Dual-input 48V inverter and charger
A 10,000VA Victron 120V inverter/charger with 140A battery charging, dual 100A AC inputs, PowerAssist, VE.Bus networking, and UL 1741 listing.
The Victron Quattro 48/10000/140 is a heavy-duty 48V 10000VA inverter charger engineered for whole-building off-grid systems, luxury marine installations, large RVs, and commercial mobile power. Part QUA483100102 combines an 8,000W continuous pure sine wave inverter, a 140A battery charger, two independent 100A AC input paths, and automatic generator/shore-power source selection in one integrated 120V power hub.
Every number in 48/10000/140-100/100 describes a major part of the system.
“48” identifies the battery-bank class. “10000” is the inverter’s 10,000VA apparent-power rating. “140” is its maximum DC charging current. “100/100” identifies two AC input paths, each rated for up to 100A feed-through through the integrated transfer architecture.
The Quattro supplies 8,000W continuous real power at 25°C, 6,500W at 40°C, and 20,000W peak output. A single unit powers demanding 120V loads; matched units are required for true 120/240V split-phase service.
Hardwire two independent AC sources and let the Quattro select the active input. AC-in-1 normally receives priority when both sources are live, making it the typical generator connection while AC-in-2 serves shore or utility power.
When an approved AC source is present, the Quattro can deliver up to 140A to a compatible 48V battery bank. Charge current and voltages must be programmed within the battery and BMS limits.
Manage large AC sources, limited shore connections, critical loads, and battery backup from one platform.
PowerControl limits source demand so charging does not overload the configured generator or shore connection. PowerAssist goes further by supplementing the selected AC source with battery/inverter power during short peaks, then using available surplus to recharge the battery bank.
AC-Out-1 provides backed-up, no-break power for critical loads. AC-Out-2 is reserved for loads that should operate only when generator, shore, or grid power is present and automatically disconnects during battery-only operation.
High-output inversion, dual-source transfer, adaptive charging, expansion, and connected control.
Build beyond one inverter with matching units, VE.Bus networking, and professional commissioning.
Two matching 120V Quattros can be configured for 120/240V split-phase service, while three matching units can form a three-phase system. Parallel operation increases available power on a phase. Large systems require identical compatible units, matching firmware, correct RJ45 UTP cabling, approved configuration tools, and qualified system design.
Current Victron documents publish different maximum counts for some parallel and grouped three-phase architectures, so the final quantity must be verified against the exact firmware, current manual, certification requirements, and project topology.

Size the battery bank, DC protection, conductors, AC distribution, grounding, and ventilation as one coordinated system.
Victron lists an external 400A DC fuse, a 250–1,000Ah battery-bank range, dual positive and negative DC cables, and substantial AC conductor/protection requirements for this model. The correct fuse class, interrupt rating, cable size, source protection, and distribution design depend on the battery fault current, cable run, ambient temperature, installation method, and applicable code. Do not treat a disconnect switch as a substitute for overcurrent protection.
Common questions about dual AC inputs, inverter output, split-phase systems, fusing, wiring, monitoring, and installation.
The main difference is the AC-source architecture. A MultiPlus normally has one AC input, while the Quattro has two independent AC inputs for sources such as a generator and shore power or utility power. The Quattro automatically selects the active source; when both are available, AC-in-1 has priority.
48 identifies the nominal battery-bank class. 10000 is the 10,000VA inverter rating. 140 is the maximum house-bank charge current. The 100/100 designation identifies two AC input paths, each with up to 100A maximum feed-through capacity through the integrated transfer system.
A single QUA483100102 supplies 120V AC at 60Hz. Two matching 120V Quattro units can be configured as a 120/240V split-phase system using VE.Bus and the correct Victron configuration tools. Split-phase installation and commissioning should be completed by qualified personnel.
No. Both sources may remain connected, but the Quattro selects one active source rather than combining the two AC inputs. AC-in-1 normally receives priority when voltage is available on both inputs. PowerAssist can supplement the selected source with battery/inverter power when configured correctly.
The inverter is rated at 10,000VA apparent power, 8,000W continuous output at 25°C, 6,500W at 40°C, and 20,000W peak power. The integrated charger can supply up to 140A to a compatible 48V battery bank, subject to temperature, settings, battery limits, and available AC input power.
Victron's current 120V manual lists a 400A external DC fuse and a recommended 250–1,000Ah battery bank. For a total cable run of 0–5 meters, it lists two 50mm² positive cables and two 50mm² negative cables; for 5–10 meters, two 95mm² cables per polarity. Local codes and the required DC interrupt rating still govern the final fuse and cable design.
AC-Out-1 is the backed-up output. It remains powered by the inverter when both external AC sources are unavailable, with transfer occurring in less than 20 milliseconds under normal conditions. AC-Out-2 is intended for non-critical loads and switches off during battery operation; it reconnects after external AC returns and the source has stabilized.
Yes, but Bluetooth is not built directly into this Quattro. Connect it to a Cerbo GX or Ekrano GX through VE.Bus for system monitoring and VRM remote access, or add a compatible VE.Bus Smart Dongle for local VictronConnect access. An MK3-USB interface is used for detailed computer configuration and diagnostics.
Yes. Matching units can be configured for parallel, split-phase, or three-phase operation through VE.Bus. Victron's current manual documents up to six Quattros in parallel, while current datasheet examples publish different grouped limits for larger three-phase systems. Confirm the permitted count, firmware, certification, and design method for the exact project.
No. QUA483100102 is the 120V, 60Hz, UL 1741 version. Victron lists QUA483100300 as the separate 120V VE.Bus 50/60Hz model. Use the exact part number required by the installation, jurisdiction, and AC system.
No. The enclosure is rated IP21. Victron requires a dry, heat-resistant, well-ventilated installation with at least approximately 10cm of cooling clearance and no direct rain, snow, standing water, or battery-gas exposure. Vertical wall mounting is preferred for cooling.
