Hi,

I am new to this forum. I just purchased a FWC Fleet Shell last week and am looking to install a Victron SmartSolar 100v/20a charge controller. My Shell has the flush mount stove and furnace and two 12vdc batteries. I was thinking of installing the controller in the battery box next to the batteries on the rear wall since it is 1/2 inch plywood with the gray finish on it. The controller will just fit between the battery and the rear wall. 

 

The spec sheet for the controller calls for it to be mounted on a "non-flammable substrate". That has me a little concerned about mounting on the inside of the battery box. The advantage to mounting there is that the wires coming from the outside connectors for solar panels end inside the battery box. Also the spec sheet mentions that the ambient temperature of the controller should be within 5 degrees C of the batteries.

 

I am planning to use a 200 watt panel so I guess I could use a 75v/15a controller. I was not planning to use the load control part of the solar controller.

 

Do any of you have experience with Victron solar charge controller and have any recommendations on installing one? Any pictures you could share?

 

Thanks.

I have two 120W commodity flex panels on the roof run in parallel. My two batteries are run in parallel. I would suggest the 100/20. It’s nice to be able to add, & have options, if need be. Yes, as Vic says below, more is better. My Grandby Shell cabinet was tight but doable.

Thanks.

Do you have room to put about 1/2" of washers or some kind of metal tubing around the mounting screws?  That's what I did.  But honestly the unit does not usually run warm, never mind hot.

 

Go bigger rather than smaller, if you have the space and $$$.  75/15 is borderline with the 200w panel.  200w * .85% efficiency / 12V = 14.2A.

Thanks Stokeme and Vic. Very useful information and eases my mind. I'll go with the 100/20 and see if I can put some spacers on the mounting screws.

I have the 100/30 and it never feels warm. Mine is mounted to a cabinet side panel with bolts and I spaced it away from the panel with a stack of washers.

I just upgraded my 2016 Fleet from a PWM controller to the Victron 100/20. I have two 75ah batteries and two 100W flexible panels and I may add a 100W portable to the mix, which the 100/20 will handle.

 

You might also consider adding a Victron battery monitor while you are installing the controller. As many on this forum have done, I installed the Victron BM-712. Wish I had done this 4 years ago!

 

I don't know what electrical appliances you currently have or are planning to add (e.g., additional lights, 2-way fridge, furnace, inverter, etc.) and how you plan to use your camper (i.e., mainly weekends vs. extended trips) and in what conditions (i.e., mainly summer vs. shoulder seasons or mainly sunny vs. shady, rainy, cloudy, snowy conditions). The ROI on the monitor be higher if you camp for extended periods and/or in more variable conditions. Having a good monitor will reduce the guess work and allow you to learn how to manage your batteries and electrical use, and also trouble shoot problems. It's a pretty easy install (once you figure it out) and as per above, you'll find lots of help on this forum.  Enjoy your camper!

I have the Victron 100/20 in my Hawk. Using the output is nice to see what you are using.   Victron also has a great Bluetooth app for your phone to monitor what is going on.

Bill, you have the Victron BMV too, right?

No I am just using the App. I do have a voltage meter that I put in when I did my build.

OK.  So, there is an App for both the MPPT controller and the BMV.  Just clarifying ... because it is the BMV that tells you your battery SOC, not the MPPT.
