Will the Anker SOLIX C1000 Gen 2 run a refrigerator?
Yes. The Anker SOLIX C1000 Gen 2 can start and run a full-size fridge, and its 1024 Wh battery lasts about 16 hours at the ENERGY STAR average draw.
Yes: about 16 h
On a refrigerator's average draw of 52 W. Formula: 1,024 Wh x 0.85 / load W.
The checks
| Check | Station | Refrigerator | Result |
|---|---|---|---|
| Running watts | 2,000 W rated[1] | 700 to 725 W[4][5][6] | OK |
| Starting surge | 3,000 W[1] | 2,200 to 2,900 W[4][5] | OK |

Wattage figures we used
| Figure | Watts | Notes | Source |
|---|---|---|---|
| Running | 700 W | Generator sizing chart figure | [4] |
| Running | 700 W | Listed as Refrigerator/Freezer | [5] |
| Running | 725 W | Nameplate figure for a frost-free 16 cubic foot refrigerator | [6] |
| Starting | 2,200 W | Starting watts | [4] |
| Starting | 2,900 W | Listed as Refrigerator/Freezer. Derived: 700 running + 2200 additional starting watts in Generac's chart | [5] |
| Average | 52 W | Median annual energy use of 2986 ENERGY STAR certified full-size (compact = No) residential refrigerators, 457 kWh a year, divided by 8760 hours (457 / 8.76 = 52 W) | [7] |
For a fridge, a power station needs rated output above the compressor's running draw, a surge rating above its starting draw, and enough energy to last through the outage.
The C1000 Gen 2 is rated for 2000 W continuous and 3000 W surge. Generator charts list a fridge at 700 to 725 W running and 2200 to 2900 W starting, so both checks pass with the highest figures we found.
The battery is the limit. A fridge cycles, and the median full-size ENERGY STAR model uses 457 kWh a year, an average of 52 W. At that rate the 1024 Wh battery lasts about 16 hours from full, with our 0.85 efficiency assumption since Anker does not publish one. Larger, older or side-by-side fridges use more.
The C1000 Gen 2 does not take expansion batteries, so for a full day you would need to recharge. Its listed solar input is 600 W, and it charges from the wall at up to 1600 W when power comes back. Enter your own fridge's average watts in the calculator if you know its annual kWh.

Questions
Can the Anker SOLIX C1000 Gen 2 run a fridge overnight?
Yes. At the median ENERGY STAR average of 52 W it lasts about 16 hours from a full charge.
Can I add a battery to the C1000 Gen 2 for longer fridge runtime?
No. Anker lists the C1000 Gen 2 as not expandable, so longer runtime means recharging from solar or the wall.
Runtime calculator
Runtime (hours) = battery Wh x inverter efficiency / load W
Efficiency is the share of battery energy that reaches the outlet. Where the maker does not publish it we use 0.85. Average W is for loads that cycle on and off, like a fridge; leave it blank to use running watts. Starting surge assumes one motor starts at a time. How the estimates work.
