I am using an Eastman ES6KW-HY-P inverter with a Dyness lithium battery, and I am experiencing a problem with the inverter’s behavior in SBU mode during nighttime operation.
-
At night, the inverter initially runs in a sort of hybrid mode, where the battery supplies the load while the grid remains ready to support.
-
However, this behavior lasts for only about 10 minutes, after which the inverter automatically switches to battery-only mode, and the grid stops supporting the load.
-
In case of overload at night, instead of falling back to the grid, the system shuts down completely.
-
I have already enabled the Overload Bypass function on the inverter.
-
During the daytime, the hybrid mode works correctly with the same grid connection, so the issue happens only at night when using the battery.
I would like to request a solution that allows the inverter to remain in Hybrid mode at night, instead of
