Protection functions:

  • overload
  • deep discharge
  • battery undervoltage
  • current reflow into the module

Protection from application errors:

  • short-circuit/reverse polarity at solar module
  • short-circuit at consumer output (excessive consumption)
  • reverse polarity at battery
  • overcurrent at solar module
  • overtemperature
  • overvoltage at consumer output
  • wrong connection order

The default battery type can only be adjusted with additional equipment (Steca PA PR100).
The PRS-series's default battery type is lead-acid (liquid).
