I'm wanting to hook 3 @ 250W panels into a single 700W optimizer, then hook 12 optimizers to the 10K inverter. Is this typical?

Hmmm. We've got a couple old 6" augers laying around somewhere...

So...the rack is grounded by 4 @ 2⅞" drill pipe. And the panels by being attached to rack. 3 strings of panels converge into one junction box attached to one leg of rack; is an additional ground rod for the JB needed here? How about the breaker panel 14' feet away?

Thanks! I'd never considered negative temperatures would effect the panels that way. Looks like series of 12 it is.

Can I use just one 8' ground rod for the entire array? Should all of the 36 panels be grounded to each other? Do I need a separate ground rod for the breaker panel?

We have two systems connected to separate meter loops in our yard. System A is grid-tie only and ties to the house meter. System B is a hybrid and connected to the shop & water well. Both arrays are side by side but their individual inverters are in separate buildings 150' apart. Would i be...

So...? Is the lower end of the voltage range (270-360v, 9-12 panels) better/more efficient than the upper (18 panel) 550v?

Here's the MFG label for panels and inverter

I'm planning a 7Kw array (24 panels @ 250w ea) using a single 40' 2⅞" drill stem for the rack. Has anyone seen a clever way to manage the actual tilt process w/out the use of heavy equipment or gang labor?

So that kind of hillbilly lashup is exactly what I'd like to avoid!

Thanks guys. That's exactly what I needed to know.

My panels are 36v 9 amp...so if I do 2 strings of 15 panels in series that would 540v each. The Growatt 10k inverter has ports for 4 strings. Can each string be 540v? Or is 540v the combined total of all 4?

And I'm not sure what a charge controller is?

The rack itself is (in theory) a single 40' long pipe mounted on sleeved posts and rotates freely. The question for me is the adjustment. 24 panels are not lightweight. One person moving the array from one season to another might benefit from electric or hydraulic assist? A cleverly balanced...

Newbie here, We've built a 36 panel 250W each array with a 10K inverter and 700W DC optimizers. The original plan was to tie 3-panel series (110v) into a parallel string. This, alas, resulted in too gig of amperage. Is there a perfect combination of parallel and series to reach 10Kw while...
