The Span electrical panel replaces your current panel and prepares your home for a much-needed electrical upgrade. Once installed, you can control every circuit in your home from your smartphone. Your standard electrical panel was not made to support solar panels, electric car charging, or home batteries. The Span electrical panel allows you to visualize what is using energy the most and where your energy is coming from. It helps you to monitor your energy output and even manage it when you are away from home. You can also pair Span with a home backup battery to manage your home in a power outage.
