For a refrigerator + CPAP backup, I’d size around 2,000 Wh of LiFePO₄ battery capacity and at least 2,000–2,400 W of pure-sine AC output. That gives you enough reserve for compressor startup and several hours to a day or more of essential loads, depending heavily on the refrigerator and CPAP settings.

| System | Battery | AC output | Solar input | Why consider it |
|---|---|---|---|---|
| EcoFlow DELTA 2 Max | 2,048 Wh | 2,400 W | 1,000 W | Excellent balance; expandable to 6 kWh |
| BLUETTI AC200L | 2,048 Wh |
The AC200L is particularly interesting for your use case: BLUETTI specifies 2,048 Wh LiFePO₄, 2,400 W continuous output, 4,800 W surge, 1,200 W maximum solar input, a 20 ms UPS function, pass-through charging, and a five-year warranty.
BLUETTI AC200L + approximately 800–1,000 W of portable solar panels.
For example:
BLUETTI specifically lists four PV200 panels as a recommended configuration for the AC200L and estimates roughly 3 hours under favorable solar conditions. The AC200L accepts up to 1,200 W of solar, so an 800 W array leaves some headroom without requiring an enormous collection of panels.
A 2,000-Wh battery with only one 200-W panel sounds attractive because it's portable, but 200 W is not much solar for a refrigerator backup system. Real-world panel output varies with sun angle, clouds, temperature, shading, etc.
For an outage lasting multiple days, the important question isn't merely "How long will the battery run?" but:
Can I put enough energy back into the battery every sunny day to keep the refrigerator running overnight?
That's why I'd rather have 800–1,000 W of panels with a ~2-kWh battery than a 2-kWh battery paired with a single 200-W panel.
The DELTA 2 Max is also an excellent fit. It has 2,048 Wh, 2,400 W AC output, 1,000 W solar input, LiFePO₄ cells rated for 3,000+ cycles, and can be expanded to 6,144 Wh. EcoFlow says it can keep a refrigerator running for up to 14 hours under its specified test conditions.
EcoFlow currently offers configurations with two 220-W panels (440 W) and four 220-W panels (880 W); its published figures put the four-panel configuration around three hours for a full recharge under favorable conditions.
So if you value lighter weight, app/software, and portability, I'd look hard at the DELTA 2 Max.
If your CPAP uses a heated humidifier and heated hose, its consumption can be dramatically higher than the CPAP blower alone. For maximum runtime during an outage, you can often disable the heated humidifier/hose—but follow your CPAP manufacturer's instructions.
A rough illustration:
That's before inverter losses and other devices. A 2,048-Wh battery therefore isn't necessarily a two-day solution. Refrigerator compressors cycle, though, so actual consumption can be considerably different from this simplified calculation.
For a dedicated emergency setup:
BLUETTI AC200L + 800–1,000 W portable solar array is the combination I'd investigate first. Its 1,200-W solar input and 2,400-W inverter are well matched to this job.
For a more portable system:
EcoFlow DELTA 2 Max + 2–4 × 220-W panels is compelling.
For maximum inverter/surge headroom:
Jackery Explorer 2000 Plus + up to 1,400 W solar is worth considering; Jackery specifies 2,042.8 Wh, LiFePO₄, 3,000 W AC output and 1,400 W maximum solar input.
If you tell me your refrigerator's model number and your CPAP model (e.g., ResMed AirSense 10/11), I can calculate an estimated 12-, 24-, 48-, and 72-hour runtime and determine exactly how many watts of solar panels I'd pair with it.

An all-in-one portable power station with a capacity of at least 1,500 to 2,000 watt-hours (Wh) and 400W to 600W of compatible solar panels is required to reliably run a standard household refrigerator and a CPAP machine during a power outage.
Running a modern refrigerator (approx. 100–200W running, higher surge wattage) plus a CPAP machine (approx. 30–60W without a heated humidifier, or up to 100W+ with heated humidification) means your setup needs to pull roughly 1.5 to 2.5 kilowatt-hours (kWh) per day.
EcoFlow DELTA 2 Max : Features a 2,048Wh LiFePO4 battery and a 2,400W output, easily expandable. It can run a fridge and CPAP for an extended period and recharges rapidly via solar.
Bluetti AC200L : Offers a 2,048Wh capacity with a steady 2,400W AC output and strong solar input capabilities, making it reliable for heavy daily cycles and medical gear.
Anker SOLIX C1000 : A slightly more compact choice with a 1,056Wh capacity (expandable) that handles CPAP machines for multiple nights and charges exceptionally fast, though you must monitor total load if running a large fridge simultaneously.

