Estimate refrigerator runtime from battery capacity and average power use. Check the refrigerator’s starting demand against the power station’s output rating, then allow for inverter losses and idle draw. The estimates below use assumed loads; we have not measured a refrigerator runtime test.
A refrigerator needs a compatible voltage and enough continuous and startup output for its compressor. Check the refrigerator's nameplate and manual against the station before buying. Runtime is then watt-hours ÷ average watts. The Solar Lab found manufacturer claims of “it’ll power your fridge for 3 days” closer to 7 hours— which is why this table is arithmetic, not a copied spec-sheet day count.
Columns below are assumed average loads of 50W, 100W, and 150W (a cycling compressor, not the nameplate). They are not measurements of a fridge in our shop. Hours = manufacturer capacity ÷ that load.
A watt-hour (Wh) is stored energy: watts × hours. A 1,000Wh pack can theoretically supply 100W for 10 hours, or 50W for 20 hours. Real runtime is shorter once you count inverter loss and idle draw.
Hours below are estimates from capacity ÷ labeled average watts. They are not first-hand measurements of an appliance we ran.
| Labeled average load | Estimated hours |
|---|---|
| 50W average | 20 h |
| 100W average | 10 h |
| 150W average | 6.7 h |
The Bluetti FridgePower is marketed for fridge and sump-pump backup. The manufacturer publishes 4W self-consumption (manufacturer Amazon listing ("4W Self-Consumption"))on a 2,016Wh pack — at that idle alone, about 21 days of doing nothing, before the fridge even starts. The Solar Lab’s ~80W idle on an Anker F3800 would empty the same pack in about 25 hours with no load.
These options show three different tradeoffs in the verified catalog: a published idle figure, a lower-cost capacity/output match, and more output margin. None is a refrigerator runtime test.
Published low idle draw
Why it fits: 2,016Wh and 1,800W AC are paired with the catalog's only manufacturer-published 4W self-consumption figure.
Tradeoff: The low idle figure is a manufacturer specification, not a refrigerator runtime test; check compressor startup demand.
Current Amazon price: $898.97
Capacity and output for the price
Why it fits: 2,048Wh and 2,400W AC provide a straightforward capacity/output match for a 120V fridge plan.
Tradeoff: 45 lb and no published idle figure mean carry weight and standby draw still need checking.
Current Amazon price is unavailable in the latest price check.
More output margin
Why it fits: 2,048Wh and 2,400W AC give more output margin while keeping the pack at 41.7 lb.
Tradeoff: No manufacturer idle figure is recorded and this model is not expandable; verify the refrigerator's running and startup demand.
Current Amazon price: $899.98

The Pecron F5000LFP we own is in the table from manufacturer capacity only. We have not published a first-hand fridge-runtime test for it. The array we actually wired is on the 12-panel build and the F5000LFP model page.
Outage sizing beyond a single fridge is on home backup.
