Calculate Daily Energy Consumption
Find your daily energy use in kilowatt-hours (kWh). You can check your power bill for your monthly kWh and divide by 30 to get your daily average.
For example, if your bill says you use 900 kWh in a month, your daily use is 30 kWh.
List Essential Appliances
Write down the appliances you want to run during a grid power outage. Think about your fridge, lights, Wi-Fi, and medical devices. You do not need to include every device in your home.
Check Appliance Wattage and Usage
For each appliance, find the wattage (usually on a label). Multiply the wattage by the number of hours you use it each day.
For example, a 100-watt light used for 5 hours uses 0.5 kWh (100 × 5 ÷ 1000).
Add Up Your Loads
Add the kWh for all your chosen appliances. This total shows how much energy you need from your home battery during an outage.
Decide on Backup Hours
Choose how long you want backup power. Some people want 4–8 hours for short outages. Others want overnight or even several days if they live off-grid.
Tip: Focus on your most important appliances first. You can add more later if you need more backup power.
You need to know how big your battery should be. The right size gives you enough backup power without wasting money. Use these steps to find the best size for your home battery storage systems:
Start with a Load Analysis
List the devices you want to run during an outage. Do not assume all devices run at full power all the time.
Calculate Daily Energy Consumption
Use your electricity bill or your appliance list to find your daily kWh use.
Formula:
Watts × Hours per day ÷ 1000 = kWh per day
Set Backup Power Goals
Decide how many hours you want your battery to last. For example, you may want 8 hours of backup power.
Adjust for Depth of Discharge (DoD)
Batteries do not use all their energy. The depth of discharge shows how much you can use. For example, if your battery has an 80% DoD, you can use 80% of its total energy.
Consider Inverter Efficiency
Inverters change battery power into usable electricity. They are not 100% efficient. Most inverters are about 90% efficient.
Use the Battery Capacity Formula
Required battery capacity = Total backup load (kWh) ÷ Depth of Discharge ÷ Inverter efficiency
For example, if you need 16 kWh for 8 hours, with 80% DoD and 90% inverter efficiency:
16 ÷ 0.80 ÷ 0.90 = 22.2 kWh
You need a 22 kWh battery to cover your needs.
Step | Example Value | Explanation |
|---|---|---|
Total backup load (kWh) | 16 | Energy needed for chosen appliances |
Depth of Discharge (DoD) | 80% (0.80) | Usable part of battery |
Inverter Efficiency | 90% (0.90) | Power lost in conversion |
Required Battery Capacity | 22.2 kWh | Size needed for 8 hours of backup power |
Note: Always check that your battery matches your inverter size and your solar panel system. This helps your home battery storage systems work well together.
