Backup generators and emergency power supply

In short: A backup generator temporarily supplies power to important devices during a power outage. The choice between petrol, diesel, or battery-based solutions depends on duration of use and location.

In more detail: For private households, smaller, portable units are often sufficient, while larger systems can power entire houses.

In detail

• Generator types: Combustion generators provide a lot of power over a long time, while battery-based systems are quieter and emission-free.
• Calculating power needs: The sum of the wattage of all devices to be powered determines the required generator size.
• Safety distance: Combustion generators must never be operated in enclosed spaces due to carbon monoxide risk.
• Island operation: A backup generator runs separately from the public grid to prevent backfeeding and endangering technicians.
• Solar-based solutions: Power stations with solar panels offer a quiet, emission-free alternative for shorter outages.
• Maintenance: Regular test runs ensure the device actually works in an emergency.
• Prioritisation: In an emergency, essential devices such as the fridge or medical equipment should be connected first (stromausfall-vorbereiten, balkonkraftwerk).
