Engineering Breakdown: Running a Full-Size 26 Cu. Ft. French Door Refrigerator on the Anker SOLIX F2000 (PowerHouse 767)
When pairing the Anker SOLIX F2000 (PowerHouse 767) (2,048 Wh LiFePO4 capacity, 2,400 W continuous, 3,600 W surge) with a Full-Size 26 Cu. Ft. French Door Refrigerator (160 W running, 1,100 W starting surge), the system operates at 7% of continuous inverter capacity on a 120 V North American circuit and 7% on a 230 V UK/EU/AU circuit. At a 100% duty cycle and 85% inverter efficiency, a full battery delivers roughly 10.9 hrs of off-grid runtime. Wiring the connection over a 25 ft run calls for a 15 A breaker and 14 AWG copper, terminated at a NEMA 5-15P connection.
1. Compatibility Verdict & Inverter Load Utilization
In North American mode the Full-Size 26 Cu. Ft. French Door Refrigerator loads the Anker SOLIX F2000 (PowerHouse 767)'s inverter to 7% of its 2,400 W continuous rating and 31% of its 3,600 W surge rating. Both figures are under the 80% sustained-load guideline, so this is a comfortable, verified match with 2,240 W of spare capacity for lights, a router or a refrigerator on the same unit.
| Check | Load requires | Anker SOLIX F2000 provides | US/NA | UK/EU/AU |
|---|---|---|---|---|
| Continuous output | 160 W | 2,400 W | Pass | Pass |
| Start-up surge | 1,100 W | 3,600 W | Pass | Pass |
| Voltage | 120 V / 230 V | 120 V / 230 V | Pass | Pass |
| Connection | NEMA 5-15P | NEMA TT-30R / 5-20R | UK/EU/AU: BS 1363 13A / Schuko CEE 7/4 / AS/NZS 3112 10A | |
Compressor appliances such as refrigerators and freezers draw very little on average — 160 W while running — but need 1,100 W for a moment each time the compressor kicks on. Their duty cycle is typically 30–40%, which is why a modest battery can keep food safe for a long time. The Anker SOLIX F2000 (PowerHouse 767)'s 3,600 W surge rating comfortably handles each restart.
As a portable power station, the Anker SOLIX F2000 (PowerHouse 767) integrates the LiFePO4 battery, inverter, MPPT solar controller and AC outlets in one chassis, so it can be wheeled to the load or connected to a transfer switch through its NEMA TT-30R / 5-20R outlet.
2. Real-World Runtime by Duty Cycle
Nameplate capacity is not usable capacity. DC-to-AC conversion, battery management overhead and cell protection reduce the 2,048 Wh rating to about 1,741 Wh of deliverable AC energy (85% system efficiency). Duty cycle is the share of each hour the load actually draws its running power — thermostats, pressure switches and intermittent use all lower it.
| Duty cycle | Average draw | Runtime (no solar) | Energy per 24 h |
|---|---|---|---|
| 25% | 40 W | 43.5 hrs | 1.0 kWh |
| 50% | 80 W | 21.8 hrs | 1.9 kWh |
| 65% | 104 W | 16.7 hrs | 2.5 kWh |
| 100% | 160 W | 10.9 hrs | 3.8 kWh |
Even at a 50% duty cycle the battery lasts 21.8 hrs, so plan on solar, grid or generator recharging for anything longer than an evening outage.
3. NEC 125% Breaker & Copper Wire Gauge Sizing
NEC 210.19(A) and 210.20(A) require conductors and overcurrent devices for continuous loads — anything running three hours or more, which includes EV charging and HVAC — to be rated at 125% of the load current. For this pairing: 160 W ÷ 120 V = 1.3 A, × 1.25 = 1.7 A, which rounds up to the next standard NEC 240.6 size of 15 A. The conductor must be protected by that breaker (75 °C ampacity at least 15 A) and keep round-trip voltage drop at or below 3%, so longer runs are upsized.
