He's Baaack! Always good seeing another video, Will! That said, quick suggestion for a future video series... how about going back to your roots some and doing a deep dive series on what your ideal "budget" and "mid-grade" systems of choice would be for a class C Motorhome, that could easily handle weeks/months of off-grid camping and not take up too much space(!?)
The cost on this stuff is nuts. BUT....of youbhave a way to pay for it even a loan...and if you size it out to cover your utilities...set the term up to current utility payments and folks would be surprised how fast the return actually is.
@@phillmckrakin2518 I'm in my 40s....I can ALMOST relate. I look at it like this....I am going to be paying someone something every month for heating, cooling and electricity, might as well be paying the mortgage company and have something to show for it. Besides....doesnt have to be a 20 year line of credit. Make it 10 or 15. We have been programmed wrong. We don't bat an eye buying a vehicle for 40 or 50 grand only to be worn out and worth 20% if we are lucky of what we paid for it by the end of the term. Buying/building a power plant for your property appreciates over time in two ways. Both in rising energy costs and in you property value.

Congrats on your life choices and your vision of how life should be. Keep doin you man cuz it's contagious. :)
Love that you made this. I so could have used something this simple when I was pulling my hair out. Aside from the lack of documentation on the capacitors, Signature Solar has become so popular thanks to your forum and DIYers' recommendations, that I don't know that their staffing is up to the influx of orders. They absolutely did their best to help us make it right after I put my foot down on being overlooked for multiple shipments. We're happy overall.
Will, the reason why they are not made in the USA simply comes down to economics. The average salary in China is about $16,000 USD per year. Compared to about $56,000 in the U.S. Also, the cost of an employee in the U.S. is quite high (in addition to the salary paid - ask any business owner). We Americans, me included, demand high salaries but also demand paying the lowest price we can for our goods. If the manufacturing of the item requires humans to touch it, it will be far more expensive from countries like the U.S., Canada, Germany, etc... It could be argued that you are getting a better product, "you get what you pay for", but most people don't care about that. For most, not all, but most, it comes down to price. There is a lot of information about this subject out there if you want to be put to sleep. You provide a great service to this community. Keep it up.
Everyone focuses the hourly wage, but not the taxes, grift,regulations, and as you mentioned, the cost of renting the tax slave from the government. The cost of shipping one of those batteries to the US is about $500 all included, so why aren't we making them here? Because the Chinese are pro business and the USA is not. Sad but true...
Perhaps we can fix that by instead of paying our taxes we pool the money together within our communities with people we trust, make everyone there a manager, buy gold and silver make paper money out of that backed by those precious metals then fund building these manufacturers to then produce this batteries at a set price. Idk just a thought
I wish they'd just drop the tariff and we could buy these without all the additional tax. The government dumps money into green initiatives but won't give us normal citizens access to cheap energy storage subsidized by China. What are they really trying to accomplish by giving us a tax credit then adding a bunch of tax to import the hardware. It'd be awesome to buy one of these for under $1000 bucks and take some energy off the grid.
People used to look for the Gold Seal of Approval we look for the Will Prowse seal of approval. Thanks man your videos are always so informative. Even when your "it's so easy" makes me say "for you". Thanks🙂
Facts. I don't a single thing for my system without checkung out Will's review first. Even something I already have, I still look for an update from Will. (See his weize battery update as a reason why...they started to make em crappier over time)
Totally agree! These need to be manufactured in North America so that we're not as reliant on overseas; you'd think shipping costs alone would make up the difference. But I'm sure it still comes down to labour costs. Thanks for this quick overview!
I just stared using the Growatt 48v 5kwh Axe battery through Signature Solar. They are the easiest battery I have ever used. They plug into each other in stacks of up to 10 high. So far so good.
Yeah, Current Connected has OUTSTANDING support. I'm a DIYer in a dinky mountain town so support had a lot to do with purchasing 3 48s. Other contenders fell way short in pre-sale questions and it cost them the sale.
Thank you so much for continuing to make these videos I can’t tell you how useful this has been I’m about to upgrade my cabin to a house and will be using a lot of what I’ve learned here again thank you so much😁
This might sound strange, but I think a lot of people do not understand what a "Server Rack Battery" is and so they do not bother to click these type of very useful videos. They need to understand it is just a typical shelf (i.e. rack) that holds several batteries connected in series or parallel to provide electrical storage power. A very simple thing. Once they understand, you will get many more hits. Bty, I love my Dewalt Rack!!!
