• Active Energy Towards the Utility value is received from the multimeter which is placed in PCC. If there is no multimeter in the PCC the value is coming from the protection relay. In the rare case, that neither a multimeter nor a protection device has been installed, the value is coming from the inverters.
  • Production Active Energy value is received from the protection relay.
  • Array Output Energy value is received from the inverters. At the plant level, this parameter corresponds to the sum of the AC output power reported by the inverters.
