Wi-Fi and solar monitoring help
Use this guide if your inverter’s monitoring app shows offline after an internet, router or password change. The correct reconnection method depends on your inverter, communication device and app version. Keep the existing equipment details handy and use the matching manufacturer’s guide below.
Wi-Fi is a third-party service
Your home or business Wi-Fi and internet connection are separate from the solar electrical installation. Routers, modems, internet subscriptions, signal coverage, network passwords and ongoing IT support are managed by you or your internet/IT provider unless separately agreed. Initial monitoring setup is included only where your quote specifies it, and needs a suitable working connection.
A communications device supplied with the solar system is different from the customer network. A defective supplied device can be assessed as a product issue. Read Warranty Q and A for the distinction between installation scope, external services and warranty support.
Offline monitoring does not always mean failed solar
A lost internet connection can stop data reaching the cloud app while the inverter continues operating. However, an app message alone cannot confirm that the system is healthy. Check the equipment display and status from a safe position, following the model’s instructions. Record any fault code. Status light colours differ between models; do not assume that one colour proves normal operation.
Start with these checks
- Check your internet: can a phone or computer use the internet through the same router? Ask your provider about outages if it cannot.
- Check what changed: a replacement router, new network name or changed password usually requires reconnection of the solar communications device.
- Check coverage: a strong signal beside the router does not guarantee coverage at the inverter. Ask your IT provider about suitable network coverage or a compatible wired option.
- Check the device requirements: many solar communication devices need 2.4 GHz Wi-Fi. Confirm the exact model and security requirements. A dual-band router may work without splitting all its bands; follow the device and router instructions.
- Use the correct app and guide: select your brand below. Use authorised owner access. If a step requires installer access or settings you do not understand, contact support.
- Confirm fresh data: reconnect your phone to its usual internet connection and check the app’s most recent data time. Allow the model’s stated reporting interval.
Before changing settings
Do not open electrical covers, change grid profiles, export limits, protection settings, battery configuration or factory-reset the system just to restore Wi-Fi. Follow only the communications procedure for your model. Device passwords may have been changed at installation; do not rely on a generic default password.
Keep Wi-Fi and account passwords private. If an authorised app temporarily connects your phone to the inverter’s local hotspot, that hotspot may show no internet access. Follow the manufacturer prompts and reconnect to your normal network afterwards. Do not weaken your router’s security to make a device connect.
Manufacturer connection guides
GoodWe uses different communications hardware and apps across its range. SEMS Portal monitoring and SolarGo configuration instructions must match the installed device. Newer kits may support Bluetooth-assisted setup and optional LAN connections.
Use the official GoodWe Wi-Fi configuration instructions, then confirm the device is reporting in your monitoring account. Refer to the GoodWe support FAQ for model-specific troubleshooting.
Identify the inverter and communication device first. Older iStore installations may use HiSolar; follow the app and instructions supplied for your model rather than applying Huawei steps to every iStore product.
Use the official iStore manuals and setup resources. If the correct network settings cannot be accessed with your authorised account, contact support for the appropriate next step.
Huawei’s current owner guidance includes WLAN Configuration under the Services tab to reconfigure router connection parameters. The available path depends on equipment and app version.
Follow Huawei’s official Router Connection guide. Use only the network settings applicable to your installation and confirm new data in FusionSolar.
Solis logger generations have different setup methods. Identify the logger model and use the matching SolisCloud instructions.
See the Solis Wi-Fi configuration guide and network troubleshooting guide. Check SolisCloud’s last reporting time after setup.
SnapINverter/Datamanager and GEN24 installations use different procedures. Choose the guide that matches the inverter before changing network settings.
Use GEN24 support, SnapINverter support or Solar.web support. Do not remove covers to access a reset control.
Check the Pocket communication device and SolaXCloud app version. The current app guide includes Network Configuration, but the correct method depends on the device.
Follow the official SolaXCloud configuration guide or the matching resources on the Pocket WiFi support page.
SMA equipment and portal generations differ. Use the manual for the exact inverter and communications product and the owner account supplied at handover. Do not run an installation assistant or change country/grid settings to reconnect Wi-Fi.
Use SMA’s official website to select your product documentation and service support. Contact us if your model or authorised access is unclear.
Identify whether you have a ShineWiFi, ShineWLAN or another logger before following a setup procedure. Different generations use different connection methods.
Use the matching guide from Growatt Australia’s manuals and quick guides or the ShineWiFi/ShineWLAN product resources, then confirm recent data in your monitoring app.
When to contact Greenbank Solar
Contact us if there is an equipment fault code, suspected failed communications hardware, an unresolved connection issue or uncertainty about the correct procedure. Provide the inverter and logger model, app name, last successful reporting date, screenshots and details of recent network changes. Do not include passwords.
Separately agreed network troubleshooting or a service visit may be chargeable where the cause is outside installation, product warranty and consumer guarantee obligations. We explain the proposed scope before proceeding. An offline app alone does not establish whether the issue is covered.
