Victron energy MultiPlus 12/3000/120 Anleitung Seite 15

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 AC input must be removed.
5.1 Standard settings: ready for use
On delivery, the MultiPlus is set to standard factory values. In general, these settings are suitable for single-unit operation.
Warning: Possibly, the standard battery charging voltage is not suitable for your batteries! Refer to the manufacturer's
docum entation, 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 MultiPlus. The MultiPlus synchronises within this range w ith the AC input frequency. The output
frequency is then equal to the input frequency.
Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz
Input voltage range
Voltage range accepted by the MultiPlus. The MultiPlus synchronises within this range w ith the AC input voltage. The output voltage is
then equal to the input voltage.
Adjustability: Low er limit: 180 - 230V
Upper limit: 230 - 270V
Note: the standard low er limit setting of 180V is intended for connection to a w eak mains supply, or to a generator w ith unstable AC
output. This setting may result in a system shut dow n w hen 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 dow n is initiated w hen the generator is stopped and revs down while the AVR simultaneously 'tries' to keep the output voltage
of the generator at 230V.
The solution is to increase the low er limit setting to 210VAC (the output of AVR generators is generally very stable), or to disconnect the
Multi(s) from the generator w hen a generator stop signal is given (w ith help of an AC contacor installed in series w ith the generator).
