Span Smart Panel
What Is SPAN?
SPAN turns your electrical panel into a smart system you control from your phone — giving you full circuit control, outage protection, and ongoing improvements with software updates. Unlike a traditional panel that stays the same forever, SPAN keeps getting better with every update.
