The open-circuit voltage (Uoc or Voc) of this powerful module is 31.2 V.
Make sure that the charge controller has sufficient dielectric strength!
VOTRONIC SR series charge controllers are unsuitable for this module, as they are only designed for a max. no-load voltage of 28 volts.
MPP series VOTRONIC controllers accept up to max. 50 V module open-circuit voltage and can be used with the MARE FLEX 155 without issue.
