November 7, 20241 yr Hi to all, This is my first post although I have had a 5.1 kW Deye hybrid inverter and a 5 kW.hr Dyness battery for about 3 years. After my first year I added 6.3 kW solar panels on my roof. About 2 months ago I started reverse feeding my excess solar back to the grid. All well and good. I have a question about F20Tz_Dc_OverCurr_Fault that I get once a day. My battery has a 50A Max Charge and 50A Max Discharge limit. However, I have discovered that the battery charge current limit (red line) changes as the battery nears fully charged. The battery charge current limit line below steps down as the battery nears fully charged. What happens each day is that the charging current gets very close to this limit and there is an overstepping of this limit. Today, the trip occurred at 09h35. The screenshot shows 09h33 where the current limit is 20A and the battery current is 19.99A. I am at a loss to explain this but I get a trip most days around about this time of the day and it always happens within an hour or two of the this part of the day. Are there any suggestions as to how to avoid this. As far as I can see, there are no settings on the inverter that can be tweaked.
