Solar Guardian 4+

The EPEVER app UI was better. This is very difficult to set up and use for local Wi-Fi. Create an account, go offline, find your device. You finally get in and the real time data doesn’t refresh, it’s all text based. Looks like an early 2000’s app.

I’m happy with the performance of my Epever solar charge controller but monitoring leaves a lot to be desired. Considering switching to Victron just because the monitoring is way better.

I have an Epever Tracer AN 30A charge controller and I have been using the RS435 port wire-connected to a Windows computer to program/monitor it. Not very convenient and the app is not very user friendly. Got the Bluetooth adapter, downloaded this app for my iPhone and easily got it connected. No registration required for Bluetooth (“Local Connection “). The app is excellent, with clear displays for real-time data, and several other displays for the settings. The only odd thing is that when the app first starts up the “current setting” may not be correct. To make sure you have the correct current setting you need to hit the “Read” button at the bottom of the page. Why doesn’t this happen automatically when the app connects to the Tracer? It was also like this on the Windows app. To change settings you type in the new values in the current setting field and then hit the “Apply” button at the bottom of the page. There is also a “Reset” button. Not sure what this will do.

Seems like after a couple of apps and attempt they finally got a good functional app for Bluetooth connection. Speed of connection is much faster and the range has even seemed to increase as I was not able to connect from another room previously. Nice work.
