The thing you are all overlooking is the fact that the panels were not properly installed and this caught someone's attention. If you would of left them on the ground you would have been fine.

Added bonus is you can heat the shop at the same time...lol

Grid tied in my area pays zero...plus they require a 1 million dollar insurance policy incase one of there guys gets fried.

99 percent of my tools are battery powered (ryobi), except for mt table saw. Even the riding mower is a ryobi 48v

I actually has someone in my neighborhood say "since you have solar, you but be a Trump supporter"... WTF

Pm me after the first of the year if you still interested.

Thanks y'all. Since my system is off grid, the 6000xp would be the better choice. Anyone want to buy 3 Growatt spf5000es...

so why would I buy one EG4 18KPV @$5600 vs buying four of the EG4 6000XP for about the same price?

found this on Amazon... anyone know anything about them. ExpertPower 48V 100Ah

Holy crap

Battery #1 negative to bus bar, positive to #2 negative. #2 pos to #3 negative, pos to #4 negative, #4 pos to bus bar. All 3 banks wired the same. According to the date code it was one of my oldest ones... bought new in 2015

Yes bank 1 & 3 tripped

See the pictures above...the first one is #2 and the second is #3. Updates to follow

I got the bank torn down and here are the voltages...bank 3 is the one that melted. Bank 1 Battery #1 12.48 Battery #2 12.37 Battery #3 12.56 Battery #4 12.58 Bank 2 Battery #1 12.7 Battery #2 12.37 Battery #3 12.56 Battery #4 12.73 Bank 3 Battery #1 12.79... looks good Battery # 2 9.3...

I had 100 amp breakers between each set.

I will report all voltages when I do my teardown... but I am not planning on keeping them. I want to replace the whole bank with lifepo4's

All terminals were clean before this happened. I also check things daily.

Charging is from solar only. Just about 14k... 3 gw spf5000es and one outback fm60 cc. To be clear the .5v or less was between banks, not individual batteries.

Thats why i wanted to replace the whole bank

Yes, all batteries were within .5v of each other

That is the exact one (3 actually) I have.

3 banks of 48v... the first one you have listed. Each 48v bank had a balancer on it. The balancer is for 4 batteries ea.

That was my thought also.

Clean and shiny. No build up of corrosion.

Melted... its hard to see but the terminal is pretty much gone. Battery Breaker popped and my ups's started beeping

Battery #1 is toast. Battery #2 looks better. Have not checked voltage yet

Right now I have everything shutdown, until I can figure out what happened. I don't want to buy just 2 more agms... although I think the 2 that died were my oldest.

I am running 12 each 12v 200ah agms wired for 48v 600ah. 2 of them just melted... I want to replace the bank with lifepo4... what would be the best replacement, I'm thinking 4 rack mount type batteries. Cost is the biggest factor

Yes, 2x6 on both sides of the 4x4 posts. The cross bracing is the 4x4s in the corners. The front edge is off the ground for 2 reasons...1 dogs, 2 i will eventually frame the sides and the front edge in to make a shed.

My current setup

I use an 18 unger squeegee/mop combo and a 30 foot pole. To spray them down i use a ryobi portable pressure washer.

Use the same type heat shrink you used on the cables.

You may need to check your local fire safety codes. Most places require a 2-3ft setback on the sides.

Temco is good stuff, Its worth the price... especially if you have lots of emt to run.

If you're getting shocked from touching things like the outside of your breaker box or your solar array then you have an improper ground.
