Hi,
After installation, I found that my solar sold to the grid and was purchased back at the same time. The smart meter shows as follows It seems each time, energy is discharged from the battery, sold to the grid, and purchased back for use.
I asked the installer, but he said no issue on his side, but I suspected something was wrong here, even the inverter said pull from the grid a small amount.
Thanks

Sounds like you have a problem, or the settings are wrong.
You haven't accidentally set up an export schedule?

My installation had the wires wrong, and it reported an export when it was actually importing and visa versa. This made the system go crazy.

Thank you, Mark, for your response. I found the problem:

• My hot water heater is on control load 1, and when it runs, the inverter detects that the house is using energy and discharges the battery, and sells the electricity to the grid.

• At the same time, the hot water draws electricity from the control load 1.

Now I set the battery do not discharge during the time the water heater runs, 10 pm-1 am
