Safety

2.1 Appropriate Usage
The X1 Series are PV inverters which can convert the DC current of the PV generator into AC current and feed it into the public grid.

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 tted with SPDs in MAINS side.

Lightning will cause a damage either from a direct strike or from surges due to a nearby strike.
Induced surges are the most likely cause of lightning damage in majority or installations, especially in rural areas where electricity is usually provided by long overhead lines. Surge may be included on both the PV array conduction and the AC cables leading to the building.
Specialists in lightning protection should be consulted during the end use 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 include a surge arrester in case of a building with external lightning protection system (LPS) when separation distance is kept.
To protect the DC system, surge suppression device (SPD type2) should be tted 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 3 required for surge protection for electrical devices.
To protect the AC system, surge suppression devices (SPD type2) should be tted 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.
All DC cables should be installed to provide as short a run as possible, and positive and negative cables of the string or main DC supply should be bundled together. Avoid creating loops in the system. This requirement for short runs and bundling includes any associated earth bundling conductors.
Spark gap 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.
Anti-Islanding Effect
Islanding effect is a special phenomenon that grid-connected PV system still supply power to the nearby grid when electrical grid power is no longer present. It is dangerous for maintenance personnel and the public.
X1 series provide Active Frequency Drift(AFD) to prevent islanding effect.

2.2 Important Safety Instructions
