Normal Condition: In most cases, when the inverter is off, there should be no voltage between either DC conductor and ground (i. . Calculating voltage drop in PV circuits is a critical skill for ensuring a solar installation operates at maximum efficiency and safety. For any journeyman electrician or master electrician working with photovoltaics, correctly performing a wire size computation is essential to prevent significant. . With a multimeter with one lead on positive or negative the other lead on ground (earth) I show voltage. I have also used a oscilloscope to see the wave form and it has a very odd wave form. Every foot of cable between your solar array and inverter acts as resistance, stealing watts from your energy harvest. While some drop is unavoidable, excessive voltage drop can starve your equipment of the power it needs to function correctly, leading to. .
