Troubleshooting

If the module fails to be connected to the iSolarCloud, troubleshoot as follows:

No./ Fault /Corrective Measure

1. WLAN indicator is off
   • Check, through the iSolarCloud App or the built-in Web, if the module is connected to the home router.
2. WLAN indicator blinks fast
   • Check, through the iSolarCloud App, if the module is connected to the home router.
3. WLAN indicator is on for more than 1 min
4. Check and ensure that the home router can access the network normally.
5. Check the whitelist/blacklist settings of the home router. Add the domain name (iot.isolarcloud.com, iot.isolarcloud.com.hk, iot.isolarcloud.eu,auiot.isolarcloud.com) to the whitelist or remove it from the blacklist when necessary.
6. Check the home router settings and ensure that the port 19999 and 16668 are not blocked.
7. If the fault still persists, contact SUNGROW.
