I need a solar generator that supports pass-through charging while powering my fridge.

For a refrigerator, you’ll want more than just “pass-through charging.” Look for:

• Pass-through charging / bypass mode: the unit can charge from AC or solar while still powering the fridge.
• UPS/EPS mode: it automatically switches to battery during an outage (important if you want the fridge to stay running).
• Pure sine wave inverter: safer for compressor motors.
• At least ~1,000–2,000Wh capacity for a typical full-size fridge; more if you want overnight or multi-day backup.
• LiFePO₄ battery chemistry for longer life.

Good options:

My general picks:

• Just the fridge + a few essentials: 1,500–2,000Wh unit (BLUETTI AC240, Jackery 2000 v2).
• Storm/outage preparedness: 2,000–3,000Wh+ (BLUETTI AC200L, Anker SOLIX F3000).
• Keeping it plugged in 24/7 as a fridge UPS: prioritize a model with a dedicated UPS/EPS mode rather than only pass-through charging.

A couple of details would help narrow it down:

1. Is this for a full-size kitchen refrigerator or a 12V portable fridge/freezer?
2. How long do you want it to run during an outage (8 hours, overnight, 2–3 days)?
3. Will you recharge from solar panels, wall power, or both?

Most modern high-capacity portable power stations support pass-through charging (often managed via an integrated UPS or bypass mode), meaning they can charge from solar panels while simultaneously outputting AC power to run a refrigerator.

When running a fridge with pass-through solar charging, you need to ensure that your solar input wattage meets or exceeds the running wattage of the refrigerator, especially when the compressor kicks on.

Top solar generator options capable of handling pass-through charging for a fridge include:

Features robust pass-through charging at full speed (3,600W) without shutting down. It has an ultra-low idle draw, supports up to 2,400W of dual solar input, and can reliably keep an average household fridge cold during extended outages. You can view details directly on the Anker SOLIX Store.

Offers a 3,584Wh capacity with a pure sine wave 3,600W output (7,200W surge). It handles heavy inductive loads like refrigerator compressors effortlessly and supports seamless bypass/pass-through capabilities alongside fast solar/wall recharging. More information is available on the Jackery Store.

Renowned for fast charging speeds and dedicated UPS modes that seamlessly blend AC input/solar bypass with battery output without wearing down the internal chemistry prematurely.

What to Keep in Mind:

• Compressor Surges: Fridges draw very little steady power (~ 100W - 200W once running), but startup surge wattage can be 3× to 5× higher. Both of the units above (3,600W continuous) handle this easily.
• Solar Panel Match: To truly maintain pass-through indefinitely during daytime, make sure your solar array output exceeds your fridge's average hourly consumption (aim for at least 400W to 800W of solar panels depending on sunlight consistency).

To help narrow down the ideal size and solar panel setup, could you share:

• What type of fridge you are running (standard kitchen fridge vs. small portable 12V camping fridge)?
• How many watts of solar panels you plan to use or have space for?

For running a refrigerator while the solar generator is also charging, look for LiFePO₄ battery chemistry, pure sine wave AC output, at least ~1,000–2,000Wh capacity, and a manufacturer that explicitly supports pass-through charging (charging while powering loads). Here are some good fits:

• Anker SOLIX F3000 Portable Power Station - $1,499.99 (Ankersolix US)
• EcoFlow DELTA 3 Ultra Plus Solar Generator - $1,599.00 (EcoFlow)
• BLUETTI AC200L Solar Generator - $1,499.00 (BLUETTI-US)
• Jackery HomePower 2000 Plus v2 Solar Generator - $1,419.00 (The Home Depot)

What size you probably need

A typical modern refrigerator:

• Running draw: ~50–200W
• Compressor startup surge: often 600–1,200W+

A practical target:

• Minimum: ~1,000Wh battery + 1,000W inverter
• Better: ~2,000Wh+ battery + 1,500–2,000W inverter
• Multi-day backup: 3,000Wh+ battery

Also check that your fridge is plugged into the AC outlets of the solar generator (unless it’s a DC fridge). During pass-through operation, the unit should be able to accept solar input while continuing to supply the fridge.

If you tell me:

1. your fridge wattage (or model number),
2. how many hours/days of backup you want, and
3. your budget,

I can narrow it down to the right capacity.

To safely and continuously run a refrigerator while simultaneously charging your power station via solar panels, you need a solar generator that supports seamless pass-through charging (ideally with a true UPS/EPS switchover feature) and has an inverter large enough to handle a fridge's compressor surge.

