Photovoltaic systems by segments

The photovoltaic market is categorized by three segments which needs different protection of electric circuits.

• Residential (Rooftop)
• Commercial
• Utility

Photovoltaic: Residential and Commercial

Business led by small to medium-sized companies. Main customers:

•  Installers
• Wholesalers
• Panel builders

Photovoltaic: Utility-scale Systems

Photovoltaic: Central inverter System

Cylindrical Fuse-links (UL Certified)

CH gPV: String inverters

CH gPV: DC Combiner box

NH Fuse-links ( UL Certified )

Photovoltaic: String inverter System

The main purpose of the protection on a.c. side is the protection of cables and installations between PV smart string inverter and the transformer station. Fuse-links have to be designed for uninterruptible operation in case of short-time overloads which could become a consequence of higher temperatures and the peak of power generation.
