So, from that, power can only flow in one the direction - from the SSR L1 to the SSR L2, but I''m not sure if I could put them on both the positive and negative PV wires? I would have the positive from the panel string go to the Pos SSR L1, and the Pos SSR L2 would go to the pv pos on the inverter.
Understanding DC Power Supplies – ITP Physical Computing
Testing your power supply. It is always good practice to test a power supply before using it for the first time. The example below will show how to test a power supply with positive polarity. If you have a negative polarity power supply, then you will get a negative reading. You should then switch the position of the multimeter probes. Figure 5.

Learn how to identify the plus and minus terminals of a solar panel without polarity labels. Use the diode stripe, a volt meter, or other methods to test the polarity of your solar panel.
How to Tell Which Way Round a Diode Should Be: 7 Steps
An LED is a light-emitting diode. Turn the multimeter to the Diode setting. Place the positive lead on one of the pins, and the negative lead on the other. If the LED lights up, the positive lead is touching the positive pin (the anode), and the negative lead is touching the negative pin (the cathode).
Battery Positive and Negative Side: Explained and How to Identify
The negative pole is often the larger terminal and can be identified by its negative symbol or a minus (-) sign. Understanding the characteristics of the negative side of a battery is crucial in determining its proper installation and usage. Incorrect connections can lead to ineffective power supply or even damage the battery.
voltage
My lab only has single supply power supplies (only offers positive voltage). I know that I can reverse the polarity and achieve a negative potential, but this means using multiple power supplies. (I am pretty sure that I cannot reverse the polarity on a single rail to fulfill both my negative and positive potential needs as this will cause a ...
