Safe grid separation­ for photovoltaic systems

Grid and system protection fulfills a variety of standards for international use
Industry:
Photo­voltaics
Series/Measures
Voltage
Product:
NA003
Data sheet:
Task:
When a photovoltaic system is coupled to the public power grid, the power inverter must be equipped with a grid and system protection device that continually checks the grid quality and immediately decouples the system when a fault is detected. In this way, unintentional isolated operation is prevented, thereby avoiding a dangerous situation for maintenance personnel. Manufacturers of inverters require grid and system protection that fulfills the various standards of different countries with a single unit.
Solution
Grid and system protection from TELE safely separates photovoltaic systems from the grid in the event of a fault. The unit is programmable, making it suitable for all international standards.
Use/value:
- Ready for international use
- Freely programmable
- Flexible universal power supply
- Random thresholds and switching times for non-adjustable power generation possible
- Functional safety and detection of islanded operation
- Sealed and password protected
