[Bug]: Parallel system power levels incorrect on individual inverters #863

Closed Cybgak closed 1 week ago

Cybgak commented 5 months ago

Describe the bug

In a parallel system when you send the remotecontrol values to the master inverter it also applies them to the slave inverter. The problem is the power limit values allowed are based on the values for a single inverter (15000W) however when the master inverter receives the value it divides it over the available inverters so for instance with two inverters each one is limited to 7500W.

Do you use solax_export_control_user_limit or remotecontrol_export_limit ?

Cybgak commented 5 months ago

Do you use solax_export_control_user_limit or remotecontrol_export_limit ?

solax_export_control_user_limit is set to 12000W on both inverters I think remotecontrol_export_limit has been disabled because it wasn't working properly.

maybe help #858

wills106 commented 2 weeks ago

Did #858 help? Can this be closed down?

Cybgak commented 1 week ago

I'm not sure the setting suggested in #858 is required any more as I seem to be able to set the remote control limits to 30,000 (2x15000) anyway now which is what I needed.
