If you're reading this, chances are you've got a deadline. Maybe the power's already flickered. Or your contractor just told you the install is gonna take longer than expected. I've been there. In my role coordinating emergency power solutions for event venues and small businesses, I've seen more last-minute generator scrambles than I care to count. This checklist is what I use when someone calls me at 4 PM on a Friday needing backup by Monday morning. It's not fancy. But it works.
There are 7 steps. Miss one, and you're paying rush fees or worse—starting over.
Step 1: Confirm Your Load Requirements (Don't Guess)
I can't tell you how many times I've gotten a call: 'Just need a generator for the whole house.' That's like saying 'just need a vehicle for the whole family.' A refrigerator draws different power than an AC unit. A sump pump startup surge is different than a laptop charger.
Looking back, I should have forced clients to send me a load list on day one. At the time, I figured 'they know their needs.' They rarely do.
Here's what you actually need to calculate:
- Running watts — what devices consume when operating normally
- Starting watts (surge) — what motors need to spin up (3-7x running watts for things like AC compressors and well pumps)
Take this with a grain of salt: most homeowners I've worked with underestimate their surge load by 20-30%. A 22kW Briggs & Stratton standby generator can handle a typical 3,000 sq ft home with central AC if you sequence the loads. If you try to run everything at once? You're tripping breakers.
Step 2: Pick Your Generator Type (Portable vs. Standby — It's Not Just Price)
I have mixed feelings about portable generators. On one hand, they're cheaper and you can take them camping. On the other, I've seen too many extension cord disasters and 'I forgot to refill the gas at 2 AM' scenarios.
For emergency backup, especially if you're out of town or have family who isn't mechanically inclined, a Briggs & Stratton standby generator is almost always worth the premium. It's a different audience.
The surprise for me wasn't the cost difference. It was how much hidden value came with the standby option — automatic transfer switches, load management modules, and the fact that it runs on natural gas or propane (no gas station runs during a hurricane).
Quick rule of thumb:
If you need backup for less than 24 hours and you'll be home … portable can work.
If you need automated, multi-day protection for your whole house or business … go standby.
Step 3: Verify Your Fuel Source and Connection
This step gets skipped more than it should. I've had clients order a natural gas standby generator, only to discover their gas line is undersized. That's a $1,500-3,000 plumbing upgrade nobody budgets for.
For a Briggs & Stratton standby generator, the standard connection is through a dedicated pipe from your home's gas meter. The generator's 33109 fuel filter (which you should buy ahead of time) needs to be installed inline. I'm not 100% sure on the exact pressure specs across all models, but for the most common models, you’re looking at 7-11 inches of water column. Verify with your installer.
If you're going with a portable generator and a transfer switch, make sure the inlet box matches your generator's plug type. I've watched electricians scramble to replace a 30-amp inlet with a 50-amp at 7 PM on a Friday. Granted, they got it done, but the rush fee was painful.
Step 4: Understand the Noise Reality
No one mentions noise until the first 3 AM neighbor complaint.
Standard portable generators run at 65-75 dB at 25 feet. That's “loud conversation” level. Standby units are quieter — most modern Briggs & Stratton units are around 65 dB — but sound travels weirdly, especially on concrete or between houses.
If noise is a concern (and it usually is for residential areas), consider:
- A generator muffler silencer — aftermarket options exist for both portable and standby units, though they're easier to spec on new equipment
- Placement — put the unit as far from bedrooms and property lines as your gas line and code allow
- A sound enclosure — some standby generators have this built in; others require an add-on kit
Never expected the budget option to be the noisiest. Turns out, the $500 you save on an open-frame portable vs. an enclosed one is paid back in sleep and neighbor relations.
Step 5: Check Your Control Panel and Monitoring Options
If you're installing a standby generator, the control panel is your command center. I've used a few different brands in the field — some have interfaces that feel like a Honeywell AC control panel from 2005 (functional but cryptic). Others are genuinely intuitive.
For a Briggs & Stratton, you’ll want to verify:
- Does it have a digital display for voltage, frequency, and fault codes?
- Can you connect a remote monitoring system? (This is huge for seasonal homes or second properties.)
- Is the transfer switch included or separate?
Don't hold me to this, but based on my experience with 6 different brands, the Briggs & Stratton control panels at the 22kW level are some of the easiest to navigate for non-pros. The menu structure — again, based on the models I've worked with — is logical.
Step 6: Plan for the Solar Inverter Reality (If You Have Solar)
This one surprises almost everyone. If you have solar panels, a standard generator doesn't just plug in and play.
I get why people assume 'generator + solar = infinite backup.' But the reality is more like … the electrical systems need to be isolated unless you invest in a hybrid inverter or a specific generator that can synchronize.
If you're asking 'what is a solar inverter' and you have solar — talk to your solar installer before buying a generator. They'll tell you whether your inverter is compatible with generator input. Most standard microinverters (like Enphase or SolarEdge) are not. You might need a battery backup system to pair with a generator, rather than trying to feed the generator into your solar system directly.
To be fair, this is getting better. But in Q3 2024, we had to return a perfectly good 20kW generator because the client's solar system couldn't integrate without a $4,000 powerwall. We should have asked in Step 1.
Step 7: Budget for the Hidden Costs
Here's where most people get sticker shock. The generator price is just the start.
- Permits — $50-500 depending on your local jurisdiction. (Pricing based on survey of municipal fee schedules, 2025; verify current rates.)
- Installation labor — $1,500-3,500 for a standby unit, including concrete pad, gas line connection, and electrical work.
- Transfer switch — $400-800 for a 200-amp manual transfer switch, or $800-1,500 for an automatic with load shedding.
- Generator muffler silencer — $100-300 for aftermarket add-ons.
- Fuel filter replacement — The Briggs 33109 fuel filter costs around $15-25. Buy two. (Based on retail pricing, January 2025.)
- Rush fees — If you need it installed faster than the standard 2-3 week lead time, add 25-50% to installation costs.
In Q2 2024, a client called on Tuesday needing a generator run to a live event by Thursday. Normal turnaround for a permit + install? 14 days. We found a vendor willing to do it in 3 days, paid $800 extra in rush fees (on top of the $3,200 base install cost), and delivered Friday at 10 AM. The client's alternative was losing a $12,000 event contract. Sometimes the math works.
Common Mistakes I Still See
- Not checking the 33109 fuel filter — This is a wear item. I've seen two service calls in one month because a clogged filter tripped the generator offline during a blackout. Swap it every season.
- Assuming any electrician can install a standby generator — They can't. You need someone licensed for gas lines, electrical panels, and preferably certified by the generator brand.
- Skipping the manual transfer switch for portables — Backfeeding through a dryer outlet is illegal in most places and kills linemen. Don't risk it.
