How to Connect a Power Station to Your House (Safely)

By Hicham M. · Updated October 17, 2026

There are three safe ways to get power from a power station into your home: run cords to the appliances, have an electrician install a transfer switch or interlock with an inlet, or buy the maker’s own home panel. There is one unsafe way that people still try: plugging the station into a wall outlet. This guide covers all four, in that order.

This page explains the options so you can talk to an electrician. It doesn’t tell you how to wire anything.

1. Extension cords straight to the appliances

The simplest option needs no installation at all. Put the station where it can breathe, plug the fridge into it, and run a cord to a lamp and the Wi-Fi router. Everything on the AC outlets is still powered by the station’s own inverter, and nothing touches the house wiring.

The rules are the same ones OSHA gives for generators: use cords that are grounded (three-prong), check that they aren’t “damaged, cut or abraded”, and make sure they’re “appropriately rated in watts or amps for the intended use”. A thin lamp cord feeding a fridge is a fire risk.

Cords work for anything with a plug: a refrigerator, a chest freezer, a CPAP, a router or a TV. They don’t work for hardwired loads like a gas furnace or a well pump. Those need one of the options below.

2. A transfer switch or interlock, plus a power inlet

To feed house circuits, an electrician installs two things: a power inlet box on the outside wall (a weatherproof socket the station’s cord plugs into) and a device that keeps the house disconnected from the grid while it runs on backup. That second part is the whole point. The National Electrical Code’s Article 702, which covers optional standby systems, requires transfer equipment “designed and installed so as to prevent the inadvertent interconnection” of the two sources, as EC&M magazine quotes it. Volusia County, Florida, applies the same rule to residential manual transfer equipment, which “will require an interlock device”. Both of those sources cite older code editions (2005 and 2008), so your electrician works from the edition your area has adopted.

There are two common ways to do it.

Manual transfer switch vs interlock
	Manual transfer switch	Interlock kit
How it works	A small panel next to the main one. Each circuit wired into it has its own switch: utility or backup.	A plate on the main panel that lets either the main breaker or a backup breaker be on, never both.
What it can power	Only the circuits wired into it, picked in advance	Any circuit in the panel, one breaker at a time
Overload risk	Lower, since the choice is limited	You manage the load yourself by switching breakers off

Lake Country Power, an electric cooperative, describes the transfer switch this way: it “takes power from the generator and distributes it only to the branch circuits that were selected”. Purdue Extension’s interlock guide puts the interlock rule simply: “Only the main service breaker or the generator breaker can be on at the same time.” Both prevent the dangerous case described in section 4.

A station plugs into the inlet just like a generator would, through the right cord from one of its larger outlets. The station manuals take this seriously. EcoFlow’s DELTA Pro 3 manual says “A transfer switch is essential to safely isolate backup power from the grid power” and not to connect a station to a building “without a properly installed isolation switch”. Anker’s F3800 manual asks you to confirm the inlet box or transfer switch has its neutral and ground wires properly connected before feeding it from the 240 V ports. Both are reasons to have a licensed electrician do the job and test it.

3. The maker’s own home panel

Several brands sell hardware that connects their larger stations to a home. Here is what each maker’s own page says it does. All of them sit between your main panel and the circuits you back up. Most of the pages say a professional must install them; where a page is silent, plan on a licensed electrician anyway.

Manufacturer home integration hardware
Product	What the maker says	Works with
EcoFlow Smart Home Panel 2	12-circuit sub-panel, 20 ms automatic switchover, app control. EcoFlow says it “requires installation before use”; its install service sends a certified electrician.	EcoFlow DELTA Pro 3, EcoFlow DELTA Pro, DELTA Pro Ultra
Anker SOLIX Home Power Panel	Switches over automatically during outages. Its optional 12-circuit backup load center can only be installed indoors, according to Anker’s owner manual.	Anker SOLIX F3800 series
Anker SOLIX 10-circuit manual transfer switch	Sold with the F3800 Plus as a home backup kit; you switch circuits over by hand.	Anker SOLIX F3800 Plus
Jackery Smart Transfer Switch	Up to 12 circuits at 120 V or 6 at 240 V; switches within 20 ms with UPS mode on in the app, about 5 seconds without. Jackery says “Professional electricians must handle the installation.”	Jackery Explorer 5000 Plus (up to 2 units)
BLUETTI AT1	An automatic transfer and energy-management panel that switches the home to backup when needed. BLUETTI doesn’t list a circuit count on the page.	BLUETTI Apex 300 (up to 3 via Hub A1)
Goal Zero Yeti Home Integration Kit	A 4-circuit, 120 V manual transfer switch rated 1,875 W, plus a cable. Must be installed by a licensed electrician, and only with an indoor breaker panel.	Yeti models of 1,000 W and up (the page is inconsistent on the exact minimum)
Goal Zero Haven 10	A manual transfer switch for up to ten 120 V circuits. Goal Zero says it “must be professionally installed”.	Goal Zero Yeti PRO 4000

Product names, circuit counts and compatibility as listed on each maker’s US product page or manual (the Canadian page for the Anker kit) in October 2026. Check the current page before buying; compatibility lists change.

