How to Size a Solar Battery Backup System for Your Home
To size a solar battery backup system for home, start by listing the appliances you want to run during outages, like lights, fans, fridge, Wi-Fi, or TV. Next, check each device’s wattage and estimate how many hours you’ll use them daily. Add everything up to get your total daily energy use in kWh.
Then decide how many backup hours you need, such as 6, 8, or 12 hours. For example, if your essentials use 2 kWh per day and you want 12 hours of backup, you’ll need about a 1–1.5 kWh battery, adding extra for losses. This helps you choose the right solar battery backup system for home without overspending.

Why You Need a Home Solar Battery Backup System
A home solar battery backup system keeps your lights on when the grid goes down. Instead of sitting in the dark during outages, you can run essentials like fans, Wi-Fi, lights, and even your fridge with stored solar power.
It also helps cut electricity bills by storing excess solar energy for night use, so you buy less power from the grid. Over time, this means real savings and better use of your rooftop solar system.
Most importantly, it gives you energy independence while being an eco-friendly choice. For homes in areas with frequent power cuts, like many parts of India and even some regions in the US, a solar battery backup brings peace of mind every day.
