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

Virtually all modern lithium iron phosphate (LiFePO₄) solar generators (portable power stations) support pass-through charging —meaning they can output power to your refrigerator while simultaneously being charged by solar panels or an AC wall input.

However, to successfully run a household fridge while charging via solar, you need to match the battery capacity (Wh), inverter output (W) , and solar input capacity (W) so that your panels can replenish energy faster than (or equal to) what the fridge consumes.

Recommended Solar Generator Options

EcoFlow Delta 2 — Capacity: 1,024Wh | Inverter: 1,800W (2,400W surge). A reliable mid-size option that easily handles a standard kitchen fridge's startup surge and supports seamless pass-through charging.

Bluetti AC200PL — Capacity: 2,304Wh | Inverter: 2,400W. Excellent value with a massive 1,200W solar input capacity, making it ideal for continuous off-grid or extended outage pass-through charging where panels need to pump high wattage back into the unit quickly.

Jackery HomePower 3600 Plus — Capacity: 3,584Wh | Inverter: 3,600W. Heavy-duty option if you have a large multi-door refrigerator/freezer combo and want multi-day autonomy backed by robust solar input.

Key Rules for Pass-Through Fridge Setup

1. Inverter Headroom: A standard fridge running compressor cycles draws around 100 W to 200 W when active, but its startup surge can demand 600 W to 1,200 W momentarily. Ensure your continuous inverter rating is at least 1,500W.
2. Solar Panel Match: If your fridge consumes roughly 1,200 Wh to 1,800 Wh a day, a tiny 100W solar panel won't keep up during peak pass-through. Aim for at least 400W to 800W of solar array input to ensure the battery stays topped off through daily cycles.

If you can share:

• The approximate wattage or size of your refrigerator (standard kitchen fridge vs. mini/RV fridge)
• How long you need it to run continuously on solar pass-through

I can help you pinpoint the exact battery size and solar panel wattage required.

For running a refrigerator while the solar generator is also charging, you’ll want a unit that explicitly supports pass-through charging (sometimes called EPS/UPS mode) and has enough inverter surge capacity for the fridge compressor.

Best picks by use case

Best overall for home fridge backup

• • Large expandable capacity (good for multi-day outages)
  • High inverter output for refrigerators and other appliances
  • Better choice if you may later add more loads (freezer, lights, internet, etc.)

Best value for a typical refrigerator

• • 2,048Wh battery
  • 2,400W inverter output
  • Plenty of headroom for most full-size refrigerators (which often run at much lower wattage but have startup surges)

Best if you specifically care about pass-through operation

• • Advertised with pass-through charging capability and designed for appliance backup use

Portable but still fridge-capable

• • 2–24kWh expandable system
  • Good fit if you want something portable that can grow into a larger backup setup

What I’d look for for a fridge

• Battery: at least ~1,500–2,000Wh for overnight use
• Inverter: at least 1,500W continuous, preferably 2,000W+
• Surge rating: around 3,000W+ is safer for compressor startup
• Battery chemistry: LiFePO₄ preferred for longevity
• Pass-through behavior: confirm it can charge from AC/solar while the AC outlet remains active (some cheaper units have limitations)

If you tell me:

1. your fridge size/model (or its running watts),
2. how many hours/days you want backup, and
3. whether you’ll charge from wall outlet, solar panels, or both,

I can narrow it down to the right capacity.

To safely run a household refrigerator while utilizing pass-through charging (charging the power station via solar panels while simultaneously outputting AC power to your fridge), you need a unit with a robust LiFePO4 battery, a pure sine wave inverter capable of handling compressor surge spikes (1,000W - 1,200W surge), and high solar input capacity.

Almost all modern tier-1 portable power stations support pass-through charging, but these three options stand out for running a fridge seamlessly:

Highly recommended as a sweet spot for home backup . The standard EcoFlow Delta 2 features a 1,024Wh capacity and an 1,800W output, easily handling a standard fridge's running and surge watts. It supports seamless pass-through charging and fast solar input. If you have a larger fridge or deep freeze that needs multi-day runtime, the EcoFlow Delta 2 Max Go to product viewer dialog for this item. scales the capacity up.

A value-packed heavyweight champion for continuous loads. It features a 2,304Wh capacity and a continuous 2,400W AC output. Its standout feature for solar pass-through is a massive 1,200W solar input capacity, meaning on a sunny day, your solar panels can pump massive energy back into the unit even while the compressor is actively cycling.

Jackery units officially support reliable pass-through charging across their lineup . The Jackery Explorer 1000 Plus gives you expandable capacity and a pure sine wave output designed to protect sensitive compressor electronics.

Crucial Math for Your Setup

• Running vs. Surge Watts: A standard house fridge typically draws only 100W - 150W when running, but the compressor startup spike can jump to 1,200W momentarily. Ensure your chosen inverter has at least a 1,800W continuous rating.
• Solar Panel Matching: If your fridge averages 150W over an hour (150Wh), your solar array needs to generate more than that average draw during peak sunlight hours if you want the battery to net-gain charge while the fridge is plugged in. A 200W to 400W solar panel setup is usually the minimum practical recommendation for continuous daytime pass-through.

To narrow down the exact model and solar panel wattage you need, let me know:

• Is this for a standard kitchen fridge , a mini-fridge , or a 12V portable camp/RV fridge?
• Do you need it to run for just a few hours or indefinitely over multiple cloudy days?

For a solar generator that can keep a refrigerator running while it is charging, you’ll want a unit with pass-through charging (sometimes called EPS/UPS mode) and enough inverter surge capacity for the fridge compressor startup. A typical full-size fridge may only average ~50–150W while running, but the startup surge can be much higher.
