Guide to Connecting 60 Watt and 90 Watt Solar Panels
Overview:
This guide provides clear instructions for correctly connecting 60 Watt and 90 Watt solar panels used in various TraffiCalm applications. Due to the potential presence of superfluous or confusing terminals within the junction box, proper connection is crucial to ensure operational efficiency. This document outlines how to identify the correct connection points to achieve optimal voltage output and polarity, using a multimeter for verification.
Key Connection Points:
Identify Correct Terminals: Reference the image provided, focusing on the silver stripe on the diodes at the top of the housing to locate the correct terminals.
Voltage Testing: Ensure your panel outputs over 14V in obscured sunlight conditions. Confirm correct polarity by testing voltage across the red and black wires with a multimeter.
Caution and Adaptability:
Supplier Variability: Be aware that our supplier may alter the design of the solar panels without prior notice. It is important to use discretion and verify all connections with the multimeter test outlined above to ensure they are correct.
Incorrect Connection Consequences:
A total panel voltage output less than 12V in sunlight.
Negative voltage polarity on testing.
If either condition is met, the system will fail to charge the connected batteries, potentially leading to system failure within a week to a month, depending on the battery capacity.
