Learning how to wire solar panels requires learning key concepts, choosing the right inverter, planning the configuration for the system, learning how to do the wiring, and more. In this article we will teach you all of these, saving you weeks if not months of hard studying on the subject.
There are two basic approaches to connecting a grid-tied solar panel system, as shown in the wiring diagrams below. The most common is a "LOAD SIDE" connection, made AFTER the main breaker. The alternative is a "LINE OR SUPPLY-SIDE" connection made BEFORE the main breaker.
Main options for connecting photovoltaic system to an electrical installation: (1) to the main LV Switchboard; (2) to a secondary LV Switchboard; and (3) upstream from the main LV switchboard. 1. Recommended design: connect to the main LV switchboard.
A solar automatic transfer switch allows you to use a PV system alongside a backup power source. Easy to install, it also offers the advantage of automated operation and a safer switching method between your solar system and an alternate power source.
