This is a super quick and easy build. Let me know what you guys think!
links show much higher price than you posted. I do like the build and think it, or something very similar will work great!
@@stephensuter5016 Which item are you seeing a higher price for?
@@stephensuter5016 They all seem to be the samerice when I click on the links - unless you’re looking at CAD or another currency?
@@mondotv4216 Yep , thanks to uncle Biden.
First of all, congratulations on the knowledge of electricity and talent to build your projects. I'm a new subscriber and your videos are very educational and enjoyable.
Regarding this 3000W portable solar power station, can you please give a few examples of how long this power station will last on one charge using different appliances, devices or power tools? For example, if you hook up a refrigerator, how long will it last? A full size TV?
Watching this video during a blackout in PR. These videos actually helped me build a small system after Hurricane Maria.
THIS IS EXCELLENT!
I suspect I may have commented the same previously : Your videos are to the point, void of unnecessary time-wasting talk and just packed with useful information - ALL crunched into a short, concise, easy-to-understand video!
THANK YOU - PLEASE KEEP IT UP!!!
*EDIT* :
Your video has inspired me to build my own mobile powerstation which turned out to be so popular that I have had to build a few for family & friends too!
Wow that's awesome .I think this cart setup is very nice too
Thanks. my thoughts also!
Thank you for your kind words! I completely agree with you, the video is excellent and the information provided is really useful. It's great to hear that it has inspired you to build your own mobile power station. If you're looking for a reliable and versatile power station, I highly recommend checking out the Segway Portable PowerStation Cube Series. It has a massive capacity, powerful output, and fast recharging capabilities. Plus, it's built tough and waterproof, making it perfect for outdoor adventures. Keep up the great work and happy building!
Love where these cart builds are going. It's like the beginning of hotrodding all over again, same with ev swaps into old cars. Every one start learning to weld let's build America into a highly modified craftsmen culture it should be.
One modification I might recommend is mounting the EG4 battery backwards so you have clear circuit breaker access-- breaker on front/top and lug on back/bottom. Also, the Costco 3-in-1 hand truck might make a few things easier-- using self-tapping screws instead of U-bolts as an example, but also easier to use it to haul panels at the same time. It's a little more expensive, but a good value none the less.
FYI the growatt is a BEAST! 2 years in my boat on the ocean. No issues
I'd love to see pics of your setup. I'm hoping to get a 30' Cruisers next year and want power for the A/C and water heater.
Can you provide more info about your setup?
Nice
Thanks for including your costs associated with this build. So many people that do DIY builds, don't.
I am very thankful you are so thorough in your procedures. I wish more people on the tubes did it like you!
This is exactly what I was hoping to find. The technical and physical setup were each explained in a clear manor with the right amount of detail. Liked & Subscribed!
So we’ll done!!! My EG4 is being delivered on Wednesday, I am making my house a hybrid part off grid/part on grid house. I really like this design & great job on the editing. You have earned another subscriber!
I absolutely LOVE this, especially because it’s so mobile! I’m over 65 and just don’t have the strength to move this stuff around and I’ve been wanting to provide myself with a backup emergency power. However, my husband passed last year Im alone and have nobody around to help me do this project. Someone ought to find a way to help those who can afford it but don’t have the help to do it themselves. Calling a ‘Solar company’ wouldn’t do something like this..this is Brilliant!
If you show this video to a electrician most would do this for you or even a mechanic could handle it
Thank you for an easy and wonderful design. I built the portable solar generator, but used 2 EG4-LL batteries to have 10kw. I bought a garden cart (supports 400 lbs) to mount everything on. I used my EGO ZTR mower to pull it around. I also bought 8 (used) 455w panels from SanTan solar for $175 each to recharge it. I estimated the ROI is 5 years for the whole setup. Thanks!
I just discovered your channel with this video, and... THIS is what i like !
Divert the use of an object, to create something useful, better and cheaper than what can be found on the market.
Really creative! Thank you !
