(Volt/VAR, Volt/Watt, Frequency-Watt) Kora supports SunSpec-compliant DER behavior to meet modern grid interconnection requirements and utility rules.
• Volt/VAR – Reactive power support based on voltage
• Volt/Watt – Active power curtailment at high voltage
• Frequency-Watt – Active power response to frequency deviations
These functions align with IEEE 1547 and Rule 21 requirements.
• Grid profiles are selected during commissioning
• Control curves are applied automatically based on region and utility
• Field modification of utility-mandated curves is restricted
• Verify correct utility and region selection
• Confirm active DER modes via commissioning tools
• Document applied profiles for AHJ and utility records
