Surge protection devices (SPDs) for PV installation WARNING! Over-voltage protection with surge arresters should be provided when the PV power system is installed. The grid connected inverter is fitted with SPDs in MAINS side. Induced surges are the more likely cause of lightning damage in the majority of installations, especially in rural areas where electricity is usually provided by long overhead lines. Surges may be induced on both the PV array conductors or the AC cables leading to the building. Specialists in lightning protection should be consulted in the actual application. Using appropriate external lightning protection, the effect of a direct lightning strike into a building can be mitigated in a controlled way, and the lightning current can be discharged into the ground. Installation of SPDs to protect the inverter against mechanical damage and excessive stress includes a surge arrester in the case of a building with external lightning protection system (LPS) when separation distance is kept. To protect the DC system, surge protection device (SPD type 2) should be fitted at the inverter end of the DC cabling and at the array located between the inverter and the PV generator, if the voltage protection level (VP) of the surge arresters is greater than 1100V, an additional SPD type 2 is required for surge protection for electrical devices. To protect the AC system, surge protection devices (SPD type 2) should be fitted at the main incoming point of AC supply (at the consumer's cutout) , located between the inverter and the meter / distribution system; SPD (test impulse D1) for signal line according to EN 61632-1. Spark gap protection devices are not suitable to be used in DC circuits once conducting, they won't stop conducting until the voltage passes through their terminals typically less than 30 volts. 04 Safety Anti-Islanding Effect Islanding effect is a special phenomenon that grid-connected PV system still supplies power to the nearby grid when electrical grid power is no longer present. It is dangerous for maintenance personnel and the public. The inverter provides Active Frequency Drift (AFD) to prevent islanding effect. 2.2 Important Safety Instructions DANGER!
