Installation of surge protection at the ac-ouput of solar inverters
It is compulsory to install SPD (surge protection devices) at the ac output of a single phase and three-phase solar inverters. The surge protection module will protect the inverter from high voltages that might be detrimental for the MOSFET and IGBT (internal semiconductors). We recommend the following devices with din-rail mounting.
- Single-phase 220-240VAC off-grid/hybrid system
The Citel or Gave Electro will stop any harmful voltages over 270AC. You can find this equipment online
- Three-phase 380/415VAC system
The 3 phase Type 2 surge protector is available from our online shop, please visiti the following link
