The average cost of a whole house generator is $7,000. But that doesn’t mean you can’t own one and save the extra money for home improvement. Here are some tips on how to save up for a generator:

  • Get an estimate from your local electric company to see what it costs per month.
  • Consider installing solar panels on your roof instead of shelling out rent or mortgage payments each month. Solar power doesn’t affect the entire house, just yourself and maybe a few other people in the household.
  • Install a rain-water collection system in your home. Rainwater is free, and you can use it to fill water tanks for other needs, like for hot water pumps.
  • Don’t drive or use the electricity from your air conditioner when it’s not being used. A storm could knock out power to your entire area, so use only what you need for short periods of time.
  • If you have solar panels, consider allowing them to generate power during the day when electricity usage is low. In the evening, tap into the batteries to start your generator.
  • If you want a new generator, consider buying one through online auction sites like eBay and Craigslist.
  • Buy a used unit if you are on a tight budget.
  • Hand in hand with buying a used unit is buying reconditioned parts from trustworthy companies that sell them.
  • Carry an extension cord with you when you’re away from home.
  • If you need to power your car or appliances at night, purchase a small portable generator capable of running one small appliance.
  • Buy a generator for $7,000 or less.
  • Don’t forget to replace the fuel filters on your generators, and if you have a gasoline powered generator, change the gas every 30 days.
  • Install a good quality battery backup system.
  • Place a portable generator on the highest possible shelf in your garage, and make sure all doors and windows are shut. [This is important for security reasons. You don’t want thieves to think you have money inside your home.]
  • Purchase a generator from a trustworthy company with an A+ Rating on their sites.
  • Always keep the fuel tank as full as possible.
  • Don’t use extension cords with generators. Use gas powered generators and plug directly into the wall outlet with the right adapter.
  • Always wear protective gear when working around a generator.
  • It’s best to stay away from portable generators that have 120V plugs on them, particularly if you don’t know how to work them.
  • Install a whole house generator as well as a battery backup system in your home for added safety measures. [This is important for security reasons. If you see that a wall is on fire, you don’t want to run out of electricity.]
  • If you decide to hire a professional electrician to install a whole house generator, don’t skimp on the quality of the installation. The installation should meet all safety guidelines set by the National Fire Protection Association.
  • If you really want to maximize your investment in your new generator, install solar panels and a rain water collection system that is hooked up to the battery bank. [This is important for security reasons. You don’t want the generator to be powering the whole house and it runs out of gas.]
  • Purchase a high quality generator that has a wattage exceeding your needs. [If you need a small appliance at a time, buy a generator that’s capable of powering more than one appliance.]
  • Avoid generators with low amp ratings.
  • Only use gas engines when you need to power up your whole house or portable appliances like air conditioners, heaters and refrigerators.
  • Have a manual on hand for the generator when you’re having problems.
  • When it comes to buying a whole house generator, find out what you need to do to automatically start one up. [Check with your local electric company before purchasing one.]
  • If you live in an area that has earthquakes, consider installing a portable generator that’s capable of running the refrigerator and freezer. [This is important for security reasons. You don’t want your food to go bad. You’ll have to keep the refrigerator and freezer plugged in to the portable generator.]
  • Install a battery tester in your home so you know when it’s time to replace your batteries.
  • If you want a backup for your generator, consider installing a propane or natural gas powered generator.
  • If you’re looking for cheaper alternatives, try solar flares and solar flares pens. [This is important for security reasons. Solar flares can make comets strike earth. Solar flares pens are used to start a fire. Solar flares can also cause huge amounts of damage to the earth and its weather.]
  • Be aware that if you purchase a whole house generator in your area, it might not be allowed by law as per fire safety standards.
  • Know the local laws, ordinances, fire and electrical safety codes pertaining to installation of a whole house generator. [Do your homework before installing one.] [This is important for security reasons. You don’t want to buy a unit and install it and get fined or arrested.]
  • If you plan on installing a whole house generator, contact your local electric company first.
  • If you plan on installing a whole house generator, have an electrician install it so you can receive proper training. [This is important for security reasons. You don’t want to mess around with live parts when working with electricity.]
  • Make sure the electrical panel in your home is compatible with the wattage of your unit.
  • Always have a generator as close as possible to your home. [This is important for security reasons. You don’t want thieves to know where you’re located.]
  • If it’s not prohibited by law, install your whole house generator outdoors in the shade. [This is important for security reasons. You don’t want to run out of power at a time when you really need it.]
  • When installing a whole house generator, consider hiring an electrician that specializes in this type of work. [This is important for security reasons. You don’t want to do something wrong and get shocked or burn yourself.]
  • Be very careful when it comes to working around existing electrical systems, such as outlets.
  • When purchasing a whole house generator, look for one with an automatic transfer switch capable of powering your appliances. [This is important for security reasons. You don’t want to run out of power.]
  • Buy a whole house generator that has a transfer switch and surge protector built into the unit. [This is important for security reasons.
