Get an extra few inches incase I can't reach my microinverter. MC4 extensions it is then!

Is that middle junction box swappable with one of the other junction boxes? I see it has some thing that resembles tabs but I don’t wanna go prying at it if they’re not made to be swappable. I’d hate to tear up a brand, new soap, panel and wreck the thing. I read the instruction manual for...

I'm connecting EMT into the plastic junction boxes and my understanding is I need to use grounding bushings because the box is plastic and the EMT needs to be grounded. Problem is I don't have enough neck on the Raintight connector to screw the bond bushing on. If I take off the lock nut then...

This will be AC. It’s the 10awg wire from micro inverters to the 10awg thwn-2. What do you think of these butt connectors. They’re cheap enough and UL listed...

Yea it's for 10awg AC connections. Sounds Like I'm just overthinking it then. I'll stick with wire nuts. Ha, yea I was seeing a good deal of those which got me wondering if I needed to use terminal blocks.

I've got a microinverter setup I'm installing. It has two 30 amp branches. For splicing in j-boxes are terminal blocks on DIN rails the way to go? Any code requirements for the splicing method to keep in mind?

What racking hardware did you use? Iron Ridge says only one grounding lug per subarray is required (and may not be required at all w/ enphase). So I could basically put a ground lug near the j-box and run the #6 from the lug into the j-box. Seems like that would look pretty goofy but would...

Thanks for the detailed info. This was very helpful. I was losing my mind with all the stuff I was reading on GEC which I see is now outdated with microinverter installs.

I've been doing a lot of reading and have realized there are different types of grounding requirements and I may be getting stuff mixed up. Is there a "standard" method for grounding a rooftop array with microinverters (hoymiles HMS-1600-4T) that have a ground wire in the trunk cable ? My...

Another way of putting my question is: What conduit bodies can I use with EMT in wet locations? I think I found one here that meets the requirements. My plan is to use EMT conduit. The boxes, connections, fittings needs to be listed for wet areas Per 314.15 I was having trouble finding...

I’m shopping around for my 3/4” EMT conduit parts and could use some help sorting out what I can and can’t use for conduit bodies. My inspector wants the fittings to be rain tight. It seems like all the threaded conduit bodies are rigid. Can I use those with EMT tubing and RT fittings or are...

This install will be with microinverters and SnapNRack ur-40 rails. Looking at the SnapNrack install manual it appears I'd run #6 copper to connect the rails. then the grounding wire from the microinverters would be the connection to the grounding rod. Am I reading this correctly? If that's...

Correct. It's to ground the array and related racking hardware and then run to the service panel grounding which ultimately runs to the grounding rod.

I have plans with 3 different arrays on 3 separated branches. Grid tied with microinverters. For grounding the racks I'm planning to use #6 bare copper and then transition to thwn-2 in junction boxes into conduit. I'd need to do a few transitions, something like this...

I have 3 circuit branches and solar panels on 4 different roof sections. I'm trying to plan out the details of the junction boxes, conduit runs, and wire transitions and could use some help! Attached are a few images showing what I was initially thinking with the conduit runs. The junction...
