EN Appendix
The Quattro provides seamless transfer (no-break functionality) on output L1. Output L2 connects to the inverter after a short
delay.
Note: this product is not suitable for a single phase 230V or 240V supply. (see section 2.3)
Automatic and uninterruptible switching (on phase L1 only)
In the event of a supply failure or when the generating set is switched off, the Quattro will 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 Power Supply or UPS functionality). This makes the Quattro highly suitable as an emergency
power system in industrial and telecommunication applications.
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 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 75kW / 90kVA inverter power and more than 2000A charging capacity.
PowerControl – maximum use of limited shore current
For each AC input a maximum current can be set. The Quattro then takes other power users into account, and only uses
'surplus' current for charging purposes.
When AC is present on one of the inputs, the inverter/charger of the Quattro connects to the preferred input leg (L1-1 or L1-2).
PowerControl will therefore be active on the preferred input leg only.
─ L1-1 of input AC-in-1, to which usually a generating set is connected, can be set to a fixed maximum with DIP switches,
with VE.Net or with a PC, so that the generating set is never overloaded.
─ L1-2 of 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 will usually be selected. In this way the maximum current can be adapted to the
available shore current in an extremely simple manner.
PowerAssist – Extended use of your generating set and shore current: the Quattro ‘co-supply’ feature
The Quattro operates in parallel with the generating set or the grid/shore connection. A current shortfall is automatically
compensated: the Quattro draws extra power from the battery and helps along.
Solar energy
The Quattro is extremely suitable for solar energy applications. It can be used for building autonomous systems as well as grid-
connected systems.
Emergency power or autonomous operation on mains failure
Houses or buildings with solar panels or a combined micro-scale heating and power plant (a power-generating central heating
boiler) or other sustainable energy sources have a potential autonomous energy supply which can be used for powering
essential equipment (central heating pumps, refrigerators, deep freeze units, Internet connections, etc.) during a grid-power
failure. A problem in this regard, however, is that a grid connected solar inverter and/or micro-scale heating and power 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 grid during a power failure. When the sustainable energy sources produce more power than
needed, the Quattro will use the surplus to charge the batteries; in the event of a shortfall, the Quattro will supply additional
power from the battery.
Multi-functional relay
The Quattro is equipped with a multi-functional relay that by default is programmed as an alarm relay. The relay can be
programmed for all kinds of other applications, for example as a starter relay for a generating set.
Programmable with DIP switches, VE.Net panel or personal computer
The Quattro is supplied ready for use. Three options are available for changing certain settings if desired:
─ The most important settings (including parallel operation of up to three devices and split phase or 3-phase operation) can
be changed in a very simple manner, using DIP switches.
─ All settings, with exception of the multi-functional relay, can be changed with a VE.Net panel.
─ All settings can be changed with a PC and free of charge software, downloadable from our website

2.2 Battery charger
Adaptive 4-stage charging characteristics: bulk – absorption – float – storage
The microprocessor-driven adaptive battery management system can be adjusted for various types of batteries. The adaptive
function automatically adapts the charging process to battery use.
The right amount of charge: variable absorption time
When only shallow discharges occur (a yacht connected to shore power for example) the absorption time is kept short in order
to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that
the battery is completely recharged.
Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen,
the Phoenix charger will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once
the gassing voltage has been reached
