Part 2: Standard Operating Procedure (SOP) for Battery Connection

This section details connecting compatible batteries to the EH inverter.

Note: If your inverter is battery-ready, obtain an activation code and activate the battery function in PV MASTER before connecting the battery. This guide only covers connection methods. Refer to the battery's user manual for other operations.

1. BYD B-BOX Connection

For BYD Battery-Box H 6.4/7.7/9.0/10.2 with the inverter.

1. Power Off: Ensure the inverter and batteries are powered off before connecting.
2. Connect Power Cables: Connect the power cables to the BYD Battery Management Unit (BMU) terminals: positive cable to 'P+' and negative cable to 'P-'.
3. Connect to Inverter: Connect the other end of the power cable to the hybrid inverter's terminals.
4. Connect Communication Cable: Connect the battery communication cable to the inverter.
5. Connect to BMU: Connect the other end of the 'To Battery' cable to the CAN port of the BYD BMU box. Detach the blue-white and blue conductors from the cable; connect the blue-white conductor to the second terminal and the blue conductor to the third terminal.
6. Connect BMS Cable (if applicable): For battery-ready inverters, purchase an RJ45 cable and connect it to the inverter's BMS port as shown.
7. Select Battery Model: In PV Master, select the correct battery type used in your system under "Select Battery Model".
8. Check Communication: After all connections and settings are complete, check "PV Master > Param.BMS-Status" to ensure communication is OK. The status should display "Communication OK".

2. Pylon Power Cube Connection

For Pylon Power Cube-H1*4/5/5/6/7/8 with the inverter.

Note: The maximum battery charge (SOC) is 90% and cannot be increased to 100%.

1. Power Off: Ensure the inverter and batteries are powered off before connecting.
2. Series Connection (Battery Packs): Connect battery packs in series:
   • Power Cables: Connect 'B+' of the BMU to 'B+' of the first battery pack and 'B-' of the BMU to 'B-' of the last battery pack. Connect 'B+' to 'B-' between adjacent battery packs. The orange end is 'B+', and the black end is 'B-'.
   • Communication Cables: Connect the 'Link Port' of the BMU to 'Link Port0' of the first battery pack. For adjacent battery packs, connect 'Link Port1' sequentially to 'Link Port0' of the next battery pack.

   Note: The ADD selector switch must be set as shown.

3. Connect Inverter Power Cables: Connect the power cables to the Pylon BMU terminal block: positive cable to 'P+' and negative cable to 'P-'.
4. Connect to Inverter: Connect the other end of the power cable to the hybrid inverter's terminals.
5. Connect Battery Communication Cable: Use the BMS cable as the communication cable. Connect the 'To Battery' cable end to the CAN/Link port B of the Pylon BMU box.
6. Power On and Check: Turn on the battery using the switch, then press the red button for 2 seconds. The status light should turn green. Wait about 30 seconds to check if BMS communication is normal and the status light remains green. If the status light turns red, press the red button for 5 seconds. If it turns green again, the battery system is ready.

C. Device Information Screen

This screen displays device information such as Firmware version, MAC address, and current wireless modes.

• Wireless AP Mode: Enable this to create a Wi-Fi hotspot.
• Wireless STA Mode: Disable this when setting up the connection to your home router.
• Router SSID: The name of your home Wi-Fi network.
• Encryption Method/Algorithm: Select the appropriate security settings for your router.
• Router Password: Enter your home Wi-Fi password.

If the router is not listed, proceed to the troubleshooting section.

E. Troubleshooting

Problem 1: WLAN network "Solar-WiFi" not found.

• Steps: Ensure inverter is on, move device closer, restart inverter, perform WLAN restart.

Problem 2: Cannot connect to "Solar-Wi-Fi".

• Steps: Ensure username "admin" and password "admin" are correct, perform WLAN restart, try a different browser, verify the website address spelling.

Problem 4: Router SSID not found.

• Steps: Move router closer or use a repeater, check router's transmission channel (ensure it's not higher than 13).

Problem 5: WLAN network "Solar-WiFi" not found (after initial setup).

• Steps: Restart inverter, reconnect to "Solar-WiFi" and re-login, verify SSID, Security Mode, Encryption Type, and Pass Phrase match router settings. Check router's maximum transmission power and channel. Restart router. Move router closer or use a repeater.

Problem 6: After configuration completion, the WLAN LED blinks four times.

• Steps: Connect to the router and check if www.goodwe-power.com is accessible. Restart router and inverter.
