[@kameljoe21]

If I recall that is 50k just in the eg4 batteries and I can not be sure yet I am sure those sol arks are 8k each. This is likely a 150k dollar system. Yet if you are 100% on electric for heat and cooling and lets just assume they have a very high end electric bill of 6k per year which gives a pay back of about 25 years. Sell excess energy and you could see a payback in 12.5 years maybe. The real kicker is that these people likey have more than enough battery power that will extend the life of the cycles for 50 plus years.They also could be running crypto miners which cost them nothing. With all of that extra energy could could run miners all the time and cost you nothing. Even if the crypto market is down lot of miners shut down operations because they can not make a profit yet because its solar you can keep mining and just moves your pay out time much longer yet if the price goes up to pay it off or upgrade you can do that. Just more free money.

@@kameljoe21 their power bill could be even larger than that, they probably power lots of power tools too for a garage/shop, well pump if they use well water. Where I live, if I use $300~ of electric, my power company literally charges me ANOTHER $300 in FEES! I can use 2500 kwh of electric in a month, and the power bill will be $550-600, with literally HALF of it being FEES! They should get a decent ROI, but the peace of mind that they can survive grid collapses, SHTF scenarios, and stuff like that, is also great. Plus, all of their equipment still holds value, even if it does depreciate some, it still increases the property value, so if calculating that, then their ROI is even better. So if they spend $150k on a system, and after depreciation say it's still worth $100k, then they only need to get a return on investment of closer to $50k, while still having all of the other fantastic perks (non-grid reliant, SHTF situations, self sustain, pleasure of owning such system and being their own utility company).

Just shamwow, a massive Battery bank of 153 Kw/h that I dream of. As an IT Linux Node tech don't be mad but I would be just a tad skepticial on stacking those bad boys on top of each other with no or little airflow doors. Stacking the rack-mounted units on top of each other in a server rack unit can potentially lead to heat buildup, especially if the batteries are tightly packed. To avoid excessive heat accumulation, it's advisable to allow for adequate airflow and spacing between the battery units. This can be achieved by limiting the number of units stacked vertically and ensuring proper ventilation. Usually server rooms feed the cold air at the bottom front and exhaust it away at the top rear. Hell your getting free energy may as well do this. Definitely awesome videos keep it up.

I have 1/4 the panels and 1/3rd the battery capacity. Now this is a system. I build my own battery banks to save money. I spend $10,000 well just under but close enough for $60kw 53.5kw usable. that gives me 2.5-3.5 days with no input. Usually I can go 5-7 days in winter. I will add another 9 kw of solar and another inverter since I use Growatt all in one 5000US version ( I will max out each inverter at 6kw PV). Might change to EG4 6500watt inverters. Right now my whole system was under $15,000 since I bought used panels and built my own ground mount. I have seen 90 MPH winds and no panels loss yet.

I also wonder if most fire departments wouldn't worry about having so much lithium inside a building (code here required it to be outside and 10+ft from the house etc). Anyway you have a cool setup but it's a lot of wiring and space - does look fun.

[@kameljoe21]

I have seen those mega packs. They do look quite cool. Yet most people do not use that much energy and a system like yours has to be on the 100k range. Though you did not state if you were off grid with solar or this was a back up system.

[@wcoekaer]

@@kameljoe21 yeah just over $100k (all battery/inverter fully equiped/wiring etc). I'm disconnected from PGE so off-grid electrically. 230kwh is a bit on the high side but with the bad storms during winter months, having a normal size house, you need a lot of battery storage, I think people tend to lowball the requirements and then get anxious. I've dropped down to about 40% capacity for a few days, usually drop down to 50% for the dec/jan months a couple of times. And that's in California where we do get sun during winter months.

[@kameljoe21]

@@wcoekaer That is pretty good. I did a basic calculation and found that if you spent 100 even and at 22 cents and used an average of 100kwh per day it would take you 13 years to pay for itself. My question is do you have an EV because if you do then that is where all that extra energy is going which could be a really good thing. I think we pay right now 16 cents per kwh and we use quite a bit less energy that you do. I would like to go 100% electric when I build a new house in a couple of years which is where I want to put in some solar. Nothing like what you have. I am considering using EG4 branded mini splits which can run directly off solar, grid tied or a combo of both. In the end the pay back time should be far less overall. The only problem with going full solar is the cost of adding batteries. I intend to buy used panels if I can find a supplier that can also supply ground racking, I would ideally like to install 50kwh of solar installed for no more than 40 cents a watt. Even if I have to have help to install it myself. I would like to find a battery less invert that can be stacked yet this poses a problem because I have only found one unit so far that has that option and I am not even sure if they still sell that model anymore. If I can go battery less with grid tied then I wont worry about the grid going off as I can stil have power during the day. With a stacked unit I can over size the units by one. and the 40k solar will be more than enough to power 4 to 5 stacked inverters and the other 10k is devoted to the heating and cooling system, which can accept a max of 3kwh of solar.

