with a Classic 250 would you guys do six in series or not? (HyperVoc marginal)

From an electronics point of view it is always better to keep the In and Out voltage closer together. I usually recommend 1 nominal voltage above battery for an MPPT controller. Of course long wire runs can push us to use higher voltages when needed.

Outback produced a graph of input voltage vs battery voltage showing the efficiency of the MX60 at various voltages. From this I would series three 17.6v panels for 53v in to 24v out as it was an efficient setting. Now it's four series to 70v in via the 150.
Is there a similar graph for the Classics?
