With all the concerns around monitoring i must recommend the Centurion Solar "solar management hub". its on a Raspberry pi which you connect to the inverter with a suitable cable and it just works. you have a mobile app, desktop webview, can download all the data via csv files and as close a you can to real time updates. app also has good anlaysis graphs built in. support is real good installed it on my sunsync 8kw around 1 year ago as i was frustrated with the sunsync app. you do need a subscription but its nominal around R500 for the year. what a pleasure
