Choosing the Right Home Battery

Capacity and Power

To pick the right home battery, you need to know your energy use. Make a list of things you want to power if the lights go out. Write down how much power each thing uses and how long you want it to run. Use this formula:
Daily kWh = (Wattage × Hours Used Per Day) ÷ 1000
Add up the energy for all your important things. Multiply this by the hours you want backup power. This tells you how much energy your battery system needs.

You also need to think about how well your system works and how much battery you can use. For example, if you use 10 kWh a day, your battery is 90% efficient, and you use 80% of it, you need about 14 kWh of storage. Always add 20% more for changes in weather or surprise needs. If you have a 1000-watt load for 5 hours, you need 5000 Wh of storage. Divide this by each battery’s size to see how many you need. Make sure your inverter can give enough power too.

Tip: Always get a little more battery than you think you need. This helps your home battery work well during long blackouts.

Efficiency and Lifespan

You want your battery to last a long time and work well every day. Pick batteries that are very efficient, so you do not lose much energy. LiFePO4 batteries are over 90% efficient and last more than 10 years. The number of charge cycles tells you how many times you can use and recharge the battery before it gets weaker. Batteries with more cycles are a better deal over time.

If your battery lasts longer, you do not have to buy new ones often. This saves money and makes less trash. Always check the warranty and how many cycles the battery has. Pick a battery that fits your daily needs and will last for years.
