A few things to know when installing a home battery storage

Solar panels are a great way to generate electricity during the day, but they don't work at night when you need energy the most. Installing a battery can help you make the most of the energy your panels produce. Without a battery, you will have to rely on the national grid for electricity at night, which can be expensive. However, with a battery, you can store any excess energy generated during the day and use it at night when you need it most. This will help you reduce your reliance on the grid and save money on your electricity bills.
