Page 7 of SmartSolar 150/70 installation manual says the maximum solar panels is 5x24 volts panels which makes 120 volts and this value stands below the maximum input regulator voltage 150 Volt, but if you consider Voc voltage of these PV panels is above this value, That is, 5 panels x Voc surpasses considerabily 150 volts. The question is, What is the voltage reference that we have to consider for the SmartSolat regulator?.
