    JB Weld versus Loctite for grubscrews

    I went for the conductive epoxy, it placed nicely, squeezed up completely around the stud threads. I ordered 3 packettes, as I didn't know how far 2.5grams would go. Turns out one packette did 2 batteries (16 total,studs). Now I have two unused packettes..have no idea what I'll use them for...

    Why don't people use large 400w Panels on travel trailer?

    Here's my one 400w Trina (80"x40") mounted on the 1-5/8" aluminum unistrut. 41" ecoworthy tilt brackets. Had to do quite a bit of trimming and drilling to get to this point....getting all the correct stainless steel hardware, etc. I'll take the panel off the completed bracket, then mount the...

    Why don't people use large 400w Panels on travel trailer?

    I'm doing 3 x 400w Trina panels. Only One will have tilt function. 2 mounted flat, each flat mount will have 8 brackets. Tilt panel will use aluminum unistrut and 2 sets of ecoworthy tilt brackets (4 total). Am thinking to use wind deflectors on leading edge of panels.

    Strut channel for roof of RV

    Yes, I think 10ft is largest. It would have been $115 to ship just these two pieces to my location. So had it shipped to nearest Grainger location for free....and drove the 1.5 hours each way. It was delivered to the Grainger location in like 2 days!

    Strut channel for roof of RV

    Picked up my aluminum unistrut from Grainger today, very quick! I only need 79" to mount my tilt panel, but thinking to mount the entire 10' pieces for possible future needs...went with the 1-5/8" tall to give me a little more space under panel to reach in and unscrew thumbbolts for tilt deployment.

    How To: Mount Panels to an RV Roof

    Did you pre drill, or just drive the #10 screws in? #10=3/16", I've got some really nice #14 (1/4") self tapping metal to wood screws with a sealing washer backed up with a metal washer. They are for fastening metal roofing down. They fit perfectly centered in my bracket holes. I'm thinking a...

    Lock washer, nylon nut, locktite - how to keep the panels from flying yet keep the ability to tilt?

    I purchased the 41" Ecoworthy setup for tilting. In fact, Two sets (4 total jigs) for one 80"x40" Trina 400w panel. I'm mounting 3 such panels but only one will be able to tilt. They come with M8 Thumbwheel- headed bolts. Using regular M8 bolts at the two hinge points with nyloc bolts tight...

    Strut channel for roof of RV

    I'm using 3 x 400w Trina panels (80"x40") 2 will be flat mount, one tilt. Using two sets of the 41" Ecoworthy tilt kits for the one tilt panel had to modify them a bit to allow the entire thing to fold up without removing the short support piece. I will get some of the same aluminum unistrut...

    Want to paint Trailer Roof before mounting panels

    It's wind season in the Desert Southwest, keep those awnings undeployed! Gusts only in the 30s today, started beating my trailer up around 2am. Had to go and close my truck hood, I leave it propped open at night to discourage rodents setting up home overnight (in addition to anti rodent products...

    Want to paint Trailer Roof before mounting panels

    I studied the Dicor 2 part system, its acrylic based. Acrylic not the top material from what I can read, seems most have 3-5 years and its time for recoat. I'm still leaning towards the EPDM Coatings butyl coating as its 20mil thick and seems lasts 10 years or more. They have 30 years of...

    Want to paint Trailer Roof before mounting panels

    Thanks for suggestion. Silicone supposed to be best IIRC. Have you or someone you know used this product on an RV EPDM roof? I'd like some proven success. I'm a little hesitant to use something without years of good results on an RV. I'm sure it's a great product for use as intended on...

    Want to paint Trailer Roof before mounting panels

    If be afraid to try it on a rubber membrane. The Acrylic ( Dixie), Butyl Rubber (EPDM Coating) or Silicone based coatings are what the industry uses for rubber membrane roofs. For a metal roof, it might work, I know it also adds quite a bit of weight, not sure if it would handle the twisting and...

    Want to paint Trailer Roof before mounting panels

    Nice, its so windy here constantly, like 40-60+mph gusts and dust devils can spin up out of nowhere, that I'm hesitant to have any deployable panels. It shakes my trailer so bad, it's impossible to sleep when they come up in the middle of the night. I had my truck hood open just an inch or so...

    The flat roof was rubber sheet? I'll have to look into that product if it's available in Kommifornia.

    Want to paint Trailer Roof before mounting panels

    I'm still debating mounting one panel on a tilt system using 2 sets of Ecoworthy 41" tilt brackets. The other 2 would be mounted standard using those 2 piece brackets. I'm leaning towards the EPDM coating as its rated best, butyl rubber. The Dicor is acrylic. The EPDM coating can't be shipped to...

    Want to paint Trailer Roof before mounting panels

    200 sq. ft. Rubber roof membrane. Intend on mounting 3x400watt Trinas (80"x40") It gets hot up there under the panels! Roof Membrane gets cooked. Was thinking to have some tilt mounts, but seems dealing with such large panels, a flat mount might be best way to go....KISS. Regardless, want to...

    Am I crazy to put a 1760W solar system on my RV?

The only ones I've found wide enough are the 41" Eco-worthy https://www.eco-worthy.com/products/28-41-length-adjustable-solar-panel-tilt-mounting-brackets ..and instead of just the pair of brackets, I'd...

    LiFePO4 Battery Warmer Install

    thanks, sent them messages. Hey did you ever consider using the relay functions on your Victron Energy BMV-712 Smart Battery Monitor As a heater switch? I have the temp probe on my 712 and seems reasonable to try and use the switching function. Not sure yet how.......
