Explain the purpose of backup power generators for residential applications.

What will be an ideal response?


Backup power generators are a promising market for residential applications. This is a relatively large market in developed countries where the number of electrical units in a household is substantial, ranging from computers to alarm clocks. Many higher-end housing developments now include an on-site generator for each individual house, running on different fuels such as diesel, propane, or natural gas. These systems are meant to protect the significant electronic investment in the house in the case of surges or blackouts.
