Solaredge entities disabled - why?

Hi all, I am trying to build up mu HA at very low speed due my poor knowledge of the matter. Among the various questions I have, could you clarify the following:

  1. My Solaredge inverter shows 21 entities but only 2 are enabled, the other 19 are disabled. Is it possible to unlock them ?
  2. I have approx 10 add-ons: from Registry, how can I understand if they are running fine ?

If the really are marked DISABLED, it is a question of seconds to get them ENABLED.

Click on the entity, click on settings and click enable.
