NEN 1010 §712.537.2.2.5
PV DC isolator
DC-scheider (PV-string)
Also known as: dc-separator, pv-switch, dc-scheider, dc-isolator, stringscheider
DC disconnect in each PV string cable directly before the inverter, allowing the array to be de-energized for maintenance without interrupting high voltage at the module box. Mandatory per NEN 1010 §712, suitable for DC operating voltage (Voc × 1.15) and with polarity-correct connection sequence.
Common mistake
Een AC-scheider als DC-scheider gebruiken — AC-scheiders kunnen DC-bogen niet doven en branden in.
