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...

I think removing the display with all the buttons would lower the price by what Rogue remote monitor costs, about $100 as I recall. Didn't matter to me, and still doesn't - too much - as there is no need to look at the Rogue display more often than once a day, if even that. A monitor even as good and informative as on the Rogue, won't provide as much information as a dedicated battery monitor, so - yes, it's better to get a display-less controller and a good monitor, but this would cost a bit more than a controller with on-board display. So for those penniless but wanting a good controller the current iteration of Rogue will do.
I can understand DW not wanting such piece of equipment inside, and would rather prefer black enclosure of the previous model, it blends in the interior better. With space constraints of an average rig anything bigger than 4x4" flat monitor panel is too big. Wires can be hidden in wire raceway for a foot or two needed from the wall to controller.
BFL... Different wire length and different voltage drops can NOT cause different readings of controller display VS multimeter. Controller has a voltage sense wire that eliminates the voltage drop and makes controller see the voltage as if it were clamped on the battery terminals. Or is supposed to eliminate. Multimeter has regular leads about 3ft each, they are not supposed to cause 0.1V drop as the meter draws very low current, and even if they would cause the drop, the meter would read HIGHER than the battery terminals or than the Rogue, but it reads lower. Will try and check the meter properly upon return to civilization, and until then will leave it as is.
