NEN 1010 §712
PV installation
PV-installatie (zonnepanelen)
Also known as: pv, photovoltaic, zonnepaneel, zonnepanelen, terugvoeding-pv, back-feed-protection
PV system (solar panels). DC string 600–1500 V DC via inverter to AC grid. Requirements: DC-side isolator switch, AC-side Type-2 SPD, Type B RCD for inverters without galvanic isolation, correct PV cable colors (black/red-DC, not blue).
Practical example
PV system (solar panels): A PV system with 20 series panels delivers ~800 V DC open-circuit voltage to the inverter, protected by a DC disconnect and Type-2 SPD.
Common mistake
PV installation (solar panels) Common mistake: Confusing black/red DC PV string conductors with standard blue N — PV string DC cables follow their own color code, not the AC convention.
