Good day all,
I have a newly installed Deye Hybrid Inverter. (Which I am led to believe is the same as Sunsynk and Fusion)
The system is connected to the grid with a CT, the CT is currently pointing towards the inverter. When I point it towards the Grid, the inverter gets negative values towards the grid (Which I believe means it is "selling" to the grid). The inverter however is set on "zero export to CT"
Currently I have 2 issues:
1. The prepaid meter trips momentarily every now and again, it happens mostly around 1 pm and 4 pm. It will trip for about 20 seconds then come back up, it will do this 3 to 4 times in a row. I cannot point to a specific scenario where it trips, ie. High load, Low load, No load. It happens completely random.
2. Because it is a Bi-Directional inverter (Or so I believe) I have my High Load items connected to the "Grid" side of the inverter and my Low load stuff to "Load". When the Grid drops due to the trip in the prepaid meter, my high load items trip with it. Shouldn't these items stay on? At that point in time there are more than enough power coming from the panels and should be able to keep my loads running?
I am attaching a rough diagram of how it is currently connected. The Grid and "Load" neutrals are split and running separately. Earths are all connected together.
Hoping someone out there can give me some answers.
