No property file says who has one in the garage, so marketing is guesswork.

Portable to standby upgrade leads from owners who are tired of extension cords.
Owners who own a portable already believe in backup power. They've also pulled it out in the rain, run cords through a cracked window, and refilled it at midnight. Spur finds likely upgraders and mails an honest comparison with a free sizing and a straight answer on cost.

AI draft for Curt M. · 1312 Algonquin Rd
Hi Curt,
We put an interlock kit on your panel back in 2020, so you've done the right thing for running a portable safely. You also know the routine: wheel it out, keep it away from the house, connect the cord, and keep the gas topped up, usually in bad weather.
If you've ever wondered what it would take to stop doing all that, a standby unit starts by itself within seconds and runs on natural gas, which your street already has. Since we already know your panel, the upgrade may be simpler than you'd think.
Scan the code on this card, and we'll size it for free and give you one written price.

How to market the portable to standby upgrade
A portable owner has already bought into the idea of backup power, which removes the hardest part of the sale. What's left is the difference between the two: a portable has to be stored, maintained, started, placed safely outside, fueled, and connected, often in bad weather. It also usually runs just a few circuits. A standby generator takes care of all that automatically, at a much higher price. The upgrade is really about convenience, coverage, and peace of mind.
Finding these owners takes some creativity, because no property record lists portable generators. Your own records are the best place to start: portable sales, interlock kit or manual transfer switch installs, and repair calls. Beyond that, target higher-value homes in outage-prone areas, and let the headline do the qualifying. An owner who has hauled a generator out in the rain will recognize themselves immediately.
Handle safety with respect. According to the U.S. Consumer Product Safety Commission, carbon monoxide from portable generators kills more than 70 people a year, and most at-home deaths involve a unit run in an enclosed or partly enclosed area. Backfeeding a home through a dryer outlet also endangers utility workers. These facts are serious, and it's fine to state them plainly once on a website or in a letter. Don't turn them into a scare headline on a postcard.
Explain the price jump honestly. A portable can cost under $1,000 while an installed standby system often runs $10,000 to $20,000, depending on size, fuel, and site. Say so. Then explain what's in that price: the unit, the transfer switch, the pad, the gas work, the permit, and the inspection. Financing can help, but only mention it if you actually offer it, and state any terms clearly and accurately.
Address the sizing question. Many upgraders don't need a whole-house system. A smaller unit with load management may cover the essentials for much less, and it often gets you to a yes. A transfer switch from a previous interlock project won't usually carry over, but the panel knowledge and electrician access can help. Explaining these options shows you're not just pushing the largest machine.
Time your follow-ups. Portable owners tend to reconsider right after they've used it. If an outage hits your area, a second card a week or two later will arrive when they still remember the extension cords. Offer them a fair trade-in or a plan for the old unit if you can, since many are reluctant to let go of equipment they've paid for. Plenty of owners keep it for the camper or the shed.

FAQ
Portable to standby questions
How do I find owners who have a portable generator?
Property records don't show them. Start with your past portable sales, interlock installs, and service calls, then target higher-value homes in outage-prone areas with a headline they'll recognize.
Should I mention carbon monoxide in my mail?
Mention it factually in a letter or on your website. CPSC reports over 70 deaths a year from portable generator CO. Don't turn it into a scare headline.
How do I explain the price difference?
State it plainly, then list what's included: unit, transfer switch, pad, gas work, permit, and inspection. Offer a smaller essentials-only option as well.
Can an existing interlock kit be reused?
Usually not as the standby transfer switch, but an electrician's familiarity with the panel can simplify the job. Confirm it at the sizing.
When should I follow up?
Soon after a local outage, when the memory of running the portable is still fresh, and again before the next season.
