Scenario 3: FusionSolar App Cannot Access the Internet
- Access Device commissioning.Figure 6-6 Device commissioning (before login)
If FusionSolar app can access the network, you can access Device commissioning after login to FusionSolar app.
- Connect to the inverter WLAN. Log in as installer, and perform Quick settings.
- When the inverter is directly connected to the mobile phone using the built-in antenna, the distance between the inverter and mobile phone must be less than 5 m without obstructions in between to ensure the communication quality between the FusionSolar app and inverter. The distance is for reference only and may vary depending on mobile phones and whether there are obstructions between the inverter and the mobile phone.
- When connecting the SUN2000L to the FusionSolar app over a router, ensure that the mobile phone and inverter are in the WiFi coverage of the router and the SUN2000L is connected to the router.
- The router supports WiFi (IEEE 802.11 b/g/n, 2.4 GHz) and the WiFi signal reaches the inverter.
- The WPA, WPA2, or WPA/WPA2 encryption mode is recommended for routers. Enterprise-level encryption is not supported (for example, public hotspots requiring authentication such as airport WiFi). WEP and WPA TKIP are not recommended because these two encryption modes have serious security defects. If the inverter cannot be connected using WEP, log in to the router and change the encryption mode to WPA2 or WPA/WPA2.
Figure 6-7 Quick settings- The initial password for connecting the inverter WLAN is Changeme.
- The initial password of the installer is 00000a.
- Use the initial password upon first power-on and change it immediately after login. To ensure account security, change the password periodically and keep the new password in mind. Not changing the initial password may cause password disclosure. A password left unchanged for a long period of time may be stolen or cracked. If a password is lost, devices cannot be accessed. In these cases, the user is liable for any loss caused to the PV plant.
- To set more parameters, tap Parameter configuration.
- (Optional) When multiple inverters are connected to a third-party data collector, set RS485 parameters.Figure 6-8 RS485 Settings
The RS485 addresses of different inverters must be different.
