2 things, one buying a pair of 6500EX's, the second was not installing a second conduit thru the cement foundation on my array. The latter will require having conduit on the outside of the cement where it can be hit by a lawnmower. The second conduit is for expansion and ability to run wires to a central point before running 420 feet to the charge controllers.
I did buy a combiner box once upon a time, never used it. Maybe someday. I guess that makes 3 mistakes.

That I started with solar at the end of 2022 when prices were at all time high.
It takes half the cost to do the same thing now.

Catch, make or grow everything you can.
But you learned so much! and your two years ahead compared to starting off now!
Yeah not much hookups happen on DIYSolar Forum.Signing up on some DIYSolar Forum... so much of my time wasted I could have been meeting girls...

For sure. I have no regrets in that regard, worth every cent spent.

The time i shorted two 2p16s ( 600a each) by letting my wrench slip..
Must say that did make for some nice fireworks, but also almost made me wet myself

I started big but it is a little demoralizing for every step to take so much money and time. Going on a year of serious effort now and I haven't generated a watt of solar power yet. 6.8kW inverter installed, 20kWh battery done, MPPT is in place, concrete footers for Brightmounts are done, trench is done and filled, 8x 480's are here on a pallet. Just gotta run the metal conduit under the crawlspace and it should all be able to finally happen this spring!

Not buying extra panels when I found a good deal and then couldn't match them when I wanted to expand.

Solar Joules are catch and release
Last summer I put in two GoodWe 7600W grid-tie inverters just before my “condo assn” disallowed net metering. Now I’m installing EG4 ESS stuff to comply. Very expensive mistake not to have planned ahead for batteries.

What's in a title?
Top balancing my second or third set of cells fatigued and a bit complacent I reversed polarity on one of the cells. It made some awesome sparks, melted a stud and scorched a bus bar. I gained a whole new appreciation for the amount of power on tap. Cells are still in service today with no issues.

Good thing it had reverse polarity protection

I also shorted both battery and inverter while tightening inverter battery lugs on a growatt all in one .
Using non insulated wrench.
And apparently didn’t turn off breaker .
Batteries. And panels are the last things I connect after that incident no matter how careful or sane I am on any day.
Had to pry the wrench off the nuts of the inverter lugs after
Apparently it still works though.
