How do I calculate battery capacity for my off-grid cabin?

Before you can calculate the battery capacity required for your off-grid cabin, you need to understand your power consumption. This involves identifying all the appliances you will be using and determining their power ratings, as well as tracking the daily usage hours for each appliance.

How long does a 24v battery last?

24V Battery: Run Time = (100 Ah × 24 V) / 200 W = 12 hours 48V Battery: Run Time = (100 Ah × 48 V) / 200 W = 24 hours A higher voltage battery will typically last longer under the same power consumption. Therefore, the 48V battery will run the longest, followed by the 24V & then the 12V battery.

How long should an off-grid cabin battery backup last?

Some off-grid cabin owners may opt for a backup of only one or two days, while others may prefer a week or more. Consider your location, weather patterns, and potential backup power options when deciding on the desired autonomy days. To calculate the total battery capacity required, multiply the daily power consumption by the desired autonomy days.

How much battery capacity do I Need?

For example, if your daily power consumption is 10kWh and you want a backup power option for three days, the total battery capacity required would be 30kWh. It is important to note that battery systems are not 100% efficient, so it is recommended to add a safety margin of around 20% to the calculated total battery capacity.