This is the best portable power station build I have seen so far. Many of the ready made power stations cost over $800 per kWh. This one comes in at about $521 per kWh and has more than double the capacity. The only thing I would add to this setup would be a copper ground rod with a lead. Then I could push it into the ground before starting up the system. Just an extra safety step.
Would you stick with 48V vs 24V? Im a noob with this sort of thing and get nervous witha nything grater than 24V if you do something dumb..I know, dont do something dumb! lol
@@whoanelly- Personally, I would use the 48 volt. But the 24 volt would work well also. You would also need the 24 volt inverter to make it work.
I like your advice for a ground rod. I am a noob and have watched a number of smarter people build their handtruck systems without talking about earth ground or charging the metal hand cart with 48V. How deep does a ground rod have to go into dirt? Guidelines of 6-8 feet for home grid systems are all I can find.
@@whoanelly- For something movable like this, with a metal cart, 24V would def. be safer IMO.
I have the exact same handcart and love it. Buying the stuff you need for solar is rather expensive, but the ability to generate electricity for free whenever the sun shines regardless of the grid is totally worth it.
I agree that's why I'm doing a system. I'm not doing a portable like this but I thought about it actually and I may do it someday. One of the commenters said he built one for himself that it was so popular now he's building some for all of his family members .I would imagine you could build 1 somebody might buy it
This is exactly what I need. I will have a 30A plug to plug this into my manual transfer switch for critical circuits.
This combo would work for outdoor parties and the components could be made to fit on a bike trailer for camping
Brilliant concept & execution. Thanks for tsking the time to shoot this & share 👍
WOW,WOW,WOW.... I'm just about to buy the bluetti ac200 max but after seeing this I'm torn.... this is 5000wh compared to 2000wh with the ac200 max this has a 3000watt inverter compared to the 2000watt ac200 and this is capable of more solar more ac charging and I can add MUCH MORE watt hours in batteries all for ABOUT THE SAME PRICE. the only plus I see with ac200 max is compact has 12v and looks cleaner....... I don't know what to buy now..... THANKS ALOT!
It's important to note too in the decision process, that the Bluetti is significantly smaller and can be picked up. While this cart wheels very easily, you can't exactly lift it up (has to weigh 150lbs or so) without 2 people. :)
I was close to ordering a ac200max a few months ago, but finding it only had a solar input of 15 amps stopped me, would need panels to be wired in serial, in an RV, you often can't get all the roof in the sun and that's a big problem with serial hookups. Other than that, I think it's prob about best "solar generator" out there that I could find. I plan on a Growatt, Mpp or Signature Solar has a new all in one too and need to hear more. about.
It's funny to see the epiphany, some potential DIYers have. A separate system is always gonna be cheaper for the same output than a "designer" plug-n-play one. Even better you can save more money if you decide to build your own battery and combine it with an inverter and other components that correspond to the voltage and ah of the battery.
Consider buying a EcoFlow delta pro. It’s about 3600 Wh of LFP battery.
Having separate components is very smart because if one fails you can just buy another inverter, battery or whatever .
Commentary is incisive and overall inspiring. Thank you
I think a good add on would be a led light on top. If power goes out, it would keep you from fumbling with a flashlight while getting it into the house, hooking up what you need to run, etc.
I love this idea! Very frustrated with all the options by bluetti or echoflow due to the cost. love this DIY and you have given me confidence to do it!
Great stuff ! Love it. To make it electrically safe and compliant, you are are required to add an RCD protected power board instead of that black one you have. Also a 6mm2 earth lead connected to the inverter, that you can roll out and connect a portable earth electrode to and bash it into the ground. This is extremely important. If the outer case of the inverter or trolly were to become ‘live’ and someone touched it, this would prevent electrocution, otherwise the human body would be become a part of the circuit to ground. Gotta be careful with these you tubers !
Why don't any of the self contained electric "generators" have the ground bar like you're talking about? Serious question, I don't know much about the stuff
@@WideAwakeHuman they use a plastic case
Can’t electrocute ur self on plastic!
