Easy Parallel Stacking for Massive Peak Power 

You guys have the cleanest setups ever. The second I hit the lottery You guys are on my list to call!

Nice set up indeed!Incredibly methodical work!

You and your guys do some of the most impressive work I have ever seen. Your knowledge and always bettering your installs are very impressive.

ENGINEER 775 VERY NEAT & ORGANIZED WIRING IN THE RACEWAY. THANKS FOR RAPID SHUTDOWN INSTALLATION.

Awesome, as usual. Stay safe guys. Bless y'all.

Holy hell man! That is an amazing set up! Love the attention to detail. Great project, as always from you.

Very VERY nice and neat system! Thanks for sharing.

Been Doing solar for years .. best way to do it .. well done nice to see good work going out for solar

Excellent Job. Wish someone in India could do such nice clean and Precise Work. Absolutely impressive. Learning million things from You here in India and trying to duplicate by showing to our Staff..

Been waiting for this video, I’m about to stack 2 12k’s myself with 60 panels, maybe more in the future

The inspectors I know won't allow a conduit into an enclosure, without an approved connector - complete with locknut and bushing. Here's how a bulkhead plate would allow proper fittings to be used between the back to back troughs. Say you're using 1-1/4" conduit: hole saw the exterior trough to whatever size would allow for clearance of the 1-1/4" fitting, let's say it's a 2"TS. Continue with the 2"TS hole saw through the interior sheeting, but not through the interior trough (although the pilot bit should penetrate the trough). Then use 1-1/2"TS hole saw through the interior trough. Now build up the conduit and fittings, the right length to go between the troughs, let's say PVC with male adapters on each side, all glued up. Shove the assembly through the hole, into the interior trough. Add lock nut and plastic bushing. On the exterior trough, make a square bulkhead plate that's big enough to cover the 2"TS hole. The plate should have 1/4 clearance holes in each corner. Hole saw the center of the plate to 1-1/2"TS. Deburr and paint the plate electrical gray. Mount the plate, allowing the male adapter to protrude. Add lock nut and bushing. I ususally keep various sizes of 16ga blanks laying around that I had a fab shop laser cut. I had them all painted electrical gray. I do a lot of automation work, where bulkhead plates are frequently used to pass cables with connectors through enclosures. You can use a blank cover, but my fabricated covers look far more presentable.

Great job !!

Interesting railing work there

As I said on scotch I LEARN more from your videos than I ever got from my papa and he always had me on edge to LEARN more and l cant wait for your your next project or helpful hints. Thanks Semper Fi

Love it, quick question? sure ground wires be attached to the metal ground bus? Will wait to see the final installation, Grat job!

Looks great. I have to nudge a little bit. There is $100+ in Myers hubs on the exterior gutter but the gutter it's not rated NEMA 3r?

very nice!

Exellent video. Clean work. Dual Sol-Ark. I want to combine that inverter with KilaVolts HLX 3600 (8 of them).

I love the clean work you guys do, especially with the trough setups, and bypass switches on all installs, looks great. Me personally, I don't really like the idea of having a 'rapid shutdown' right on the outside of the house where any stranger can push it and kill your power to everything. I wonder if you could automate rapid shutdown into a fire detection system that would trip with your fire alarm. I wouldn't want any switches on the outside of the house unless they were secured...

Starting my first DIY system this weekend using Q-Cell. With that said, What mounting base are you using to mount your home run conduit? Awesome work.

why is there a critical load panel when there is 17 kw of solar and 24kw of inverter power??? , these inverters should easily power the entire main panel during a "critical" situation. . . is it some type of code requirement

Some white latex primer and a couple of layers of paint under that stuff before you mount it can save a lot of headache later.

@Engineer 775, love your setup and explanation on this video. But l was wondering why no battery backup storage included?? I also like 3 - way switch box to change up power sources when needed. Saw l need do that for my next home in the near future. Please include a basic wiring diagram too, unless you are worried about property theft. Thank you again for the video detailing how to layout a solar panel installation.

Those 12ks are nice

I did my homework and realize that I was being unreasonable with all my newbie questions. It is an ac combiner box. I downloaded the sol-arc 12 Outdoor type manual and it explained a lot. So I apologize. I am enjoying many of your videos. Keep it up. This morning I saw on the news of the heatwave in California and Oregon and the melting of cables. Have you any feedback from homeowners as to the solar units installed and how they are operating? It would be helpful to do a video on the effect of the heatwave on rooftop solar setups and how to upgrade to existing solar system for future heatwaves.

Can you share the model/brand of the batteries? Nice job guys

Hey there, just wondering what the brand/model of the wiring trough you use. Thanks a lot.

Nice set up. a few questions if you don't mind. First did you do positive or negative grounding on the solar panels? Did the roof racks have provisions for grounding to the panels? I understand some systems allow for the grounding wire to be run with the cables to the disconnect boxes. You used iron pipes to run the cables from the solar arrays, did these pipes and all the iron guttering system had to be grounded also? What size wires were used from the panels to the gutter system? What size panels (voc Isc ) and how many strings ex. 12 in series and then in parallel? Thanks

Amazing system and great craftsmanship!! After reading through the comments, I'm sure there's a bigger plan here? You don't spend that kind of $$$ on that sort of system without a plan, of course plans change.

