003c\/p\u003e\n\n\u003ch3\u003eWhich variant do I pick for a 30-foot sailboat?\u003c\/h3\u003e\n\u003cp\u003eThe 12\/3000\/120-50 120V (UL) is the most common pairing for a 30–36 ft sailboat running a 200–400 Ah, 12V lithium house bank with a 30 A shore inlet and a small generator. If you're running a 24V system, the 24\/3000\/70-50 120V (UL) is the equivalent. For air conditioning or induction cooking that pulls more than 3 kW continuous, look at the 5000 VA variants.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need a Cerbo GX with the MultiPlus-II?\u003c\/h3\u003e\n\u003cp\u003eNot strictly. VictronConnect over an MK3-USB lets you configure and monitor the MultiPlus-II directly. A Cerbo GX or Ekrano GX adds remote access through VRM Portal, a touchscreen front-panel display, and integration with your MPPTs, BMV, and shunts so the whole system reports through one device.\u003c\/p\u003e\n\n\u003ch3\u003eCan I parallel two MultiPlus-IIs for 120\/240 V split-phase?\u003c\/h3\u003e\n\u003cp\u003eYes — that's the most common parallel configuration in North America. Two MultiPlus-IIs of the same variant in parallel on a single VE.Bus deliver 120\/240 V split-phase AC (one unit per leg) at the combined VA rating — the standard requirement for a 50 A RV inlet, a residential off-grid build, or a liveaboard running a 240 V well pump, dryer, or electric range. Three units gives you a three-phase 18 kW system, and up to six total run on a single VE.Bus for very large installs. All units must be the same model and variant, and a Cerbo GX (or any GX device) is required for configuration and monitoring.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the difference between the UL 458 and UL 1741 variants?\u003c\/h3\u003e\n\u003cp\u003eUL 458 covers safety for marine and RV inverter\/chargers operating from a battery bank. UL 1741 covers grid-tie equipment with anti-islanding (the inverter has to disconnect from the utility if the utility de-energizes). Pick UL 1741 only if you're building a grid-tied ESS install; pick UL 458 for boats, RVs, and off-grid installs not connected to the utility.\u003c\/p\u003e\n\n\u003ch3\u003eCan the MultiPlus-II 120 V run at 50 Hz?\u003c\/h3\u003e\n\u003cp\u003eYes. The default output is 60 Hz (the US\/Canada standard), but 50 Hz is user-selectable via VEConfigure. This matters in a small number of cases — for example, parts of Japan that run 50 Hz \/ 120 V power, or specific industrial loads that need 50 Hz. For US, Canadian, and Mexican installs, you'll run it at the 60 Hz default and never need to change it.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty does the MultiPlus-II come with?\u003c\/h3\u003e\n\u003cp\u003eA \u003cstrong\u003e5-year limited warranty\u003c\/strong\u003e from Victron Energy, upgradable to \u003cstrong\u003e10 years\u003c\/strong\u003e for an additional 10% of the purchase price.

Paralleling two single-120V MultiPlus-II units (one per leg) also gives split phase, but uses two enclosures and more wiring. For a 3 kVA split-phase system, the 2x120V is the simpler, more compact solution.\u003c\/p\u003e\n\u003ch3\u003eCan I get 240V when running off the battery?\u003c\/h3\u003e\n\u003cp\u003eNo. In inverter mode the unit outputs 120V on both legs (L1 and L2 internally linked), so 120V loads on either leg keep running. 240V is only available when the unit is fed from a split-phase 120\/240V shore or generator source - this is by design, to keep heavy 240V loads from draining the battery. If you need true 120\/240V split phase off the battery, install two standard 120V MultiPlus-II units in parallel (one per leg).\u003c\/p\u003e\n\u003ch3\u003eIs it lithium battery compatible?\u003c\/h3\u003e\n\u003cp\u003eYes. The charger supports custom voltage and current profiles for LiFePO4 and other lithium chemistries, and it communicates with Victron's VE.Bus BMS over the communication port.\u003c\/p\u003e\n\u003ch3\u003eWhy does the L2 output transfer slower than L1?\u003c\/h3\u003e\n\u003cp\u003eThe L1 output switches in under 18 milliseconds - fast enough that sensitive electronics ride through the transition.

If you need true 120\/240V split phase off the battery, install two standard 120V Quattro units in parallel (one per leg).\u003c\/p\u003e\n\u003ch3\u003eIs it lithium battery compatible?\u003c\/h3\u003e\n\u003cp\u003eYes.
