It is however considered when calculating conduit fill, southwire has great online calculators where you enter the type and size of conduit and type and size of all conductors and can effectively and properly size your conduit for your wire.

Agreed, the wire overlap is the least concerning thing in those pictures.

The batteries are designed to bond to the cabinets, thinking you’re just grounding a cabinet is false. The ground extending from the lug in the base of the cabinet that’s connected to the door with the yellow/green wire is both a cabinet ground and a battery ground. Unless you isolate all of...

The mounting ears for the battery to rack connections have a non painted face that makes contact when connected with the mounting screws . This grounds all of the batterys to the rack. Each rack has a ground (equipment grounding lug) at the bottom of the case by the door hinge where the door...

They don’t explicitly list it either. ??‍♂️. Just playing devils advocate…

You’re looking for Auto Generator Start for a portable style generator? Interesting, in for the follow to see how this might work…

That thing will eat up your 14kW of PV and still be hungry, and your batteries don’t stand a chance…

It should also be mentioned that per code only 4AWG size conductors and above are regularly allowed to be recoded different colors for use as L2, neural or grounds as 4 is the size where they start making all the wire black and don’t commonly supply the proper colors. Wire below that size is...

Will the system be grid tied and selling back the excess in the summer? If yes then you’ll build up money or kWH credits to offset use in the winter when the production isn’t ideal-so properly sized a system will net you zero or close to it for the span of the year.

@glandpuck Put them in to satisfy the AHJ and pass the inspections and once you have the paperwork remove them or disconnect them. You’d be better off in the long run in compliance with the NEC for protection than the AHJ adding liability. Simply because something hasn’t been a problem for...

Regarding 8 vs 6 AWG for array grounding purposes. 6 is code if ‘exposed’ but neither are for lightning protection or grounding. They are EGC’s between metal components of the system and all should go back to the main common grounding electrode for the power system/service. Lightning...

Regardless of the amount of the credit, you are loosing production, ROI and value in a system that can be grid tied and earn credit but isn’t. Depending on how much you overproduce in the summer you could, despite the rate, offset some or all of your winter use. You are in essence turning down...

EG4’s chargeverter has selectable amp inputs, you should be able to dial it down to use than gen. It’s 48v too.

If those held a double row of bigger panels I’d bite, but they have a small max size and are only a single row. I want a couple small(4-6) double row mounts for SE and SW angles arrays for early AM and later PM boost. I have about 7kw net to fill the DC max on my 15K

If he did it anything like me, each cabinet has a set of battery cables and the 4 cables (2+, 2-) have space to land on the SA15k battery bus as it has 4 lugs (2+, 2-)

Grid tied-200a main passthru, Sol Ark 15k and large 3.5t -ish central air, 20A deep well pump, etc, etc. no issues here. @Latitude28 are you building off grid or grid tied? This will make all the difference as @dlSOLAR mentions above.

If as is logical to most of us commenting here, that they’re in strings of 10 already, which matches the input to the inverter (3-10strings and 3 inputs wired in the inverter-then at least the installer did something mostly correct. But knowing what you’ve told us thus far about them, that’s a...

Do you want the possibility that your batteries short to their case/rack/structure and that you get that shock when you touch them? If you do not want to be shocked by a short then yes, ground them and their holding/carrying apparatus/structure. Equipment grounding is about being able to...

Wiring in a simple transfer switch is far simpler and easier than a separate second CL panel and a gen interconnect back feed to a main. If you’re already in it deep enough to be changing 200a main wiring to and from a 15k or 18k then putting it inline of the mains with the transfer switch is t...

Very nice indeed, very similar to my Sinclair and my 34-400w Canadian solars. 4 posts, season adjustable. Your ground is flatter than mine-I had to move some dirt to even it up and it’s still not that level. That array will be killer this summer!

Sold in stores is only one option. Online shops sell directly, there is eBay, Amazon, etc that is all available to much of the world. If you cannot (and they’re poor for this application) get wire nuts you should also look for something called ‘Polaris lugs’ or Power distribution blocks. Both...

@SolarRich How many-per tracker, what orientation (portrait or landscape) are these panels mounted in-Please…

You have internet to post here? You can’t use the same to shop for these necessary safety components?

What settings does it have if any? Can you look up its software update log and see if it did a download that coincides with the start of the issue? Perhaps it’s a software glitch in an update.

Yes a simple transfer switch will. A simple transfer switch backs up your whole house and any downstream sub panels from the grid on one of its “ON” positions, the other “ON” position lets you feed grid to the inverter, then to any main and downstream sub panels. It’s exactly how many of...

You can DIY a whole system, including necessary tools, why wouldn’t you be able to itemize components of a diy battery?

Yes, Costco goes back and forth on promotions for the Generac and the Honeywell ones-virtually the same product, sometimes the shell of the Honeywell is a darker grey vs the Generac tan. Kind of depends on what the better deal and esthetic is for the buyer. I doubt there is any significant...

E775 did a video where a customer stacked the 6x racks on top of each other-custom modded them with all thread rod to connect and secure them. Something like 217kW of them Maybe if you review it in detail you can glean some info on how they strung the actual batteries and bus bars together.

You aren’t maxed out. The installer was a maroon and had no idea what he was doing if he “had to get special 1500v wiring” Those are not 1500v panels, they have a system max of 1500v, each panel is only 37.07VoC.
