er until all power supply sources have been switched off for at least 5 minutes.
Keep the distance between the DC+ and DC- conductors as small as possible
Avoid cable loops caused by cables that are too long (coil effect)
Use metal cable ducts where possible
Do not place DC cables from different inverters in the same cable duct or
cable tray
