How many kWh of batteries do I Need?
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.
How much energy does a battery use?
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.
What battery should I use for a 100 watt solar panel?
For a 100 watt solar panel, a 100 Ah 12V battery would work well. Remember that your power input needs to roughly match your power output. A 100 Ah 12V battery provides around 50% usable storage. That is why your battery should be able to store at least twice the daily output of your solar panel.
What size battery bank do I Need?
Required Size of Battery Capacity Bank = 999 Ah (Almost 1000Ah) This is the minimum battery bank capacity size you need to run a 900Wh load daily for 3 hours.
