What is the third column, battery voltage/dc bus? Noted the log is where the more recent event is at the top. If the third column is battery voltage/dc bus, it drops to 14.7V, then up to 43.7V. This is a result of the controller attempting to supply the dc bus voltage when the voltage drops and switches the algorithm looking for max peak power point.Found it !
Here is one of the events shutting down at far from max PV power...

"This could be the result of a load switching on drawing down battery/dc bus voltage. I would be checking wiring and connections first, using the various loads you have on the inverter and monitor battery and dc bus voltage. It could be internal to the unit such as a loose connection."The third column is the current from the PV
Is it possible to increase the interval between samples? We dont really know what happens after the last sample...the indication is of course that the power and current goes up but...
There's an indicator. If it stays stable through the next couple days I think you've found the culprit.No disconnect today