Hi there. Would it be a possible to do a walk around of the building to know /see what can you run or use in the house with the following system for your next video

That owner sunk some money into that system!

Impressive work as usual 👌! Wish we could get those GE transfer switches in Canada.

I’m confused. Will the service panel for the house be outside of the main house since you said it has not been built yet? How will power get to the finished house? I’m curious because I want to move my service panel and inverters to an out building about 100 feet away from my house. Thanks! Great instal and video!

Great work. I'm about to install a system with two Solark 12 kW inverters. I do have a question regarding the transfer switch. You said it transfers between Solark and Grid. Is that necessary? Would love to talk to you if can spare a moment.

Nice. Why so much space between the components inside the pole barn? Can't the various Panelboard and Sol Arks go closer together?

Yowza. What size and chemistry of battery stack will they be connecting to this monster?

Are the panels ceramic coated? Tough to get on the roof n clean them.

Question: Do needo install rapid shut down on my 48v offgrid system?

On those emergency shut downs, how do you keep the inverter chargers from burning up from the solar panels?

Its that 6"x6" trough? I have some 4x4 ordered, but I'm not sure the Sol Ark will connect to the 4x4 without making bends. What do you think about 4×4 trough?

Great job Scott, as usual. Thanks for the tips on the Terminal Blocks. I'm curious how much did the Tigo's add to the job, time and expense wise if you're ok sharing that?

I hope that as a newbie that I didn't ask too many newbie questions. If there is only one question that you can answer from your busy schedule then can you tell me the type of panel for the grid combiner panel and the use of the grid combiner box?

Can you make that template drawing available to your faithful viewers? I’ve also been directing some of my friends to your website who are planning on doing solar on their custom houses later this year.

Did you have any problem with cross-talk from the different rapid shut down live signals?

Is the generator input up and running on the 12k now? Last one I did I had to use a transfer switch on the grid input to switch between grid and gen. Beautiful install!!

Nice workmanship, you guys are so good. Except, your fall protection while working on the roof! I don’t see any? Everyone wants to go home at the end of the day!

Can one 12k solark use or start a 20kw generator? Thanks

*Rev. Cec I really like that system. Can I be next?

what are those rail? That is a great way to not have a leak attaching only on the ridges.

Hey do you know any converter /inverter that will take an emp other than solark

NEC 2020 690.31B ... don't we need to have a barrier between the PV DC and the Inverter AC output & rest of the conductors in the trough?

Would like to know what PDB he’s using in the video I’m doing a similar setup

I know it was probably mentioned somewhere but how many watts do you have going into each disco??

wow panels do you install

I’m installing 6 strings of 8 (48) 430w q cells, ground mounted. Dual 12K. Can I use two (one for each inverter) 16a 6p IMO’s instead of six like you have here? They are rated 16 a PER POLE.

What brand are those combiner panels?

Howdy from Australia. Thank you for your informative videos. I am considering having a tracking solar array. My thoughts are one axis (east to west geared induction motorised.)( North to south) staged positions relative to elevation depending on time of year. Is their anything on the market like that in the US as I having trouble locating any supplier over here. Thank you. Stay safe Aussie Jeff

What is the name of the distribution utility box? Thanks

Nice overview of the project but a lot of details missing though.

what size wire trunk are you using ?

Very nice looking at putting in a system like this what is a rough total cost panel batteries everything thank you

Why 6 disconnects? 3 per sol-ark. I thought they were for the PV strings and the sol-arks only accept 2 MPPT strings each? What am I missing? Also with the quick disconnect are the other disconnects needed? What is not shown is the wiring diagram it would be nice to see how all the hardware is wired.

Looks great. Do the Solarks start the gen set up, then can you program the Solark to wait "X" amount of time, BEFORE applying a load to a cold diesel engine....AND THEN, once the gen set is no longer needed, it allows the gen set to run and cool down for "X" amount of minutes before shutting down the engine for good? I had a Trace SW5548 power panel back in the 90's that worked like that. I program it to allow the diesel to run for 10 minutes at an idle to warm up, and then it excited the alternator, and when done, it disconnected the alternator and let the engine run for 5 minutes at an idle to cool down. In northern Wisconsin in the winter time, applying a load to a cold engine is just going to really shorten the life of a diesel engine....ANY engine for that matter. I liked that Trace inverter, because it had 3 or 4 auxiliary relays that you could use for anything you wanted and in the menu, set each one up anyway you wanted. One relay I had programmed to kick in a block heater and and a heater under the oil pan, on the diesel and run for 60 minutes to warm up the engine oil and coolant before starting the engine. I don't remember EXACTLY how it worked, but I think it was programmed to kick in the heaters once the battery bank dropped to a certain level and the 60 minute timer began. Another one I think was set to exercise the gen set for one hour every 30 days too, but I can't remember....this was 25 or 26 years ago maybe. I know a friend of mine who had the same set up. He had one programmed to kick in if his batteries were charged and he was still producing solar power, and it ran a well pump and pumped water into his huge holding tank for drinking water for him and his animals, but if the level got below a certain point, it had a float that kick the pump in no matter what was going on with the solar and batteries. Anyway, keep up the great work.

