The Victron Quattro 8000VA inverter charger is perhaps the largest on the market that can still operate at 24V and 48V. From boats to military installations, the superior quality of Victron Quattro inverter chargers makes them ideal for a huge range of top-end remote power and power backup systems. The added function of being able to manage two different AC sources, as well as power from the DC battery bank, and switch between all three, makes them an invaluable tool for the power management market.
Two AC inputs with integrated transfer switch:
The Quattro can be connected to two independent AC sources, for example shorepower or the national grid, as well as a generator, or even two generators. Using the advanced transfer switch, the Quattro will automatically switch between sources should one or more of them fail. This all takes place within 12 milliseconds, with a very slight dip in voltage, so that 99.9% of electrical devices will not register the change.
Two AC Outputs:
The main AC output is 'always on', whereas the secondary output is only active when the Victron Quattro is connected to an AC input source. This allows you to separate your electrical consumers into essential and non-essential groups. For example, it is advisable to connect water heaters or air-conditioning to the 'non-essential' AC2 connection.
Virtually unlimited power:
Up to 10 Victron Quattro inverter chargers can be set up to operate in parallel, so that ten 8000W units, for example, will provide 70kW - 80kW of usable power and a massive 2000A charging capacity.
Three phase capability:
By connecting three Victron Quattro units together, they can supply a three-phase output. In addition, up to 10 trios can be operated in parallel, supplying up to 300kW of power and >4000A in battery charging!
Since the Victron Quattro is a very powerful inverter charger, the maximum current draw from generator or shore-side sources can be limited. In this case, the Quattro will divert the necessary current to the operating devices, only feeding waht remains to the batteries. This prevents any overload on the AC sources.
When the draw on the AC sources has been limited by PowerControl, the Quattro will 'boost' the available AC current with power from the battery bank. When power consumption falls below the limited AC input level, the Victron Quattro then stops drawing on the batteries and instead returns to using surplus AC input power to recharge the batteries.
The Quattro can be used in off grid as well as grid connected PV systems.
Simple installation and easy configuration:
After installing, the Quattro is generally ready to go, straight out of the box. In some cases, however, you may wish to change some settings to optimise the Quattro to your exact installation, such as changing battery types or power limits. This can be done simply and painlessly, using either the integrated DIP switches or by using the 'VE.Bus Quick Configure' and 'VE.Bus System Configurator', which is available free from victronenergy.com
