7. OPERATION
Whichconsumersthatareoperatedwithmainsvoltage(230V/AC,50Hz)canbeconnected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briey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lamentheatsup.Onlyasthetemperatureriseswilltheelectri-
cal 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.

Ifseveralconsumersareconnected,thecombinedpowerintakeoftheconsumers(seeratingplatesonthe
consumer or in their operating instructions) must not exceed the output of the converter.
