Choosing the correct battery for your residential solar system can be confusing. There are so many different types of batteries and so many features to consider! This article will help you understand what factors to consider when choosing this component for your home.

The most important part of your off-grid solar system is your battery bank. It’s the powerhouse that stores all of your solar energy for use at night. It is essential to understand what type of battery best fits your needs and how to size a battery bank so it doesn’t run out during the day or night.


Most people choose to invest in a battery that will provide enough energy requirements for at least one day.  Having at least one full day of power will ensure electricity even when there is little or no sunlight. If you have an auto-starting generator, the severity of this problem can be reduced. An auto-starting generator for solar systems helps provide backup power when there is not enough sun, and the battery bank is low.

We recommend choosing the largest and most efficient battery you can afford for your solar system during the initial installation. If you’re unsure of how much power you need, it’s better to get a larger one that you can add to add at a later date should your needs change.


Hopefully, the tips we’ve outlined in this article have given you an understanding of the importance of choosing the correct battery for your home solar system. Given the importance of this decision it is always best, where possible, to get professional advice on selecting the appropriate battery.
