There is a shortcoming with grid-tied photovoltaic (PV) energy systems of which owners are often unaware until an emergency: Although grid-tied systems can save money and earn their owners incentives while the sun is shining and the utility power grid is up, they must disconnect when the grid is down during an outage, leaving unused solar electricity sitting on the roof. As a safety feature within generic grid-tied systems, when the grid is down, users can neither sell energy back to the utility, nor supply their homes or businesses with power per the UL-1741 safety requirement. Luckily, there is an upgrade for these types of systems called AC coupling that enables one to store energy for use during power outages and emergencies. AC coupling added to a simple grid-tied system converts it to a grid-interactive or Grid/Hybrid type system, providing grid-tied savings when the grid is up and off-grid independence and security when it is down or compromised….
