Elektrische aansluiting SMA Solar Technology AG
28 SB12-17-IA-nl-52 Installatiehandleiding
5.4 Aansluiting van de PV-generator (DC)
5.4.1 Voorwaarden voor de DC-aansluiting
Eisen aan de PV-modules van de aangesloten strings:
identiek type
identiek aantal
identieke positie
identieke hellingshoek
De aansluitkabels van de PV-modules moeten eveneens van connectors zijn voorzien. De voor
de DC-aansluiting benodigde DC-connectors worden meegeleverd.
De volgende grenswaarden aan de DC-ingang van de omvormer mogen niet worden
overschreden:
Gebruik van verlooppluggen
Verlooppluggen (Y-pluggen) mogen in de directe nabijheid van de omvormer niet
zichtbaar of vrij toegankelijk zijn.
DC-stroomkring mag niet via verlooppluggen onderbroken worden.
Neem de werkwijze voor de vrijschakeling van de omvormer in acht zoals in
hoofdstuk 7.2”Omvormer openen” (Pagina44) beschreven.
Omvormer Maximale ingangsspanning Maximale ingangsstroom
SB 1200 400 V (DC) 12,6 A (DC)
SB 1700 400 V (DC) 12,6 A (DC)
GEVAAR!
Levensgevaar door elektrische schok of vuur!
De maximale ingangsstroom per string is door de gebruikte connectors beperkt. Bij een
overbelasting van de connectors kan dit tot een vlamboog leiden en bestaat er
brandgevaar.
U dient er op te letten dat de ingangsstroom per string niet hoger is dan de maximale
doorgangsstroom van de gebruikte connectors.
