Hello William, I had not seen the video prior to your posting. I totally agree that a one day install of a complete battery back-up retro-fit is completely unrealistic. Perhaps 4 to 7 days, depending on the complexity and size of the retro-fit. Yes, one day might suffice to install and wire just

Hi Chris, I think this would be a product mainly used in existing grid-tied retrofits. If there is an existing grid-tied only inverter, you could route the DC conductors through this transfer switch first giving the homeowner a grid-tied or off-grid option if the grid was down. You'd still need

Chris, My first take on it is that it's been developed for those who already have batteryless GT systems and now want to add backup capability. The Tesla Powerwall has generated plenty of buzz, even though it's still expensive and unavailable, for battery backup.

Chris: The market Morningstar is going for is the customers with non-battery, grid-tie only inverters. If you then add the Morningstar product and a whole lot of other items and a lot of labor, you can have battery backup. If you already have a complete GTBB system, such as you describe

We've been using ac coupling with Magnum's when adding backup to a grid-tied system. The switchover is automatic and fast. With the Magnums, there is need for a charge controller, but the installation and wiring does take more than a day (meow). Why would anyone want a manual transfer switch
