MTS-CB brackets and adhesive WARNING

Posted by dana

Oct 1, 2018 at 1:16pm

Just a heads-up that your MTS-CB installation instructions should include a note to pretty aggressively rough-up gluing surfaces with course sandpaper. They're too smooth. I used a scotchbrite on all surfaces and Sikaflex 252 adhesive, but still had two solar panels blow off and get destroyed. The adhesive came loose between the MTS and the panel on all 6 locations. I'm bummed. This will be $$$$ to replace. I just noticed they were missing as I was headed out of town.

Thanks

I really doubt that any glue would hold a panel on a roof for very long going down the road... To me that's very dangerous for people on the road behind you..... They should be bolted down or removed during transporting and reinstalled when your not in motion....

I think if you were to use 100 grit to scuff all surfaces and let it cure for about 10 days you MIGHT be ok for while

I would never trust it nor would I trust being behind someone with glued on panels or in front of them for that matter

Nothing but a projectile if you rear end the car in front of you

Bolt them down

Agreed. I just purchased what was recommended for the application of the rooftop mount. I sourced the specified Sikaflex adhesive (not cheap) because I wanted to be sure they would stay on. I ride motorbikes and am hyper-aware of people not strapping down their loads, which makes this all the more distressing. Anyway, that's the reason for my post ... when I reinstall I will definitely be screw-mounting. Thx

I ride motorcycles and I have for 45+ years and I makes me cringe to think that someone would even think that glue would hold a panel on a roof of a motor home or camper..... Drill a hole in the roof that's the way to go...

The best place for sealer is your local RV or boat parts store.

Tell them you have to drill holes in your roof and they will fix you right up.

Renogys cable entry box gives no accommodation for screws so they need to be glued on.

There is no chance of it becoming a projectile because both cables hold it also.

The sika takes a very long time to cure and I needed the van mobile so I used a product called 'white marine tex'. Its stronger than the box, maybe even the sheet metal.

I also ride and any one encouraging people to glue solar panels on their roof and drive on the highway needs to rethink that idea.

Please

Thanks. Yes, the Sikaflex 252 adhesive Renogy recommends came from a local marine supply. There are some pretty high-tech adhesives out there, so I was assuming this was appropriate for the job. Remember, even some cars are assembled with adhesives rather than welds these days, so the idea isn't that crazy. That said, I'll be using screwed mounts AND adhesive for this next round. We get some pretty serious cross winds in the Utah desert.

I used the Sikaflex 252 for the cable entry box and finished it with some self-leveling sealant, and that seemed to work well.

Yes you are correct... But the difference is air doesn't get under a fender or what ever it's closed in.... If you have a wreck and the fender is hanging out so that the air can get under it, Even it will blow off the car....


If Renogy is telling people it's ok to glue a panel on top of a moving vehicle I see a lawsuit in their future....

amsolar must be due a law suit but none of their mounts have left the roof

Roof Attachment
Fiberglass roofs – We have been using a type of 3M double-sided tape on our mounts since the mid 1990’s, and we have never lost a panel. As long as the tape is properly installed on a clean surface at the correct temperature, it will hold. As an added level of protection, we use a layer of Dicor self-leveling sealant around the entire perimeter of the mount, and cover the screw holes/heads as well. The sealant protects the tape and any potential roof penetrations from water intrusion and decay.

Good point.

A friend owns a body shop and said he hasn't welded a panel in years

2 part epoxy and no heat distortion from the welder


Personally I would glue a quarter panel but screw a solar panel

Well tattoo, guess you just lost all your brownie points with Renogy because the MTS-CB mounts sold by Renogy are designed for drill free application. I have my MTS mounts glued to the roof and used screws to mount the panels.

If I do then so be it.... My life as well as others are worth way more than brownie points to any company.... If they are glued all the way around the panel to the roof that would be ok.... There are way to many ways for it to fail for it to be safe....  LOL Hell I bet they didn't even include detailed instructions to show how to do it, they don't with anything else...... If so that's a first....


I bet the same guy that came up with the idea to glue panels with just 4 4" spots to the roof of a vehicle is the same guy that decided that a wire lug on a temperature sensor would be a good idea....


Do people even think about this shit before they say that's a great idea???

there is no need to spoon feed when it is in the manual.

So instead of looking up battery type user you just say I don't have that, well you do have that and it is documented.

fusing is to prevent an over current situation that the wire can not handle, 10g can handle 30A forever, an over current may cause the wire to overheat and cause a fire, with mppt your input current is ~10-12A max (2 5A strings) and the output is 40-60A max, the input and output wire should be different size so one would never fuse a 10g wire with 60A fuse!

So far... I've bought at lease 20 items from Renogy and only 3 things had a manual with it and it wasn't the two CC I bought....


Yes I know they are on line but that's not the point... Even then most answers are vague like your answers....


Also since you brought it up....  There is 3 things that you have to change to change the Eq setting not 2 like you said... So I guess you need to read the manual....

This is a correct answer not your half ass riddle answer....


So you would have to change Charge Limit, then Over-Voltage Reconnect, then Equalize Charge. For example:

Over-Voltage Disconnect: 16V
Charge Limit: 15.4V
Over-Voltage Reconnect: 15.4V
Equalize Charge: 15.1

In that order.

Actual instructions for the MTS-CB will differ on application and environment. This is why we can only provide general guidelines for putting together some of these components. That said, we will take this experience into consideration for future product improvements. Our only recommendation is if you have a case to discuss, please contact the technical support team.

This is a snippet from the manual:

NOTE: These instructions are to serve as a simple guideline for installing the corner
bracket mounts. Actual installations may vary with adhesive type or roof type. Consult
your adhesive manufacturer for proper instructions of ABS plastic to a user defined roof
material.

Recommended tools to have before installation:
 Assembly Adhesive (Sikaflex-252)
 Caulking gun
 Masking Tape
 Hand Pads (Scotchbrite Pads)
 Spirit Level
 Tape Measure


All the best,
-Renogy Team

My landscape lights (5x1wx3hrs/night) and 7ah batt don't need mppt, nor does a 200 watt RV system, having some sort of display is required for me.
My first $8 controller was fine, then $40 with display was just as fine and now the $50 grape with blue tooth, all three have default set points that suit me.
