7. OPERaTION

Which consumers that are operated with mains voltage (230 V/aC, 50 Hz) can be con-
nected to a inverter?
Generally, all consumers can be operated on a inverter.
However, many consumers have a higher power consumption at the moment of switching on
than their rating plate says. This does not have any great importance when connecting to the
public mains, since there are always the corresponding power reserves.
The inverter is limited in its output. However, it may supply a peak output briefly to balance out
the high consumption at the moment of activation of the consumer.
If the consumption at the moment of activation of the consumer is higher than the peak output
of the inverter (or if it takes too long), the overload protection of the inverter will be activated.
The consumer cannot be connected and operated at the inverter.
Examples:
• A small compressor-operated refrigerator with a rated power of approx. 50 W may have ten
times the power consumption (500 W) for three seconds after activation, since the electrical
motor starts.
• A light bulb rated power of approx. 60 W may have ten times the power consumption
(600 W) for one second after activation, since the low-impedance spiral-wound filament
heats up. Only as the temperature rises will the electrical impedance increase as well so that
the power consumption drops to rated output.
Due to the many different electrical consumers, it is not possible to provide a precise list
of where problems are to be expected.
For example, consumers with integrated electrical motor, capacitors in mains units,
devices with inductive load or light bulbs or heating radiators are problematic.
