Works pretty well. The trend graphs only work while you have the graph on the screen. If you move away from that screen even for a moment, the data is lost and it restarts. Also: no dark mode. The screen is mostly white which is both annoying and wastes the phone battery. EDITED: The 45 days applies to the History feature. I'm looking for minute-to-minute current/power data in the Trends feature.

Hello, The SmartSolar 75|15 has a 30 day cycle history and 45 days of trend data which is stored inside the device. If this is not the case in your SmartSolar, then it might help to press Clear History in the trend screen. The 45 day trends will be fetched each time that connection is made, so also after switching to another app.

Update removed the displayed quantities being tracked by the app. Every time you switch away from the app, then go back in to look at trends, you have to choose again which values to display... It was nice to just pull up the screen and not have to fool with it. Multiplus 24/3000 voltage readings are NOT accurate, compared to other Victron equipment and my Fluke 87. LiFePo needs an accurate charger. Also, the Multiplus OVERSHOOTS the configured voltage by over 0.3 volts on EVERY charge cycle.

The only serious problem I have is that if you set a name in the product information page, it is not saved. That's got to be a bug. As soon as you exit back it comes back to what it was originally which is a combination of the product type and that sucks if you have more than one of something. Both BatteryProtect 65 and SmartSolar MPPT 75/15 connecting over BLE exhibit this. PLEASE FIX.

Hello, Thank you for reporting this. We are able to reproduce the issue and are investigating what can be done about this issue. To get the correct name in the mean time, the device has to be forgotten/remove in the Android Bluetooth menu (after the name change) and paired again.
