[@Penguinmemes9]

How do you conduit the pV cable that is part of the panel ? Is it necessary?

[@CountryLivingExperience]

I have never done that. You only need it to come into a combiner box near the panels and then into the conduit the rest of the way to the inverters.

[@billparsons7732]

Is there a reason you didn't pull THWN from the combiner box to your inverter(s)? PV wire costs much more than the same size THWN with 600-volt insulation. I also don't understand why you pulled the wire with installed connectors. Thanks for the video.

[@CountryLivingExperience]

You're welcome. "PV cables usually have an XLPE insulation with excellent resistance to sun and weather, as well as extreme temperatures. Also, the regular DC cables only last between five and eight years with the best maintenance. This is unacceptable for solar panels that are designed to last a very long time. Therefore, the National Electrical Code prohibits using just any cable in your solar panel. The only two options you really have are PV wire and USE-2 cables. PV wire is specifically rated in accordance with UL 4703. THHN wire is used as general building wire and lacks the construction and strength of specialized cables designated as UL 4703 or USE-2. Solar PV photovoltaic cables are used throughout the entire lifespan of the solar panel, which is typically 25 or 30 years, and the manufacturer typically offers you a warranty for this entire time."

[@billparsons7732]

@@CountryLivingExperience Thank you for the detailed explanation; it's appreciated. I was referring to the cable run from the combiner box at the array to the house. Meaning only the cables in the conduit that have no exposure to UV or the elements. Therefore, THWN, since the wire is outside in an underground conduit.

[@CountryLivingExperience]

Ah, I understand. The solar company recommended that everything on the DC side be with PV wire. I have to go with their recommendation and guidance. Additionally, the other big solar channels David Poz and Will Prowse use the PV wire all the way to the inverters (though theirs usually does not look like it is in conduit). Your call my friend.

[@mentalarson]

You mentioned you're going from the panels into a PV combiner box, correct? I'm setting up an 8S2P array (395W 49VOCx8=392V), and Signature Solar told me I can use Y connectors from the 2P strings right to the DC disconnect then into the inverter. I'm still a little fuzzy on all the fine points of solar components, but I'm curious why that additional component is necessary at the array.

[@CountryLivingExperience]

That is what they gave me too and that is what I currently connected. I will add the combiner box later but only for adding spds for lighting and not for combining anything.

[@stevenlane729]

As I understand it, the combiner box will have fuses and diodes to protect individual strings (from over and backward current), a y connector wont provide this safety feature.

[@fisherus]

How are you ground bonding everything from your PV array to your inverter? I didn't see you run a ground wire between them through the conduit.

I have been trying to research if I needed to run an additional ground from the array and can not find a clear answer...some do and some do not.. Thanks

[@CountryLivingExperience]

@@KK7BGA I researched for 2 years and consulted with Signature Solar for a few months before I started building my system. I never once ran across anyone who ran a ground wire from their panels to the inverter. It was not suggested by Sig Solar. There is no provision for it in the equipment and it is not built that way. I don't know where you saw it. What is done, is grounding your panels if they are installed on your roof or on a mounting system that is wood. The panels are connected to one another with grounding wire and then grounded near the panels. If on the roof, the grounding wire is brought down and connected into your main panel along with every other ground. It is not directed toward the inverters.

[@gardenwonders3308]

It looks like you didn't list the red black pv wire from Sig Solar. You had to cut off your mc4s to attach to your dc cut off. Probably would have pulled easier w/o them. Did you not put in an AC cut off?

[@gardenwonders3308]

The solar PV wire is 10 ga. If I run these to a combiner box, would I then run a thicker wire from the box to the house? It looks like you were running PV wire through the conduit. 10 ga? Now for my dumb question. I am still confused about the use of a connector box for strings. OK, 2 strings of 5 x 40 V= 200 V and around 10 Amps. If I join these two strings into one, do I get 200 V at 20 Amps, or 400 V at 10 Amps? I think the use of strings is supposed to keep the voltage lower.

[@CountryLivingExperience]

I had plenty of room to pull with the connectors and it was easy. I needed to keep them to add on to the end as my run was over the 100ft lengths I purchased (122ft). I have a PV(DC) disconnect near my inverters.