In a power outage, would leaving the AC input connected to the house (although there is no power from the grid) provide the needed grounding, The AC Input has a green lead that is connected to the green of the house. If with a multimeter check continuity may make sense.
@@WideAwakeHuman A domestic generator (used at home) does not come supplied with this earth spike. So Joe Soap doesn't use the earth spike. But, if you work in the mining industry it is compulsory to have an earth spike attached to the generator that you hammer into the ground.
@@IsmaelMartinezPR Assuming the house is properly "earthed/grounded" (in other words an earth mat buried somewhere around the house), then YES, the earthing/grounding would be sufficient!
I love how clean and adjustable and reusable your setup is! Nothing is permanently joined with welding.
One adjustment for even cleaner setup. Use velcro stripes instead of tie-wraps.
Peace!
you could use a metal hose clamp to attach the battery handles to the cart. that is a bit more secure than zipties. You could also bolt a piece of angle iron to the bottom of you cart, for the battery to rest on.. It would prevent the bottom of the battery from shifting forward.
Oooo metal hose clamps are a great idea!! I thought of a simple L-bracket at the bottom but the bottom of the cart needs to sit flat to keep the wheels up, so having a bolt underneath wouldn't work. I suppose you could counter-sink it fairly easily - that might work.
@@LithiumSolar LOL, I was looking for a comment about the zipties. When I use them in my videos people don't seem to think highly of them :) Although I find them to be highly effective, and reliable.
Zipties are approved to be used in aviation. They sustain extreme temps, vibrations, and don't damage delicate surfaces.
I just finished one with a Growatt and the same battery but with the addition of a breaker box that allows me to use the full 25amp capacity thru a 30amp receptacle that my camper will plug into and I added a male electrical plug to receive a cord for recharging the battery.
Just did this set up a few weeks ago works great. We live in a 5th wheel with some land we have 10 410watt bi facial panels and growatt 3000es it powers the whole 5th wheel including the 13.5btu ac during the day and have enough battery to run all basic appliances during evening hour's. We do have to turn some things off with higher loads not a big issue we will probably do split phase with another growatt in the future. If you have the space to do it just do it you'll be amazed what solar is capable of. Pay back period for us will be less than 2 years.
Great to hear for RV usage , what type of solar power is regenerating and how long to charge?
@@mikew2046 I'm producing about 20kwh on a full sunny day and recharge takes about 4-5 hours roughly depending on the power being drawn Im sure I could easily charge 2 batteries on a sunny day if I an extra.
Very down-to-earth and straight forward. Great video, awesome teacher
How am I just seeing this! Great step by step for the first timer wannabe portable electronics guy like me. Can’t wait to watch some more of the videos. Glad I found here!
I like your build enough that I plan on making one myself. I figure it will run a pellet stove for a long time if we get a bad blizzard that knocks out the power.
Three hints on your build. If you can cut the strut in between the slots so that it cuts down on the sharp pointy edges. As you tighten up the ty-wraps pull them around to where the cut ends are out of the way where hands/arms and other soft tissue will not contact them. These ends when cut tend to be sharp and will cause cuts, even the small ones will cut you. If the solar generator will be outside very much, consider use black ty-wraps as these are more UV resistant.
Brilliant, yet simple! Exactly what I am looking for in an emergency backup to run refrigerators and a freezer, and charge with solar. Holy smokes, that's up to 4500W of solar input! That's awesome. Thanks for doing the video! Can you make a solar panels recommendation?
Consider using your vehicle to power your refrigerator after opening it. Best to have a top lift lid for freezer so cold air doesn't flow out as much when opened. Keep fridge and freezer closed and off as much as possible. Organize it to minimize open time.
Learn to preserve foods without a fridge or freezer. You will be golden.
👍👍👍
@@wellnesspathforme6236 One thing most ppl don’t realize is that a manual defrost freezer uses far less energy than a frost-free freezer. A frost-free unit is, on average, 34% less efficient. That’s a big number. Especially when powering from a solar generator.
