Rogue MPPT, 490W and charging mysteries
Now that we were finally all in one place - me, Rogue 3048 and my rig - it was time to have some fun. 1)Battery: old starter, tested beyond dead, plates above the water. No wonder, 8 months in Mex...

Full Mosey,
I am going to follow the advice of Smkettner and keep the batts on Float for some time, so they would "wake up" and hopefully behave more like they should. Also, to watch the Tcomp and fine-tuning it with VRIM if necessary. Light use in daytime like charging laptop, running shaver, radio, etc with that much solar doesn't cause batts to cycle - voltage drops but they remain in Float.
It's funny. On another forum that isn't solar friendly I tried to explain that once in float that my panel provided the power to run things like my furnace or even the coffee pot without taking the battery out of float. They told me NOTHING can run off the panel and that the battery is discharging and being recharged so fast that neither the controller or my DVM could see it. So I started a load and removed the battery while the load continued to run. They were not impressed. lol
