A transfer switch is a house product. A solar generator is a cord product.
People type “transfer switch” next to a solar generator because they want the wall outlets to stay live. That is a real wish. It is also a different purchase from the battery on the kitchen floor. This page sorts three legal paths and then stops. It will not sell you a weekend at the breaker panel.
Updated September 2, 2026
The short version
- Cords you can see are the default for a ~2 kWh 120-volt solar generator.
- An inlet box with an interlock is licensed work that keeps chosen wall circuits live without backfeeding.
- An automatic transfer switch belongs to a standby generator, not a Jackery.
- No DIY steps.
- No invented switch prices.
- Points at the whole-house hub and existing SKUs.
Read this after the solar-generators hub. The night map (fridge, internet, what fails) is stations for home backup. The pad-and-permit decision is the whole-house generators hub. Nothing here is electrical, permitting, or fire-code advice. Hire the person who will pull the permit.
The one rule with no warm version
Never backfeed a dryer outlet. No double-ended cord. No “just for tonight.” A backfeed can energize the downed line a lineworker is about to touch, and it can burn the service. It is illegal essentially everywhere. The three paths below are the boring ones that keep that from happening.
Path 1: cords you can see
Station on the kitchen floor or in the hallway. Fridge, network, lamps on rated extension cords you can see the whole length of. No electrician. No inlet. No paperwork. This is the default for the class we feature, and a corded fridge is a completely successful outage. There is no trophy for complexity.
The machines this path is for: the BLUETTI AC200L (2,048 Wh, 2,400 W, 62.4 lb, $847 that day, $52 off $899), the Anker SOLIX C2000 Gen 2 (2,048 Wh, 2,400 W, 4,000 W peak printed, 41.7 lb, $949.99 that day), and the Jackery Explorer 2000 Plus (2,042.8 Wh, 3,000 W, 61.5 lb, $2,199 listed). Prices checked September 2, 2026. Jackery hop stays brand-root; the standalone Explorer 2000 Plus was not available that day, kits still listed on that same PDP. Full notes stay on those URLs. This page will not clone them.
Keep the list short. Close the refrigerator door. Skip the space heater. The fridge math is fridge runtime. Indoor-safe is the quiet luxury of a battery: no exhaust, no engine. A gasoline generator does not borrow this paragraph. Combustion stays outside, at code distances, forever.
Path 2: inlet box and interlock
An electrician mounts a wall inlet, then a sliding plate (an interlock) in the panel so the utility main and the inlet cannot both feed the bus. The wall outlets you chose stay live. You still walk outside, or to the inlet, and plug the cord in. It is a manual transfer, not an automatic one.
This is licensed work in almost every US jurisdiction. This page will not name breaker sizes, torque specs, or which knock-out to use. Owners keep saying they wanted the walls live so nobody tripped on a hallway cord. Spec sheets do not install that for you. Budget the visit before you budget a second battery. A legal interconnect on a 120-volt core can cost as much as the core. That does not make the core a bad machine. It makes the install the product.
Still 120 volts on the three featured stations. Extra batteries add watt-hours. They never add the missing hot leg. A well, a dryer, a split-phase air handler still wants the Anker SOLIX F3800 (3,840 Wh, 6,000 W, 9,000 W surge, 120/240 V, 132.3 lb, $2,199.98 on August 26, 2026) or a pad generator. The F3800’s whole argument is that split-phase house hook, and hooking it up is still an electrician. Stay on Anker SOLIX, not Anker.com retail. Shop: Anker SOLIX.
We do not have a dated manufacturer street price for an inlet kit or an interlock plate that we trust enough to print, so those cells stay blank. The electrician’s quote the week you buy is the number. Do not order a kit from a video and call it a plan.
Path 3: automatic transfer switch
An automatic transfer switch senses the outage, starts the standby generator, and flips the house. Nobody wades out at 2 a.m. with a cord. That is the product you are imagining when you type “transfer switch” next to whole-house backup. It is not an accessory you add to a 2 kWh solar generator. The inverter, the fuel, the pad, and the switch are one project.
We do not sell named standby machines, and we will not invent a Generac hop or a switch SKU. The thinking lives in the whole-house generators hub: class, all-in cost (the switch is a line on that bill, not a cart on this site), standby vs portable, and the buying guide. Fuel that survives the same storm, a pad that passes inspection, someone who will exercise the engine. Those are the ATS conversation. A Jackery is not invited.
If the honest list is fridge and router, put the tape measure down. Path 1 is cheaper and quieter and already legal. If the honest list is furnace, well, and days, skip this solar-generator URL and go to the pad.

Stay on cords if
- The must-list is 120-volt and you can reach it with a rated cord.
- Outages run hours to a day, and a corded fridge counts as success.
- You would rather not open the panel.
This page is the wrong aisle if
- You wanted a how-to for installing an interlock. That is an electrician, not an article.
- The house has to run itself: whole-house generators.
- A 240-volt load votes and you still want a battery: F3800.
What we’re not claiming
This is not a wiring diagram, a permit checklist, or a price for a switch. Nobody here pulled a panel after a storm and timed the interlock. The three paths are the documented legal shapes plus what owners keep saying about hallway cords. Featured shops on the battery side: BLUETTI, Anker SOLIX, Jackery. No generator hop.

If you buy a featured station after a link here, we may earn a small commission. Your price does not change. We do not earn on a transfer switch or a standby generator. Disclosure.
