Frequently Asked Questions

How Big Is A 15kwh Battery?

The size of batteries depends on the battery type, structural design, and manufacturer. For example, when the capacity is the same, lead-acid batteries are larger in size compared to lithium-ion batteries. Delong’s 15kWh lithium-ion batteries vary in style and size:

• The 15.36kWh stackable lithium battery DL-LFP-HS511003P weighs 157.5 kg, and the dimension is 640*450*510/640 mm.
• The stacked 15.36kWh lithium battery DL-LFP-HS51300 weighs 118 kg, and the dimension is 690*590*258/388 mm.
• The 15.36kWh movable lithium battery DL-LFP-LVM15 weighs 110 kg, and the dimension is 436*262*890 mm.
• The 15.36kWh rack-mounted lithium battery DL-LFP-BE51300 weighs 108 kg, and the dimension is 502*682*265 mm.

How Long Will A 15kwh Battery Last?

The lifespan of batteries depends on the battery type, usage patterns, and brand. Lead-acid batteries typically last 3-7 years, while lithium-ion batteries can last 5-10 years. Delong’s 15kWh lithium iron phosphate (LiFePO4) battery is designed for a lifespan of 12 years and can complete 6500 cycles.

How Many Hours Will A 15kwh Battery Last?

A 15 kWh battery can power for how many hours depends on the power consumption of the equipment. The lower the power, the longer the battery life.
h = kwh ÷ kw

Providing power to a system with a load power of 2 kW, a 15 kWh battery can last for 7.5 hours.
Providing power to a system with a load power of 5 kW, a 15 kWh battery can last for 3 hours.

These are estimated times. Actual usage conditions such as environmental temperature, depth of discharge, BMS (Battery Management System), and other factors will affect the battery’s discharge duration.

What Can A 15kw Battery Power?

A 15 kW battery can power various equipment for homes, businesses, and commercial purposes, such as:

Home appliances: refrigerator, air conditioner, washing machine, electric heater, LED lighting.

Small businesses: laptops, computers, and other office equipment.

UPS (Uninterruptible Power Supply): serves as backup power for homes or commercial facilities to deal with sudden power outages.

Renewable energy storage: stores solar energy during the day and releases electricity at night.

In addition, a 15 kW battery can also charge electric vehicles and power boats, golf carts, and other vehicles.

Can 15kw Power A House?

15 kW is equivalent to 15000 watts (W). The peak electricity demand of many households is much lower than 15 kW. Therefore, a 15 kW battery can power a house, but the duration of power supply varies based on power consumption. Larger households with higher daily electricity demands will have shorter power supply durations.

If your peak power demand exceeds 15 kW, consider a solar power generation system or expanding the scale of your energy storage system. For small households with 1-2 people, a 15 kW battery is sufficient to provide power for your house throughout the day, and you may even have surplus electricity to sell back to the grid, offsetting energy costs.

Feel free to consult Delong’s energy experts; we will provide detailed planning for your home’s electrical system.

How Long Does It Take To Charge A 15kwh Battery?

The charging time of a 15 kWh battery depends on the power of your charger. The higher the power, the shorter the charging time.

Charging time (hours) = Battery capacity (kWh) ÷ Charging power (kW)

For example, if the charging power is 5 kW, then
15 kWh ÷ 5 kW = 3 hours.
It takes 3 hours to fully charge a 15 kWh battery with a 5 kW charger.

Additionally, the charger’s efficiency, battery condition, and charging mode will also affect the charging duration.

How Many Panels Can Charge A 15kwh Lithium Battery?

Assuming the solar panel has a power output of 410W and there is an average of 5 hours of sunlight per day, then:
410W x 5h = 2050Wh
Each solar panel can generate 2050 watt-hours (Wh) of energy per day.

To charge a 15 kWh lithium battery:
15000Wh ÷ 2050Wh ≈ 7.3 panels

Therefore, if there are 5 hours of sunlight each day, you would need approximately 8 solar panels rated at 410W each to charge a 15 kWh lithium battery.

The exact number of panels required can vary based on local sunlight conditions, charging efficiency, and the placement of solar panels.
