At opretholde en høj isolationsmodstand i et solcelleanlæg er afgørende for driftssikkerhed, personsikkerhed og effektiv energiudnyttelse. For at et solcelleanlæg skal yde optimalt – både inden for bæredygtig energi og økonomi – er korrekt installation og kontinuerlig isolationsovervågning en nødvendighed. Dette gælder især store solcelleparker, hvor mange moduler tilsluttes i parallel, og hvor fejlfinding kan være krævende.
Lavt isolationsniveau – udfordring og løsning
Solcellesystemer (PV-anlæg) består af et stort antal moduler, der er elektrisk forbundet i serie og i parallel. Men isolationsmodstanden er koblet i parallel til jord, hvilket kan reducere anlæggets samlede isolationsniveau væsentligt. Ifølge IEC 61215 skal et enkelt PV-modul have en minimums isolationsværdi på mindst 40 MΩ·m². I store solcelleparker på flere megawatt kan denne værdi dog falde til blot få kΩ på grund af det høje antal PV-moduler.
En pålidelig isolationsovervågning er derfor essentiel for at opdage fejl tidligt og minimere sikkerhedsrisici. ISOMETER® isoPV-serien fra Bender muliggør præcise og kontinuerlige målinger af isolationsniveauet for at overvåge anlæggets tilstand døgnet rundt. Vores teknologi garanterer maksimal sikkerhed og tilgængelighed – et afgørende konkurrenceparameter for sikker og effektiv drift af store PV-systemer.
Sådan påvirker antallet af solcellemoduler isolation
Modulstørrelse og ydelse
Ét PV-modul (1×2 m = 2 m²) har typisk et nominelt output på 400 W.
