Hey Guys
I want another string and have been advised on another forum that the voltage difference is too much
1 string of 270w x4 (1080w) panels in series
4x43.6voc = 174.4v.
1080/174.4=6.19a
And
1 string of 375w x6 (2250w)in series
6x48.8voc= 292.8v
2250/292.8= 7.6a
What are the guidelines and is it a percentage of the voltage that can be different (ie within 10% ? etc)
What happens is you have a string that's theoretically matched but is say east facing and live time voltage difference could be significant??
