Does a conversion ever get done? This morning I decided to post some pics and info on my solar system; I want to call it done, even though it probably isn't. I'll go over what I've done to it first.
I originally put a single 100 watt Renogy solar on the roof rack, and I was going to try it. But then after talking to people here, a single panel seemed like underkill (is there such a word?). With just one panel I had noticed a marked improvement with the van's interior temperature (it is shading the roof after all) and since it seems like overkill is difficult to achieve with solar panels, at least on a small van, I decided to add a second panel:
The roof rack normally comes with just two cross bars but I had already gotten two extra cross bars from my friendly neighborhood junk yard; I mounted the second panel exactly like the first. These two panels completely fill the roof rack so if I needed to add a third it would have to be installed in front of the roof rack, over the cab.
I also decided to replace the charge controller, I got an EPSolar VS2024BN which as near as I can tell is the same thing as the ViewStar and the Renogy LCD. Before buying it I went to the EPSolar website and downloaded the Operation Manual for it, it's pretty impressive being able to configure everything (a little too impressive as you'll see in a minute). The charge controller is a simple swap with the original Renogy PWM charge controller though two of the mounting holes needed to be relocated. In ten minutes the VS2025BN was in place and working:
The first thing I discovered was that unlike the Operation Manual the actual EPSolar VS2024BN has no user defined battery charging profile! That was the frikkin reason I bought it! I decided to muck around with it anyway since it did have a built in meter and could display volts and amps from the solar panels, into the battery, and to the 'load', which put it way ahead of the Renogy 30 amp PWM charge controller. As I was scrolling through the charge phase settings I noticed that some could be altered, then I noticed that the 'Gel' battery type didn't have an equalize phase (which was what I wanted). So even though my battery is an AGM I set the type to 'Gel', set the 'Boost' to spec and set the 'Float'. Even though the 'User' defined battery type was missing, my immediate concerns taken care of and I could do all that I wanted using the 'Gel' battery type. I bought the VS2024BN with the remote temperature sensor so I taped it to the side of the battery. It's a work-around, NOT a fix.
I am in communication with the seller about this discrepancy with the 'User' battery type. One thing I noticed when I looked at my pictures is that even though I bought a VS2024BN charge controller, what I got was a VS2024N. I am raising this point with them...