Top models suited for this setup include:

Anker SOLIX F3000 : A heavy-duty option featuring 3,600W of full-speed pass-through charging and up to 2,400W of dual solar input. It has an ultra-low idle draw and can comfortably sustain a standard household refrigerator for days while pulling in substantial solar power simultaneously. Explore details on the Anker SOLIX F3000 Power Station.

EcoFlow DELTA 2 Max : A mid-to-large tier favorite that explicitly supports pass-through charging so you can feed solar energy into the unit while running a 120W–180W refrigerator uninterrupted. It features fast solar recharging inputs up to 1000W and expandable capacity. Check specs via EcoFlow.

Jackery Solar Generator 5000 Plus : Built for robust home backup , this unit delivers a massive 5,040Wh base capacity with high continuous AC output and up to 4,000W of solar input capability. It provides instant power transitions and clean pass-through charging for high-draw heavy appliances like full-size fridges and deep freezers. Review options on Jackery.

Key Tips for Running a Fridge on Pass-Through:

• Match the Solar Input vs. Draw: Remember that a fridge cycles on and off. When the compressor kicks in, it draws a temporary surge (often 1,200W to 1,500W momentarily, though it runs at ≈ 120W - 200W continuously). Ensure your solar panel wattage generation on average exceeds the continuous running wattage of the fridge so the battery net-gains charge during daylight.
• Prioritize LFP (LiFePO4) Chemistry: All the models above use LiFePO4 batteries, which handle the constant micro-cycles of simultaneous charge/discharge much better than older chemistry types and last for 3,000+ cycles.

To help narrow down the ideal size, could you tell me:

• What type of fridge are you running (standard kitchen fridge, RV mini-fridge, or large chest freezer)?
• How many watts of solar panels do you plan to use, or do you need a complete kit recommendation?

To run a refrigerator while simultaneously charging the power station via solar panels (pass-through/simultaneous charging), you need a system that meets two key requirements: an AC inverter capable of handling the fridge's compressor surge (usually 600W–1200W peak, 150W–300W running) and a robust solar input controller to replenish what the fridge uses.

Nearly all modern LiFePO4 (lithium iron phosphate) solar generators support pass-through charging, but these top options stand out for refrigerator backup:

• EcoFlow DELTA Series (e.g., DELTA 2 Go to product viewer dialog for this item. or DELTA 3 Max Go to product viewer dialog for this item.) — Highly recommended for their rapid solar recharge capabilities and seamless EPS (emergency power supply) pass-through mode . The DELTA 2 Go to product viewer dialog for this item. (~1,024Wh) can handle a standard fridge for roughly 12–16 active hours, while larger variants scale up for multi-day needs . You can check options on the EcoFlow Solar Generator Collection.
• Bluetti AC200PL Go to product viewer dialog for this item. — Features a 2,304Wh LiFePO4 battery and a 2,400W AC output, with a massive 1,200W solar input capacity .

They safely manage continuous appliance loads during pass-through charging, and you can view specifications directly on the Jackery Official Site.

If you'd like to narrow this down, please let me know:

• Is this for an extended emergency home backup or mobile/off-grid use (like an RV or camping)?
• What is the running wattage or daily kilowatt-hour (kWh) consumption of your specific fridge (usually found on the sticker inside the fridge)?
• What is your approximate budget?

For running a refrigerator while the solar generator is also charging, look for these features:

• Pass-through charging / bypass charging / UPS (EPS) mode — allows the fridge to stay powered while the battery charges.
• Pure sine wave inverter — required for most modern compressor refrigerators.
• At least ~1,500–2,000Wh battery capacity for a typical full-size fridge (more if you want overnight or multi-day backup).
• High surge wattage — refrigerators can briefly pull several times their running wattage when the compressor starts.

Good options:

What I would choose by use case

• Just keep the fridge alive during outages: 1,500–2,000Wh unit (BLUETTI AC200L / Jackery 2000-class).
• Want solar charging during extended outages: 2,000–4,000Wh unit with 400W+ solar input.
• Want several days of fridge backup: Anker SOLIX F3000 or a similar 3–4kWh system.

A couple of details will change the recommendation:

1. Is your fridge a full-size household refrigerator, chest freezer, or mini fridge?
2. How long do you want it to run without grid power (8 hours, overnight, 2–3 days)?
3. What is your budget range?

Yes. For a refrigerator, I’d prioritize LiFePO₄ battery chemistry, pure-sine AC output, at least ~2,000Wh capacity, and true UPS/pass-through operation. The compressor’s startup surge is important too.