[@wcoekaer]

@@kameljoe21 if I had the ability to connect to PGE it would average at like 40c if you have a decent amount of consumption. I do have an EV (2 on regular basis when friend visits) charging. pay for itself in my case was a different choice - I don't have power at the street, it's 700ft away, so my cost to have utility power would be 700ft of underground cable (100% my cost). I'm better off with my setup right now :) But one thing I have learned is that it's very easy to undersize and underestimate solar + battery needs for normal living arrangements. especially if you're disconnected and have no backup generator. December/January are rough months. Size for those. sure, I have 4x more power during 50%+ of the year than I need but that's because I need it those 2 months.

[@davidb.5544]

If you look at installation manual for these larger panels most will mention that 2 rails (4 bolts per panel) is the MINIMUM. If you are in a high wind area or installing even larger panels you can use up to 4 rails per panels (8 bolts per panel). Vikram 540W panels require 4 rails just to get the "normal" 5400Pa load rating. So they should have installed 4 rails per row instead of 2 if wind was a concern which would have made big difference.

[@kameljoe21]

The only thing I hate about all in one inverters and system like this is they have no option for battery less. What happens when or if something goes wrong with that battery bank and you had to go days or week with out some form of energy. Let say you have no grid and no generator. There is one mpp solar all in on that I know of that is batteryless yet you can not stack the unit. If I could just buy the inverter and solar and stack them along with being grid connected then I would opt to get started right away yet because they do not offer anything like that then there is not point. No I do not want grid tied stuff. I want an off grid system that just has no batteries or the option to add them later. EG4 also makes or brands a mini split with heat pump that can be run directly off solar. In this case I would I am opting to have these installed. I priced them out and to get started right now today I would need to spend on the low end 6k with brand new panels, Cheaper if I bought used panels. This would be enough to off set half of my heating and cooling cost and pay back would be 3 years. Though I am hoping to have everything done and ready to build in 2 years.

Seems excessive but I designed my system to have 3 days of power based on average kWh per month over a year. The. I added 30%. Even for low usage consumers the system will be bigger than ya think.

I didn't see how big the house is, but even if you've got decent insulation, triple pane windows etc... if the house is big enough, say for a 5 bedroom two story with a basement in the NE USA (~3000 sq. ft/floor) or south-central Canada, based on what I've seen from people's usage, I wouldn't be surprised to see 2-2.5 MWh/month in summer with AC and 4-6 MWh/month in the three coldest winter months if heating with an air source heat pump system. Say 38-43 MWh/year depending on the weather. Peak single day load in winter of 300+ kWh/day for the odd -10 °F (-23 °C) cold snap. And that's before EVs.

[@mx96288]

could he make it over the winter with that without generator support?

[@johnchartrand5910]

Somebody is saving huge money moving forward

[@jamesmancine8350]

That is an amazing setup.

[@rogie88salazar82]

Wow very nice. Only if money is not a problem 😢

[@6n518]

$1750 for this battery from practical preppers. $1299 for same exact battery from Signature Solar. Which would you choose?

[@eastmanresearch3143]

does the post pounder work through cobble? How much ground without rock is needed? Thanks. That setup is so impressive.

[@robertkehlerjr.8258]

Where do you get the solar panel brackets … I got the same ground mount steel from an auction only thing I did not get was the panel mount brackets

[@robertkehlerjr.8258]

I am building a 32kw ground mount with (120) 280 watt Panasonics panels and need the brackets, can you send me the link for the bracket mounts please.

[@robertkehlerjr.8258]

I’m using the EG4 6500ex all in ones for my home rig, have used one testing its out before doing the full install and they are pretty reliable, got all of my batteries from the auction also they are the generac 50ah lipo batteries, I’m pulling out the proprietary bms’s so I can use with my system … 2100 ah for $2300 including adding the new 30 amp bms’s. I’m pretty stoked for what I have invested into this monster system. $30 for each panel $3600 $400 for all of the steel and $5300 for all of the inverters $11,600 for the whole rig plus the wire costs not a bad investment.

