I put in 0°C and Voc warns it is very close to 150 maximum at 148.44 volts.
If you put in lower, the calculator may have said to go parallel because Voc rises as temperature drops.

Alternative controller is MidNite Solar 200 (Vmax 200 volts) and then you are pushing $700.

Shop around

Voltage will tend to be closer to Vmp while in use. I would probably chance it with the lower cost Tristar. Could always cover one panel in winter.