I use a separate 20A switch with a 10 ohm 50 Watt wire-wound precharge series resistor in parallel with the main battery switch. This makes powering up the converter from batteries much easier.
Thank you Will for all of your wonderful videos! Together, they represent a priceless knowledge base on this subject and your upbeat demeanor, even in the face of not the greatest discovery, is always welcome and sometimes entertaining! You and another RU-vid guy (who builds cool stuff) present some comical stories of dealing with battery sources in countries very different from our own. I'll simply say that facts don't care about feelings and some suppliers just can't appreciate that. I am writing this as I sit in my tiny RV where I live completely off grid, in the middle of the city and hear my propane fueled generator humming away in the background. After surviving on a pair of huge 12 volt SLA RV batteries wired in parallel, a 30 y/o 600/1200 watt Chinese inverter, and my Westinghouse Wgen3600DF generator (with R/C!) for a little over a year, I purchased a PowMR brand "Solar Inverter Charger" (POW-LVM3.0K-24V) and one Chins 24 volt/100Ah lithium battery and am awaiting my own decision on solar panels. I'm considering higher output (200 watt
After my RV Solar system 20 years ago, I am building a house, and the solar system is part of it. Thanks for the video on the battery server. As a Chinese American, I can explain why China made these. 1. Chinese salaries are 1/4 of American salaries. 2. Raw battery material has been acquired by China worldwide for 20 years non-stop; 3. Strong government encouragement to local province to build the next new industry. 4. Green power lowers smog in large cities. 5. China wants to be independent of oil from the Middle East, which America controls. 5. Battery is a relatively low-tech industry, unlike Semiconductor AI chips. 6. Low regulation at all levels. 7. 1.4 billion people produce highly competitive engineering skills and companies. 8. Chinese culture generally likes cheap and usually competes in price (good value). 9. The Chinese government is trying to bring another 400 million people from poor to middle class, so there is a lot of cheap labor. 10. Central planning produces a long-term industrial plan, especially for infrastructure-build like the Silk Road. Like other Asians, Japan, South Korea, Singapore, and Taiwan follow Confucian philosophy: working hard and delaying gratification.
You're the best Will! Love your helpful videos. You helped me realize we are going into a golden age of offgrid living and responsible sustainable independent living.
Will, you are awesome, been following you since your van stuff. Really proud of how far you have gone and cant wait to see where you go. Such a good looking guy with knowledge beyond most 2x your age. Continue your good work, always happy to logging into youtube and seeing a new video by you.
He's BAAAACK! I've been checking on the daily for a new video, glad to see one pop up. Perfect timing since I got a cabin recently and am making a plan to use all server rack batteries for the cabin and then the garage I'll be building on the property.
@@duunoit I'm already subscribed with notifications, but I stopped paying attention to those alerts at the top right since it gets flooded with too many other notifications
I can't speak highly enough of Current Connected and the SOK batteries. Dexter from Current Connected went out of his way and was helping me and others on the forums troubleshoot some communications issues between the SOK batteries and LV6548 inverters. It ended up having nothing to do with the batteries and was caused by buggy firmware on the inverter. Dexter is awesome and so is Current Connected. I have a smaller system so the SOK batteries made sense for me, but I'd still purchase them for a bigger system. The display is nice for troubleshooting any issues you may be having. It doesn't get used often but is nice to have when you need it.
I've got a small hot spring resort near me that is completely off grid, it is an absolute mess tho lol They have all old 18+ year old inverters and chargers, solar panels are a mess of mixed and matched old and new and broken panels, the batteries are giant 10+ year old lead acids that have been overcharged and boiled countless times from the generator overcharging them because of com errors in their system. Its an absolute mess. The place was bought not to long ago and I want to see about talking them into getting new server rack LiFePO4 batteries and just fix the system up in general. No one there knows how big the system is, but I believe it should be somewhere around 300kw for it to work well at least.
I would argue that Trophy Battery not having branding is HUGE selling point over other brands. It's incredibly clean, and those looking to go off grid entirely are looking to get away from corporate branding. They definitely need to work on their advertising, but not by changing the way their batteries look. They are perfect as-is.
JUST WOW! What a terrific stack you have going on! I appreciate all your videos... I seriously started learning enough to give me the confidence to buy my first small set up... I am a slow learner... your teaching method is awesome! THANK YOU!!!
So a couple of questions. 1. I see that on Amazon, they sell complete systems. Perhaps you could give your thoughts on some of these at some point? 2. Where do you see solar power in 10 years?