Voltage drop % = (2 × L × I × R) ÷ V × 100
North America (NEC, THHN copper, 75 °C)
| One-way distance | Breaker | Min. copper | Voltage drop | Note |
|---|---|---|---|---|
| 25 ft (7.6 m) | 15 A | 14 AWG | 0.17% | Sized by ampacity |
| 50 ft (15.2 m) | 15 A | 14 AWG | 0.34% | Sized by ampacity |
| 75 ft (22.9 m) | 15 A | 14 AWG | 0.51% | Sized by ampacity |
| 100 ft (30.5 m) | 15 A | 14 AWG | 0.68% | Sized by ampacity |
UK / EU / Australia (IEC 60364 / BS 7671, PVC copper, method C)
IEC-based codes size protection by design current rather than a blanket 125% multiplier: Ib ≤ In ≤ Iz. At 230 V the load draws 0.7 A, so a 6 A Type B/C MCB with RCD protection applies. In the UK, BS 7671 Section 722 additionally requires a dedicated circuit and Type A or Type B RCD for EV charge points.
| One-way distance | MCB | Min. cable | Voltage drop |
|---|---|---|---|
| 7.5 m (25 ft) | 6 A | 1.5 mm² | 0.05% |
| 15 m (49 ft) | 6 A | 1.5 mm² | 0.11% |
| 22.5 m (74 ft) | 6 A | 1.5 mm² | 0.16% |
| 30 m (98 ft) | 6 A | 1.5 mm² | 0.22% |
Because the current is modest, 14 AWG copper stays within the voltage-drop target all the way to 100 ft.
4. Solar Array Recharge Time Breakdown
The Anker SOLIX F2000 (PowerHouse 767) accepts up to 1,000 W of photovoltaic input. Real arrays rarely deliver nameplate output, so we apply an 80% harvest factor for MPPT conversion, cell temperature and soiling, and convert hours to days using 4.5 peak-sun-hours — a conservative annual average for the US, southern Europe and Australia (UK winters can fall below 1.5).
| PV array | Real harvest | 0–100% recharge | Sun-days @ 4.5 PSH | Net with load @ 50% |
|---|---|---|---|---|
| 400 W | 320 W | 6.4 hrs | 1.4 | +240 W |
| 800 W | 640 W | 3.2 hrs | 0.7 | +560 W |
| 1,000 W | 800 W | 2.6 hrs | 0.6 | +720 W |
A typical 800 W portable array refills the battery in about 3.2 hrs of strong sun, while maxing out the 1,000 W input cuts that to 2.6 hrs. To fully offset the Full-Size 26 Cu. Ft. French Door Refrigerator at a 50% duty cycle (80 W average) during daylight you need roughly 100 W of panels, which this unit can accept.
5. Frequently Asked Questions
Can the Anker SOLIX F2000 (PowerHouse 767) run a Full-Size 26 Cu. Ft. French Door Refrigerator?
Yes. The Anker SOLIX F2000 (PowerHouse 767) delivers 2,400 W continuous and 3,600 W surge, covering the Full-Size 26 Cu. Ft. French Door Refrigerator's 160 W running and 1,100 W start-up draw at 7% inverter utilization.
How long will the Anker SOLIX F2000 (PowerHouse 767) run a Full-Size 26 Cu. Ft. French Door Refrigerator?
With 2,048 Wh of capacity and 85% inverter efficiency, expect about 10.9 hrs of continuous operation and 21.8 hrs at a 50% duty cycle. Adding solar input during the day extends this further.
What breaker and wire size do I need to connect a Full-Size 26 Cu. Ft. French Door Refrigerator to the Anker SOLIX F2000 (PowerHouse 767)?
In the US, 160 W at 120 V is 1.3 A; applying the NEC 125% continuous-load rule gives 1.7 A, so use a 15 A breaker and 14 AWG copper for runs up to 25 ft (0.2% voltage drop). In 230 V markets the load draws 0.7 A, protected by a 6 A MCB on 1.5 mm² cable for runs up to 7.5 m. Receptacle: NEMA 5-15P (US) or BS 1363 13A / Schuko CEE 7/4 / AS/NZS 3112 10A (UK/EU/AU).
How long does it take to recharge the Anker SOLIX F2000 (PowerHouse 767) with solar panels?
With an 800 W array and an 80% real-world harvest factor, a full recharge takes about 3.2 hrs of peak sun (0.7 days at 4.5 peak-sun-hours). At its maximum 1,000 W solar input it drops to 2.6 hrs.
Methodology & safety note
Specifications come from manufacturer datasheets in our open dataset; ampacity and resistance values follow NEC Table 310.16 and Chapter 9 Table 8, and BS 7671 Appendix 4. Calculations assume copper conductors, 30 °C ambient and no bundling derating. Inverter-to-panel connections require a listed transfer switch or interlock to prevent back-feeding the grid. These results are an engineering estimate, not a substitute for a licensed electrician and local permit. See our methodology and safety disclaimer.
