API field
Global wiring resistance
Resistance of one inverter's DC wiring, seen from its input
Unit mΩ per inverter
What it is
The resistance of the whole DC wiring network of one inverter as seen from its input, given directly instead of the loss fraction; when given, it replaces the loss fraction. The field is in milliohms; the API takes ohms. Empty derives the resistance from the loss fraction.
Typical values and how to get it
From the cable schedule; otherwise leave it empty. The derived value is the loss fraction times the array's maximum-power voltage over its maximum-power current at standard test conditions: 1.5 % on a 1,000 V, 1,000 A input is 15 mΩ.
