Install the wire box before the string inverter

Contractors can install string inverters with integrated, but separable, wire boxes more efficiently by installing the wire box first and then focusing on the inverters. Employing the appropriate skilled workers to align all wire boxes is essential to quickly complete DC and AC wire termination and connection. Once the wire boxes are in, less-skilled, lower-cost

Avoid mis-wiring an east-west array

As east-west arrays become increasingly common, they bring an important additional requirement: The modules on the east and west orientations need to be wired to different inverter MPP zones, or different inverters entirely. This can slow down electrical installation and, more importantly, create opportunities for installation mistakes. These mistakes—specifically, when east- and west-facing modules are

A solar farm’s balance of plant also needs O&M attention

By Judah Moseson, PE CEM, vice president of operations, Cooke Power Services The balance of plant (BOP) is the most important link for delivering power produced by a solar farm to the marketplace. The BOP consists of the pad-mount transformer at the exit of the inverter through to the collection system and substation. The BOP
