Quick Installation Guide

1. Safety Instruction

• The contents of this document will be updated irregularly for product version upgrade or other reasons. Unless otherwise specified, this document only works as a guide. All statements, information, and suggestions in this document do not constitute any guarantee.
• This product can only be installed, commissioned, operated, and maintained by technicians who have carefully read and fully understood the user manual.
• This product must only be connected with PV modules of protection class II (in accordance with IEC 61730, application class A). PV modules with a high capacitance to ground must only be used if their capacity does not exceed 1µF. Do not connect any sources of energy other than PV modules to the product.
• When exposed to sunlight, the PV modules generate dangerous high DC voltage which is present in the DC cable conductors and live components. Touching live DC cable conductors and live components can result in lethal injuries due to electric shock.
• All components must remain within their permitted operating ranges at all times.
• The product complies with Electromagnetic compatibility 2014/30/EU, Low Voltage Directive 2014/35/EU, and Radio Equipment Directive 2014/53/EU.

2. Mounting Environment

• Ensure that the inverter is installed out of the reach of children.
• To ensure best operating status and prolonged service life, the mounting ambient temperature of the inverter should be ≤40°C.
• To avoid direct sunlight, rain, snow, and ponding on the inverter, it is suggested to mount the inverter in places with a top protective roof. Do not completely cover the top of the inverter.
• The mounting condition must be suitable for the weight and size of the inverter. The inverter is suitable to be mounted on a solid wall that is vertical or tilted backwards (Max. 15°). It is not recommended to install the inverter on walls made of plasterboards or similar materials. The inverter may make noise when working.
• To ensure adequate heat dissipation, the clearances between the inverter and other objects are recommended as follows: 300mm above, 500mm below, 300mm to the left, and 500mm to the right.

2. Insert wall plugs into the wall and fix the wall mounting bracket to the wall by screwing three self-tapping screws (M10 screws). [Diagram shows wall plugs being inserted into drilled holes in a wall, followed by a wall mounting bracket being secured with three self-tapping screws.]
3. Hang the inverter to the wall mounting bracket. [Diagram shows the inverter being hung onto the wall mounting bracket.]
4. Secure the inverter to the wall mounting bracket on both sides using M4 screws. Screwdriver type: PH2 screwdriver, torque: 1.6Nm. [Diagram shows the inverter being secured to the wall mounting bracket using M4 screws on both sides.]
5. If required, you can connect a second protective conductor as equipotential bonding.

5. AC Connection

DANGER All electrical installations must be done in accordance with all local and national rules. Make sure that all DC switches and AC circuit breakers have been disconnected before establishing electrical connection. Otherwise, the high voltage within the inverter may lead to electrical shock.

In accordance with safety regulations, the inverter needs to be grounded firmly. When poor ground connection (PE) occurs, the inverter will report a PE grounding error. Please check and ensure that the inverter is grounded firmly or contact AISWEI service.

1. AC cable requirements are as follows. Insert the conductor into a suitable ferrule according to DIN 46228-4 and crimp the contact. [Diagram illustrates AC cable preparation: a cable with conductors (L1, L2, L3, N, PE) is shown. Conductor B (2.5-6mm²) is crimped with a ferrule. Conductor C (stripping length 13mm) and outer sheath D (stripping length 53mm) are indicated. The PE conductor (D-5mm) is shown to be longer than the other conductors.]

The PE conductor must be 5 mm longer than the L and N conductors.

2. Loosen the swivel nut of the AC connector. Insert the crimped conductors into corresponding terminals and tighten screws with the screwdriver. Screwdriver type: PH1 screwdriver, torque: 0.8Nm.

3. Insert the adapter to the socket element, stuff the seal ring into the adapter and tighten the swivel nut.

4. Plug the AC connector into the socket for the AC connection.

5. If required, you can connect a second protective conductor as equipotential bonding.

6. DC Connection

DANGER Make sure PV modules have good insulation against ground. On the coldest day based on statistical records, the Max. open-circuit voltage of the PV modules must not exceed the Max. input voltage of the inverter. Check the polarity of DC cables. Ensure that the DC switch has been disconnected. Do not disconnect DC connectors under load.

1. Please refer to the "DC Connector Installation Guide".

2. Before DC connection, insert the DC plug connectors with sealing plugs into the inverter's DC input connectors to ensure protection degree. [Diagram shows DC connectors with sealing plugs inserted into inverter DC input connectors.]

7. Communication Setup

DANGER Separate communication cables from power cables and serious interference sources.

• The communication cables must be CAT-5E or higher-level shield cables. Pin assignment complies with EIA/TIA 568B standard. For outdoor use, the communication cables must be UV-resistant. The total length of the communication cable cannot exceed 1000m.
• If only one communication cable is connected, insert a sealing plug into the unused hole of the sealing ring of the cable gland.
• Before connecting communication cables, ensure the protective film or communication plate attached to the communication opening on the inverter is sealed tightly.

8. COM1: RS485 (optional)

1) RS485 cable pin assignment as below: [Diagram shows the pin assignment for an RS485 cable: Pin 1 (TX_RS485A), Pin 2 (TX_RS485B), Pin 3 (NC), Pin 4 (GND), Pin 5 (GND), Pin 6 (NC), Pin 7 (+7V), Pin 8 (+7V).]

2) Loosen the swivel nut of the cable gland on the communication cover, remove sealing plugs and lead the cable through the swivel nut, sealing ring, communication cover, and magnetic ring. [Diagram shows the components of a communication cable gland: cable, swivel nut, sealing ring, communication cover, and magnetic ring.]

3) Insert the cable into the socket, attach the communication cover to the inverter with M4 screws, and tighten the swivel nut. Screwdriver type: PH2 screwdriver, torque: 1.6Nm. [Diagram shows a connected cable inserted into a socket and secured with a swivel nut.]

9. COM2: GPRS/WiFi

PIN Assignment: PIN1: VCC, PIN2: GND, PIN3: RS485A, PIN4: RS485B.

Note: The connection refers to the "GPRS/WiFi-stick User Manual".

10. Smart meter

1. Remove the communication plate from the inverter. [Diagram shows the communication plate being removed from the inverter.]
2. Loosen the swivel nut of the cable gland on the communication plate, remove the sealing plug and lead the stripped cable through the cable gland and communication plate. Press the latch of the smart meter terminal and insert the stripped cable accordingly. Make sure the cable is connected firmly. [Diagram shows a cable gland with a sealing plug removed, a stripped cable threaded through, and a smart meter terminal being pressed and inserted into a socket.]
3. Insert the smart meter terminal to the socket, attach the communication plate to the inverter with M4 screws, and tighten the swivel nut. Screwdriver type: PH2 screwdriver, torque: 1.6Nm. [Diagram shows the smart meter terminal inserted into the socket and the communication plate attached to the inverter, secured with M4 screws and a tightened swivel nut.]
4. If a communication cover is used, remove only one sealing plug of the cable gland to thread the cable. Detailed installation process follows the above steps. [Diagram shows a communication cover with one sealing plug removed from the cable gland to allow a cable to pass through.]

11. Commissioning

Notice

• Check that the inverter is grounded reliably.
• Check that the ventilation condition surrounding the inverter is good.
• Check that the grid voltage at the point of connection of the inverter is within the permitted range.
• Check that the sealing plugs in DC connectors and the communication cable gland are sealed tightly.
• Check that grid connection regulations and other parameter settings meet safety requirements.

1. Switch on the AC circuit breaker between the inverter and the grid.
2. Switch on the DC switch.
3. When there is sufficient DC power applied and the grid conditions are met, the inverter will start to operate automatically.
