Rotor packing (optimization) set
Rotor packing (optimization) set

Rotor packing may be needed for any of the following reasons:

  • To trim runaway voltages lower
  • To manually optimize PMA directly connected to battery banks
  • To reduce hysteresis losses in some MPPT applications

The spare flat nut is provided so that the 1st washer (if needed) sits flat and does not rock on the end of the protruding thread.

A larger 1st position packing washer (marked red) may be supplied instead of the flat nut shown.
