I have just recently install a Noma 100W panel and controller on my trailer. Chargering 2x 6V batteries. I plan on buying a MPPT next year but that's a different story.
Question is this. I bought two monitors. Installed one to track solar input. Installed the other to track battery bank discharge power used.
I got a total of 196Wh drained from the battery bank, and 891Wh inputed from the solar panel. My batteries stayed at around 12.7v for the 6days we camped. I let them sit with no load for a bit before checking the voltage. First trip with the setup, I am a data guy so I watched the numbers alot. I am very happy
But, why such a big discrepancy between the two numbers?
Any thoughts are welcome.
