Q3 PV Technology: Firefighter Switches and AC/DC Connection Technology
Technical fundamentals, operating principles and planning guidance for PV firefighter switches, PV combiner boxes, DC combiners, AC connection boxes and transformer station monitoring.
PV Firefighter Switches and
Generator Disconnection
DC-side PV string shutdown, galvanic isolation and fail-safe operation for integration into fire alarm and emergency shutdown concepts.
DC Connection Technology
for PV Systems
Design of PV combiner boxes, string boxes and DC combiner systems based on PV strings, MPPTs and inverter data, individually equipped.
AC Connection Technology
and Grid Configurations
Design of AC connection boxes based on grid configuration, feed-in point, protection functions and project-specific requirements.
Transformer Station Monitoring
and Grid Monitoring
Measurement, communication and retrofit solutions for transformer stations – enabling central monitoring of grid and system data.
