The answer to 'difference between generator installation' is that there are two main types of generator installations: portable and permanent. Portable generators are smaller, more affordable units that can be moved around and used for temporary power needs, while permanent generators are larger, fixed installations that provide backup power to an entire home or building.
Portable generators are typically less expensive to purchase and install, but they require manual operation and refueling. Permanent generators are more expensive upfront, but they start automatically when the power goes out and can run for extended periods without needing to be refueled. Permanent generators also integrate with the home's electrical system, providing a seamless transition to backup power.