The automatic panels suit you if you want the house to switch over without anyone touching a breaker. A plain transfer switch works with any station that can supply the right outlet.

4. Never backfeed through a wall or dryer outlet

The shortcut is a cord with a male plug on both ends, one into the station and one into a wall outlet or a 240 V dryer outlet. The U.S. Consumer Product Safety Commission says these male-to-male cords are “often referred to as ‘suicide cords’” and warns that their exposed prongs can become energized.

When you do that, power flows backward from the outlet into the panel and, unless the main breaker is off, out to the street. Lake Country Power explains that it then reaches the transformer, “which then converts it back to thousand of volts”. A line worker restoring power can be electrocuted by a line they believe is dead. The Missouri Public Service Commission warns that backfed power can be “enough to kill a utility lineman making outage repairs a long way from your house.” OSHA’s generator fact sheet says attaching a source without a transfer switch “can energize wiring systems for great distances” and creates “a risk of electrocution for utility workers and others in the area”.

It’s also against the rules. Lake Country Power calls backfeeding “illegal in many localities” and says a utility may fine or disconnect a customer who does it. Building departments say the same: both Volusia County and Placerville, California, state that back-feeding household outlets “is not permitted”.

It’s risky inside the house too. A male plug on a live cord has exposed, energized prongs, and nothing stops someone from flipping the main breaker back on. A transfer switch or interlock exists to make that mistake impossible.

120 V or 240 V?

Most of what a station runs in an outage is 120 V. But some house loads are 240 V, including many well pumps. Lake Country Power notes that “some appliance outlets for electric ranges or electric dryers supply 240 volts”.

Of the 54 models in our database, 5 have 120/240 V split-phase output built in:

EcoFlow DELTA Pro 3: 4,000 W continuous, 8,000 W surge
Jackery Explorer 5000 Plus: 7,200 W continuous, 14,400 W surge
BLUETTI Apex 300: 3,840 W continuous, surge not published
Anker SOLIX F3800: 6,000 W continuous, 9,000 W surge
Anker SOLIX F3800 Plus: 6,000 W continuous, surge not published

One more, the Anker SOLIX F3000, reaches 240 V only when two units are paired through Anker’s Double Voltage Hub.

A 120 V-only station can still feed 120 V circuits through a transfer switch, as Goal Zero’s 120 V kits show. It can’t run 240 V loads at all. For a 240 V well pump, voltage is only the first hurdle: our planning figure for a 1/2 HP pump is 5,300 W to start. 3 of the 5 240 V models publish a surge rating at or above that, and 2 don’t publish a surge rating, so we can’t say.

Capacity matters as much as voltage. 24 of our 54 models accept extra batteries, which is how the big home-backup setups reach multi-day runtimes. The power station finder filters for 240 V, surge and battery size at once.

Permits and inspection

Adding an inlet, interlock or transfer switch is electrical work on your service, and most places want a permit. Arvada, Colorado, for example, says a portable generator setup “may require a Residential Electrical permit if you are adding an Interlock”, lets homeowners pull the permit only for work they do themselves, and lists rough and final electrical inspections. Placerville requires a permit application for generator transfer switches and says inlets and transfer equipment must be UL listed, with a sign near the inlet. Ask your local building department; the rules vary, and the inspection is a second check on the work.

Which option fits

For a fridge, CPAP, router and lights, cords are enough; size it with the outage sizing guide. For a furnace, well pump or a few hardwired circuits, get a transfer switch or interlock with an inlet, installed by a licensed electrician. For automatic whole-home backup, look at the maker panels above. Check whether the station can start what you plan to run with the runtime calculator, and compare costs against a fuel generator with the generator vs power station calculator.

Questions

Can I plug a power station into a wall outlet to power my house?

No. That’s backfeeding. It can energize utility lines and electrocute line workers, and building departments and utilities prohibit it in many places. Use cords to appliances, or have a licensed electrician install a transfer switch or interlock with an inlet.

Is an interlock as safe as a transfer switch?

Both stop the house from being connected to the grid and the backup at the same time when installed correctly. The difference is what they let you power: a transfer switch limits you to pre-selected circuits, an interlock opens the whole panel and leaves load management to you. Whether an interlock is accepted depends on your local code and inspector.

Do I need a 240 V power station?

Only if a load you must run is 240 V, like many well pumps. Most outage essentials are 120 V.
