I need a torque wrench or two. Which is your favorite or favorites for solar applications?

[WYtreasure]

I have some nice fancy Snap-On torque wrenches that are electronic as well, both in 3/8 and 1/2” drive, and also do angle which I needed at the time for one of my cars (that sounds like I have a ton of cars haha, I dont). But they’re amazing!

for finer/lower details I have a 2-16nm, 1/4” drive from Effetto Giustaforza, it’s beautiful in its own right.
then for the finest precision, I have a couple Wera screwdriver torque wrenches for fine tuning tenths of a nm.

I like tools

with that being said, I do believe you can get some fairly decent torque wrenches at some low prices. You don’t have to buy snap-on to get accuracy.

Thank you for the information, I will take a look at those nice ones.

I bought a Wheeler Digital FAT Wrench, 15 to 100 inch pounds, 1.7 to 11.3 Newton Meters. It came with a calibration certificate which is cool.
I assume the calibration certificate numbers are just like using the "Compass Deviation Card" numbers?? Yes/No/Maybe so

Would something like those be fine?

+/- 10% accuracy may not be good enough considering that the low end of the range is only 15 inch-pounds. I'm trying to recall how much I tightened the screws in my cell terminals and I think it was maybe only 12 inch pounds.

Guess it depends on what you’re tightening. I tightened my EVE cells to 6Nm.
6Nm is 53 inch pounds fyi

Anyone have a suggestion for a good single wrench for all solar applications that won't break the bank?

 

[Supervstech]

I have this one.
I use it in my main panel jobs, and on battery cable installs.

I don't trust the click type. For the battery connections, a small beam style worked for me.

For larger bolts, I like the Warren & Brown Torque Wrench. It is a beam style with an audible click. Unfortunately, they are Austrialian, and hard to find inthe USA (I bought mine off e-bay).

In general, you probably need two. One for the really low range and one for mid range.
So try to determine your specific applications/products to understand what torque ranges your install will require, especially on the lower range (less than 15Nm). If you don’t need the lower range for your install then you can get by with just one.

Getting everything ready for my first DIY battery so I'm curious about which one of these two would you prefer for the job? It comes down to about the same price after the coupon for the bike wrench.

Thanks.

I used a coupe of click wrenches like this for smaller torque jobs nd the "click" was not very pronounced and I'd miss it.

Of the two, I'd use this even though I've not used one. I actually prefer analog gauges for these small torque jobs, so I'd liek to be able to see what the actual rating is or if this gives an audible beep, hear that.

Yep... you have to 'feel' it... see my posting here (and the sad image above it)

Thank you for all the replies and advices. I torqued the BMS busbars at 7 Nm and the cells busbars at 5 Nm I torqued the compression plate at 9 Nm and the rest manually, like houseofancients said it's less important. I also watched the Andy's video and saw he didn't put the copper washers...

The reviews do say the analog one has a very quiet "click" so I guess a bit risky to go ahead with that one.

I'll go with the digital adapter as you've suggested and will get the YR1035+ you recommended a while back.

Thank you.

I use this set for everything. https://products.wera.de/en/tools_b...icycles_and_e-bikes_bicycle_set_torque_1.html They are a bit expensive in the US so I just order from a german bike shop (bike components). All the WERA tools are amazing; great quality and good value.
