Victron energy Quattro 48V/3000VA/35A-50/50/120V Manual page 14

5. CONFIGURATION
- Settings may only be changed by a qualified electrical engineer.
- Read the instructions thoroughly before implementing changes.
- During setting of the charger, the DC fuse in the battery connections must be
removed.
5.1 Standard settings: ready for use
On delivery, the Quattro is set to standard factory values. In general, these settings are selected for single-unit operation.
Settings, therefore, do not require changing in the event of stand-alone use.
Warning: Possibly, the standard battery charging voltage is not suitable for your batteries! Refer to the manufacturer's
documentation, or to your battery supplier!

5.2 Explanation of settings
Settings that are not self-explanatory are described briefly below. For further information, please refer to the help files in the
software configuration programs (see Section 5.3).
Inverter frequency
Output frequency if no AC is present at the input.
Adjustability: 50Hz; 60Hz
Input frequency range
Input frequency range accepted by the Quattro. The Quattro synchronises within this range with the voltage present on AC-in-1
(priority input) or AC-in-2. Once synchronised, the output frequency will be equal to the input frequency.
Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz
Input voltage range
Voltage range accepted by the Quattro. The Quattro synchronises within this range with the voltage present on AC-in-1 (priority
input) or on AC-in-2. After the back feed relay has closed, output voltage will be equal to input voltage.
Adjustability:
Lower limit: 90 - 120V
Upper limit: 120 - 130V
Note: the standard lower limit setting of 90V is intended for connection to a weak mains supply, or to a generator with unstable
AC output. This setting may result in a system shut down when connected to a 'brushless, self excited, externally voltage
regulated, synchronous AC generator' (synchronous AVR generator). Most generators rated at 10kVA or more are synchronous
AVR generators. The shut down is initiated when the generator is stopped and revs down while the AVR simultaneously 'tries'
to keep the output voltage of the generator at 120V.
The solution is to increase the lower limit setting to 110VAC (the output of AVR generators is generally very stable), or to
disconnect the Multi(s) from the generator when a generator stop signal is given (with help of an AC contacor installed in series
with the generator).
