Home battery backup can only cover roughly a day of storage

Evidence

To take advantage of the vast potential of renewable energy requires development of energy storage technologies (Huggins, 2010). Home storage systems depend on rechargeable batteries to provide a backup electricity supply. They can do so for about 24 hours. The new generation of batteries will have greater storage capacity but battery energy storage has limitations. — Albert Bandura, Moral Disengagement, 2920