@@wellnesspathforme6236 I agree with your comment about learning to preserve foods without refrigeration. Everything from properly storing grains, to vacuum sealing, to pickling, to dehydrating. One of the important things I’ll use a solar generator for is to power my grain mill. Yes, I could use my hand-crank mill. But it’s time consuming. I live in southern AZ where the sun shines 360 days a year. I’ll plug in the solar panels while I’m baking my bread.
Found out the hard way solar packs a punch when you get shocked.. I'm slowly learning electrical.
As a young apprentice electrician, I cut PLENTY of 3/4” unistrut with a hacksaw. Cut through the U and score the inside and it brakes off pretty easily. Works on 11/2” to, but you’ll be there all day and it can get wavy. I like this contraption!
✊🏾
Maybe I need a better hacksaw then (or at least a different blade) 🙂
Thanks, good idea. I had to build one. I ended up cutting off one side of the bottom U-bolt's threads for clearance of the inverter fastening holes. Pinched the u-bolt in a vice so it's tight around the dolly, and the one nut held it on very well. Unistrut caps are also a nice touch.. but at $5 each. Or you could use some large heat shrink to cover the struts -or both like I did
I bought a bag of strut end caps on ebay for about $10.
Good buildout, would like to see a 220v split phase inverter as well as a generator transfers switch for a whole house cut-over. At least a 50A setup so you can run your AC/Fridge and some lights.
You might be able to fit a split-phase inverter; however, think this is about the most I'd want to put on the cart. It can hold the weight but it gets bulky to move around.
That would be great, and the battery would fail in about 25 minutes. 🙄
You need atleast 4 of these batteries for a split phase inverter to even make sense
I built the 24 volt version of this, and yes, my DC circuit breaker is about the size of a shoe box! LOL. I made a few changes like adding am 800lb working ratchet strap tie down ($6) to hold the two 12 v 206 AH SOK batteries in place. I also used a 2 x 4 in place of the bottom full-size, (no drilling) not 1/2 strut, secured with 2 hole pipe clamps. I did not need to drill the Growatt and the back of the 2 x 4 holds two 20A GFCI outlets and the PV circuit breaker. Works great! Thank you for the inspiration. Good Job!
I will take your word on how it works. One of the best, if not the best video that ive ever watched.
Hey! I just did that today in the forest! I moved everything to the canoe, then onto the dolly, then up the hill to cut some trees. The 1800W chainsaw works well, but this is very hard physical work! By the end of the day, I was able to charge the battery back to 100%. It's very heavy and a bit inconvenient (the chainsaw with the cable behind), but I can repeat the process each day without going back to the city or gas station. I think the benefits are far greater than the work to move the weight. Anyways, within a few years, we should have better equipment and batteries after we invested in this transition technology. I hope to see the day when it becomes stupid to use refined gas instead of raw energy coming right at us... I use a few ratchet straps (reusable) to fix the battery and inverter on the dolly. You can also put the inverter/controller sideways with a strap or two, no? I also use double sided velcro to fix cables, they are reusable as well if the setup is temporary.
It sounds like you have a sweet setup. How do you charge your battery? Do you haul around solar panels too?
@@eradicator187 At 23 kg per solar panel, I leave them in the rack! I just carry the battery back to the cabin and connect it directly to the charge controller.
And make sure you dont use ANY products like tires, cosmetics, plastics, etc. made from stupid refined oil/gas.
@@joerivas9847 can these batteries be recycled ,, i think not ,they are a forever product once built ,, meaning you have to just throw em in a dirty big hole ,, maybe they can fill those big mine holes with em ,great for the landscape ,,
We live in a fantastic time for dependable energy, you can power a house, from a handtruck.. another excellent build. Thankyou for sharing. And I'll agree with others about the tires. Solid core tires with decent bearing will last forever.
