I'm Here, But I'm Not All There
I'm adding another string to each array. Which means I will out grow my 2 Midnite Solar 3 sting combiners. I'm upgrading to a Watts247 8/2 combiner
Problem is, all PV wires (strings) go into conduit and into the attic and into the MS combiners. But with the the addition, the existing PV wires will be about 2 ft to short-term. They were all cut to length.
How do I lengthen these wires? MC4 connectors could work but not ideal because I want to stay in conduit. Or at least add a junction box. I also don't think wire nuts is a good option. What would you do? Copper Split bolts? 2 screw busbars? Something else?
