I have a installation with the following equipments:
12 Quattro 48/10000
6 fronius sumo 12.5
48 batteries of 1440 ah ( 2 strings in parallel)
1 color control gx
This installation is also supported by a generator of 120kW
Since it was installed, it appears apparently in random the error 17. This error appeared at several different time of the day and with diferente equipments working, ie, just supplied bu batteries, just supplied by generator and just working with the fronius.
The strange this is that for some time it works for 1,5 days and other just for 2 hours.
I’ve check the comm cables and the length of the dc cables are quite short, max 3,5 meters,
Can someone please advise and help me ?
I’m from Portugal by the way.