Well not really 5kwh is hardly enough to power a realistically sized residential dwelling
You can add another battery pack then you will have 10KWh which is more than I what I use on my 1600Sq home per day. and it is great for rolling black out here in Cali.
@@budmartin3344 the only time I use 10kwh daily is in the cooler months. Texas is hot. Not everyone lives in “Cali”
@@Armenian Well, you just have to build your backup system based on your needs, no one size fit all. I have 10KWh system for my backup and it fits my need just fine.
@@budmartin3344 i understand this. And hence why I mentioned that 5kwh is hardly enough. You’re looking at a 30k+ investment just for energy storage alone. Not including panels and split phase controllers/inverters & wiring.
I really appreciate your explaining clearly on the Mc4 extension. I'll remember Pointy to negative. Just bought the EG4 with battery and planning to follow your very well easy to follow video. Mahalo.
So cool...I am going to try building this awesome backup system.
In my neighborhood, there's always power outages.
Thank you for sharing!
I'm trying to learn about going solar (perfect for where I live, in the desert south west).
Unfortunately my knowledge of electricity is minimal, to non-existent (replacing outlets, switches, and installing light fixtures is all I've ever done).
That's why I love you, and Will.
Your instructions are extremely easy to understand, and with these all-in-one systems, makes it even easier.
But don't worry...I intend to find an electrician to make sure that it's correct.
❤️🌵☀️⛈️🌈☮️🐎
Excellent presentation. Is there a video that shows how to build the solar array for this power station if I want to use it on a daily basis?
Quality parts UL listed too, good instructions, Huge plus for using 48v. Nicely Done🇺🇸👍🏻
You've got the right stuff, dude.
Possibly a good idea to add a set of dummy clips for the solar connections you could use 3m clips to adhere them to the side of the inverter to both secure the cables further but also keep the solar connections clean from dust and dirt on field deployments
love the handtruck!! that's a heavy battery😮
compared to the light weight Growatt!!
also like the PV connection
, the Growatt is a little tricky to access
a few extra inches between the battery and the all in one unit could help!
I got to use this system this am when someone hit a utility poll up the street!
first time I needed bigger load and it worked like a charm !!😊
I probably won't ever do one of these, but it sure was fun to watch. Thank you!
Okay, I changed my mind, I am building it.
WOW, perpetual power...as long as he keeps walking with his little wagon.
"positive lead goes to positive terminal", brilliant
Not Everyone understands "Electricity 101" however, so, while "Redundant" for us, it's still helpful, and important, since he's not shadowing each of us building one!
@@robertweekley5926 Awww. You so butch!
Thanks for the Build and reviews, and the prices! Freakin awesome stuff UL also.
Thanks! I copied your idea, but used a MPP2724 with outlet plugs built right into the unit on the side and MC-4 PV input plugs on the bottom, and I built a DIY battery using 304Ah cells (24 volt) and Daly BMS with the 2A active balancer. It works great. We are using it in the Green house for now, later in the RV when the weather is warmer, and in the fall time we can use it around the homestead while we get ready for winter. Handy to have power anywhere you need it SILENT! unlike the gas generator we used to use, that is LOUD, smelly and expensive to gas up. Great project for anyone with a few basic tools and skills.
I already purchased from signature solar and I am not happy with them. I have inverter that I can't use until they send me a data cable and I don't own a computer so I have to find one and borrow it and I don't have internet so then I have to go find that it's just ridiculous this is supposed to be plugg and play. Anyhow I like the idea of the inverter that you bought but I would like it bigger. I already own three of the eg4 batteries and 14 of the 455 watt solar panels.
I brought four of the panels with me back home and the other 11are up at the cabin.
I have a growatt infinity 1300 power station which i like, just doesn't last long. So i started researching how to increase my battery capacity and fell down this rabbit hole to make a cart system that basically works like my growatt using the eg4 batteries I've all ready paid for.
