Yes, of course. Pretty much any SCC instructs you to connect battery and power up before connecting PV (and the reverse for depowering).I do recall in a manual that it said to connect the batteries before connecting solar. I would imagine reverse for a disconnect which is why I assume I did not suffer a similar failure.
Digging through my papers, if i find it ill add
Powering or depowering with an incorrect sequence certainly has nothing to do with the issue I experienced.
Others have indicated that moving out of charge sequence may be related - as long as in the same Boost Charge Stage, for example, certain new settings are ignored.
I never got my charger past Boost, so if that was the cause of my issue, connecting to a power supply and driving to voltages well past Boost may have done the trick (I did not have the foresight to check that it moved out of Boost into Float, but it should have since I drove voltages higher than Boost).
