PV Master

The App is not the problem -it works ok. The problem is all the permissions it had access to. Why does the app need access to control the flashlight, volume and audio, camera, disable screen lock, pair with other bluetooth devices retrieve other running apps, download files without notification and so on. Looks to me like it is quite a detailed spyware package! !

I had countless problems with the app. Why 4 stars. Firstly the service from the Goodwe support team was excellent after logging a support call with them. I experienced similar problems other users reported, BUT the problem seems to be backward compatibility between the app and the firmware version of the inverter. Goodwe updated my inverter from firmware v1717 to 2424. Now the app is responsive, shows all options and saves the data after making changes. I will monitor and update the post.

better than nothing? GoodWe implemented their data connections and transmissions in a weird way. plus there is no cyber security function: i.e. change default passwords "goodwe2010" or "admin/admin". Additionally some of the functions of this app aren't documented. If you have options for buying another inverter/pv make then I would recommend to do so.