I like the idea of the built in plugs of the unit 2724. Does ut come in a more powerful unit? One that will take more input from solar and one that will export more power so I can run like a window AC unit and hook up additional batteries?
Really nice and well thought out design. Great component selection. WELL DONE!
Having endured the catastrophic ice storm in Texas, I am researching to find a solar back up. Now, I am already hearing of power outages in our state and something like this would certainly bring peace of mind. Great job!
I bought a 13k portable generator that runs off propane and gas and I keep a dedicated propane tank just for it. I'll be building a solar setup as well just to get off grid as much as possible. Best of luck in Texas from us here in Arkansas.
Thank you! God bless your endeavors!
Wow THIS LOOKS NICE I’m a newbie and have put together a 100 watt kit this weekend
Just to get started
I’m ready to make sure I step UP and this is very affordable
I’ll probably go with this exact build THANK YOU
I think it's a very good build myself there's other inverters out there but I'm starting to like the grow watt.
Nicely, done. Thanks for sharing a clear design process.
running the growatt 3k. same bat.. one cable and they communicate! . wall mount, it runs my whole house 24/7 with 1,300 watts pv.. big fridge. toaster. electronics. electric blankets... could charge from the grid ... but no need . luv it signature solar.
While I understand not adding plywood to the cart I would think at the very least a strip of rubber membrane tape should be added to each rail on the cart prior to cinching the components to the cart rails. This would provide a sort of non-slip surface to prevent the components from any amount of slippage plus protect the rails from abrasion.
How about a pool noodle for vibration absorption. 🙂
yes! you were able to turn the sound off. thank you so much for this tip, I hate the loud beeping. awesome build!
Yes! It's so obnoxious. I have no clue why that comes defaulted "on" for all of these inverters...
Man .... I was building on a wagon with a full DC/AC output interface but this, this is so much cleaner, more compact, and easier to put together. Nicely done :)
you did a really nice job.. it's almost plug and play!
Connector biology 101: Pointy=male, “rectangular”=female.
I’m working on a similar build. Thanks for the ideas!
Connectors are a bit more complicated than that, unfortunately. Gender applies to the electrical contact, not the plastic shroud. If you look inside the shroud on each MC4 connector, you'll see inside the round one a "large" open metal part which receives the mating connector. This is the female. The male metal part in the rectangular plastic shroud is smaller diameter to fit inside the female, and sometimes is open on the end and sometimes closed.
@@Sylvan_dB And that's exactly why I called them "pointy" and "rectangular" LOL. The pins are opposite gender of what you'd expect by looking at the plastic housing. Calling it "pointy" sounds silly, but it's difficult to mix them up that way...
Would be nice if there were red and black connectors
I really liked your video. you made it look so simple to put together. I want to build one for myself but I would like to know if you would recommend any changes to the hardware you used from the time you made your video, and what is available now.
This was great and is now my model for a portable unit.
I already have a Bluetti AC200P that I use to run my fridge, freezer, and modem/router.
Your setup will give me what I need to run a window unit.
I live in Texas and have been to Signature Solar to purchase a panel. I need to make another trip back for these parts and more panels.
Thanks for all you do!!!
Which solar panels do you use to charge your Bluetti up with? I use (4) 200 watt Rich Solar panels to charge mine.
@@ImASurvivorNThriver I use a 395w URE bifacial panel.
This is fantastic! far more utility and portability using the same parts in a house system!
Awesome. So the goal, if I understand correctly, was to make this pricey setup more functional as both a solar power system and quick disconnect from solar array to be used as a portable/backup power when desired? Seems well suited and easily pulled up a simple ramp into a p/u truck or trailer for offsite power, fun wknd portable power at beach, campsite, jobsite, etc. I have used a similar dolly setup for portable dual high velocity 22" fans with mister system for portable cooling in scorching Tx. This for RV class C solar setup, hmmm? Perhaps laid down in an outside storage compartment? Roll in / out horizontal? Specs of the 100 ah 48 volt EG4 battery is 109 lbs. I would also have connections to EG4 inverter/controller for my Onan generator and truck alternator beside solar array. Feasible to have those easy quick disconnects? Guess just nut release?
