"Please stay on topic" in ALL threads...do we need that?

I've recommended before...I prefer the preservation of all posts, but off topic posts can be moved to a specific 'off topic' forum (running tally, no context) to keep active on topic discussion on track. Additionally, the originating poster/topic starter (OP) can request 'no off topic', thereby assuming loose ownership and tone of the thread they create, signaling to moderators to more actively manage their threads.
 
Went out to pull some old panels off a pole mount and replace them with new bifacials. Thought I had everything ready, nuts, bolts, mc4 connectors, wire, everything ... drat, 1piece short of channel strut and I'm not making a 60mile round trip to get another stick.

Don't you hate it when that happens.

Yeah, that huge banner is space that could be earning some advertiser dollars for the site.
 
I think the point is to stay on primarily technical topics. I don't mind when my threads veer from one technical topic to another. Maybe you start off talking about fuses and you end up talking about charge profiles and that's fine with me. The OP of the thread can say if they don't want to veer.
 
Hey...
OP as the right to report any off topic posts.
Anything not on topic on posts that the OP does not want we mods will remove.
Please hit the report button... dont make an off topic post saying posts are off topic.
 
Occasional off-topic technical digressions are one thing but all too often it veers off into completely irrelevant rambling.
That reminds me of a story. I had set out to install some new solar panels one morning when the phone rang . It was my neighbor and he needed a hand fixing his truck. The truck was a Toyota which as everyone knows is from Japan. Why is it we import trucks into our country instead of making our own?

Should I use a 15A fuse for the parallel connection? or is it better to go with Bifacial panels?

I mean, we're boomers...complex questions require anecdotes, metaphors and shaggy dogs until we've weaved a novel. lol
 
Yes, I too have been looking at laser engraving heads to add to my CNC mill. Decent ones are still quite expensive.

Asking people to help and then getting bent if they ramble while they help seems quite retentive to me. Sometimes good points come up in the ramble that wouldn't otherwise get said.

I give blanket permission for you to all relentlessly hijack, ramble, or otherwise stray off topic on any thread I start. If I care enough, I know how to redirect the discussion.

I went up on the roof to wire the combiner box. I knew i needed 6 ferrules, so I grabbed 7 "just in case". When I got to the roof, I had 5. Granted it wasn't 60 miles, but it was a 13' ladder and it was snowing and 11pm and 22f outside.
 
How do you all compress your diy lifepo4 cells?
I feel like this topic never gets the attention it needs...
I used 3/8" aluminum plate, 3/8" all-thread covered with 3/8" taigon tubing. On the end I used a fender washer over top of a valve spring out of a 2015-2021 corvette LT4 engine. Cranked down to 10inch pounds for 4 bolts applies the minimum 3000 newton compression. During it's expansion of ~3% the compression increases but does not exceed the maximum of 7000 newtons.
