Today’s lithium-ion batteries offer anywhere from 3 to 18 kWh of usable capacity per battery, although a majority are between 9 and 15 kWh. In many cases, batteries can be coupled together to provide more storage.
In this case, you would require a 12.6 kWh lithium battery bank. In ampere-hours, it will be 1050 Ah (for 12V). This means that you will need 10 lead-acid batteries or 2 lithium-ion batteries. Also, this is an off-grid setup where you rely completely on energy storage for your needs—this system can cover your needs for up to 3 days.
Battery Size = 10 kWh x 2 x 1.2 = 24 kWh That means you would need a 24 kWh lead acid battery bank to store the energy generated by your solar system and meet your daily power consumption. You can also convert this into ampere-hours by dividing the kWh by the battery voltage. For a 12V battery, this will become 24 kWh / 12V = 2000 Ah
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.
