Step 1Quick Installation Instructions
Installation Space
Ensure adequate clearance around the inverter for proper ventilation and maintenance:
- Above: 300mm
- Below: 500mm
- Front: 300mm
- Left & Right: 200mm
Drilling Dimensions
Prepare the wall for mounting using the following dimensions for drilling holes:
- Horizontal spacing: 228.5mm (center to center)
- Vertical spacing: 117.5mm (top to bottom)
- Bracket height: 104.5mm
- Total width for bracket: 400mm
Attaching the Wall Bracket
Secure the wall bracket using expansion tubes and self-tapping screws.
Inverter Installation
The inverter can be locked for anti-theft protection. A grounding cable must be connected to the grounding plate on the grid side.
Battery Wiring Assembly and Connections
Connect the battery cables to the inverter terminals. Ensure proper polarity.
| Grade | Description | Value |
|---|---|---|
| A | Outer Diameter Insulation | 10-14 mm |
| B | Insulation Section | NA |
| C | Conductor Core Section | 20-35 mm² |
DC Cable Assembly and Connection
Use a dedicated PV DC cable (e.g., PV1-F 4 mm²). Connect positive (+) and negative (-) connectors. Special crimping tools are required. The limit clip must not be crimped.
Warning: Reversed polarity will damage the inverter!
It is normal for an electric arc to occur when connecting the battery to the inverter without a DC breaker. Tighten pan head screws to 6-8 Nm.
AC Cable Assembly and Connections
Verify that L, N, and PE cables are connected to the correct locations.
| Grade | Description | Value |
|---|---|---|
| A | Outer Diameter | 13-18 mm |
| B | Separated Wire Length | 20-25 mm |
| C | Conductor Wire Length | 7-9 mm |
| D | Conductor Core Section | 4-6 mm² |
DRED Cable Assembly
This connection is available only for Australia and New Zealand. Remove the 6-pin terminal and resistor, keeping the terminal for subsequent steps. The 6-pin terminal on the inverter has the same function as an external DRED device; leave it if no external device is connected.
Remote Shutdown Cable Assembly
This connection is available only in Europe.
Wiring System for ES Line Hybrid Inverter
This diagram illustrates the standard electrical wiring structure for the ES line hybrid inverter. Select circuit breakers according to the specifications below:
| No. | Inverter Model | DC Breaker | AC Breaker (Grid) | AC Breaker (Backup) |
|---|---|---|---|---|
| 1 | GW3648D-ES | 125 A / 60 V | 25 A / 400 V | 16 A / 230 V |
| 2 | GW5048D-ES | 125 A / 60 V | 32 A / 400 V | 20 A / 230 V |
- For batteries with an integrated breaker, the external DC breaker can be omitted.
- This applies only to Lithium batteries with BMS communication.
- Use Current Transformers (CT) A for L1, B for L2, and C for L3. Connect in the direction "House (K) → Grid (L)". Otherwise, an error reminder will appear in the PV Master App.
Step 2POP for Battery Connection
Note: This manual covers only battery-inverter connection methods for GoodWe inverters. For other battery operations, consult the battery user manual. This manual covers only some battery models, which are subject to change without prior notice.
1. BYD B-BOX (Hybrid Inverter)
Before connecting, ensure both the inverter and battery bank are OFF. If multiple battery banks are connected, battery address definition is required (refer to battery manual).
Connect the inverter cables to the BYD battery terminals: negative to "P-" and positive to "P+". Prepare the cable by cutting the plastic cover, passing it through the terminal cover, crimping the metal part to the battery's R-type terminal (25-8), connecting to the hybrid inverter terminals, and replacing the cover.
The battery communication cable connects to the BYD battery's CAN port. In PV Master, select the correct battery model. After all connections and settings are complete, verify that the battery communication status in PV Master (Param → BMS Status) is "Normal".
2. GCL E-KwBe (Hybrid Inverter)
Before connecting, ensure both the inverter and battery bank are OFF. For multiple batteries (max 4), refer to the battery user manual for configuration.
