2. DESCRIPTION
2.1 In general
The basis of the Quattro is an extremely pow erful sine inverter, battery charger and automatic sw itch in a compact casing.
The Quattro features the follow ing additional, often unique characteristics:
Tw o AC inputs; integrated switch-over system between shore voltage and generating set
The Quattro features two AC inputs (AC-in-1 and AC-in-2) for connecting two independent voltage sources. For example, tw o
generator sets, or a mains supply and a generator set. The Quattro automatically selects the input w here voltage is present.
If voltage is present on both inputs, the Quattro selects the AC-in-1 input, to w hich normally the generating set is connected.
Tw o AC outputs
Besides the usual uninterruptable output (AC-out-1), an auxiliary output (AC-out-2) is available that disconnects its load in the
event of battery operation. Example: an electric boiler that is allow ed to operate only if the genset is running or shore pow er is
available.
Autom atic and uninterruptible switching
In the event of a supply failure or w hen the genset is sw itched off, the Quattro w ill switch over to inverter operation and take
over the supply of the connected devices. This is done so quickly that operation of computers and other electronic devices is
not disturbed (Uninterruptible Pow er Supply or UPS functionality). This makes the Quattro highly suitable as an emergency
pow er system in industrial and telecommunication applications. The maximum alternating current that can be sw itched is 30A.
Virtually unlimited power thanks to parallel operation
Up to 6 Quattros can operate in parallel. Six units 24/3000/70, for example, w ill provide 15kW / 18kVA output pow er and 420
Amps charging capacity.
Three phase capability
Three units can be configured for three-phase output. But that's not all: up to 6 sets of three units can be parallel connected to
provide 45kW / 54kVA inverter pow er and more than 1200A charging capacity.
Pow erControl – m aximum use of limited shore current
The Quattro can supply a huge charging current. This implies heavy loading of the shore connection or generating set. For both
AC inputs, therefore, a maximum current can be set. The Quattro then takes other pow er users into account, and only uses
'surplus' current for charging purposes.
- Input AC-in-1, to w hich usually a generating set is connected, can be set to a fixed maximum w ith DIP sw itches, with VE.Net
or w ith a PC, so that the generating set is never overloaded.
- Input AC-in-2 can also be set to a fixed maximum. In mobile applications (ships, vehicles), however, a variable setting by
means of a Multi Control Panel w ill usually be selected. In this w ay the maximum current can be adapted to the available shore
current in an extremely simple manner.
Pow erAssist – Extended use of your generating set and shore current: the Quattro "co-supply" feature
The Quattro operates in parallel w ith the generating set or the shore connection. A current shortfall is automatically
compensated: the Quattro draw s extra power from the battery and helps along. A current surplus is used to recharge the
battery.
This unique feature offers a definitive solution for the 'shore current problem': electric tools, dish w ashers, washing
m achines, electric cooking etc. can all run on 16A shore current, or even less. In addition, a smaller generating set can
be installed.
Solar energy
The Quattro is extremely suitable for solar energy applications. It can be used for building autonomous systems as w ell as
mains-coupled systems.
Em ergency power or autonomous operation on m ains failure
Houses or buildings provided w ith solar panels or a combined micro-scale heating and pow er plant (a pow er-generating central
heating boiler) or other sustainable energy sources have a potential autonomous energy supply w hich can be used for
pow ering essential equipment (central heating pumps, refrigerators, deep freeze units, Internet connections, etc.) during a
pow er failure. A problem in this regard, how ever, is that mains-coupled solar panels and/or micro-scale heating and pow er
plants drop out as soon as the mains supply fails. With a Quattro and batteries, this problem can be solved in a simple manner:
the Quattro can replace the m ains supply during a power failure. When the sustainable energy sources produce more
pow er than necessary, the Quattro w ill use the surplus to charge the batteries; in the event of a shortfall, the Quattro w ill supply
additional pow er from its battery energy resources.
Programmable relay
The Quattro is equipped w ith a programmable relay that by default is set as an alarm relay. The relay can be programmed for
all kinds of other applications how ever, for example as a starter relay for a generating set.
