Simulated runtimes (not measured)

Nobody tested this unit for this page. These figures come from a computer simulation of the C1000 Gen 2, and they are estimates. The plain runtime table below divides energy by average draw at 85% efficiency. The simulation also charges the battery for the power the inverter burns just by being switched on, which is why small loads come out shorter. Where we have measured a unit, the measurement is shown separately and labeled as measured.

Nonstop runtime from full to battery cutoff. Likely range = middle 80% of 200 simulated runs with the uncertain inputs varied. The inverter idle draw is assumed, not published: we assumed about 20 W for this model, varied from 12 to 30 W. If the real figure is lower, real runtimes land closer to the spec-sheet column.

How this was simulated
  • The battery is stepped down every 2 minutes until it reaches cutoff, for 200 runs per device. Results are seeded, so the page shows the same numbers on every build.
  • Battery draw = load + inverter idle draw + 4–8% of the load + a loss that rises with load squared (4% at full output).
  • Usable capacity = 92–98% of rated Wh, for protection cutoff and aging.
  • At 0 °C, 80–90% of that capacity is assumed available.
  • Fridges cycle on and off every 30–50 minutes at the share of the time set by their average draw. The inverter idle draw continues while the compressor is off.
  • Devices that exceed this model's output or surge rating are left out. Loads are US 120 V devices.

Questions

How long will the Anker SOLIX C1000 Gen 2 run a refrigerator?
About 15 hours for a typical ENERGY STAR full-size fridge averaging 58 W, assuming 85% inverter efficiency. Older or larger fridges use more. Try your own numbers.
Can the Anker SOLIX C1000 Gen 2 run a microwave?
Yes. A typical 1,000 W microwave pulls about 1,500 W from the outlet, within its 2,000 W continuous output. A full battery gives about 35 min of cooking.
How many amp-hours is the Anker SOLIX C1000 Gen 2?
The Anker SOLIX C1000 Gen 2 works out to about 85.3 Ah at 12 V, or 80 Ah at 12.8 V, the nominal voltage of a 12 V LiFePO4 battery. Both are our conversion of Anker SOLIX's 1,024 Wh rating: amp-hours = watt-hours ÷ volts. The battery inside may run at a different voltage, so an amp-hour figure in a manual or on a product listing can look very different for the same energy. For scale, a 12 V 100 Ah LiFePO4 battery holds 1,280 Wh, so this model holds about 80% as much as one. How we convert amp-hours.
How long does the Anker SOLIX C1000 Gen 2 take to charge?
Anker SOLIX's published charging claim: “100% in 49 min (UltraFast, 1,600W)”. Max AC charging power is 1,600 W. With solar, it accepts up to 600 W. With 600 W of panels that's roughly 2.3 hours of good sun from empty.
Is the Anker SOLIX C1000 Gen 2 expandable?
No. Its capacity is fixed at 1,024 Wh.
Does the Anker SOLIX C1000 Gen 2 work as a UPS?
Anker SOLIX lists a 10 ms switchover time, so it can keep devices like routers and computers running when the power drops. Check that your specific device tolerates the switch before relying on it for anything critical.
