You are talking about the LG RESU10 H right?

Hi my fellow wrenchers, need some help with an older SolarEdge Storedge
system. System has 14 kw solar, two 7.6 Storedge inverters and each
inverter has one LG RESU 10 battery. System was installed 6 to 7 years
ago and has worked great until the LG's started acting up. LG replaced
them and in the interim one of the 7.6's went down. SE replaced it.
Everything has been up and running for 12 months, SE did all the
required firmware updates, batteries and inverters when we finished
replacing batteries and inverter.
So, the problem is the system comes out of program every 3 to 5 days
and luckily my customer knows how to reengage it and reprogram the
system ( total consumption ). We have been calling SE Support for
months and it hit a peak two weeks ago. They are telling us we need
shielded 600Volt CAT5 twisted pair wire for all the comms. We have
shielded cat non twisted pair, the wire they had us install 6 years ago
( which has worked just fine. When I asked the tech do I use one or
both of a twisted pair he said just one. I asked what is the difference
from the wire we are using if you are asking us to use just one of each
twisted pair. They could not answer and when asked to get a more senior
tech they said until we had shielded cat 5 twisted pair installed we
could no longer speak with them.
I found some 600 volt, shielded cat 5 twisted pair and installed one
section, from one inverter to it battery. Took forever to separate the
twisted pair, strip one and insert it. System is now Buggier than it
was.
The tech could not explain why the system has worked well for 6 years
with the shielded single wire and after replacing a inverter and the
batteries it is now throwing the programing, just demanded the 600
volt, cat 5 shielded wire.
So folks, my apologies for rambling by both my customer and I are at
our wits end. We have reached out to the head of tech support but only
crickets. Any and all help or ideas appreciated.
Thx
