Victron energy Quattro 12/5000/200-50/30-230V Manual página 15

4.4 Connection options
4.4.1 Starter battery (connection terminal G, see appendix A)
The Quattro has a connection for charging a starter battery. Output current is limited to 4A.
4.4.2 Voltage sense (connection terminal E, see appendix A)
For compensating possible cable losses during charging, two sense wires can be connected with which the voltage direct on
the battery or on the positive and negative distribution points can be measured. Use at least wire with a cross-section of
0,75mm2.
During battery charging, the Quattro will compensate the voltage drop over the DC cables to a maximum of 1 Volt (i.e. 1V over
the positive connection and 1V over the negative connection). If the voltage drop threatens to become larger than 1V, the
charging current is limited in such a way that the voltage drop remains limited to 1V.
4.4.3 Temperature sensor (connection terminal H, see appendix A)
For temperature-compensated charging, the temperature sensor (supplied with the Quattro) can be connected. The sensor is
isolated and must be fitted to the negative terminal of the battery.
4.4.4 Remote control
The Quattro can be remotely controlled in two ways:
- With an external switch (connection terminal L, see appendix A). Operates only if the switch on the Quattro is set to "on".
- With a remote control panel (connected to one of the two RJ48 sockets B, see appendix A). Operates only if the switch on the
Quattro is set to "on".
Using the remote control panel, only the current limit for AC-in-2 can be set (in regard to PowerControl and PowerAssist).
The current limit for AC-in-1 can be set with DIP switches or by means of software.
Only one remote control can be connected, i.e. either a switch or a remote control panel.
4.4.5. Programmable relay
The Quattro is equipped with a programmable relay that by default is set as an alarm relay. The relay can be programmed for
all kinds of other applications however, for example to start a generator (VEConfigure software needed).
4.4.6 Auxiliary AC output (AC-out-2)
Besides the usual uninterruptable output, a second output (AC-out-2) is available that disconnects its load in the event of
battery operation. Example: an electric boiler or air conditioner that is allowed to operate only if the genset is running or shore
power is available.
In case of battery operation, AC-out-2 is switched off immediately. After the AC supply has become available, AC-out-2 is
reconnected with a delay of 2 minutes, this allow a genset to stabilise prior to connecting a heavy load.
4.4.7 Connecting Quattro's in parallel (see appendix C)
The Quattro can be connected in parallel with several identical devices. To this end, a connection is established between the
devices by means of standard RJ45 UTP cables. The system (one or more Quattro's plus optional control panel) will require
subsequent configuration (see Section 5).
In the event of connecting Quattro units in parallel, the following requirements must be met:
- A maximum of six units connected in parallel.
- Only identical devices with the same power ratings may be connected in parallel.
- Battery capacity should be sufficient.
- The DC connection cables to the devices must be of equal length and cross-section.
- If a positive and a negative DC distribution point is used, the cross-section of the connection between the batteries and the
DC distribution point must at least equal the sum of the required cross-sections of the connections between the distribution
point and the Quattro units.
- Place the Quattro units close to each other, but allow at least 10 cm for ventilation purposes under, above and beside the
units.
- UTP cables must be connected directly from one unit to the other (and to the remote panel). Connection/splitter boxes are not
permitted.
- A battery-temperature sensor need only be connected to one unit in the system. If the temperature of several batteries is to be
measured, you can also connect the sensors of other Quattro units in the system (with a maximum of one sensor per Quattro).
Temperature compensation during battery charging responds to the sensor indicating the highest temperature.
- Voltage sensing must be connected to the master (see Section 5.5.1.4).
- If more than three units are connected in parallel in one system, a dongle is required (see Section 5).
- Only one remote control means (panel or switch) can be connected to the system.
4.4.8 Three-phase configuration (see appendix C)
Quattro's can also be used in 3-phase configuration. To this end, a connection between the devices is made by means of
standard RJ45 UTP cables (the same as for parallel operation). The system (Quattro's plus an optional control panel) will
require subsequent configuration (see Section 5).
Pre-requisites: see Section 4.4.7.
