6.0 Troubleshooting
Problem: IP address shows “192.168.131.228”
If the above IP address shows on the MagWeb’s LCD, the MagWeb
GT did not successfully obtain a DHCP IP address from the router.
Solution: Check network connectivity to the router or other DHCP
server. Typically, the MagWeb GT is not communicating with the
router. You may need to contact the Internet provider, or refer to
your router’s documentation for troubleshooting assistance.
Problem: A “–W” shows on the MagWeb GT LCD display
If the MagWeb’s LCD display shows “–W”, the MagWeb is either not
communicating with the microinverters or the Internet.
Solution: Reboot the MagWeb by unplugging the power cord for
at least seven (7) seconds, and then plugging it back in. If the LCD
display still indicates “–W”, check the communication between the
microinverters and the MagWeb GT, or check your router.
Problem: A“!” following the Reporting Inverters number
If the reporting inverters number is followed by an “!”, then the
number of reporting inverters does not match the number of
MicroGT 500 inverter IDs that have been programmed into the
MagWeb GT. This may indicate the MagWeb GT is having diffi culty
communicating over the power line*. It could also be caused by
low sunlight, resulting in PV module voltage that is too low for the
microinverter to power up.
Solution: Plug the MagWeb GT into a different dedicated electrical
socket. Keep it away from your router.
* Noise in the Wiring System
If there are loose wires in outlets or there are too many other
appliances plugged in near the MagWeb GT, then a signifi cant
amount of “line noise” can build up. This is a phenomenon similar
to static on a television screen, or background buzz on an AM radio
station. Faulty electrical connections may be able to operate without
actually shorting, but still be loose enough that the connection is
creating noise in the line. This is common in older house wiring
which may have a loose ground wire in one of the outlets, which can
result in some level of noise.
Also, newer power systems that are designed with surge protection
devices may have a dampening effect on communication through
home wiring.
