-That is the value you have to fill in case you want to operate the inverter without a active power limit.
-If the value is 65535 or -1 after another reboot the value will be set automatically to "100" and in the drop-down menu "relative in percent persistent" will be set. Of course you can do this also by your self.

-The AhoyDTU subscribes on three topics `<TOPIC>/ctrl/#`, `<TOPIC>/setup` and `<TOPIC>/status`.
+The AhoyDTU subscribes on following topics:

+- `<TOPIC>/ctrl/limit/<INVERTER_ID>`
+- `<TOPIC>/ctrl/restart/<INVERTER_ID>`
+- `<TOPIC>/setup/set_time`
 
 👆 `<TOPIC>` can be set on setup page, default is `inverter`.
 
 👆 `<INVERTER_ID>` is the number of the specific inverter in the setup page.
