Best Solar Generators for Home Backup Power in 2026

Quick answer: The Anker SOLIX F3800 is the best solar generator for home backup, with 3,840Wh of capacity and 6,000W continuous output that can run central AC and a full circuit panel. The Jackery Explorer 2000 Plus is the strongest runner-up if you want to start smaller and expand later, scaling from 2,160Wh up to 12,960Wh as your budget and needs grow.

A solar generator is really a portable power station plus a set of solar panels, marketed for the use case of recharging without the grid or a fuel supply. Unlike a gas generator, it produces zero exhaust, runs silently, and can sit inside a closet or garage until you need it, which is exactly why so many homeowners are replacing dual-fuel generators with battery-based systems for anything short of multi-week outages. The four picks above cover the realistic range of home backup needs, from a single-appliance apartment setup to a full-panel whole-home system.

Anker SOLIX F3800: Best Overall for Whole-Home Backup

The Anker SOLIX F3800 is built for households that want to keep the refrigerator, well pump, furnace blower, and a few circuits of lighting running through a multi-day outage, not just a phone and a router. Its 6,000W continuous rating and 9,000W surge are high enough to start a 3-ton central air conditioner or a well pump directly, which is where smaller power stations typically fail even when their capacity looks sufficient on paper.

What sets it apart from a typical portable power station is the expansion path: it uses a distributed battery management architecture designed to pair with Anker's Home Power Panel, so you can wire it into your electrical panel and add a second unit later without replacing the first. For a full breakdown of specs, recharge times, and who should skip it, see our full Anker SOLIX F3800 review.

Standout strengths: highest continuous output in this class, true whole-panel integration, fast solar recharge at up to 2,400W.

Trade-offs: the price and physical footprint only make sense if you actually need whole-home coverage; for a single refrigerator and some lights, it is more capacity than most households will use.

Jackery Explorer 2000 Plus: Best Expandable Solar Generator

The Jackery Explorer 2000 Plus solves the biggest problem with sizing a solar generator for home backup: you rarely know on day one exactly how much capacity you will eventually want. Its base unit holds 2,160Wh, but it accepts up to five Battery Pack 2000 Plus add-ons, scaling to 12,960Wh without buying a second inverter or a separate unit to manage.

That makes it the right call for a household that wants to start with backup for the refrigerator, modem, and a few lamps this year, then add capacity for a sump pump or window AC unit next year, all on the same base station. See our Jackery Explorer 2000 Plus review for full expansion pricing and real-world recharge numbers.

Standout strengths: lowest cost-per-watt-hour path to whole-home-scale capacity, no need to commit to a large purchase up front, 3,000W continuous output covers most single-appliance loads.

Trade-offs: each expansion battery is a separate purchase, so the total cost of a fully expanded system can exceed a single large unit like the F3800.

Anker SOLIX C1000 Gen 2: Best Value for Essentials-Only Backup

Not every household needs whole-home coverage. If your outage plan is really "keep the fridge cold, keep the router up, and keep phones charged for a couple of days," the Anker SOLIX C1000 Gen 2 delivers that at a fraction of the cost of a whole-home system. Its 1,024Wh capacity and 2,000W continuous output are enough to run a full-size refrigerator for well over a day on a single charge, and its 58-minute AC recharge means you can top it back up quickly during a lull in the outage if you have a generator or a working outlet nearby.

Full specs and how it stacks up against the similarly priced Jackery Explorer 1000 v2 are in our Anker SOLIX C1000 Gen 2 review.

Standout strengths: fastest AC recharge in its price tier, genuinely portable at under 30 pounds, solid solar input for a mid-size unit.

Trade-offs: 2,000W will not start a well pump or central AC, so treat it as an essentials unit, not a whole-home replacement.

Anker SOLIX C300: Best for Apartments and Small-Space Backup

Renters and apartment dwellers often get overlooked in home-backup guides built around whole-house systems, but a compact unit solves the problem that actually matters to them: keeping a router, a CPAP machine, a phone, and a lamp running through a multi-hour outage without a balcony full of solar panels or a wired-in system. The Anker SOLIX C300 covers that use case at 288Wh and a size that fits in a closet shelf.

Standout strengths: smallest footprint on this list, still solar-rechargeable, low enough cost to buy as a second or backup unit alongside a larger station.

Trade-offs: 300W continuous output rules out anything with a compressor or motor, including most refrigerators, so pair it only with electronics and small appliances.

What Makes a Power Station a Solar Generator?

"Solar generator" is a marketing term, not a distinct product category. Every model on this list is a battery-based power station with an MPPT solar charge controller built in, which means it can accept panels directly without a separate charge controller the way a DIY off-grid battery bank would need. The real differences between models that matter for home backup are capacity (how long it runs your loads), continuous and surge output (what it can start and sustain), and solar input wattage (how fast the sun refills it during a multi-day outage when grid and generator recharging are not options).

Compared with a gas or propane generator, a solar generator has no fuel to store or stale out, produces no carbon monoxide, and can be used indoors, but it has a hard capacity ceiling. A gas generator can run indefinitely as long as fuel lasts; a solar generator is limited to its battery plus whatever your panels can pull in during daylight hours.

How to Size a Solar Generator for Your Home

Start by listing what you actually need to keep running, not everything in the house. Add up the running wattage of each device (printed on a label or in the manual), not just its plug rating, and separately note anything with a compressor or motor, since those need 2-3 times their running wattage to start.

• Phones, router, and lighting only: a 250-500Wh unit with 300-600W output, like the Anker SOLIX C300, covers a day or more.
• Add a refrigerator: plan for 1,000Wh or more and at least 1,500-2,000W continuous output, which is where the Anker SOLIX C1000 Gen 2 fits.
• Add a sump pump, window AC, or multiple large appliances: you need 2,000Wh-plus and 3,000W or higher output, the territory of the Jackery Explorer 2000 Plus.
• Central AC, a well pump, or whole-panel backup: only a 3,000W-plus continuous unit like the Anker SOLIX F3800 will start these loads reliably.

Our guide to using a power station for home backup during outages walks through wiring options, from simple extension cords to a manual transfer switch, once you have picked a unit.

Pairing Solar Panels With Your Generator

A solar generator without panels is just a battery that runs out during a multi-day outage. If you expect outages to last more than a day, budget for solar panels sized to at least match your unit's rated solar input, and check the panel's real-world output, which typically lands at 70-85 percent of its rated wattage in clear conditions. Our guide to the best solar panels for generators compares foldable, rigid, and portable options by watts-per-dollar and packability, which matters more than raw wattage if you also need to store the panels between outages.

Common Mistakes When Buying a Solar Generator for Home Backup

• Sizing by capacity alone. A large Wh rating means nothing if the continuous output is too low to start your refrigerator or AC compressor. Check both numbers.
• Ignoring surge rating. Motors and compressors need a short burst of 2-3x their running wattage to start. A unit that looks adequate on continuous output can still fail to start a fridge if its surge rating is too close to the continuous number.
• Assuming solar panels are included. Most solar generators are sold as the power station alone; panels are a separate purchase that can add several hundred dollars to the real cost.
• Buying based on outage frequency alone. If outages in your area are rare but long when they happen, prioritize capacity and expandability over a cheaper, smaller unit.
