Can a 400ah Battery Power a House?
This depends on how much electricity your house uses. If you use 5kWh per day, the 48V 400Ah battery can fully power your home.
How Many Solar Panels Do I Need to Charge a 400ah Lithium Battery?
The total energy of the 48V 400Ah lithium battery is 20480Wh. Assuming a system efficiency of 95% and 5 hours of effective sunlight per day, the battery requires 21558Wh of solar energy. The total photovoltaic power needed per hour is 4311.6W.
20480 ÷ 95% = 21558Wh
21558Wh ÷ 5h = 4311.6W
The number of solar panels varies by their power:
330W solar panel: 4311.6W ÷ 330W ≈ 13.06, which is 14 panels
440W solar panel: 4311.6W ÷ 440W ≈ 9.8, which is 10 panels
