Best Solar Generators For Home Backup [2024]: Top 10 Picks + Buying Guide
When you''re considering powering your home using solar batteries, it''s crucial to understand the number of batteries are needed to power a house. This article will help you calculate the number of solar batteries required, and the factors to consider to achieve a reliable off-grid solar power setup.
For example, if your home uses 30 kWh daily and you want two days of autonomy, you''d need approximately 60 kWh of storage. Dividing this by the battery capacity will give you the total number of batteries needed. If each battery holds 5 kWh, you''d need 12 batteries to cover two days (60 kWh ÷ 5 kWh = 12 batteries).
The first step in determining the number of solar batteries you need is understanding your home''s daily energy consumption. According the U.S. Energy Information Administration (EIA), the average U.S. home consumes about 30 kWh (kilowatt-hours) of electricity per day, but this can vary significantly based on home size, appliances, and energy habits. Calculate your home''s specific energy requirements by checking your electric bill, which will typically show your monthly energy usage in kWh.
You may wonder "how long will a 30kWh battery system last in my house?" or "30 kWh battery run how long". The duration it will last depends on your energy consumption, for example, your lifestyle, habits and energy awareness. For an average household using 30 kWh per day, a fully charged 30 kWh battery would last approximately one day.
For homes with lower energy requirements or when only essential appliances are used, a 30kWh battery system may last longer. Conversely, if multiple high-wattage appliances run simultaneously (such as an air conditioner, oven, and water heater), the battery will deplete more quickly.
Consider high-quality LiFePO4 lithium batteries like Redodo solar off-grid batteries. These deep cycle batteries can provide over 4000 cycles at 100% DOD and 15,000 cycles at 60%DOD. However, it''s not recommended to frequently discharge 100% of their capacity for extending the battery lifespan. We recommend stopping the discharge when the State of Charge (SOC) below 20%.

The number of lithium batteries required depends on your home''s daily energy consumption, typically measured in kilowatt-hours (kWh). For example, if your house uses 30 kWh per day, you would need a battery bank with a total capacity of 30 kWh:
A traditional 12V 200Ah lead-acid battery stores about 2.4 kWh of energy, while a 12V 200Ah LiFePO4 battery can offer 2.56 kWh of energy. To power a house consuming 30 kWh per day, you would need approximately 13 of lead-acid batteries or 12 of LiFePO4 batteries.
A 12V 100Ah lead-acid battery stores 1.2 kWh of energy, and a 12V 100Ah LiFePO4 battery provides 1.28 kWh of energy. To power a house that uses 30 kWh per day, you would need about 25 of lead-acid batteries or 24 of LiFePO4 batteries. However, adding more batteries increases the system size and complexity, so it''s recommended to option for higher-capacity batteries to simplify installation.
For a 10kW solar system, you typically need a battery capacity that can store at least one day''s worth of energy production. If the sunlight duration is 5 hours a day, then it often get around 5 kWh of storage capacity. It is about 2 of 12V 300Ah lithium batteries or 200Ah batteries, or 4 of 12V 100Ah batteries.
We inject passion, integrity, respect, and professionalism into our LiFePO4 batteries, we hope that Redodo LiFePO4 battery not only power for you, but also bright your life with our excellent customer service. We are here to help:
