Integrating with SunSpec DER Models

(Volt/VAR, Volt/Watt, Frequency-Watt) Kora supports SunSpec-compliant DER behavior to meet modern grid interconnection requirements and utility rules.

Supported Functions

• 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.

Configuration Principles

• Grid profiles are selected during commissioning

• Control curves are applied automatically based on region and utility

• Field modification of utility-mandated curves is restricted

Installer Responsibilities

• Verify correct utility and region selection

• Confirm active DER modes via commissioning tools

• Document applied profiles for AHJ and utility records
