Victron Quattro 48/10000/140-100/100 Inverter Charger

Overview

The Victron Quattro 48/10000 (full designation Quattro 48/10000/140-100/100 230V) is a heavy-duty inverter/charger from Victron Energy with two independent AC inputs and an integrated transfer switch. It supplies 10000 VA continuous at 25 °C from a 48 V battery, charges at up to 140 A and can pass through up to 100 A on each of its two inputs. The defining idea of the Victron Quattro 48/10000 is that it can be connected to two separate AC sources at the same time, for example the public grid and a standby generator, or two generators, and it automatically connects to whichever source is active.

Seven Star LLC supplies the Victron Quattro 48/10000 in Oman and the GCC, with engineering support in Muscat. Sites that combine grid power, diesel generation, batteries and PV, such as remote camps, farms, desalination units, telecom hubs and large villas, often need exactly this kind of source management. Buyers searching for a solar inverter in Muscat for a hybrid system with a generator backup frequently end up comparing the Victron Quattro 48/10000 with single-input inverters, and the two-input design is usually what decides it.

Operating Principle of the Victron Quattro 48/10000

As a general description, an inverter/charger with an integrated transfer switch works in two directions: it charges the battery from available AC, and it inverts battery DC to AC when no source is present. In the Victron Quattro 48/10000, the main AC output has a no-break function: when the active source fails or is disconnected, the inverter takes over within less than 20 milliseconds so that computers and electronic equipment keep running. A second output is live only while one of the AC inputs is present, so non-critical loads such as water heaters do not discharge the battery.

Because the Victron Quattro 48/10000 is a powerful charger, Victron explains that it would draw a lot of current from a generator or shore supply if left unchecked. PowerControl solves this by allowing a current limit on each AC input; the unit then accounts for other AC loads and uses only spare capacity for charging. PowerAssist adds battery power to the source when short load peaks exceed the limit and recharges the battery when demand falls. With Assistants software the Victron Quattro 48/10000 can also be configured for off-grid, grid-interactive and self-consumption systems that include grid-tie PV inverters or MPPT solar chargers, and loss-of-mains detection software is available.

Engineering Design of the Victron Quattro 48/10000

The Victron Quattro 48/10000 has an aluminium enclosure in blue RAL 5012 with IP20 protection, pollution degree 2 and overvoltage category III, so it is designed for a clean indoor plant room or equipment shelter. It measures 470 x 350 x 280 mm (h x w x d) and weighs 51 kg. Battery connection is by four M8 bolts (two positive, two negative) and AC connections are on M6 bolts. Operating temperature is −20 to +60 °C with up to 95 % non-condensing humidity and a maximum altitude of 2000 m. The AC inputs accept 187 to 250 VAC at 50/60 Hz with cos phi above 0.8, and the short-time withstand current (ICw) for the 10 kVA model is 10 kA for 30 ms.

Inverter output for the Victron Quattro 48/10000 is 230 VAC ± 2 % at 50 Hz ± 0.1 % (adjustable to 60 Hz), with continuous output of 8000 W at 25 °C, 6500 W at 40 °C and 4500 W at 65 °C, peak power of 20000 W, maximum continuous output current of 37 A and maximum output fault current of 100 A for one second. DC input range is 38 to 60 V and DC input current is 235 A. Maximum efficiency is 96 %. Three programmable relays can be set for alarms, DC undervoltage or generator start/stop, and the 50 A auxiliary output switches off when no external AC source is available. Monitoring and control options include battery monitors, the Multi Control Panel, Cerbo GX or other GX devices, Bluetooth and USB or RS232 connections.

Key Features

The main capabilities of the Victron Quattro 48/10000, as listed by Victron, are summarised here.

• Two AC inputs with an integrated transfer switch connect automatically to the active source, such as grid or generator.
• Each AC input carries up to 100 A of feed-through current, with an adjustable current limit for PowerControl.
• No-break main output with transfer below 20 ms, plus a second output that runs only when AC input is present.
• PowerAssist supplements weak grid or generator supply with battery power during load peaks.
• Three units can be configured for three-phase output, and up to four sets of three 15 kVA units can be paralleled.
• Assistants enable off-grid, grid-interactive and self-consumption systems with PV inverters or MPPT chargers.
• Three programmable relays support alarm signalling and automatic generator start/stop.
• Remote monitoring and configuration are available through GX devices and the free VRM portal.

Industrial Applications

In Oman the Victron Quattro 48/10000 fits remote and semi-remote sites where both grid and generator are present or where two generators alternate: construction and oilfield camps, desert farms with irrigation pumps, telecom and SCADA shelters, small desalination and water pumping stations, mountain resorts and holiday homes in Jebel Akhdar and Dhofar. The 140 A charger and 10 kVA output support substantial battery banks, which lets generator run hours be cut and allows silent operation at night.

For larger facilities, three units of the same model can be configured as a three-phase system, and Victron data shows that parallel sets of 15 kVA units can scale to 180 kVA. Seven Star LLC supplies the Victron Quattro 48/10000 with GX monitoring, battery monitors and compatible battery systems, and our engineers in Muscat assist clients in Oman and the GCC with source switching logic, generator sizing and battery capacity planning.
