"I couldn?t be happier with the work River Sun Solutions did installing my off-grid solar system with generator backup. From the very beginning, their service was absolutely perfect ? professional, responsive, and extremely knowledgeable. The quality of their work really stands out. The installation was done with great attention to detail, and everything was completed to a very high standard. It?s clear they take pride in what they do. Most importantly, my system has been operating for over a year now without a single issue. That kind of reliability speaks volumes about the quality of their design and installation. If you?re considering an off-grid solar setup, I highly recommend River Sun Solutions. They deliver exactly what they promise ? high-quality work and exceptional service."

Generator Install FAQs, answered by experts

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.
