In the new mySolarApp version we added a diagnostic mode to make a data capture every minute for a max duration of four hours. In the capture we pull out the battery voltages, charger currents and panel currents. This data is presented in a graph where you can switch on or off the items that you want to study.
We support now 4 Inverters and 4 chargers (all connected to the Outback Mate).
Send the log file (xml formatted) to your installer to ask for advice. The installer can download the free Viewer to see the same graphs as the mySolarApp program provides to you.
