Sensors

Our selection includes sensors from leading manufacturers such as Enphase, SolarEdge and KOSTAL, specialized in precise monitoring and secure system control. This product family stands out for its high measurement accuracy, robust design and easy integration into energy management systems. Typical applications are private rooftop systems, commercial roofs and commercial storage systems with monitoring and feed-in control.

Functions and Benefits of PV Sensors

Sensors capture current, irradiance and temperature and provide the basic data for yield analysis, fault detection and performance optimization. They increase operational reliability through early fault detection, enable precise load and feed-in control, and support grid compliance. Both small residential systems and large commercial projects benefit from improved efficiency and documented system performance.

Technical Features and Operating Principles

This product group is based on current transformers (CT/Hall), irradiance and temperature sensors. Key features include galvanic isolation, measurement accuracy (classified error limits), IP protection classes for outdoor installation, and durable materials. Data is fed into energy management systems via standardized interfaces (Modbus, RS485, proprietary buses), enabling control algorithms and storage strategies to operate efficiently. Robustness and calibratability ensure long-term reliability.