Wow, that's a lot of rack batteries! Interesting to hear of pre-charge problems with the EG4 - mine worked perfectly with one LV6548 (haven't tried it with two).
Yeah I've actually connected it without precharge, had a huge spark and it worked great. I've actually done it multiple times off camera 😂 but some people are having a lot of issues with it on the forum sadly.
@@WillProwse Maybe with the higher volume, it has uncovered issues more quickly. Watching AmbitionStrikes video with CurrentConnected, they mentioned that the SOK battery pre-charge system was not enough to handle charging a pair of Victron Quatro. They manually charged with a resistor before making the connection.
And now there is a 7.68KW 150v server rack battery on Amazon, and they have the same specs on a wall hanger battery for the same price. Before they sold out, they were willing to ship them up here to Alaska for free. I already have some Chins, but if I was building a new system, I would not mind getting them.
Thank you will, right before I am ready to buy 30kwh of battery. I'm somewhat disappointed with the golf cart. Grab that B grade pack you had before and make a real battery that fits. Could be a great time to do BMS round up again now that so many use Bluetooth and have apps that support them. Thank you for all your time and energy regarding this.
This might be a crazy idea, but what if you used these rack mounted batteries in an electric vehicle? Let's say hypothetically that you wanted 100kWh of storage with these batteries. To do that you'd need 20 of the EG4's, SOK's, Jakiper batteries. Those would also weigh quite a bit more than if you had used the 300Ah Trophy batteries. You'd also only need 7 of them to hit 100kWh of storage in an EV. EG4: 20 x 109 lbs = 2180 lbs SOK: 20 x 99.2 lbs = 1984 lbs Trophy 300Ah: 7 x 242 lbs = 1591 lbs From 2180 lbs for twenty 100Ah vs 1591 lbs for seven 300Ah, that's nearly 589 lbs! Based on the available numbers, the Trophy batteries would be the best setup for an EV. And since they're self-heating, you wouldn't need to worry about charging issues. Cooling might be a problem, but fans and heat exchange is already an established thing with all vehicles. The biggest advantage for a rack mounted system in an EV is that you could hotswap the batteries in the field. There is already a company out of Australia playing with this idea for Semi trucks but if you could drive 100kWh of distance and swap out your drained the batteries for fresh batteries, you'd be capable of driving much longer distances. Basically, envision some sort of sci-fi gas station of the future. You drop off your dead cells to be recharged with cheap renewable solar/wind/hydro energy, and you can instantly grab fresh cells to continue driving immediately. Also, why aren't there EV's with a range extending trailers? Hauling dead weight kills EV performance. But what if it wasn't dead weight? What if that trailer had 100kWh of extra storage on-board? And what if that trailer was also partially self-propelled? Most vehicles can tow 2000lbs to 1600 lbs on a trailer. An EV trailer that turned your 4x4 into a 6x6 would be insane. And not just by decreasing rolling resistance by eliminating dead weight either. That's without factoring in regenerative braking while driving downhill.
Hi Will. I love watching your videos. Hey, my wife and I are in our 60's and I'm really set on getting wind/solar power. I've watched about 1/3 of your videos but haven't yet found one that answers my simple questions. Maybe you could make a video. The questions: Where does a person start ? There's so many parts and different kinds of panels and all the rest that make up a system. What is the cheapest way to get started (we're on fixed retirement incomes)? What do we purchase to get started and from whom ? It should really be a system we can expand on as we go without having to purchase things like converters over and over again. Thanks Will !
i would call signature solar in Texas and let them design you a full system.. They have great customer service.I have bought a lot from them. Hope this helps
Hi Will, thanks again for sharing your extensive knowledge. I have watched several of your videos and I always end up taking notes because you cover a great deal of information, usable information that is critical to understanding everything one needs to know regarding off grid solar power. I can’t tell you how much I admire and respect your work. Tim Muir
Thanks for this look at these batteries. The pros and cons are really good to hear. The little rant about the lack of USA manufacturing is SPOT on. We coule be making them here except we have too much corporate greed and far to many C-suite people who have to keep all the money.
My 36v Golf Cart is working great with raw cells (LF280K) and a DALY BMS (250A Smart). Takes work to make the battery bay ready to receive the pack, and some basic water proofing/shedding, but more capacity/less money if you're willing to do some work to build the box. That's a video right there if I've ever heard of one :).
Would also like to see a review of generator transfer switches. Lots of people are doing shady and janky things to use this power in their home. Manual transfer switches are inexpensive and easy to use while being safe.
