My system will be six years old the end of this month. I have a pair of Quattro 48/5000s that I initially set up to generate 240v. I live pretty far north with short days and lots of clouds. Nobody told me how high the system overhead is when they’re set up that way. So much for 240v, I changed over so I have 120v at the service panel. Since I did this five years ago I don’t really remember precisely all of what I did or why I did it. Note to others: Consider documenting what you’ve done and any changes you’ve made, preferably with photos, so you don’t find yourself in the spot I am right now.
I changed the feed to the service panel so each inverter powers one side of the panel, no problem, this setup has worked well for five years. So why am I asking for help? I use a DuroMax XP12000EH generator to get us through the sometimes lengthy periods of little to no solar we deal with this time of year. This year the generator and the inverter chargers have had problems synching up and I get the dread click of non connection. If I futz with things long enough finally they get together and the wonderful charging light comes on each inverter. I decided I’d go into the software and derate the amperage per leg from 25 amps to 20 amps and there’s where the problem showed it’s ugly face. For a reason I have no memory of I changed the RJ45 cabling from the slave connected to the master and then the master into the CCGX. For some reason I have the RJ45 cable from each inverter plugged into the CCGX.
When I unplug either cable from the CCGX to plug it into the interface so I can use the computer to change the generator setting I get a horrible racket and error messages show up on the CCGX. Obviously I’ve made some sort of configuration error but before I do something stupid trying to correct what I screwed up I thought I’d reach out to them what might know better than I do and ask for help.
