azein Posted October 7, 2016 Share Posted October 7, 2016 Is there anyway to simulate AC Coupled off-grid systems: Grid-tied inverter + offgrid battery inverter? Link to comment Share on other sites More sharing options...
André Mermoud Posted October 14, 2016 Share Posted October 14, 2016 This is not yet implemented.See our FAQ Can I include a battery in a Grid-connected system ? Link to comment Share on other sites More sharing options...
aaronrodg Posted November 10, 2016 Share Posted November 10, 2016 I 'discovered' this a few months ago at a conference. I know a lot of people would like the ability to use their solar array in the event of a power outage. There are currently 3 'off-grid capable' inverters that can sync to a grid-tie inverter and trick it into thinking the grid is back. These inverters then couple with the grid-tie inverter and regulate it's output by sending excess energy to the battery or dump load. If the battery is full they increase frequency to 60.6Hz which won't effect anything being powered but will cause the grid-tie inverter to trip off-line.The AWESOME thing about AC coupling is that it can be used with virtually ANY grid-tie system... Micro-inverters, SMA, Fronius... doesn't matter. Link to comment Share on other sites More sharing options...
