FAQ
Is a 400ah Lithium Battery Worth the Cost?
The 48V 400Ah lithium battery is well worth the investment. It has large capacity, long life, good compatibility, and high flexibility. It can effectively increase your power independence, lower your electricity costs, and even improve your project earnings.
How Long Will 400ah Lithium Last?
Delong 48V 400Ah lithium battery can be used for ten years. The runtime after each full charge depends on the devices connected. The higher the power of the devices, the shorter the runtime.
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
