K series unable to Force Charge/Discharge

[williamjeccles]

My setup is two KH10.5 wired in parallel (master/slave enabled) and connected to full stacks of HV2600 8* batteries per inverter. The inverter and batteries are all on the very latest firmware using the latest version of HA and the modbus plugin.

If I set a force discharge/charge period via the Fox Cloud web UI the inverters are able to discharge/charge without issue, no fighting or flapping.

However, I can reproduce the issue if I use HA via the plugin to set the inverters into Force Charge workmode or Force Discharge workmode the inverters start flapping and fighting as per the video example.

I have a suspicion that the kW limit is causing the issue for systems that are parallel. Almost like its telling the systems to discharge at say 7kW total instead of per inverter.

I would like to bypass the UI limit as I believe this might be causing the inverters to flap/fight. So I'm happy to test and rule out this suspicion if someone could point me which file and line I should comment or adjust to test out my theory.

I believe if I could set the force discharge limit to 21kW then it would allow both inverters to max out their charge/discharge amount instead of fight. It's not a perfect fix but at least it would unblock and validate my current belief.