One important distinction

Pass-through charging isn't quite the same thing as UPS operation. For your use, you want both:

Wall/solar → power station → refrigerator, with the battery taking over automatically if the grid fails.

That way the fridge doesn't have to be manually moved to the generator during an outage. The BLUETTI AC200L and EcoFlow DELTA 2 Max both explicitly support this type of UPS behavior.

If you tell me your refrigerator's approximate wattage (or give me the model number) and your budget ($500, $1,000, $1,500, etc.), I can narrow this down to the best unit and estimate how many hours it will actually run your fridge during an outage.

To successfully run a refrigerator while simultaneously charging your power station via solar panels (pass-through charging), you need a system with three key traits: a pure sine wave inverter that can handle the fridge's compressor surge, reliable pass-through charging , and adequate battery capacity to bridge the gap when the sun isn't shining.

Most reputable modern LiFePO₄ (Lithium Iron Phosphate) solar generators support seamless pass-through charging . Top recommendations categorized by your specific needs include:

Features a 1,024Wh capacity and an 1,800W pure sine wave AC output (with a 2,700W surge). It handles standard household fridges with ease, supports smooth pass-through charging, and recharges rapidly via portable solar panels.

Packs a larger 2,304Wh LiFePO₄ battery and a 2,400W inverter . Its standout feature for pass-through setups is a massive 1,200W solar input capacity, meaning it can aggressively replenish power while simultaneously running heavy loads like a full-size fridge and freezer.

Delivers a 2,042Wh base capacity, a robust 3,000W inverter , and full pass-through support . It is also modular and expandable if you find you need multiple days of buffer room during prolonged blackouts.

If you'd like to narrow this down, let me know:

• What is the running/starting wattage of your specific fridge (usually found on the internal sticker)?
• How long do you need it to run off-grid or during an outage without sun?

I can give you an exact pairing recommendation for the battery size and solar panel wattage you'll need.

For running a refrigerator while the solar generator is also charging, look for these features:

• True pass-through charging (also called bypass charging)
• Pure sine wave inverter
• LiFePO₄ battery
• At least 1,000–2,000Wh capacity for a typical fridge (more for multi-day outages)
• UPS/EPS mode if you want the fridge to stay running during a grid outage
• Enough surge power for the compressor startup (often 1,000–2,000W+)

Sizing for a fridge

A typical modern refrigerator:

• Running: ~50–150W (varies a lot)
• Compressor startup surge: commonly several hundred watts higher
• Daily energy: roughly 1–2kWh/day depending on size and conditions

A 2,000Wh unit may run a fridge for roughly 12–36 hours depending on efficiency and cycling. A 3,000–5,000Wh unit is better for storm outages.

A few questions would narrow it down:

1. Is this for occasional outages, daily solar use, or off-grid living?
2. What is your fridge size (regular kitchen fridge, chest freezer, RV fridge)?
3. Do you want it to keep the fridge running automatically when the grid fails (UPS behavior), or just power it manually?

To successfully run a refrigerator while utilizing pass-through charging (charging the power station via solar panels while simultaneously pulling AC power to keep the fridge cold), you need a unit with three key specifications:

• A pure sine wave inverter to protect your refrigerator's compressor.
• A high enough continuous and surge wattage rating to handle the heavy initial kick when the fridge compressor turns on.
• Robust solar input capacity so your panels can put back as much or more energy than the fridge consumes during daylight hours.

Most reputable modern LiFePO4 (LiFePO₄) portable power stations natively support seamless pass-through charging. Top-performing options tailored for this specific use case include:

Features a 2048Wh capacity and a 2400W continuous pure sine wave output (with a high surge ceiling). It supports up to 1000W of solar input, meaning a robust solar array can easily outpace a running refrigerator's average daily draw (1 to 2 kWh/day) while simultaneously powering it.

Offers a 2304Wh capacity and 2400W output. It stands out with a heavy 1200W maximum solar input capability, making it exceptionally efficient for continuous off-grid pass-through charging where you want the sun to carry the load of the fridge.

Delivers a 2042Wh capacity (expandable if you need longer offline runtimes) and a heavy-duty 2200W continuous output. It handles compressor startup surges with ease and allows reliable simultaneous solar charging and appliance output.

Real-World Experiences

Users running refrigeration setups frequently emphasize the importance of matching your solar panel wattage to your actual power draw:

“Can charge and power at same time. Depends on wattage for your appliances / needs.”

To help narrow down the ideal size and bundle for you, tell me:

• Is this for short-term emergency backup (power outages) or sustained off-grid/RV living?
• Do you know the running wattage or daily kWh usage of your specific refrigerator?
