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: 50 Hz; 60 Hz
Input frequency range
Input frequency range accepted by the MultiPlus. The MultiPlus synchronises within this range
with 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 with the
AC input voltage. The output voltage is then equal to the input voltage.
Adjustability:
Lower limit: 180 – 230 V
Upper limit: 230 – 270 V
Inverter voltage
Output voltage of the MultiPlus in battery operation.
Adjustability: 210 – 245 V
Search Mode (Applicable in stand-alone configuration only)
If search mode is 'on', the power consumption in no-load operation is decreased by approx. 70
%. In this mode the Compact, when operating in inverter mode, is switched off in case of no
load or very low load and switches on every two seconds for a short period. If the output current
exceeds a set level, the inverter will continue to operate. If not, the inverter will shut down again.
The Search Mode can be set with a DIP switch.
The Search Mode 'shut down' and 'remain on' load levels can be set with VEConfigure.
The standard settings are:
Shut down: 40 Watt (linear load)
Turn on: 100 Watt (linear load)
AES (Automatic Economy Switch)
Instead of the search mode, the AES mode can also be chosen (with help of VEConfigure only).
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.
Applicable in stand-alone configuration only.
Ground relay (see appendix B)
With this relay (H), the neutral conductor of the AC output is grounded to the chassis when the
back feed safety relay is open. This ensures the correct operation of earth leakage circuit
breakers in the output.
If a non-grounded output is required during inverter operation, this function must be turned off.
Not adjustable with DIP switches.
Battery charge curve
The standard setting is 'Four-stage adaptive with BatterySafe mode'. See Section 2 for a
description.
This is the recommended charge curve. See the help files in the software configuration
programs for other features.
