One significant change involves ganged devices, particularly when isolating inverter systems. Previously, each inverter required separate isolation, which could be cumbersome. Now, if you have more than two Inverter Energy Systems (IESs) connected to a switchboard and those IESs are on a ganged switch, they are treated as one device. This means you only need one main switch for the en... https://www.cleantechcontrols.com.au/ganged-devices/
