Retrofitting Grid-tied Systems with Battery Backup 3 Minute Video

Most residential and light commercial grid-tied solar systems need utility power to operate, so they won’t function during a grid outage. This animated video illustrates how Morningstar’s TriStar MPPT 600V Controller with DC Transfer Switch can be used with other components to charge battery systems to provide backup power to run your critical loads when the grid goes down. This is a clean, economical, scalable solution that does not compromise your solar system’s efficiency.