Why use an interior wireway/gutter outside?

If any of your workers don't want to work due to covid-19 I'll gladly take their place! Solar is my hobby and passion!

Scott, question on the Dual Sol-Arks and breaker sizing? Correct Breaker Size for Grid going to sol-arks? 50A or 60 A breaker? On the Critical Loads Panel back feeding from Sol-Arks? 50A or 60A breaker? I believe each solark will allow 63Amp of pass through on grid? So that is why I was thinking of needing a 60 Amp breaker size at the critical loads panel. Thanks for your help!

I looked at the end of the video and counted 51 panels in 3 rows of 17 each. assuming 17.5 kwh it means about 340watts solar panels. This is just a guess. What is the total voc and Isc of each of the sets of solar strings?

Are the 2 inverters out of phase so you can run 240V AC by combining them?

Please tell us how much for parts & labor?

No paint on the wall first?

Hey dude those dc disconnects are redundant and not needed just use the RS switches and your good to go.

Deutsches Institut für Normung, ja goot!

9:44 -- Why fuses and not breakers?

What does a setup like that cost? Holy cow

Did you divide the panel to 6 or 3 parallel groups?

I notice everything exterior is mounted on plywood. Is that the finished exterior or is there going to be siding? That plywood only has about 5 years before it disintegrates.

Scott, I have a question about ground mounts. I just happen to catch this video and this idea popped into my brain space. You and Johnny can give your input on this idea. He and I have been in talks about a ground mounts and my site has less than ideal conditions for typical ground systems (ledge, rock, more rock, some stuff imposing as dirt, earth biscuts and trees lol). I took my mini and dug test holes. Some were very easy to dig about 4 feet down while a couple other spots were just solid rock at 8 inches. Johnny and I talked about ballasted mounts. I don't know how I feel about them. They seem bulky, quite ugly and I see potential for them to be a problem with frost (I'm in NE PA). What about building small solar arrays and installing them on single post mounts, like those used in tracking systems? I feel this would give me more flexibility in placement and size. I know with typical ground mounts that use a single post buried in earth need to be aligned, level square and true to each other. My terrain isn't super flat, has a soft slope, but the overburden is my concern with these. I also want to start small with the system and grow it as it becomes more financially accessible. I have a magnum inverter and charger working off 6 100w panels at the moment. I have no utilities on site as of yet and the power company is giving me a hard time so I'm about to say **** off. I'm just looking for some insight from you guys since you do this for a living. I don't know how often you run into the type of earth I have. Any additional info would be appreciated. Thank you for your time!

IMO HAS 8 POSITION SWITCHES RATED FOR 60 AMPS DC. IVE GOT ONE.

This might be a stupid question but Are there no safety covers for those emergency stops ? Put a red button in front of a ten year old and you're looking for problems LOL !

Heard that tigo breaks a lot, waiting for a customer review from you later, nice job BTW.

I'm so jealous.

👍

With this system. Can you do a whole house 200 amps of power not on roof but on ground ? How much for this sistem

I really love how you install these systems but the over all PV systems is far too complex. I need a plug and play unit that would not need a engineering degree to operate or service if something ever went wrong.

So when you loose power you loose solar, why can’t they develop a automatic switch to disconnect the solar away from grid? I liked the video.

Total price?????

I would say that a rapid shutdown is an overkill.

Sure a lot of proprietary parts for special work I bet an electrician would be stumped on that job

Beautiful setup on a really ugly wall. Why was the wall not finished or protected?

Scott! If you build my micro hydro invention for a video I will fund it ! Contact me!

Nec No more than 6 disconnects per service

Hmmm...where is the siding, they forgot the siding before all the electrical was mounted outside?

Did everyone see Micheal Moore's new movie defending Whaling ship companies, or was it the blubber? Anyway, 775 Rocks! proving energy independence is feasible and growing. And sane investment's grow goodness!!!

Metal ladders?

Did we see the batteries?

JUST HOW MUCH DID T H A T SYSTEM COST ????? . ?? I'LL never live long enough to pay for one like it !!!!!!!!!! BUT I WANT ONE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I'M probably going to build a retirement cabin on a 5A property I own . It'll by NECESSITY , rather than desire , HAVE to be solar . I don't want the solar to cost MORE than the cabin !$!$!$

Why is this not on my house

What is Johnny up to?

I sent in a consultation form a couple of weeks ago? I followed that up with an email but I have heard from you? I do realize you are probably buried with everything going on. Please advise if you got my communication.

No paint on wood ??????
