We’ll ask about items such as refrigeration, internet, lighting, medical equipment and cooling, then discuss what a proposed system is designed to support. Whole-home backup should never be assumed from a battery count alone.
If you have solar panels already, compatibility with the existing inverter, electrical equipment and ownership arrangement matters. If you do not have solar, a battery-only installation may still be worth discussing. How it charges and performs depends on the equipment and available program.
For a new installation, see how solar and battery storage can be planned together. If your panels are already installed, start with our existing solar guide.
