Victron Quattro 12V 3000-5000W

Like the MultiPlus, the Victron Quattro is an all-in-one inverter and charger. In addition, the Quattro has two AC inputs and automatically connects to the active source. Its many features include a pure sine wave inverter, adaptive charging, hybrid PowerAssist technology, and multiple system integration functions, such as three-phase or single-phase operation and parallel operation.

Two AC inputs with integrated transfer switch
The Victron Quattro can be connected to two independent AC sources, for example the mains and a generator, or two generators. The Victron Quattro automatically switches to the active source.

Two AC outputs
The main output has uninterruptible functionality. The Victron Quattro takes over the power supply to the connected loads in the event of a power failure or if the shore or generator power is interrupted. This happens so quickly (in less than 20 milliseconds) that computers and other electronic devices can continue to function without interruption.
The second output is only active if AC power is available at one of the Quattro inputs. Loads that must not discharge the battery, such as a boiler, can be connected to this output.

Virtually unlimited power thanks to parallel operation
Up to 6 Victron Quattro units can be connected in parallel. For example, six 48/10000/140 units can achieve an output power of 48kW / 60kVA with a charging capacity of 840A.

Three-phase operation
Three units can be configured for three-phase output. But that's not all: up to 6 sets of three units can be connected in parallel for an inverter capacity of 144kW / 180kVA and a charging capacity of more than 2500A.

PowerControl - Make the most of limited generator, shore, or grid power
The Victron Quattro is a very powerful battery charger. This means a heavy load on the generator or shore connection (up to 16A per 5kVA Quattro at 230VAC). A current limit can be set for each AC input. The Quattro then takes other power consumers into account and only uses the power that is still 'left over' for charging, so that the generator or shore connection does not become overloaded.

PowerAssist - Do more with generator or shore power
This feature adds another dimension to the PowerControl principle because the Quattro supplements the capacity of the alternative source. While peak power is often only needed briefly, the Quattro ensures that insufficient grid or generator power is immediately compensated with power from the battery. When the load decreases, the reserve power is used to recharge the battery.

This powerhouse has all the unique features of the "standard" MultiPlus and also has two 230V inputs (e.g. shore and/or generator) and two outputs so that you can set your own priorities. Input voltage range : 9.5-17 Vdc Continuous power : 4,500W Peak power : 10,000W Output voltage : 230 Vac Charging current : 200 A Dimensions (h x w x d in mm) : 470x350x280 Two AC inputs; integrated transfer system between shore power and generator The Quattro has two AC inputs to which two independent power sources can be connected. For example, 2 generators, or grid power and a generator. The Quattro automatically selects the input where power is available Two AC outputs All Quattro and various Multi inverter chargers now have two AC outputs. In addition to the uninterruptible main output, a second output is available that disconnects connected loads when the batteries are being used. For example, it is the perfect solution to prevent a boiler from discharging your battery. Virtually unlimited power thanks to parallel operation. Two to six Quattro units can be connected in parallel. For example, 6 Quattro units 24/5000/120 can achieve an output power of 25kW / 30kVA, and a charging current of 720A. Solar energy: AC power available despite a grid power failure The Quattro can be used for both off-grid and grid-connected solar energy systems. Easy to install, and settings are easy to adjust. If you want to change some setting, you can do so with DIP switches in the Quattro, with a VE.Net panel, or with free software and a PC.
