Inverter voltage
Output voltage of the Quattro in battery operation.
Adjustability: 210 – 245V
Stand-alone / parallel operation / 2-3 phase setting
Using several devices, it is possible to:
increase total inverter power (several devices in parallel)
•
create a split-phase system (only for Quattro units with 120V output voltage)
•
create a 3-phase system.
•
To this end, the devices must be mutually connected with RJ45 UTP cables. Standard device settings, however, are such that each
device operates in stand-alone operation. Reconfiguration of the devices is therefore required.
AES (Automatic Economy Switch)
If this setting is turned 'on', the power consumption in no-load operation and with low loads is decreased by approx. 20%, by slightly
'narrowing' the sinusoidal voltage. Not adjustable with DIP switches. Only applicable in stand-alone configuration.
Ground relay (see appendix B)
With this relay (H), the neutral conductor of the AC output is grounded to the casing when the back feed safety relays in the AC-in-1
and the AC-in-2 inputs are open. This ensures the correct operation of earth leakage circuit breakers in the outputs.
If a non-grounded output is required during inverter operation, this function must be turned off. (See also Section 4.5)
Not adjustable with DIP switches.
Charging characteristics
The standard setting is 'Four-stage adaptive with BatterySafe mode'. See Section 2 for a description.
This is the best charging characteristic. See the help files in the software configuration programs for other features.
'Fixed' mode can be selected with DIP switches.
Battery type
The standard setting is the most suitable for Victron Gel Deep Discharge, Gel Exide A200, and tubular plate stationary batteries
(OPzS). This setting can also be used for many other batteries: e.g. Victron AGM Deep Discharge and other AGM batteries, and many
types of flat-plate open batteries. Four charging voltages can be set with DIP switches.
Absorption time
This depends on the bulk time (adaptive charging characteristic), so that the battery is optimally charged. If the 'fixed' charging
characteristic is selected, the absorption time is fixed. For most batteries, a maximum absorption time of eight hours is suitable. If an
extra high absorption voltage is selected for rapid charging (only possible for open, flooded batteries!), four hours is preferable. With
DIP switches, a time of eight or four hours can be set. For the adaptive charging characteristic, this determines the maximum
absorption time.
Storage voltage, Repeated Absorption Time, Absorption Repeat Interval
See Section 2. Not adjustable with DIP switches.
Bulk Protection
When this setting is 'on', the bulk charging time is limited to 10 hours. A longer charging time could indicate a system error (e.g. a
battery cell short-circuit). Not adjustable with DIP switches.
Generator (AC-in-1) / Shore current (AC-in-2)
These are the standard current limit settings for which PowerControl and PowerAssist come into operation. See Section 2, the book
'Energy Unlimited', or the many descriptions of this unique feature on our website
UPS feature
If this setting is 'on' and AC on the input fails, the Quattro switches to inverter operation practically without interruption. The Quattro
can then be used as an Uninterruptible Power Supply (UPS) for sensitive equipment such as computers or communication systems.
The output voltage of some small generating sets is too unstable and distorted for using this setting – the Quattro would continually
switch to inverter operation. For this reason, the setting can be turned off. The Quattro will then respond less quickly to voltage
deviations on AC-in-1 or AC-in-2. The switchover time to inverter operation is consequently slightly longer, but most equipment
(computers, clocks or household equipment) is not adversely impacted.
Recommendation: Turn the UPS feature off if the Quattro fails to synchronise, or continually switches back to inverter operation.