Great video! I just dipped my toe into solar power with an inexpensive panel and a power station. I had no idea about the rabbit hole I'd fallen into! Never thought I'd be lusting after batteries but here I am LOL!
I was wondering why he didn't mention the pylontech until the explanation right at the end. They are hugely popular in the UK and seem like very good gear, with open protocols and reliable kit.
Just had off grid solar done last year and due to budget constraints I had to settle for 40 kwh lead acid. Will save up to buy the next generation of batteries for when these die. Each of my current battery packs is 1700 lbs had to use an engine hoist to move them into place
interesting on the overcurrent issues with the single battery vs multiple. I just tested a powerqueen, single 12v, 100ah, running through a Roarbatt 2000watt inverter, on a ryobi circular saw, and a Rigid Table saw. Both showed mid 300's inrush, but both worked fine. I was surprised, and the circular saw was running at 1100 watts continuously, which is pretty close to powerqueen's 1200 watt stated limit. It's going to make for a great combo for a mobile solar generator.
I don't know how I missed this video, as always outstanding lesson. Why don't America make it? I think we are only getting further far away from making things thanks to the labor cost, making McDonald's sandwiches is costing more than making technology based goods now days but there's a way around it, make them at prisons & schools for low cost. Thank You for sharing.
With all those batteries piling up, I would think you would be running out of room for new projects. Time to think about possibly a friend build, or maybe supporting some organization downtown, or maybe even consider some type of a give away. I know your fans would really enjoy the latter. Thanks for all you have done in contributing your knowledge and promoting DIY solar builds.
You've been using networking racks, that battery would fit in a full depth rack no problem. Networking Racks are normally cheap due to only be 1 half or 3 quartets the size of a full depth rack. Normally full depth racks are 42" to 54 Deep. My 42u Full depth is a 54". it needs to be this larger to support servers that are 28" in depth Plus a PDU, and Buss bar for grounding that is normal connect to 2 different utilitys and dual in line UPSs And some times even Dual Generators. With water cooling becoming the next thing we may even see 60" deep racks.
That’s a great wrap up video. Really appreciated. Could you make a video that show in details how to make the connections to the home 🏡 main power panel. And all options. Thank you so much for all your instructive and interesting videos
It's funny, everything Will puts together on this channel is very high quality and looks professionally done. Except for the battery set up of that golf cart. That looks like something I'd put together with crap I found in my shop.
Can you do an updated video? Riuxu, Orient Power, etc seem to offer competitive units. (I saw your Riuxu review & it's a tough to choose between those and the EG4 etc.) I have learned a GREAT DEAL from your channel and forums. I'm 62 & after building a beginner (600w) system to power my utility room (internet, some DC lights & ac outlets) here at home. I'm already 'off-grid' as the power company cut my power in March after a huge rate increase caught me off guard. Never again. (When they cut my power - it just meant they moved to the back of the line & solar went to the front.) Thanks for your easy to follow videos!
Great overview, thanks a lot! In South Africa Pylontech is quite revered, you seemed to hint that they might have problems, would be very interested to see a tear down. Also please pimp out that golf cart with some custom battery holders! Would be a cool project. The center of gravity on that thing gives me the heebie jeebies!
I have an idea for you for your golf cart, build a custom battery out of eve cells for it, you can build a battery that fills the battery compartment and then just put a lid over the busbars so there's no issues. Throw a BMS on it and a controller, and bam, good to go lol. Now if you have already done this pardon the ignorance. But I have had this same idea and want to buy a golf cart just for this purpose, and driving around my small village I have no real need for a car unless I'm going shopping or to the nearest city for dinner or something.
This may be a real dumb sounding question, but for marine use it is important to maintain the weight low to achieve a low center of gravity. SOK is well designed for vibration and repair. 🤔 The question: Can the SOK racks be orientated horizontally with the rack handles oriented up to facilitate maintenance and monitoring or would this effect the thermal cooling scheme or mechanical load of the individual rack modules? There is always the option of cramming a bunch of 12V batteries together below decks, but I think the rack system is more secure. Shims could be utilized to compensate for gravity on the rack slides or a custom rack for the modules could be fabricated. I think that bus bars rather than daisy chained cables are a better engineered conservative design. This is SOP both in the Navy and the comercial nuclear field. 😎
Hi Chrome Last year i was using 2 canbat bateries that you got. But this year i switch to one 400ah Ampere Time .Iam loving it!! one batterie instead of 4 and the price of two canbat. Good Custumer service & no bad reviews that i could find. 🙂😎
Hello. In Europe, last three months we work with SYL Battery (a subsidiary of Risen group). Model name GS Energy GBL2.45K3. Pretty good quality, reminds me Pylontech US2000 or Aoboet Uhome-LFP 2400. Also good one is ZETARA 51.2V-100Ah, HIGHSTAR HSD5870, Rosen LFP48V100AH. Tnx for your work, I learned from your videos.
