Hi,

There is something to be said for staying with one "family", so do check out the prices at Imarine for Magnum charge controllers.

Victon is top drawer stuff. AM solar would not be where I would buy a controller, or panels.

I appreciate what you're saying about sticking with Magnum and regret not buying this controller initially. I got my MSH 3012 at Imarine; great place.

At this point, going to a single controller of any brand might be brain damaging, but I'll crawl into the fifth wheel tomorrow and see if it's possible given the space. Given where a single controller must go, I may not even have enough wire to get both arrays over to it, bla bla bla. I'll get in there and see tomorrow. If I can do it all myself, the magnum controller is only $150 more.

One reason I didn't use the magnum was it's physical size. My entire system is installed just behind the bulk head (the wall where the stairs go up in a fifth wheel to the upper bedroom). I moved water pipes, hvac vents, etc. and did specific carpentry work to provide for my system's install between the bulk head wall and the "garage" compartment wall in the fifth wheel. It's tight, was a pain to install, but my goals were met. This location provides a superior mechanical advantage in terms of weight distribution in my rig, since I had ample capacity in the trailer and little in my truck payload, plus my most forward compartment is not filled with equipment, and it's more secure and within conditioned space. That its so close to the living area also makes controllers with loud fans, like Midnight Classic, less desirable. Don't know about the fans in the magnum.

I'll scope out space and go from there. Thanks

I use Morningstar Corp controllers. Instead of using their remote meters, I took advantage of their ability to communicate with the MODBUS protocol. This is the same protocol you find in OBD II that is used to retrieve codes from your vehicle's computer. MODBUS is a widely used industry standard communication protocol.

Here is an example graph of what I can see from my controller's point of view. I have more graphs.

I use a Raspberry Pi to collect this data at one minute intervals. The graph is summarized to the hour.

You will need to read my profile for a description of my systems. I have two systems; one in the Van, and the other in my TT. The graph is from the Van's system.

Most awesome graph I've ever seen to understand this process. Well done.

Hi folks. Just wanted to follow up on my thread. I bought two MPPT Victron 100/50 controllers from AM Solar here in Eugene, Oregon. I was able to stop by Eugene so this was great. Yes, I paid a modest premium of $80 (total for both) over the "internet" price, but got a sit-down consultation with an expert, printouts of the recommended settings for the controllers AND my Magnum MSH 3013 inverter, plus the manager's business card, whom I could call with questions during my installation, plus installation advice and I did not have to wait.

I'm a fan of AM Solar, even though I know that shop isn't cheap.

As a novice, I installed it all myself, including getting the app on my phone working; a no brainer, and they work GREAT!!!!! The Victrons went onto the board right where the two BZ Products controllers had been, with NO additional wiring or rework - nothing, especially since the Victrons may be monitored using a simple app for my iPhone!

I'm just getting around to testing the Victrons, so I ran my bank down a couple hundred amp hours last night, and I'm pulling in 16 amps (total) and it's not even 9am yet; these things are great.

Now, I'd have gone with the Midnight Solar Classic 150 if I had not been already wired up for a stacked system, but love these little 100/50s.
