Emergency power generators briefly explained
Emergency generators and emergency power systems are available in various power classes and can therefore supply a single-family home, a fire station, a town hall, an emergency meeting point or even an entire hospital with the necessary electrical energy in the event of a blackout or brownout. Emergency power supplies with appropriately large diesel emergency generators are particularly important for public facilities. It is important that the power generator and consumer are matched to one another in terms of power size.
In a single-family home, the emergency generator usually only has to supply the heating, refrigerators, lights or cooking facilities in the event of a power failure. Since the heating control is a sensitive electrical device, the power generator must have aAVRhave.inverter generatorare often recommended for emergency power supply, but are only suitable for operating individual electrical devices and not for feeding into a house's power grid. The output of the generators usually ranges from 3000 watts to around 10 kW. We recommend using single-phase devices with 230 volts to avoid unbalanced loads and the associated voltage fluctuations. Many generators have additional sockets so that individual consumers can also be connected. A combustion engine with diesel fuel is often used as the drive, but emergency generators with petrol or gas are also available. Suitable devices are available from Champion (Warrior), Yorking, Pramac, SDMO Kohler or Endress and Mosa.
For a fire station, town hall, emergency meeting point or hospital, powerfulemergency generators or emergency power systems in a power range from 10 kVA to 500 kVAcontinuous power The power supply is connected via specialfeed-in socketsor fixed wiring on a terminal block. The running time with one tank filling is 10 to 30 hours for most generators. Due to the performance and the noise requirements, generators with 1500 rpm and a soundproof housing are mainly used.
Which emergency generator for a single-family home?
For a single-family home, an emergency generator with an output of between 5,000 and 10,000 watts (5-10 kW) is generally recommended[1]. When making your selection, you should consider the following points:
power requirements
Determine the power requirements of the most important devices you want to operate in an emergency.
A 5-10 kW unit is sufficient for most single-family homes.
fuel
Gasoline engines are cheaper to buy, but are louder and less efficient.
Diesel engines are more durable and efficient, but more expensive.
Gas generators are similar to a petrol generator and are worthwhile when gas is available, e.g. in an LPG tank.
functions
Automatic start in case of power failure (ATS emergency power system)
Inverter technology or AVR for sensitive electronics
Sufficient connections for your devices

Additional considerations
Pay attention to noise level and exhaust emissions, especially when installed in or near the house.
Permit not usually required, but check local regulations.
As a tenant, obtain permission from the landlord.
Choose a unit that meets your specific needs and pay attention to quality and reliability so that you are well prepared in an emergency. Contact us, we will be happy to advise you.
