When everything is connected - there is some solar charging happening and the generator powered charger is running: The red+ lead between the panels and the solar controller measures a negative current. (huh, why?) But when the red+ lead on the charger is measured between it and the batteries, it shows a negative current as well.
SunPower used to make only positive ground solar panels. Due to very technical reasons, they were more efficient. They needed a positive ground charge controller to use them. They make negative grounded panels now, I can't think of any reason to use a positive grounded controller these days.
The article explains how to determine the positive and negative terminals of a solar panel, crucial for proper installation to avoid energy wastage. Methods include examining the diode and using a voltmeter to measure voltage. It also discusses checking solar panel polarity and fixing reverse polarity issues.
The positive lead is on the negative terminal and the negative lead is on the positive. If the voltage is a positive number, then the polarities are correct. Either of the results tells you the polarities of the terminals. What Are The Different Solar Panel Connectors?
A charge controller regulates the voltage and current flowing from the solar panel to the battery. It is crucial to ensure that the voltage output of the solar panel matches that of the charge controller to ensure optimal battery charging. Therefore, you should evaluate the charge controller before selecting a solar panel voltage.
For instance, monocrystalline and polycrystalline silicon panels tend to have a negative temperature coefficient, meaning their voltage output decreases with rising temperatures. The amount of sunlight that reaches the solar panel directly impacts its voltage output.
