Add support for whole apsystems ez1 series (#123356)

* Add support for whole apsystems ez1 series by configuring the max_output at setup to match the value by the inverter

* Check Max output for apsystems on startup, not setup

* Move max output check into coordinator

* Raise UpdateFailed on error in apsystems
