Deye Hybrid Neutral bonding when off grid.

Question

As I have researched I have discovered that the Deye neutral needs to be bonded to earth to prevent a floating neutral, when the inverter is off grid. The manual doesn't discuss the topic. Does anyone know if one of the auxiliary terminals can be used to drive a relay to earth the neutral? The auxiliary terminal is 1 -12. 1 and 2 are for the battery temperature probe and 3 and 4 are for the CT. I have searched and found no other information. Deye has as yet not replied to my query. Perhaps they are still on holiday. If someone can help it would be greatly appreciated.

Thank you Vassen. If I can't get a signal from the Deye I will have to use your suggestion. I am concerned that the grid may be up but the Deye off grid as the PV's and or batteries have enough power to keep off grid. In this situation the Deye Inverter will disconnect from the grid which will allow for a floating earth. I am making assumptions now. Regards

Hi Vassen, I didn't answer why I have chosen a Deye. There are two reasons. I live in Scottburgh where the temperatures can easily reach 40C and I wanted an inverter with a fan. Secondly I liked the smart power feature. I will investigate the Sunsynk as I haven't put in my order yet. Regards

What size deye are you looking at. I have the 8kw sunsynk and it has a fan. I think only the 5kw and 3.6kw sunsynk inverters do not have fans. Very happy with going for the sunsynk over the Deye.

Hi All, I have checked out the Sunsynk and it looks fine. I will have an East West configuration so the 2 MPPTs was essential. I was concerned about the two reports that the Deye cause a buzz on some equipment. Thank you all for your input.

I intend to put a 5kw inverter in. The installation manual of the 5kw shows a fan. I will check this out. Thank you for the comments

Hi Achmat, I intend to buy a 5kw system. I checked the manual of the Sunsynk and the 5kw shows a fan. After the comments I am most likely going to go the Sunsynk route.

So the kettle draws 2 kW for a couple of minutes, will draw from the grid, look at loads that are used for a while like geyser, washing machine, tumble dryer, dishwasher, air cons, plus then you need over 10 kWp of panels, do you really need all that
