I have 18 - 450w on one scc and it has been running perfectly with no issues for over a year now.
Very new to solar but started purchasing items, not sure of the final specs of the whole system.

Your 12k had a fit when overpaneled right? The scc is more forgiving it would seem?
It blew the main caps on the board it also had the same panels and number as on the scc.
I had Growatt log in and verify everything was perfect at the time of the failure. I posted the screen from them way back in the thread. They were very adamant about not over-paneling the 12kw, not even a little. The same string was moved to the scc right after the 12kw failure and zero issues.
One thing I’ve wondered is if one overpaneled to say 7400w total (3700 per mppt) and all other parameters were within limits would it tolerate it.
My rationale being that it is seemingly very rare to have an array put out 100% of rated
Honestly, I'm not sure what they would tolerate I would think yours would be fine. But Growatt during the conversations would not answer if there was any tolerance. They just stuck to the same response to not over-panel.

Wish me luck. I am about to hook it all up! One more question, if I may: What DC disconnect did you use for the Growatt 48120's for disconnect between it and the battery?

That last picture of the 4 wires on the busbar, and then the two wires coming off the busbar with each wire connected to a T-class fuse is priceless. I would have never thought to do that!
I had found a bunch of 1000v 2 pole 63 Amp miniature pv breakers, I will try to find my receipt as they were only $11 each. Hope it goes well with the connections.

Nice looking ride.
I've been eyeing those bolt EUVs or a leaf for a while, saw a rural mail carrier in a bolt yesterday and thought they don't look near as bad as the leaf and have better range... Hmmm

I will update the thread as I go over it and get some seat time. I have not had a car with heated and cooled seats before and was excited to have that.
On the short ride home I greatly enjoyed the regen paddle vs the one pedal on the ford. On the down hills it was hitting 54kw on the regen.
We are up in the mountains so we have lots of long steep hills. I was very surprised to see the amount of regen it can hit. With out the use of the paddle it sits between 9 to 10 kw but its braking/regen is barely perceptible.

Regen is simply awesome to slow down.
My Vanabolt, who is heavier than a Bolt can peak at 50-60 kW of regen for 5-10 seconds simply exiting the freeway. ?
Driving uphill and downhill in the mountains is fabulous.

I can’t wait to get an EV or two and charge it on our 150kWh per day of summer excess. I watched a video just now of a Tesla using 700Wh or so per mile going up and gaining back 300Wh or so coming down the same mountain (22 mi). That’s pretty good.

it is truly odd to drive downhill and see your tank fill up

Going down mountain roads with regen is bliss. Beyond getting power back you don't have that coasting faster faster faster, braaaaake.....coast faster faster faster, braaaaake....just modulate pedal and enjoy the regen power gain, nice and smooth... And of course no brake pad wear. I'm over 80,000 miles on my original pads.
