PV / Storage PCC Power Quality

Check harmonic voltage, DC injection and flicker at the PV/storage point of common coupling (IEEE 519 / IEC 61000-3-6 / IEC 62109).

Inputs

Inverter rating P kW

PCC short-circuit capacity Sₖ kVA

PCC line voltage V V

Emitted harmonic current I_h A

Rated current Iₙ A

Short-term flicker P_st —

Results

Note — Harmonic voltage at PCC is approximated as I_h·Z_sc. DC injection limit is 0.5 % of rated current; flicker P_st ≤ 1.0. Limits depend on the Isc/I_L ratio and local grid code — verify with the utility and a certified engineer.
