Troubleshooting Power line noise
Power line noise is electrical interference caused by other
devices sharing the same electrical wiring at the same site. This interference
inhibits IQ Gateway communication with the microinverters, resulting in
inconsistent production reporting in the Enphase Installer Portal.
Common causes of power line noise
• Power strips
• GFI outlets
• Dimmer switches
• Appliances with heavy motors (refrigerators, washing machines)
• Security systems
• Bad circuit breakers
In addition to relocating the device, Enphase also
recommends trying to isolate the source of the power line noise by installing
ferrite toroid rings on the suspected circuit.
If the system is still impacted by power line noise even
after relocating the device and installing ferrite rings, the best practice is
to install a dedicated circuit off the main service panel to isolate the
system’s power. Please contact an electrician to do so. After installing a
dedicated circuit, the installer can install ferrite toroid rings at the new
location for extra precaution.