Such a good video thank you for making it.
Thanks for watching 🙂
I'm SOOO tempted to build this!!! In an emergency, it seems pretty easy to run extension cables from it to my fridge, computers, etc. vs. trying to wire a backup system into existing wiring, cutoff transfer switches, etc.
Very cool build! I like the use of the channels and u-bolts. I have a portable setup that I will be upgrading with those components! THANK YOU!
Maybe place a small block of foam on the bottom blade to cushion the battery and perhaps line the cart rails with pipe insulation to help prevent marring of the battery case. It would probably make the battery less likely to slide around on the red metal rails.
Nice build out. This is actually a deal. Solar generators are already starting to increase in price.
Thanks. And yes, everything is increasing in price unfortunately... I just ordered several feet of #4/0 cable last night and had price shock 😧
I have not even watched the video and already love the idea!
Was thinking of the very thing a few months back as I have a similar setup.
Excellent design. I plan on buying a used Nissan Leaf and charging it using a similar device with a 7000 watt lithium cell, 12 volts and 3KW, pure sine wave inverter. Mine will be a bit larger and horizontal but still very much like yours which is pretty reasonable and appropriate.
Great build. I build my first after watching your earlier videos but its only 2400w with 2400w inverter. Maybe time to build another one. Just need to hide the receipts from the boss lady.
I like this.
A few things I'd do differently, call it the benefit of hindsight.
- position zip ties so the sharp cutoff are less accessible - less chance of cutting hands. (also use flush cut sidecutters)
- dual pole isolation switch on the solar input cables.
- mount a water proof switchboard cabinet on the trolley, then mount the components inside (yes this increases expense) the weatherproofing on this will be needed as I'm expecting it would be used outdoors for (say) camping, building sites, etc
- I dislike zip ties, find a different bolt mount system, I'd look at threaded bar and channel to clamp the battery in place.
but those are really cosmetic issues by comparison to the fundamentals. still good design.
thanks for creating and posting the video.
One could also drill a hole in the hand-truck (trolley) frame and put the cables through the frame.
x x ...I'm planning a similar build. Can you recommend a specific "water proof switchboard cabinet", and what parts would be inside? All of it inide one case would require...basically a small closet. I looked on Amazon, and it's not easy to sort by dimensions.
Another outstanding build.
Really nice setup. thanks for sharing.
Nice job and a well done video. One question, how long did it take to initially charge the battery?
Really nice. Also perfect for a construction jobsite. No need to erect a temp power pole etc.
Nice clean build! Thanks for sharing!
Clean assembly and super portable.
Great build, great video! As all-in-one solar generators get heavier, I think they may start using this form factor. The little wheels used on the current models will have to become heavier-duty and need metal axles, etc.
Well doo)e. I like the double use of the power strip for input and output. Same thumbs up on the Anderson cable. Nice ideas there. I would like to see a framed box at the foot of dolly for the battery to rest into. I fear a big bump may allow latteral movement with risk the battery may pop off the dolly (small chance but not zero). Or maybe double sided tape? Super build. Good price. Thanks for sharing
Or a Ratchet Tie-Down Strap.
That's actually badass for people that use camper covers / need a small package.
Thank you for doing this hand truck build with these two products because it was what I wanted to do and now I can reference this video when I build my system.
Update: Just finished my hand truck an hour ago using almost the same components used in this video (Growatt 3000 Inverter, EG4 24V LifePo4 Battery, Milwaukee hand truck, etc.) ... took me about 12 hours because I had to cut out wooden planks using hand-saw, go to store two times to buy mounting parts and hand truck, and when I came home from shopping battery was finally delivered just in time for me to build it all. Also just make sure to follow each step closely in this video and use a resistor to pre-charge your inverter before turning it on so electric sparks won't happen. Thanks again for the helpful video!
