What You're Losing Every Outage
Right now, it's limited to one cord, one circuit, one window cracked open. One connection changes everything.
1 appliance. 1 cord. Window cracked open in a storm.
All your essentials. One cord. Every window closed.
Unlock Your Investment
Without a panel connection, you're running one cord to one thing while the food spoils, the sump pump stops, and the family sits in the dark. One connection changes all of that.
Your essentials stay on. No $15,000 standby required.

What Can You Power?
Select your size. Tap what you want on. See if it fits.
All of this through your panel, no extension cords, no open windows.
Get Your Exact PriceYou can, but you're limited to one or two things at a time, you have to crack a window open (even in a storm), and it's a code violation that can void your homeowner's insurance. One panel connection lets your generator power your essentials, fridge, lights, WiFi, well pump, sump pump, and more, all at once, without extension cords and no trip hazards.
Our typical price is $1,197–$1,497, all-in, that's the cost to connect your existing generator to your panel. It covers the inlet hardware, permit, county inspection, generator cord, and a full walkthrough. Other electricians charge $800–$1,400 for the inlet alone, no permit, no cord, no inspection, no guarantee. For comparison, a whole-home standby generator starts at $15,000 installed. We connect what you already own for a fraction of that.
No. A whole-home standby generator is a permanent unit that runs on natural gas, and costs $15,000+ installed. This works with the portable generator you already own. We connect it to your breaker panel so it can power your essentials at a fraction of the cost, in one day.

Yes. Every install includes a safety interlock that physically prevents power from flowing back to the utility lines, protecting your home and the lineworkers restoring power. Licensed, insured, permitted, and inspected on every single job. A third-party county inspector verifies every install meets code.
