  • Branches = nn / 11 rounded up (max inverters / branch)
  • Micro-inver/Branch – nn/ Branches (adjusted for design)
  • Cable size VA / 240V *1.25 – (See https://www.southwire.com/calculator-vdrop)
  • Breaker next larger size from nn*1.45A*1.25 (IQ 8A max current) (must be compatible with cable size)
