SolarTouch 4+

I work in IT so I’ll comment on both the usability and technical aspects of this app as I’ve been using it for over a week on daily basis to monitor my PV9000 inverter.

The app is inconsistent when connecting locally via BT vs Wi-Fi. Eg on BT the Gen/Heavy load is categorized separately in the animated diagram section but on Wi-Fi the Gen/heavy load is shown combined with the light load. So it’s basically a downgrade as you now has less data points for reference. It would be fine if BT range was great but my 2022 model PV9000 unit BT range drops off after about 10-12 feet which is baffling as my other Bluetooth devices work in over 20-25 feet range. So BT option for the app is basically gimped unless you’re standing right in front of the unit. So the only option is to use Wi-Fi.

Next, the charts. They’re horrendous. There should be more options like bar chars and pie charts. So far it seems like a students final year project as there is a single barebones chart option. The color choices for the different chart items are also terrible.

The Wi-Fi data on app also has minor bugs eg in some areas it will report PV generation as 0 until our system has generated over 1kW. It should be updated in smaller intervals more accurately.

I’ll have more thoughts but so far there is massive room for improvement in the app. I hope Solar max gives it more attention rather than leaving the app as a basic placeholder as an obligation.

Please fix bugs!
