Yes. A battery solar generator (a portable power station) is one of the few backup power options that fits an apartment. It burns no fuel, so it gives off no carbon monoxide and can run indoors. Charge it from a wall outlet, or from panels on a sunny balcony, then keep it ventilated and within its rated output.
Why a solar generator works where a gas generator cannot
A solar generator is a battery with an inverter and outlets, so it makes no exhaust. Jackery says its power stations do not burn fuel, give off fumes or produce carbon monoxide. That is the whole reason it suits an apartment.
A gas generator does not. The CPSC tells people to run one outside only, at least 20 feet from the home, and never inside a home, garage, basement, shed or on a porch. Opening windows does not make indoor use safe. Our solar generator vs gas generator guide compares the two in more detail.
How to charge a solar generator in an apartment
You have three ways to charge a solar generator without a roof or yard:
- Wall outlet. The fastest and most reliable. Keep the unit topped up before storm season and recharge it after each use.
- Panels on a balcony. A folding portable panel propped in direct sun can refill the battery during an outage. A unit plus a folding panel needs no wiring. Check that the panel’s watts and voltage sit within the station’s solar input limits.
- A panel behind a window. This works, but window glass absorbs and reflects part of the sunlight, so output drops. How much depends on the glass: heavily tinted windows cut it the most, Low-E coatings can also reduce it, and a window facing away from the sun gets less light to begin with. Expect a slower top-up than outdoors.
In the US, a south-facing balcony or window usually gets the most sun. Our guide to how to charge a solar generator lists wall, solar and car charging times for popular models.

Battery safety for a solar generator indoors
Lithium battery fires in apartments are a real concern for fire departments. After a fatal fire in a Queens basement apartment in June 2026, the FDNY urged people to charge lithium-ion devices outside where possible, not to charge overnight, and not to block exits. Its standing tips add: buy products certified by a recognized testing lab such as UL, keep charging off beds and couches, and use the maker’s own cord and adapter.
For a power station, look for certification to UL 2743, the US and Canadian standard for portable power packs. Its current edition, the third, is dated September 24, 2025. The standard’s scope covers packs for outdoor use, temporary outdoor use or indoor use only: indoor-only packs are meant to be stored and used indoors, never outdoors. Ask the seller for the listing if the box does not show it.
| Safety check | What to look for |
|---|---|
| Certification | UL 2743 listing, or another recognized lab’s mark |
| Placement | Hard, level floor with space around the vents; away from heaters and bedding |
| Temperature | Within the operating range in the manual |
| Load | Appliance watts under the unit’s rated output |
| Exits | Not in a hallway, doorway or the path to the stairs |
Jackery also advises leaving space for heat to escape, and its HomePower 3000 FAQ says that unit is not fully fireproof.
Lease and building rules for solar generators
Read your lease before you buy. A building can restrict battery equipment, items on a balcony railing or anything that blocks a fire escape. In New York City, apartment building owners must hand residents and staff the FDNY’s annual fire safety bulletin, which opens with lithium-ion battery tips. The tips are written for New York City, but they work as a checklist in any apartment.
Panels hung on a railing raise separate questions. If your goal is a smaller power bill rather than backup power, a plug-in balcony kit feeds the apartment’s wiring instead of a battery, and some states now allow it. It is a different product from a solar generator: it shuts off in a blackout. Our balcony solar guide lists those states, the size caps and what to check first.

What size solar generator fits an apartment
Apartment loads are usually modest: a router, phones, a laptop, LED lamps and perhaps a CPAP or a mini fridge. A unit of about 500 to 1,000 Wh covers that kind of load through a short outage. A full-size fridge for a whole day needs more capacity or daily solar recharging.
Weight also matters when you carry the unit up stairs or store it in a closet. See what a 1000Wh power station can run for appliance runtimes, and what size solar generator you need to add up your own loads. More models and brands are in the power stations section. For phones alone, a solar power bank is lighter, and Jackery Explorer models lists one brand’s range by capacity and weight.
Frequently asked questions
Is it safe to use a solar generator indoors?
A battery solar generator burns no fuel, so it gives off no carbon monoxide, and makers such as Jackery list them for indoor use. Give it space for airflow, keep it off bedding and away from heat, and stay within its rated output.
Can I charge a solar generator through a window?
Yes, but more slowly. Window glass absorbs and reflects part of the sunlight, so a panel behind glass makes less power than it would outside. Heavily tinted glass cuts output further, and Low-E coatings can too. A balcony or an open window ledge in direct sun works better.
Can my landlord ban a solar generator?
A lease can restrict battery equipment, panels on railings or anything left on a balcony, so read it first. New York City apartment owners must hand residents the FDNY's annual fire safety bulletin, which includes lithium-ion battery tips.
Can I run a gas generator on an apartment balcony?
No. The CPSC says to run a gas generator outside only, at least 20 feet from the home, and never on a porch or in a garage. A balcony attached to an apartment is too close to doors and windows.
What size solar generator does an apartment need?
For a router, phones, a laptop and LED lights through an outage, a unit of about 500 to 1,000 Wh is a reasonable starting point. Keeping a full-size fridge running for a day takes more, so add up your loads first.