I'd consider the lack of a big brand badge on the Liberty's a premium design choice (like badgeless vehicles). They could make a nicely integrated one for identification though, better than that sticker for sure.
You should build a DIY pack using the EVE batteries that takes up the entire space on the golf cart compartment and eliminate the need for an external box.
Regarding your solar golf cart I think that if you stuck with the Tesla modules and went with the Bpath BMS the concerns you have would be alleviated. It makes his slave out of the BMS board on the modules controls them all the way down to Heating and Cooling as if it were in a Tesla. In the event of any issues like you described the battery is isolated. As an aside this unit is plug and play with Victron via Can Bus and can run up to 26 modules. It should all fit right where your seat batteries are and can handle any level of draw you can generate with a golf cart.
You should note that the fine print of nearly every homeowner's insurance policy will state that the company will not payout in any way if electronics lacking UL listings are found to be the cause of any property damage.
THanks again Will I always learn from you videos. I converted my 36 volt EZGO TXT to Lithium and love it, although there were some issues and it was a pain in the beginning like they sent the first pack with there charge (cheep) and they neglected to set the charge voltage to high 58 volts. So I returned the whole thisng and they resent and it was damaged. they sent a new everything it just took a month or more each time but ultimately it all works. Occasionally it just stops for a few seconds Im pretty sure it is either over current or over temp. but it clears relatively quickly. THe BMS in my pack is not the greatest Im sure there using better ones now. There was a weird problem I got a good charger to replace the Big Battery charger with a Lester Sumitt II but I could not get it to charge all the way, I worked with Lester for about a month, my hope is that they create a profile that works . My wife has a 48Volt Club Car when those batteries die I will probably replace with EG4-WP it should fit I think. If any one has advice please share I will post he same on the forum. What is your relationship with Big Battery now I know you had issues early.
I purchased the hydraulic crimper HWC007000 from your link, I hope you get paid, I had to log into my UK account, Change the country and change the delivery address to my Military address, otherwise the same tool would be $100
You hit my button when you pointed out how dependent this industry and country is upon China. If I were a billionaire and had the means, I would build a battery factory somewhere like, oh I don't know, the Antelope Valley. This place has miles and miles of open space available and the highest concentration of high tech workers in the world. Plant 42 and Edwards AFB are here. Space X and Virgin Galactic and many other aerospace startups are here. Plus there are plenty of unemployed people from which to upon for the work force. Okay, AV Chamber of Commerce, you owe me one.
Hi Will firstly Ive learned much from your videos so many thanks for doing them. I would like to ask some advice. I live in the UK so I realise things maybe a little different to your place. I have solar panels on the rear of my property approximately 3.7kw. It is grid tied at the moment. I would very much like to add some batteries to save some of the energy produced over night. I am unsure whether I need to change my inverter. I am an older person but very keen to learn and understand. thanks for what you do. In my view you are an excellent presenter and educationalist. I have really enjoyed most if not all of your content to this point. You deserve all that you make in my opinion. Regards Colin
Will- first time viewer- VERY IMPRESSED with your knowledge and presentation!!!!! You make it look SO easy!!!!!! hahaha Question: there 'might' be a few of us who want the back up battery option just for emergencies. While reading a Tesla battery site, one comment I noted was, "IF YOU NEVER USE THIS BATTERY, IT WILL LAST FOREVER. THAT would be the goal of my impending storage investment- maximum longevity. I only plan to use it during a long-term power outage. Unsure it would justify a full video presentation, but what would help us reach that goal of maximizing longevity at the cost of not using...trickle charging? Full charging? No charging and/or somehow putting the batteries in a 'hibernation phase'? Warm? Hot? Cool? Cold? Circulation? Thanks to the above video, I am seriously considering the EG4LL. A great service you are providing! A sincere thank you sir!!!!!!! Barry Thompson near Sedona
You need to start manufacturing your own server battery racks made in the US, you are literally the best person to do it because you know them inside out and what makes a good server rack vs. what makes a bad one... get on the case
