AI tools for backup power

The advisor is useful for the part of the process where you're outnumbered: the sales conversation. Walking in with an independent wattage estimate and a cost range anchored to published data (a $5,090 national average installed, $1,500–$5,000 labor, about $1,200 transfer switch labor) changes the discussion.

It cannot see your electrical panel, your gas meter capacity, your lot's setbacks or your local code. Those four things routinely change the answer. Treat the output as a hypothesis for your installer to confirm or correct in writing.

It will also not make safety judgments for you. If you're weighing a portable, the fixed constraints stay fixed: outdoors only, at least 20 feet from windows, doors and attached garages, and CO alarms with battery backup on every level of the home.

Use it before you get quotes, not after. Its main value is preventing the two-size-classes-too-big outcome, and by the time you have a signed contract that's already happened.

How to choose

Feed it real nameplate numbers

Pull the wattage off your furnace, well pump and water heater data plates. Generic assumptions in, generic answer out.

Run it before the first sales visit

An independent estimate is only leverage if you have it before someone hands you a proposal.

Ask your installer to reconcile any difference

If their recommendation is much larger, make them show which load justifies it.

Don't use it for transfer switch design

Switch amperage, panel work and clearances are licensed-professional territory and get inspected.

Never use AI output to justify a shortcut on placement

The 20-foot outdoor rule and the CO alarm requirement don't flex for a clever configuration.