If you can share the exact wattage or model of your refrigerator and whether you plan to use the heated humidifier on your CPAP , I can give you a more precise runtime estimate and panel size recommendation.
For keeping both your refrigerator and CPAP machine running during a power outage, I’d look for a portable power station with solar panels, rather than a small camping power bank. The key is having enough battery capacity to run both overnight and enough solar input to recharge during the day.
My recommendation is to prioritize three things:
These are the three setups I’d compare first, based on battery size, power output, solar charging, and cost.
About 2,074Wh battery capacity
A strong middle ground for a refrigerator, CPAP, phones, and lights. The 400W solar setup is useful for replenishing power during a sunny day. A good fit for people who want a compact, self-contained emergency kit.
Budget guide: roughly $1,000–$1,400 for a suitable bundle, depending on the seller and included panels.
About 3,000Wh battery capacity
Extra stored energy gives you more breathing room when the refrigerator runs frequently or solar conditions are poor. Look for a bundle with approximately 400W of solar panels included. This is the option I’d lean toward for a day or two of backup without relying entirely on sunshine.
Budget guide: roughly $1,400–$2,200, depending on the bundle.
1,024Wh battery capacity · 1,800W continuous output
A more affordable starting point if outages are usually short. It has enough output for many household refrigerators and CPAP machines, but its smaller battery means you’ll have less reserve for running both together over an extended outage.
Budget guide: approximately $600–$800 with a basic solar panel, subject to current pricing.
These are approximate shopping budgets, not guaranteed current checkout prices. Compare the exact battery capacity and solar-panel wattage included before ordering.
A refrigerator and a CPAP use energy very differently. Your refrigerator may consume several hundred to over 1,000Wh per day, depending on its size, age, room temperature, and efficiency. A CPAP can use relatively little power without heated humidification, but considerably more with heating enabled.
| Setup size | Best use |
|---|---|
| 1kWh + 200W solar | Short outages; limited combined runtime |
| 2kWh + 400W solar | Best starting point for essential appliances |
| 3kWh + 400–600W solar | Better reserve for extended outages |
| 4kWh or more + 600W+ solar | More resilience through multiday outages |
These are planning categories, not guaranteed runtime estimates. Actual performance depends on your appliances and available sunlight.
For your situation, I’d aim for 400W of portable solar panels with a 2–3kWh power station. That gives you a reasonable balance between stored energy and the ability to recharge during daylight.
A few things to check before buying:
I can recommend a more precise size if you tell me two things.
1. What kind of refrigerator do you have?
Full-size kitchen refrigerator
Large refrigerator with freezer or side-by-side
Mini fridge or compact refrigerator
2. How long do you want backup power to last?
One night
1–2 days
2–3 days
4 days or longer
3. Does your CPAP use a heated humidifier?
Yes
No
Not sure
4. What is your approximate budget for the station and panels together?
Under $700
$700–$1,000
$1,000–$1,500
$1,500 or more
[Find my best setup]
One important note: because your CPAP is a medical necessity, I’d size the system with a reserve rather than relying on ideal solar conditions. Keep a separate backup plan for the CPAP in case the battery runs down or several cloudy days prevent recharging.

EcoFlow DELTA Pro 3 is the most capable option of these for a serious outage kit: 4,096 Wh, 4,000 W AC output, 120/240 V, and expandable capacity. It can accept substantial solar input, which matters if an outage lasts several days.
EcoFlow DELTA 3 Ultra Plus is interesting if you want something less expensive and considerably easier to move. The current listing shows 3,072 Wh, 3–11 kWh expandable capacity, and smart output prioritization.
Jackery HomePower 2000 Plus v2 is a good middle-ground option: about 2,048 Wh and 2,400 W, with expansion to 12 kWh. The current bundle I found includes a 200 W panel.
Anker SOLIX F3800 moves into serious home-backup territory: 3,840 Wh and 6,000 W, with native 120/240-V capability. It's substantially heavier, though—about 132 lb.
If you're trying to cover only refrigerator + CPAP + modem/router + a few lights/phones, I wouldn't automatically spend $4,000–$5,000 on a whole-home system.
A ~2–3 kWh station + 400–800 W of portable solar panels is a sensible target.
Why? A refrigerator's compressor cycles rather than running continuously, while a CPAP is comparatively tiny. One independent test found roughly 30 hours of refrigerator runtime from a ~2 kWh station under its test conditions, while a 4 kWh DELTA Pro 3 lasted substantially longer. Actual refrigerator runtime varies dramatically with refrigerator efficiency, room temperature, and how often the door is opened.
For multi-day blackouts, solar becomes the important part. A larger battery doesn't help indefinitely if you can't replenish it. I'd rather have a 2–3 kWh battery with 600–800+ W of foldable panels than a huge battery with only a small 200-W panel.
If your CPAP supports DC operation, that's worth investigating. Running it directly from an appropriate DC output can avoid the power loss associated with converting battery DC → AC → CPAP power supply. And if you use a humidifier/heated tubing, your overnight consumption can be considerably higher than with the blower alone.
Bottom line: For a portable emergency setup, I'd target 2–4 kWh + 600–1,000 W portable solar. The DELTA Pro 3 is the high-capacity choice; the DELTA 3 Ultra Plus or Jackery HomePower 2000 Plus v2 make more sense if you want something more manageable and less expensive.
If you tell me (1) your refrigerator's approximate wattage/model and (2) your CPAP model, I can calculate how many hours/days each system would realistically run them and how many portable panels you'd need, including a cloudy-day scenario.
