Quattro 5 kVA
120/240V series Inverter/Charger
Two AC inputs with integrated transfer switch The Quattro can be connected to two independent AC sources, for example shore-side (grid-) power and a generator, or two generators. The Quattro will automatically connect to the active source.
120/240 V input and output The two AC inputs can be supplied from a split phase (up to 60 A per phase), dual AC (up to 60 A total), or single phase AC (up to 50 A) source. The AC inputs can be connected to a different type of supply: one input may for example be connected to a split phase source, and the other to a single phase source.
When an AC source is available, the Quattro will feed through the AC to its output. The output will therefore mirror the AC input.
The inverter/charger connects to the neutral and the preferred input line (L1). Power needed to charge the batteries will therefore be drawn from L1.
The Quattro switches to inverter operation when no AC source is available. The inverter output is 120 V single phase. In Invert mode, the Quattro connects both output lines (L1 and L2) together to provide 120 VAC to loads on either line. Any 240 VAC loads will therefore be supplied only when the Quattro is supplied by a split phase AC source. This prevents heavy loads such as water heaters or 240 V air conditioners from discharging the battery.
The Quattro provides seamless transfer (no-break functionality) on output L1. Output L2 connects to the inverter after a short delay.
PowerControl - Dealing with limited generator, shore-side or grid power The Quattro is a very powerful battery charger. It will therefore draw a lot of current from the generator or shore side supply (34 A per Quattro at 120 VAC). A current limit can be set for L1 on both AC inputs. The Quattro will then take account of other AC loads and use whatever is spare for charging, thus preventing the generator or shore supply from being overloaded.
PowerAssist - Boosting shore or generator power This feature takes the principle of PowerControl to a further dimension allowing the Quattro to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period, the Quattro will make sure that insufficient shore or generator power is immediately compensated for by power from the battery (L1 inputs only). When the load reduces, the spare power is used to recharge the battery.
Virtually unlimited power thanks to parallel operation Up to 6 Quattro’s can operate in parallel. Six units 24/5000/120, for example, will provide 25kW / 30kVA output power and 720 Amps charging capacity.
Three phase and split phase capability Three resp. two units can be configured for three-phase resp. split phase output. But that’s not all: up to 6 units can be paralleled per phase (max 18 units in a three phase system and max. 12 units in a split phase system).
Solar energy: AC power available even during a grid failure The Quattro can be used both in off-grid and on-grid connected PV, and in other alternative energy systems.
A grid connected PV system will shut down when the grid fails! Not anymore with a Quattro and batteries A PV or other grid connected alternative energy system is a big investment. But it is incomplete: it will shut down in the event of a grid failure. A Quattro plus battery can solve this deficiency: the Quattro will replace the grid when needed, keeping the alternative energy system ‘on line’. During a power outage the system continues to function ‘on its own’, as a small autonomous grid. The Quattro will stabilise the ‘mini grid’ by taking power from it to recharge the battery when power generation exceeds consumption, and by supplying additional power when demand exceeds the supply from the alternate sources. In addition, the Quattro can be used to connect an AC generator to the mini grid.
System configuring has never been easier After installation, the Quattro is ready to go. If settings have to changed, this can be done in a matter of minutes with a new DIP switch setting procedure. Even parallel and 3-phase operation can be programmed with DIP switches: no computer needed! Alternatively, VE.Net can be used instead of the DIP switches. And sophisticated software (VE.Bus Quick Configure and VE.Bus System Configurator) is available to configure several new, advanced, features.