Excellent information. Since portability means you might be moving this at unexpected times, I would fashion a waterproof cover, which would also keep the dust out when not in use. Tall garbage bags would do in a pinch and are cheap and lightweight. Adding a LED headlight (rechargeable) would help if grid power goes down. A bag of extension cords tied to the bag would come in handy. Larger tires, solid core, might add to the weight but would help going thru puddles, shallow water. If you use air tires, find a place for an inflator pump. I’d consider swapping out the power strip for one that has USB charging ports, or just add a second cheaper one.
Dude! Sounds like a sweet tricked out rig!
Princess Auto sells foam filled airless wheels.
Integrated USB ports get outdated every 5 years. They are a gimmic. 5 years from now USB A cords probably won’t even be included with any products. USB C are the new norm and most power strips don’t have USB C. Independent chargers are cheaper and usually must faster
@@Dr.LongMonkey I’ve been using USB ports for the past 10 years.
@@danlux4954 must be fun waiting 5 hours for your phone to charge. Meanwhile I’ll take my 1 hour change time
I like it that's pretty good idea really there are fancier hand carts that cost more but ones that have another wheel at the top too so they can be rolled around in the horizontal position also
Very good built and simple.
Wow great video, haven't seen your content for a very long time. Always enjoyed to DIY projects. Congratulations on 1 MILLION Views !
I have this same system running in my RV. You can power a 15,000 BTU Air Conditioner without soft-start. The Growatt is kind of a power hog though.
I would love to see some testing. How many panels do you plan to have for this? The specs seem to indicate short strings.
A new video is up showing the solar panel connections 🙂

Great video. I might build that. Thank you for the video and the walk-through.
Hello from Australia. What an amazing set up !
Maybe, if you can find it a power strip with 20 amp capacity that also has USB ports built into it. If not, then just go and buy a good 110 small charger that has PD for USB-C & USB-A
Great setup! At a cost of 3k I wouldn’t just keep it on standby in the garage. I’d throw a few solar panels on that bad boy and take a few loads off the grid. The cost of a few panels is not much more as it relates of the current investment. The of Roi might not be huge but it in the case of increasing rates or leveraging time of use rates it good be. In theory you shouldn’t have to worry about life cycles on the battery or other expense and maintenance.
Lol
The first step I would have performed would be to flip that EG4 cover in order to make the presentation look more uniform. Great overall. Thanks for the presentation.
Believe it or not, I tried that... it doesn't go on the other way, the screw holes don't line up unfortunately.
@@LithiumSolar Ha, I stand corrected! Thanks for your time in producing a quality video.
I'm impressed by this...really like it.
I had considered making a dolly pack like you have before I saw your video and the components I wanted to use were exactly the components you used. I feel better about my choice now😊 With 1200 watts of solar panel connected to this system. How long do you guesstimate that system may run a 7000 BTU (about 6 amps at 120v) AC in Phoenix AZ (very sunny) ?
about 6.5 hrs if the unit is on full time?
Suggestion: Put your power outlets as close to the ground as possible (Obvious reasons). Use the entire length of your zip ties, especially on heavy loads -not just one turn and cut off the access. Don't waste the tie. USE the access length and double / triple / Quadruple the holding power of the tie. Put rubber feet on the D handle to help keep the dolly from rolling when you lay it down.
I would also flip the battery over, so the terminals are closer to the truck, the positive and negative leads don't cross each other, and the breakers become easier to access.
@@ES-mq9ox you go around with your ty a couple of times before you set the tie..
@@ES-mq9ox Try it. And you'll see.
@@ES-mq9ox In addition to adding strength every rap puts less stress on the teeth that hold it together.
@@ES-mq9ox You're wrong. Take a 12 inch zip-tie and lock it off forming a loop. With your hands, pull it apart. Note how much force that requires. Now take another 12 inch tie (same exact kind) and do the same thing except double it over after you close it forming TWO LOOPS. Now try to pull it apart.
This is a very powerful portable power station.
