PACKAGE LIST

Please check to make sure the packing and all components are not missing or damaged. Please contact your dealer directly for supports if there is any damage or missing components.

A visual diagram shows all the included components.

MOUNTING

Follow these steps for mounting the inverter:

1. Step 1: Prepare the mounting location. Dimensions for placement are approximately 219mm and 264mm.
2. Step 2: Securely mount the inverter to the wall.
3. Step 3: The inverter is now mounted.

Diagrams illustrate the mounting process.

PV CONNECTION

Instructions for connecting the Photovoltaic (PV) array:

1. Step 1: Prepare the PV cable. Suggested cross-section is 4mm². Strip approximately 12-15mm of insulation from the cable end.
2. Step 2: Crimp the positive and negative MC4 connector contacts onto the stripped cable ends using a dedicated PV connector crimping tool. Ensure a secure crimp; a "click" sound indicates correct assembly.
3. Step 3: Connect the crimped PV connectors to the corresponding DC input terminals on the inverter.

Warning: The DC side carries high voltage. Ensure compliance with electric safety standards during connection. Incorrect polarity can damage the inverter.

BATTERY CONNECTION

Instructions for connecting the battery system:

1. Step 1: Prepare the battery cable. Suggested cross-section is 8-10 AWG. Strip approximately 19±1mm of insulation.
2. Step 2: Pass the crimped battery harness through the waterproof connector and its cover.
3. Step 3: Insert the wires into the terminals according to the correct polarity (+ and -). Ensure the insulated terminals are parallel with the terminals. Tighten the crimping screw to 2.0±0.1N.m. A "click" sound will be heard when the connector assembly is correct.
4. Step 5: Use an open-end wrench to tighten the waterproof lock.
5. Step 6: Insert the battery connector into the inverter. A "click" sound confirms the connection is complete.

Diagrams show the battery connection process.

GRID AND EPS CONNECTION

Instructions for connecting to the grid and the Emergency Power Supply (EPS):

1. Step 1: Prepare the grid/EPS cable. Suggested cross-section is 8-10AWG. Strip approximately 10±0.5mm of insulation.
2. Step 2: Connect the GRID and EPS Load cables to the respective terminals on the inverter.

Notes:

• The maximum power load connected to the EPS port must not exceed the inverter's specified EPS Max. output power range.
• Ensure all wiring terminals are wrapped with insulation tape to prevent short circuits, which could damage the inverter.

Diagrams illustrate the grid and EPS connections.

COMMUNICATION AND WIRING CONFIGURATION

RJ45 CABLE PINOUT

The RJ45 connector pin assignments are as follows:

• 1: White-Orange
• 2: Orange
• 3: White-Green
• 4: Blue
• 5: White-Blue
• 6: Green
• 7: White-Brown
• 8: Brown

For CT, Battery, and Meter connections:

• CT: CT-U, CT-N
• BAT: BAT 485A, BAT 485B
• METER: Meter 485A, Meter 485B

Communication signals include 485A/B, CTU/CTN, CANH/CANL.

The mapping for specific devices is:

• 1 = METER
• 2 = BATTERY
• 3 = CT

Diagrams show the connections for CT, Meter, and Battery, along with the RJ45 pinout and communication signal labels.

WIFI CONNECTION

To configure the WiFi connection, set up the Monitor Module, router, and account registration. Refer to the dedicated WiFi connection manual for detailed instructions.

GROUND CONNECTION

Proper grounding is essential for safety:

1. Step 1: Prepare the earth cable. Suggested cross-section for copper is 4-6mm² / 10AWG. Strip approximately 10 ±0.5mm of insulation.
2. Step 2: Securely fix the grounding screw to the grounding connection point on the machine housing.

Note: Ensure that the earth cables for the inverter and the solar panel frame are connected separately.

Diagrams illustrate the grounding connection process.

BATTERY COMMISSIONING

The battery commissioning process involves setting operating parameters and selecting the battery type. The process is outlined in a flowchart:

• Start with "Run Param" to access "Operating parameters setting".
• Proceed to "Bat Param".
• Select battery type: "Lithium" or "LeadAcid".
• Follow the configuration path: "Auto Match" can lead to "Sel Lith Brand" or "Matching Afore". "Sel Lith Brand" further branches to "Lithium Pylon Pytes" or "Lithium Pylon". "Matching Afore" leads to "match OK Pylon".

A flowchart diagram visually represents these steps.
