I recently updated my Zendure 2400 AC from firmware version 1.0.15 to 1.0.19.
Since the update, I have noticed a significant change in charging behavior when the battery is charging from solar power. When clouds pass and the solar input drops, the charging power now takes around 40 seconds to decrease from 2400 W to 50 W (for example). In firmware versions 1.0.1 - 1.0.15 this adjustment happened within just a few seconds.
This change was not mentioned in the firmware release notes....
Because of this delay, the system imports far too much energy from the grid, which makes charging from solar effectively unusable. Around 1 kWh import extra each day.
I tested the difference with a Zendure 2400 AC FW 1.0.1 and 1.0.19;
