[@joneslr25]

Can you provide more info about your setup?

[@VinceBadovinatz88]

Nice

[@patrickkenny2077]

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.

[@davezell6442]

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.

[@Spenny99]

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!

[@smjewett]

I am very thankful you are so thorough in your procedures. I wish more people on the tubes did it like you!

[@dropshot1967]

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.

[@LithiumSolar]

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.

[@BradCagle]

@@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.

[@troyyarbrough]

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.

[@whoanelly-]

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

[@troyyarbrough]

@@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.

[@j.malone1293]

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.

[@ItsEverythingElse]

@@whoanelly- For something movable like this, with a metal cart, 24V would def. be safer IMO.

[@eddiekytia]

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!

[@LithiumSolar]

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. :)

[@putteslaintxtbks5166]

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.

[@gountzas]

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.

[@janaksodha9582]

Consider buying a EcoFlow delta pro. It’s about 3600 Wh of LFP battery.

[@Syncere20]

Having separate components is very smart because if one fails you can just buy another inverter, battery or whatever .

[@sholland42]

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.

[@VinceBadovinatz88]

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

[@scottflatland2766]

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!

[@putteslaintxtbks5166]

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.

[@francespueo5367]

[@POW2000]

So cool...I am going to try building this awesome backup system. In my neighborhood, there's always power outages.

[@Codger2015]

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.

[@alanesterline2310]

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.

[@amantin]

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!

[@theartofplumbing]

Very down-to-earth and straight forward. Great video, awesome teacher

[@koepketube]

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

[@russlo5324]

I bought a bag of strut end caps on ebay for about $10.

[@edmundgarcia3113]

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.

[@bousabousa2377]

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 !

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.

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.

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.

I would put the unistrust on the back side then use longer hardware to mount it. The weight would be in closer to the hand truck. I would also recommend putting it to use full time to offset the cost. Mount some solar panels and power as much of your house from it.

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.

[@LithiumSolar]

[@russlo5324]

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!

[@ProMovieBlogger]

Great video. I might build that. Thank you for the video and the walk-through.

[@buddysteele8220]

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.

[@blairdavis4048]

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?

[@ItsEverythingElse]

This is exactly what I need. I will have a 30A plug to plug this into my manual transfer switch for critical circuits.

[@TeslaRebuilders]

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.

[@loucinci3922]

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

Nice, simple design…well done. Watch those tie wraps when you cut them square…they cut you when you least expect it.

[@johnroyer3191]

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.

[@MatthewTaylorAu]

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.

[@joatmofa0405]

One could also drill a hole in the hand-truck (trolley) frame and put the cables through the frame.

[@737smartin]

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.

[@YouTubeviolatesmy1stamendment]

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

[@Bob_Adkins]

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.

[@douglasmontgomery6315]

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

[@paulatudor691]

Wrap the zip ties around it several times before pulling it through the end and tightening it. Makes the zip tie stronger.

[@americansfirst1095]

I will take your word on how it works. One of the best, if not the best video that ive ever watched.

[@pacman3536]

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.

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

[@zanedzikonski4234]

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.

[@TC-dk6do]

[@slowpoke1315]

Nice job and a well done video. One question, how long did it take to initially charge the battery?

[@charlestatakis9363]

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.

[@OutdoorsTech]

I really like your setup. I built a smaller one just for power tools and its been great. Really good presentation on the video.

[@migmigjohnson6083]

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.

[@gregory4154]

Nice build out. This is actually a deal. Solar generators are already starting to increase in price.

[@LithiumSolar]

Thanks. And yes, everything is increasing in price unfortunately... I just ordered several feet of #4/0 cable last night and had price shock 😧

[@EngineMisfire]

Another outstanding build.

[@peterbeyer5755]

Can I suggest that, - prior to trimming the U bolt that you thread a bolt onto it and use the bolt to even out any issues with the thread when you take it of - some washers and spring washers will make it more secure - hose clamps instead of plastic ties, - a rachet strap on both the inverter and battery when wheeling over the rough stuff.

[@RPRosen-ki2fk]

Awesome video, I loved that you priced it out simply and clearly and didn't make me go to a half dozen websites like other channels do. Do you see yourself ever going to the next level and building one capable of 240vac?

[@calmeilles]

A 48VDC to 120/240VAC pure sine wave inverter can be had for about twice the price of the single phase one used here so it would just be a matter of replacing that component and arranging suitable outlets.

[@dorzak975]

Do you want 120 and 240 both, or just 240? If just 240 there are inverters for the same price and sometimes a little cheaper intended for the European solar market. In fact looking for deals on inverters you have to be careful which one. For example one of the MPPT models the 240v model is $75 less than the same 120v model.

I'm sorry for all the questions but you've been a WEALTH OF KNOWLEDGE. Systems like the bluetti or ecoflow have an ac output efficiency of about 80/85% have you done real would test to see the efficiency of the growatt and eg4 battery. I'm buying the new bluetti ac200L for a semi portable unit but LITERALLY because of all your videos and help IM BUILDING a diy growatt and eg4 battery system for home emergency. Its scalability to add thousands of watt hours and even to add a 2nd inverter for more output is amazing....... THANK YOU

[@janaksodha9582]

Excellent video. I am tempted to make it myself. Recently bought a ecoflow delta pro 3600Wh. Your solution is more powerful and easily expanded I assume. Thank you for making this video.

[@johnb9825]

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.

[@serversurfer6169]

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.

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) ?

[@AGhostInTheMachine]

about 6.5 hrs if the unit is on full time?

[@r.b.l.5841]

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.

[@mycabinlife1291]

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?