Dude, why such a large diameter conduit and why fish with connectors attached? Use a smaller diameter conduit and fish without connectors. Can’t understand why you would do it this way unless you bought wire lengths with connectors because you weren’t comfortable installing the connectors yourself

[@CountryLivingExperience]

First of all, it is practical to use a diameter of conduit that is larger than needed in the event you need to run more wire in the future. I will be adding to the system so, I will need the extra room instead of running new conduit. It is also obviously easier to pull through larger conduit. I am completely comfortable with adding on connectors but I needed them on the end because I needed to add extensions on the end to complete the runs.

[@waynehartlerode8936]

Oh man... wasteful to run that expensive uv resistant wire through conduit! Pointless. It will never see the sun or extreme temperatures. Seems like a good idea to switch over to some thhn wire once in the conduit. Lot easier to pull also! I'm pretty sure NEC is good with running 10 awg thhn in conduit even if its buried.

[@CountryLivingExperience]

It cost me less than THHN at the time. Always run underground wire through conduit.

[@Maurice1151]

Hey mate, why did you run your cables with the mc4 connectors connected?

[@mentalarson]

It looks like you were able to feed 4 MC4 connectors through a 2" conduit. Do you think I can get 8 MC4 (4 sets) through a 3" with 90's at both ends using the same staggard method? I'll probably tape up the whole snake and try to feed it through the conduit before I bury it, but I'm heading off to buy the conduit now, and I'm hoping 3" will work. It's nasty expensive and 4" is even worse...or would it make more sense to lop the ends off my 100' MC4s and feed 8 wires through a 2" conduit? I was planning to cut 7' MC4s to run from the 100'ers to the DC disconnect then from the disconnect to the inverters to avoid cutting the 100s.

[@CountryLivingExperience]

Yep. That is actually a 1.5" conduit. I did put a little bit of lubricant in the conduit but they went through with no issue. I think 8 would go through a 3" easily.

[@Wrensspeedshop]

Yes you can. That’s more than large enough to run 8 runs through. I would honestly run your cables through 2”, and if by chance you have about a foot or two of cable that you can spare, you can always go through and cut you 8 pieces and tape them together and go up to the hardware store, Lowe’s, Home Depot, etc. and figure out what size pipe it will fit in. If you try to put it in 1.5” and it just barely fits then you definitely want 2” inch because you’re going to have to account for any bends or twists & turns that you may run into.

So...2:19...you condoit?

[@zuzax1656]

You are a great teacher, not only because you admit when you make a mistake, but explain what you did wrong and what to do to correct it for your students (us, your fans). Me, being a wannabe engineer, saw how you had the wire coils on the PVC roller and immediately thought, "this will not end well." Notably, because the roller itself wasn't centered to the riser (the coils will tend to gravitate toward the pulling force), and there was no separation between them (a piece of heavy cardboard, or scrap plywood, a little larger than the coils will do), which will lead to them getting tangled, as you found out. The only other question I have is whether you wanted the MC4 connectors to remain on the wires as you fed them through the conduit for some reason? It seems that it would have been easier to feed the cables through if you had cut them off (leaving enough wire to splice later), if you didn't need them at the switch. I presume it was just an oversight in the excitement of getting a major step done, which, to be honest, I'd have made myself. Oh well, hindsight is 20/20. I'm really looking forward to the next episode. P.S., I was wondering if you are planning to have a licensed electrician check everything over prior to 'throwing the switch'? My belief is that it is always a good idea to have a wisened set of eyes check my work, especially if it is out if my wheelhouse. Besides, you could make a new friend that may lend their expertise for a plug on your channel. 😉

[@CountryLivingExperience]

Thank you, I appreciate it. I am certainly no engineer either. I try to learn from my mistakes and am not afraid to show them. I did want the mc4 connectors to remain on those first runs of wire because I knew the conduit was large enough and it was way easier to connect extra lengths to the ends than splicing them. I actually had a friend of mine, who is a licensed electrician, connect the breakers at the main panel for me. While he was here he obviously looked at the whole system. He doesn't know anything about solar but said I had all of the other connections correct in theory.
