Just a few years ago, the thought of owning an emergency standby generator seemed somewhat silly and totally unnecessary. But with an aging power grid, living without electricity is all too common. Many homeowners simply cannot afford to ride out another power outage. Instead, they are installing home standby generators in record numbers to protect their families and investments. And, shopping for a standby generator online  can help avoid the shortages and high prices of trying to purchase ANY kind of generator when a weather event makes even portable generators hard to find and costly.
Engine Instead of Motor. Air conditioners run off electric motors, which obviously won't work during an outage. Home standby generators have engines instead. The systems can be connected to your natural gas line or liquid propane tank and generate electricity as long as fuel is supplied.
Automatic Transfer Switches. Instead of using a thermostat, standby generators use an automatic transfer switch to monitor your utility power. When it goes out, the automatic transfer switch turns on the generator - whether you're home or not - and automatically shuts it off when power is restored. Unlike portable generators, home standby generators operate automatically with no human intervention.
Whole house generators are the ideal solution because they do power the whole house. Unfortunately, they aren’t cheap. For example, the smallest whole house generator - a 25-kilowatt liquid-cooled generator - starts at around $7,500 for just the generator. The transfer switch isn't even included.
If you have the financial resources to power your whole house, go for it. Use the buyer's guide at www.electricgeneratorsdirect.com  to help find the perfect whole house generator for your needs.
If 16 circuits just aren't enough, you can install a "smart circuit" generator instead. These new generators won't power your entire house, but they'll maximize the amount of electricity produced by your generator.
