# Unfortunately Kostal has introduced the third version of interface.
# This time it is XML
# This is for Kostal_Piko_MP_plus and StecaGrid coolcept (single phase inverter)
# In fact Kostal is not developing own single phase inverter anymore but is souring them from Steca
# If you have the chance to test this module for three phase inverter from Kostal (Plenticore) or Steca (coocept3 or coolcept XL) let us know if it works
