PV1-F vs H1Z2Z2-K: Which Solar Cable Standard Applies to Your Project?

Both types are 1500 V DC PV cables, but IEC 62930 and EN 50618 differ in test regime, sheath compound and marking. What to put on the purchase order, and which one a European tender will expect.

Where most project questions begin

Four notes cover the questions we are asked most often before a tender: which PV standard applies, how an MV collector feeder is sized, how a nacelle cable is specified, and how a battery rack cable is sized. Each one links to the product page it refers to.

Start with these

  1. PV1-F vs H1Z2Z2-K — the DC cable standard
  2. Torsion cable for nacelles — the loop specification
  3. Battery cable sizing — derating inside a container
  4. Collector feeder sizing — 6–35 kV construction
