10KWh Battery for what scale family
The suitable household size and electricity usage habits for a 10KWh battery are related,the following analyzes the suitable household situation from different electricity consumption scenarios:
1.Only guarantee basic load
Assuming a household’s basic load includes one 150 watt refrigerator, three 10 watt LED lights,one 10 watt wireless router, and one 100 watt TV. The total power of these devices is 150+3*10+10+10+100=290W.
If calculated based on continuous power supply for 24 hours,the daily power consumption of these devices is 0.29*24=6.96 KWh.
So a 10 kWh battery can provide power to such a household for about 1.44 days,which is basically enough to meet the basic electricity needs of a household for more than a day.
2.Medium load condition:
In addition to the basic load mentioned above,add a 200 watt desktop computer (used for 4 hours per day) and an 800 watt washing machine (used for 1 hour per day). At this time,the daily power consumption of the computer is 0.2*4=0.8KWh,the daily power consumption of the washing machine is 0.8*1=0.8KWh.
Adding the previous basic load’s daily power consumption of approximately 6.96 kWh,the total daily power consumption of this household is approximately 6.96+0.8+0.8=8.56KWh.
A 10 kWh battery can provide power to this household for approximately 1.17 days,which is almost a day’s supply time.
3.High load situation
If an additional 1.5 horsepower (approximately 1100 watts) air conditioner is added and used for 6 hours a day,the daily power consumption of the air conditioner would be 1.1*6=6.6KWh.
At this time,the total daily power consumption of all household devices is 8.56+6.6=15.16KWh.
So a 10 degree battery can only supply power to this household is 0.66 days,which is 16 hours.
4.Conclusion
If there are many high-power appliances in the household that need to run simultaneously for a long time,or if the household has a large population,a large number of electrical devices,and frequent use,a 10KWh battery may not be able to meet the long-term electricity demand and requires a larger capacity battery.
