Its horses for courses I suppose in this debate.
I started out with the SolarMan app but found that to be too clunky and limited with data availability. Was looking for something more real-time to manage my system.
Did a search on this forum and the first one that came up was Solar Assistant. Did the research and found it to be what I needed. Ordered online and the kit was delivered within a day as advertised. Took me all of 15min to install the Pi and get it running and have never looked back.
I was upgraded to the beta version which included the Power Management tab being activated for my Deye inverter and that allowed me more control over the System Work Mode feature remotely especially when loadshedding struck again.
Support has been good too.
I have subsequently looked at the ICC software but am very happy to be with Solar Assistant.
