Hello all!

Just a quick question. What is the maximum distance from solar strings to combiner box, (if any)? I'm adding (4) 245w panels in series-parallel (2x2) and working on the layout of the design. Any input would be helpful.

Thanks!

I didn't create it, one of the folks around here created it and gets the credit for this Voltage Drop Calculator.
