FAQ
How Long Will A 14kWh Battery Last?
The Delong 14kWh battery has a lifespan of up to 12 years. Its runtime depends on the load power—the higher the power, the shorter the runtime. When connected to a 1000W load, the 14kWh battery can run for 14 hours. With an 8kW load, it can last for 1.75 hours.
How Much Does a 14kWh Solar Battery Cost?
The price of the Delong 14kWh solar battery ranges from $1,100 to $1,400, depending on the purchase quantity and battery accessories.
How Many Solar Panels Do I Need To Charge A 14kWh Battery Pack?
We need to consider the power of the solar panels and the effective sunlight hours per day.
For example, if you are using 410W solar panels with 5 hours of effective sunlight daily, each panel can generate 2,050Wh of energy per day:
Daily energy per panel = 410W × 5h = 2,050Wh
To produce 14kWh of energy, you would need around 7 panels:
Number of panels needed = 14,000Wh ÷ 2,050Wh ≈ 7 panels
This calculation is based on ideal conditions. In reality, factors like cloudy weather, inverter losses, and backup storage need to be considered. For more accurate calculations, contact Delong, a professional lithium battery manufacturer. We can provide detailed estimates based on your location and daily energy consumption.
