Frequently Asked Questions

How Many Ah Is 5kw?

Ah(ampere-hours) refers to the current capacity of the battery.
Ah = A (ampere) x h (hours)

kW refers to the output power (P) of the battery.
1 kW = 1000 W, 5 kW = 5000 W,
Power (P) = voltage (V) x current (I).

Assuming the voltage is 220 volts, the current (I)
I = P ÷ V = 5000 W ÷ 220 V ≈ 22.72 A.

So, the current capacity
Ah = A x h = 22.72 A x 1 h = 22.72 Ah.

When the voltage is 220 V, 5 kW is equivalent to 22.72 Ah. The ampere-hour (Ah) value will vary with different voltage levels.

How Many Amps Is A 5kwh Battery?

Amps refers to current, denoted by the symbol A.
A x h = Ah (current capacity).

kWh refers to the energy consumed when using a power of 1 kW for one hour.
kWh = kW x h, 5 kWh = 5000 Wh.

The relationship between them is:
Watt-hours (Wh) = Voltage (V) x Amperes (Ah).

Assuming the voltage is 48V, then
Amperes (Ah) = 5000 Wh ÷ 48V ≈ 104.17 Ah.

Thus, the current for a 48V 5 kWh battery is 104.17 Amps.

The nominal current of Delong’s 48V 4.8 kWh stackable battery DL-LFP48100 is 100A, calculated as 4800Wh ÷ 48V = 100Ah.

The nominal current of the 25.6V 5.12 kWh wall-mounted battery DL-LFP-HW25200 is 200A, calculated as 5120 Wh ÷ 25.6V = 200 Ah.

What Is The Capacity Of A 5kwh Battery?

Capacity refers to the total amount of electrical energy that a battery can store and provide. It can refer to either energy capacity (kWh or Wh) or current capacity (Ah). The relationship between the two can be established through voltage (V).

kWh = Ah x V

The battery is 5 kWh and assuming the voltage is 24V,
Current capacity (Ah) = 5000 Wh ÷ 24V = 208.3 Ah.

What Is The Discharge Rate Of A 5kwh Battery?

The discharge rate, also known as C-Rate, can be calculated using the battery’s current capacity and the actual discharge current.

Discharge Rate (C-Rate) = Discharge Current (A) ÷ Current Capacity (Ah)
Current Capacity (Ah) = Energy Capacity (Wh) ÷ Voltage (V)

The battery is 5 kWh, which equals 5000 Wh, assuming the battery voltage is 48V, then,
Current Capacity (Ah) = 5000 Wh ÷ 48V = 104.17 Ah.

If the maximum discharge current of the battery is 100A, then,
C-Rate = 100A ÷ 104.17Ah ≈ 0.96C.

The 48V 5kWh battery can discharge in approximately one hour. You can calculate its C-Rate based on the exact current, voltage, and capacity of the battery.

The maximum discharge current of Delong’s 48V 200Ah wall-mounted battery DL-LFP48200 is 200A, and its discharge rate is calculated as follows:
Discharge Rate (C-Rate) = 200A ÷ 200Ah = 1C.

How Much Does A 5kw Battery Cost?

The type, quality, quantity purchased, and brand of the battery can all affect its price.

The Delong 5 kWh lithium battery uses BYD-grade lithium iron phosphate cells, with a price range of 500 to 1,000.

How Many Hours Will A 5kwh Lithium Battery Last?

The usage duration of a 5 kWh lithium battery depends on the connected load power.

Usage Time (hours) = Battery Capacity (kWh) ÷ Load Power (kW)

If the load power is 2 kW, then the battery usage time
h= 5 kWh ÷ 2 kW = 2.5 hours.

You can determine the power supply duration of the 5 kWh battery by calculating the total power of the devices, assessing whether it can meet your needs.

What Can You Run On A 5kWh Lithium Battery?

The 5kWh lithium battery can power electric tools, communication devices, medical equipment, and household appliances such as lights, refrigerators, washing machines, TVs, and small air conditioners. It can also be used for DIY whole-house battery backup systems, as an uninterrupted power supply (UPS) for boats, golf carts, and more.

Delong 5 kWh lithium battery, like Tesla’s solar batteries, has received high praise from many customers.

Is A 5kw Battery Enough To Run A House?

Whether a 5 kW battery can power a home depends on the household’s power requirements and the duration of power supply needed.

If you are looking for a backup power source for critical devices during a power outage, a 5 kW battery may meet your needs. However, if it is intended for daily power supply, you need to consider the power demands of the home.

A 5 kW battery can support households with power demands of up to 5 kW. The greater the power demand, the shorter the battery supply time will be. Households exceeding 5 kW will need to consider a battery with a higher power rating. Of course, you can also consider combining it with other power generation methods, such as a solar system. For example, solar panels can directly power devices during the day, eliminating the need to consider the battery’s capacity. At night, you would rely entirely on the energy stored in the battery.

Therefore, calculating your household’s daily power requirements and the battery’s energy capacity (kWh) is essential for making an accurate assessment. If you prefer not to seek straightforward answers, consult a professional home energy storage manufacturer, such as Delong. We will provide you with an efficient energy solution.
