People also ask

How long will a 15 kWh battery last?

It depends on the power of the home appliances you use. For example, if the power of your electrical fan is 1000w, then the 15kwh battery can last: 15Kwh/1000W = 15 Hours. You can refer to the formula below to calculate the last time for the 15 kva lithium battery:

time(Hours) = Capacity(KWh) * 1000/Power(W).

How long does it take to charge a 15kWh battery?

The time to charge the 15kwh battery depends on the power of the battery charger, and the temperature around the battery. The higher power the battery charger is, the shorter the time for charging the battery.  You can refer to the formula below to calculate the time for charging:

Time = Battery capacity(KWh) / charging rate(KW).

For example,

A 5kw battery charger can charge full of the lithium battery for 15KW/5KW=3 hours;

A 10kw battery charger can charge full of the lithium battery for 15KW/10kw = 1.5 hours.

And the condition above is under the lithium battery operating temperature:

Can a lithium battery last 20 years?

HBOWA lithium lifepo4 batteries have a long life cycle of over 6000 times, which means the design life is 10 years, and we guarantee the warranty time of the 15kwh lifepo4 battery is 5 to 10 years. 10 years later, the capacity of the battery begins to decline, but it can still be used normally. This attenuation of battery capacity due to factors such as the passage of time and the frequency of battery usage is a normal phenomenon.

How many solar panels do I need for a 15kwh lithium battery?

Considering the efficient sunlight time is 4 hours per day, and we choose 550w solar panels as the example, so each solar panel can generate about: 550 watt * 4 hours = 2200wh per day. To charge the 15kw lithium battery,  we still need about the number of solar panels:

15kwh / 2200 wh = 6.8 pieces.

That means we need about 7 pieces of 550w solar panels to charge the 15kwh battery. In our daily use of solar systems, it still depends on the solar installation,  seasons, weather, charging efficiency rate, etc factors.

HBOWA can provide you with whole solar system solutions for free, feel free to contact us directly for free professional suggestions.

How many lithium batteries do I need for a 5kw solar system?

For a 5kw solar system, if we consider the efficient hours of the sunlight is 4 hours per day, and the power generation rate is 100%, then we will get the energy: 5KW * 4 Hours = 20kWh. If you need to store the full energy into the 5kwh lithium battery, and there’s no energy loss, then you will need the number of the solar battery:

20KWh / 5kwh = 4 pieces.

The calculation above is under the ideal conditions. The actual usage of the 5kw solar system may have various results. There are many variable factors involved. For example: the efficiency of transferring the electrical energy generated by the solar panels to the lithium batteries, the depth of battery charge and discharge (to avoid affecting the battery life, we usually recommend it to be at 80%), the amount of electrical energy you need to store (sometimes you will use the electrical energy generated by the solar energy during the day and store the remaining energy in the batteries for use at night or on cloudy and rainy days), and so on.
