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 direct strike or damage from the impact of the surge.

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. Avoiding the creation of 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 across their terminals is typically less than 30 volts.

CAUTION !

For X1-2.5-S-N(L), X1-3.0-S-N(L), X1-3.3-S-N(L), external DC breaker must be connected on the PV side.

2.3 PE Connection and Leakage Current

• The inverter incorporates a certified internal Residual Current Device (RCD) in order to protect against possible electrocution and fire hazard in case of a malfunction in the cables or inverter. There are two trip thresholds for the RCD as required for certification (IEC 62109-2:2011). The default value for eletrocution protection is 30mA, and for slow rising current is 300mA.

• If an external RCD is required by local regulations, check which type of RCD is required for relevant eletric code. It recommends using a type-A RCD. The recommended RCD values is 100mA or 300mA unless a lower value is required by the specific local electric codes. When required by local regulations, the use of an RCD type B is permitted.

WARNING !

High leakage current! Earth connection essential before connecting supply.

• Incorrect grounding can cause physical injury, death or equipment malfunction and increase electromagnetic.

• Make sure that grounding conductor is adequately sized as required by safety regulations.

• Do not connect the ground terminals of the unit in series in case of a multiple installation. This product can cause current with a d.c component, Where a residual current operated protective (RCD) or monitoring (RCM) device is used for protection in case of direct or indirect contact, only an RCD or RCM of type B is allowed on the supply side of this product.

a) Check that device is xed well on the wa ll. b) Make sure all the DC breakers and AC breakers are disconnected. c) AC cable is connected to grid correctly. d) All PV panels are connected to inverter correctly, DC connectors which are not used should be sealed by cover.

5.6.2 Start inverter

a) Turn on switches of DC and AC side. b) Inverter will start up automatically when PV panels generate enough energy. c) Check the status of LED indication and LCD screen, the LED indication should be blue and the LCD screen should display the main interface. If the LED indication is not blue, please check the below:

- All the connections are right.

- All the external disconnect switches are closed.

- The DC switch of the inverter is in the “ON” position.

*The three diﬀerent states of the inverter can refer to the following:

- Waiting: Inverter is waiting to checking when output DC voltage from PV

panels is greater than 65V (lowest start-up voltage) but less than 80V (lowest operating voltage). Under this mode, the blue light “ ” is ickering.

- Checking: Inverter will check output environment automatically when DC output voltage of PV panels. Under this mode, the blue light is flickering.

- Normal: Inverter begins to operate normally with blue light 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 is always on.

WARNING!

Power to the unit must be turned on only after installation work has been completed. All electrical connections must be carried out by qualied personnel in accordance with legislation in force in the country concerned.

NOTE!
