In the Sunsynk Elite Model, there is an automatic Earth Neutral Bond for when the Grid suffers an outage. The internal Normally Open EN Bond Relay is triggered when the ATS Port goes ‘Live’ (230Vac) when the Grid is lost.
However, for the ATS to go ‘Live’ Signal Island Mode must be enabled. Also, the ATS Port Switches must be in the ‘ON’ position. Below are screenshots of the ATS Switch information from the Sunsynk Elite User Manual on how to enable or disable the 230Vac ATS
