This webinar features the New New TriStar MPPT 600V Controller With DC Transfer Switch and its application to retrofit existing grid-tied solar systems with battery backup. Many owners of residential and light commercial solar systems are unaware that when there is a grid outage, their PV system will not provide power. Their PV array will be left stranded. Fortunately Morningstar’s DC coupled solution offers a clean, simple, affordable way to provide battery backup power for critical lights and appliances in the event of a grid failure. Viewers will see how this solution compares to other options such as AC coupling and generator backup.
