Float Controller SI
Module protection to prevent the PID effect
PV plants with string inverter or small central inverter can easily be protected by Float Controller SI. This device handles up to 110kWp and is operating only during inverter inactivity.
- Quick regeneration of PID affected modules
- Increasing PV module lifetime in ungrounded systems
- System voltage up to 1000V
- Especially designed for string inverters
- Higher plant efficiency and yield over 20 years
- Float Controller SI Installation
