My set up, installed yesterday. 5kW array & 6.5kW battery.
So far so good with one or two teething problems. One of the strings isn't performing quite as well as the other. The installer came back today within an hour of me calling them and tested both strings and they're the same and fine, so it might be a set up parameter in the inverter. He's going to investigate further tomorrow. What I'm seeing is one string has a voltage that fluctuates around 130v - 140v (the 'best' string), whilst the other is always at 150v. It sometimes has an output a few hundred watts lower than the 'best' string.
Anyone on here have a clue as to what the issue might be?
