I played about with that syncing business of inverters. Yes, Poida's code works well to sync two sine wave inverters with no load on them. The trouble is when it comes to power sharing. As it was the inverters (or an inverter and a inverter type genny) would not share power evenly unless there was some kind of current feedback in play. I gave up then, it got too complicated for my limited knowledge. I suppose the idea of using a single nano driving different inverters should work but involves creating a reliable driving signal connection between them. Having more than one inverter works well for me if I run them independently. The house wiring for the lights and for GPO/power is separate, one inverter for each. A spare inverter could be put in service to power my shed & workshop if I wanted that.
