SafetySafety

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 both PV input side and 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 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 3 required for surge protection for electrical devices.

To protect the AC system, surge suppression devices (SPD type2) 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.

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 forshort 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 the voltage loss is happened in the power system. It is dangerous for maintenance personnel and the public. X1 series provide Active Frequency Drift(AFD) to prevent islanding eﬀect.

PV modules shall have an IEC 61730 class A rating. Never touch either the positive or negative pole of PV connecting device. Strictly prohibit touching both of them at the same time. The unit contains capacitors that remain charged to a potentially lethal voltage after the MAINS and PV supply has been disconnected. Hazardous voltage will present for up to 5 minutes after disconnection from power supply. CAUTION-RISK of electric shock from energy stored in capacitor. Never operate on the solar inverter couplers, the MAINS cables, PV cables or the PV generator when power is applied. After switching off the PV and Mains, always wait for 5 minutes to let the intermediate circuit capacitors discharge before you unplug DC and MAINS couplers. When accessing the internal circuit of solar inverter, it is very important to wait 5 minutes before operating the power circuit or demounting the electrolyte capacitors inside the device. Do not open the device before hand since the capacitors time to sufficiently discharge! require Measure the voltage between terminals UDC+ and UDC- with a multi-meter (impedance at least 1Mohm) to ensure that the device is discharged before beginning work (35VDC) inside the device.

*The inverter with LCD can refer to the following:

Waiting: Inverter is waiting to checking when DC input voltage from panels is greater than 60V (lowest start-up voltage) but less than 70V (lowest operating voltage).

Checking: Inverter will check DC input environment automatically when DC input voltage from the PV panels exceeds 70V and PV panels have enough energy to start inverter.

Normal: Inverter begins to operate normally with blue light on. Meanwhile feedback energy to grid, LCD displays present output power.

**Below is three different states of the inverter without LCD when operating, which means inverter starting up successfully.

Waiting: Inverter is waiting to checking when output DC voltage from PV panels is greater than 60V (lowest start-up voltage) but less than 70V (lowest operating voltage). Under this mode, the blue light “a” is flickering, shown as figure (A).

Checking: Inverter will check output environment automatically when DC output voltage of PV panels. Under this mode, the blue light “a” is flickering, shown as figure (A).

Normal: Inverter begins to operate normally with blue light “a” on. Inverter will work in MPPT mode when PV voltage is in the MPPT voltage range, inverter will stop feedback to grid when PV power is not enough. Under this mode, the blue light “a” is always on, light ”1,2,3,4” represent the output power. As shown in figure (B), the output power is 0%~25%".
