Victron Quattro 48/10000/140-100/100 120V (UL 1741) | QUA483100102

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.
