If you want enough power for 3 days, you'd need 30 x 3 = 90 kWh. As discussed in the post above, the power in batteries are rated at a standard temperature, the colder it is the less power they have. So, with batteries expected to be at 40 to supply 10 kWh, with this data you'd multiply by 1.3 to see you would need 13 kWh of batteries.
To power a house for three days, you should aim for battery storage providing 90 kWh of electrical energy. If a single battery provides 2.4 kWh of energy, you will need approximately 38 batteries. However, this is just a rough calculation, and you need to follow all the steps to accurately determine your power consumption.
When heating and cooling are included in the backup load, a home needs a larger solar system with 30 kWh of storage (2-3 lithium-ion batteries) to meet 96% of the electrical load. The exact number of batteries you need depends largely on your energy goals.
For example, for emergency power you could turn your hot water tank off the breaker, they consume an average of 4 kWh/d. Batteries come in discrete sizes: 18 Ah, 100 Ah, 200 Ah and so forth. When you need more stored energy than can fit in a single battery it is common to put batteries in series in strings, and to have multiple parallel strings.
A single lithium-ion battery is sufficient to power basic lights and electric systems during a power outage. To cover lengthy power outages and sunlight shortage, 8 to 10 batteries are required. Most solar batteries have a capacity of 10 kilowatt-hours.
To determine how much energy a battery can store, multiply its amp-hour (Ah) rating and voltage. For instance, a 12V 200Ah battery can store 2400 Watt-hours of energy. For battery storage that can power a house for three days, aim for 90 kWh of electrical energy.
