How Much Does It Cost to Charge an Anker SOLIX F3800?
Calculate the grid recharge cost for the 3,840Wh Anker SOLIX F3800 using current EIA electricity prices and a transparent efficiency assumption.
The SOLIX F3800 stores 3,840Wh nominally. A full grid recharge therefore draws more than 3.84kWh once charging losses are included.
What matters
- Anker lists 3,840Wh nominal capacity for the F3800.
- At 90% efficiency, a full refill uses about 4.27kWh from the wall.
- State electricity rates create a larger percentage spread than small efficiency differences.
- Daily or weekly cycling is better modeled with monthly and annual charging cost.
How to size it
- Convert 3,840Wh to 3.84kWh.
- Divide by charging efficiency.
- Multiply by cents/kWh converted to dollars.
- Scale by partial state-of-charge change when appropriate.
At 18.16¢/kWh and 90% efficiency, a full nominal recharge costs about $0.77. Using EIA state averages, the same refill is roughly $0.52 in North Dakota and $1.96 in Hawaii.
Common buying mistakes
- Assuming 3.84kWh at the battery equals 3.84kWh from the meter.
- Ignoring time-of-use rates.
- Using charge cost as a proxy for battery economics.
Even a large F3800 is inexpensive to recharge from the grid; system economics are driven primarily by hardware, cycling and what backup energy replaces.
Use your actual tariff when possible
State averages are useful for comparison, but the best charging-cost estimate comes from your own cents-per-kWh rate, the percentage of battery being restored and a realistic charging-efficiency assumption.
