I'll have to get back to you on that over the weekend. I'll been doing this system a little at a time. All panels are used. First year I put up 14 panels ( two strings of 7) ( they were around 37 volts each , maybe 230 - 250 watts ) with a Growatt 3000 system. Second year I replaced the Growatt...

Thank you, thank you, thank you. I just ran into this exact problem today when I tried to add a new EG4-LL-S battery to my existing battery stack that included EG4-LL version 1 batteries. I didn't use the software that was pointed out here, but instead just made my own cable with pin 6 removed...

I currently have a EG4 6000EX with a max PV input voltage spec of 500 VOC. I set of my panels so that I have an open circuit voltage of 475 and a working voltage around 385. I'm thinking of taking advantage of the Signature Solar upgrade program and trading the EG4 6000EX for the XP. I noticed...

Say it tickles the 480 VOC , will the unit be damaged, or just generate a code and shut down?

Thanks for the information. A bit harsh, but appreciated all the same. I'll be shifting one panel from a string to a different string to bring the VOC down a bit. While I get the cold temperatures are an important concern, it does seem really distant when I'm running my A/C unit 9 months a year...

If the spec is 480 VOC, what is the reason for keeping the VOC below 400? I understand having a safety margin, but an 80 volt safety margin seems excessive. Have you seen problems going over 400 VOC? I'm trying to keep the system voltage as high as I safely can to cut down on the current that...
