Went ahead with the suppliers suggested method, by not using the ATS port, as the delay is around 90 seconds and they stated that it is not that reliable. The inverter is performing good so far. Over 120 days now running, and not one single issue.

Hi Talia, Thanks for the reply. I have checked for those settings, but they are not included in the settings menu. I have a seperate DB box with an indicator light and a 10A relay. Here's the manual, the steps are quite clear, but it doesn't work the way they state it should. https://www.pvpower.co.za/wp-content/uploads/2025/04/SUN-3.6-6K-OG01LP1-EU-AM2-OG6K_Deye_6kw_off-grid_User-Manual.pdf

Greetings to all, I've just gotten my solar installation up and running using the new(?) Deye SUN-6K-OG01LP1-EU-AM2 off-grid inverter. According to the manual from Deye, the ATS240 port can be used to control an external Earth-Neutral bonding relay, by enabling Gen Charge and Gen Signal and with the dipper switch of ATS all on. Currently the output stays at 230v and does not switch off when grid is connected. I've tried numerous settings and keeps reading 230v on the ATS. With dippers off theres no power whether on- or off-grid. Anyone here that can shed some light on this, as I've read quite a few posts about similar issues where Island Mode should be enables, but it's not available on this model. Should I just go for a NC relay connected to the grid that bonds the E-N once power is out? Also, some Sunsynk/Deye manuals show on the diagrams that no PE should be connected to the inverter when E-N bonding.
