All of the grid tied solar systems are able to conform to the IEEE 1547 standard. Amongst the particulars are a 300 second reconnection time if there's an interrupted grid to protect utility workers. Most (all?) USA utilities mandate this standard. Some battery systems, like the Tesla Powerwall include a contactor that allow their microgrid battery systems to conform to the standard without a loss of power to the site they power. https://standards.ieee.org/standard/1547-2018.html https://standards.ieee.org/standard/1547-2018.html
