2000: Sandia Labs Creates Solar Inverter to Enhance Safety of Systems

Sandia National Laboratories develops a new inverter for solar electric systems that will increase the safety of the systems during a power outage. Inverters convert the direct current (DC) electrical output from solar systems into alternating current (AC), the standard current for household wiring and for the power lines that supply electricity to homes.
