[RE-wrenches] Seeking Advice on LG Solar Panel RMA Process

[Lou Russo]

Aloha All,

Does anyone have experience with the RMA process for LG Solar Panels?

We maintain a 98.58kW system made up of 318 LG310NIC-G4 panels, though we
did not install it. During our annual inspection, we identified two
defective panels on one string. After a quick visual check of the
surrounding section, we found 12 additional panels with similar defects. At
first glance, it appears that water has penetrated the panels. We plan to
conduct a thorough inspection next month and would like to prepare in
advance by understanding what information LG requires and what their RMA
process entails.

While we’ve only installed a handful of LG panels over the years and
haven’t encountered issues before, this is new territory for us.

So far, I’ve reached out to *solar at lgsupport.com* and called *888-865-3026*,
but I haven’t received a response yet. I also came across a 2021 LG RMA
form, which outlines a rather detailed and time-intensive process. It is
comparable to SolarEdge’s optimizer RMA process, requiring multiple photos,
multimeter readings, and IR imaging for each affected panel.

Can anyone confirm if this is still LG’s current process?

For reference, the issue initially presented as a consistent early-morning
ground fault warning at the inverter.

Happy Holidays!
Aloha,
