First: How I can plot or save the voltages related to the taps of the regulator transformers? I need this numbers to know how my circuit will be influenced (or not) by the PVsystems that I add and I want to know how tap the regulator transformer is connected.

Second: Related to this question, now about the PVsystem, I want to know how the frequency inversor will act on the painel when he's connect to circuit, if it is possible to storage the charge in a moment of the day and than after this discharge in another period of time, it's possible doing this with software?

P.S: vvc_curve1 how this command works?
