How Can I chose correct model of Rapid shutdown Switches for my solar system?

For example: The open-circuit voltage of each PV Panel is 39V, Aswich rapid shut down switches rated voltage is 1000V, so each route of MPPT max can connect PV panel quantity is 1000/39/1.15=22 pcs. Such as your Solar Project has 162 pcs PV panel, so 162/22=8 sets of rapid shut down switches with 2 poles (ERS-2) Or 162/22/2=4 sets of rapid shut down switches with 4 poles (ERS-4) Or 162/22/4=2 sets of rapid shut down switches with 8 poles (ERS-8) The Aswich rapid shutdown Current must be higher t
