Customer ServiceThe line side method requires your solar provider to work with the utility to disconnect your facility from the transformer (the typical connection point between your business and the grid) before the interconnection process can start.
There is an ALTERNATIVE UTILITY CONNECTION called a “Supply or Line Side" connection. This connection is made BEFORE the main breaker. A junction box is added between the utility meter and the main service panel. Then the wires from the utility meter, the main breaker panel, and the PV solar are connected in the junction box.
The process of connecting a solar PV system to the larger electric grid is called interconnection and it’s often the final step in the solar panel installation process. The physical connection between your solar system and the grid can be made either with a line side tap or a load side tap. If you have no idea what that means, read on.
The technique for supply side connections involves connecting the solar system directly to the service entrance conductors through a dedicated utility meter or disconnect. Key to this process is the utilization of appropriate junction devices that can safely manage the parallel connection without interfering with the utility’s operations.
Wiring solar panels in series requires connecting the positive terminal of a module to the negative of the next one, increasing the voltage. To do this, follow the next steps: Connect the female MC4 plug (negative) to the male MC4 plug (positive). Repeat steps 1 and 2 for the rest of the string.
The total output voltage and current of your array are determined by how you connect the individual PV modules to each other and to the solar inverter, charge controller, or portable power station. Even if you don’t do any harm, a smart solar panel wiring plan will optimize performance and maximize the return on your investment.
