KH10 Grid Import during ForceDischarge period after FD SoC% reached

suti · Tue Jul 21, 2026 12:08 am

very strange. i do not have "After Discharging Cut-off" option in the app..."

app: Android 2.2.18
inverter master: 1.60 -- no red dot to suggest i can update in app
inverter manager: 1.58 -- no red dot to suggest i can update in app

KH8 if that makes any difference.

At the end it says "during 18:01-20:05, the battery discharges to your home and grid until it reaches 19% SOC, then switches to ." ie there is a big black after "switches to..."

huh, i guess that's your inverter firmware.... probably too old to support the feature

did they take out the self-update feature from the app ? i can't see the screen anymore...

I've emailed my installer to upgrade the BMS and inverter software. I am pretty sure i was able to update the inverter software through the app a few months ago. At the moment It does not say whether there is a later version available. Maybe KH8 is stuck on older software.

will report back once i get updated

KH series should be able to update to master 1.70, manager 1.66 which hopefully will give you the ability to set the mode on reaching target SoC.
The user's ability to upgrade inverter firmware does seem to have been pulled at the moment although the ability to upgrade the logger remains (IIRC the user has never been able. to upgrade battery firmware)