Connect the inverter cables to the GCL battery terminals: negative to "-" and positive to "+". Prepare the cable similarly to BYD. The battery communication cable connects to the GCL battery's CAN port. In PV Master, select the correct battery model. After all connections and settings are complete, verify that the battery communication status in PV Master (Param → BMS Status) is "Normal".
3. LG RESU (Hybrid Inverter)
Before connecting, ensure both the inverter and battery bank are OFF. Remove the LG battery's top cover. Connect energy cables to terminals via the insulating ring. Prepare the cable similarly to previous steps. The battery communication cable connects to the LG battery's CAN port.
Set the DIP switches and rotary switches on the battery as detailed in the battery manual. (Note: RESU6.4EX models do not have DIP switches). In PV Master, select the correct battery model. After all connections and settings are complete, verify that the battery communication status in PV Master (Param → BMS Status) is "Normal".
4. Pylon (US2000 and US3000 Hybrid Inverters)
Before connecting, ensure both the inverter and battery bank are OFF. Connect the inverter cables to the Pylon battery terminals: negative to the black terminal and positive to the orange terminal. Prepare the cable similarly to previous steps. The battery communication cable connects to the Pylon battery's CAN port. In PV Master, select the correct battery model. After all connections and settings are complete, verify that the battery communication status in PV Master (Param → BMS Status) is "Normal".
5. Dyness (B4850 Hybrid Inverter)
Before connecting, ensure both the inverter and battery bank are OFF. If multiple battery banks are connected, battery address definition is required (refer to battery manual).
Connect the inverter cables to the Dyness battery terminals: negative to the black terminal and positive to the red terminal. Prepare the cable similarly to previous steps. The battery communication cable connects to the Dyness battery's CAN port. In PV Master, select the correct battery model. After all connections and settings are complete, verify that the battery communication status in PV Master (Param → BMS Status) is "Normal".
6. Alpha (Smile5-Bat Hybrid Inverter)
Before connecting, ensure both the inverter and battery bank are OFF. For multiple batteries (max 40), refer to the battery user manual for configuration. The battery indicator should be off.
Connect the inverter cables to the Alpha SMILE5 battery terminals: negative to the black terminal and positive to the red terminal. Prepare the cable similarly to previous steps. The battery communication cable connects to the Alpha battery's CAN port. In PV Master, select the correct battery model. After all connections and settings are complete, verify that the battery communication status in PV Master (Param → BMS Status) is "Normal".
Step 3Wi-Fi Configuration Instructions
Note: Wi-Fi configuration can also be performed using the PV Master App. For details, download the "PV Master Operation Introduction" from br.goodwe.com.
Preparation
- Turn on the inverter's Wi-Fi module (or the inverter itself).
- Turn on the router.
Connect to "Solar-Wi-Fi"
Access the inverter's Wi-Fi interface via a web browser at 10.10.100.253. Log in using the default username "admin" and password "admin". Click "OK".
Configuration
Click "Start Setup". The Wi-Fi module information is displayed on the left. Select your current wireless network from the list on the right. If the router does not broadcast its SSID, you may need to add the wireless network manually.
Helpful Tip: If the RSSI (Received Signal Strength Indicator) of the selected Wi-Fi network is below 15%, the connection may be unstable. Choose another available network or reduce the distance between the device and the router.
Troubleshooting Connection: A "Cannot join the network" message may be caused by the router not existing, a weak signal, or an incorrect password.
Manual Wi-Fi Network Connection
If your network is not listed, fill in the router's password and click "Next". For manual addition, provide the Network name (SSID), Encryption method, and Encryption algorithm. Ensure all parameters match your router's settings, including case sensitivity for SSID and password.
After saving, click "Complete". The configuration will take effect after a restart. You can log in to the Management page to restart the device.
Important: The "Solar-Wi-Fi" signal will disappear once the inverter connects to a router. To reconnect to "Solar-Wi-Fi", turn off the router or perform a Wi-Fi reload operation via the button on the inverter.
