Overdependence on third party vendors in countries run by hostile governments is not good. What the Sol-Ark series of inverters need is a local web server that presents a status page to computers on the LAN (that updates more regularly than the 10min interval of the app they have now) so users can see what the inverter or inverters are doing. For those that want a cloud/internet app, an app developed by American coders and hosted on American servers. The latest app from Chengdu E-Linter wants access to your call history and contacts and camera and all kinds of shit that it does not and should not need.
To address the issues DavidPoz has had with his Sol-Ark, it is a simple matter of load balancing.