[@NeverTakeNoCut-offs]

What do you do when those batteries start to fail and they are no longer made? I suppose they don't need to communicate.

[@jetfu400]

Ive done some computation. If that amount of battery is D. I. Y built. It will only cost around 34,000 dollars... How much did it cost him in all that eg4???

[@opietaylor9308]

I hope you know that SolArk will not standby the warranty if you are using EG4 batteries. Going through it right now.

[@colbyboles1124]

Do tell please...

[@joeeperjesi8591]

I am curious as to the quality of the SolArk inverters? How do the Sol-Ark compare to Enphase both in quality and cost?

[@davefroman4700]

I don't know but I think Curtis Stone has the biggest EG4 bank in North America today. 48 units.

[@tujuprojects]

10:03 build quality of those boxes looks like developing countries compared to european ones. :)

[@lemonagaming]

This is my dream 🤩 system

[@martingargas3217]

How do you EMP harden the system? Where are you located?

[@DanBurgaud]

What kind of Panel Clamps did you use? ie, these are bolted from the underside; the ones I use are bolted from the top which obviously is NOT practical for installs like yours.

[@bradlewis55]

When paralleling the Sol-Arks can you take one of the four down for maintenance without bringing down the whole stack? My main complaint with outback skybox hybrid inverters is that when you take one down for maintenance, the whole stack goes down until you bring all 4 back online...

[@USA-GreedyMenOfNoIntegrity]

You just turn them off, move Com cables as needed, change settings for whatever number of SolArks are running…get the bad one repaired and change everything back. That’s why I’m installed a third 12k soon. Redundancy.

[@kentsmith6063]

I wish I had a backup power system like that

[@kimryansolijon5644]

insane setup!

[@royamberg9177]

Lots of energy there

[@HenkBronkhorst-c8c]

but respect mate it looks good the weight?

[@TheJensss]

Any pricing information available for the panels? I live in Norway and all the local resellers have huge markups on the panels they sell, so im thinking of just importing a 20 feet container from China with Q cell panels.

[@kameljoe21]

In the us the price per watt is around 50cents per watt USD and when included shipping it is up around 75 cents. If you have low or no import tax in Norway then you should have no problem ordering an entire shipping container for really cheap. The only problem would be docking, shipping, custom fees and a whole lot of other things. You need to make sure you know everything before you buy because in the end something dirt cheap may end up costing you double because you did not know about port fees. I have looked at several machines that were 1500 USD and that is the cost to ship them to the port which is a day's drive and 1400 miles away. To get that same machine shipped and pay port fees would make it not worth the cost and pay a few thousand dollars more and pretty much buy the same machine with less options for someone who makes them in the US and have it delivered in a week instead of 2 months. Now if I were to buy a whole container full of them it would be cheaper yet I would have to sell those machines in a market where no one wants one.

[@TheJensss]

@@kameljoe21 Thank you for a great answer! Yes there is a lot to think about and regular consumer VAT in Norway is 25%. But if I buy as a farmer and the business that the farm is registered on I would not need to pay VAT, since businesses does not pay VAT. I am also lucky so a the largest shipping port in Norway is only 1 and a half hour drive from my farm, so getting it trucked to my farm should be a reasonable cost. The thing I’m most worried about is getting real branded panels with high quality, and not fake or B products that has much lower performance and quality. So getting figuring who in China to buy from, and what brand of panels is fairly challenging.

[@kameljoe21]

@@TheJensss My best guess would be to go local and buy a panel from them. Then use that information to back track to a supplier else where. Since you are a farm and you will likely want to get in with other farms which can help cut the cost over all. That is about all I know. The only thing you can do is have sample sent. Video chat with suppliers, phone, photos, and so on. Its likely that if you find the right person you could get a lot of panels at very little cost to you. For example if the unit cost you 100 units and you do all the work and you charge 25 of your farmers 104 per unit and local they sell for 150 a unit. You can get all of your panels for free and they will have gotten a super good deal. That is just an example and I have seen people work deals like that before.

[@TheJensss]

@@kameljoe21 Awesome! Yes this would be a subject to research thoroughly before buying, since price differences is huge and the quality difference even greater. I'm planning to use around 200-300 kW of solar myself, where the panels would be oriented in different directions to capture sunlight the whole day and avoid a huge production spike in the middle of the day with power im not able to use. The large array size is to accommodate the low production and huge demand for power in the winter, and the production restriction with different orientations on the panels would be to accommodate the "power production tax"that applies for power producers that have over 100 kW backfeeding to the grid at any given time. So that is not an option since the taxes are extremely high.
