User Reviews

EMA App is valued for showing current production and per-panel output with a clear data view, but users report reliability and UX problems. Recurrent issues include night mode not persisting, delayed or hidden data, frequent offline outages, and removal/degradation of per-panel data. Users also want better data history/export options. Overall, core monitoring is possible, but stability and feature regressions significantly hamper the experience.
Pros
  • Shows current production and per-panel output with monthly data snapshots.
  • Data is presented in an easy-to-understand, attractive format.
  • Includes equipment health/warranty information in the data view.
  • Provides a snapshot of previous months' production for trend awareness.
Cons
  • Settings like night mode don’t stay saved or sync with the device; you must reapply them each time.
  • Data is delayed and not real-time; there can be 10-15 minute lag and display issues requiring interaction to show data.
  • The app frequently goes offline or is unreliable, often forcing users to check information on the website.
  • Removal or degradation of per-panel/module data undermines core monitoring capabilities.
  • Limited data history and export options (no CSV export; restricted time range) hinder long-term analysis.

I see there was an update 2 weeks ago and that’s when it quit working. Called customer support and they said it was being talked by the reps but that’s it . No fix available.

I had my panels for three years. What do each of the different screens mean. Need to be clearer and not make me guess.
