by

Introduction to Stäubli MC4 Connector Assembly Learning how to crimp MC4 connectors correctly requires more than simply stripping a wire and compressing a terminal. In photovoltaic (PV) power systems, high-voltage direct current (DC) circuits rely on correctly assembled single-pole connectors to interconnect solar modules, combiner boxes, charge controllers, and other equipment. This guide focuses on … Read more

Solar Extension Cable Sizing: AWG, Distance & Voltage Drop

by

Introduction to Solar Extension Cable Sizing Setting up portable solar panels often requires placing panels in direct sunlight while keeping a portable power station in the shade of a vehicle, tent, or shelter. Bridging that distance requires a solar extension cable. However, extending direct current (DC) wiring introduces electrical resistance, which causes voltage drop and … Read more
