Will I've been in prison for fifteen years and finally parole in a few months. I've watched every one of your videos and everything i know about solar power is because of you and now i hope to get a job with a solar company once free. I owe you big and just wanted to say thank you!

These are the kind of videos that I love. Grew up poor and even with money now, I still prefer anything DIY to save $ for the unknown.

I have been saving for months to build a system like that, but with a EG4 Lifepower4 battery, and I am almost there. Thank you for posting this video. I know I am doing the right thing now.

Smart person in providing technical content✅

You are the best source of real life useful info on components. Love your content.

I love that you went back to your roots with this video. Please keep it up!

This system, as you said, is a match made in heaven. Looking forward to the parts list.

Nice setup! When that EG4 unit first came out this is the application that first came to mind. It's the perfect combination of specs, price and size.

Fast, detailed for the novice, source of supply provided, contrast and comparison to other all-in-ones - EARNED MY SUB!

Thank you for putting up with me over the years. With this video, I finally came to understand that I could do this, ordered the components and built it! I used two EG4-LL batteries instead of the single Trophy for 10k of storage. All systems nominal.

You just keep coming up with solar stuff for me to spend more money on! Great video, as usual. Thanks!

I made this with a eg4 and am very happy with it. You can load it into your vehicle and use it instead of a generator on job sites where 5-10 KWH is enough for your day’s project. When I tried to start a medium- sized compressor the 5 kw battery would fault. A smaller compressor,however,worked just fine. I feel that with 2 batteries there’d be no problem. Since most of professional construction tools are battery operated,including even miter saws, all many of us need is a way to charge batteries. To be honest,I am retired and am ready to quit when the first tool dies.

Oh thanks Will, this is exactly what I need and I have little funds and will need it mobile for a while, so good and perfect timing. It also gets very cold in winter here so the Trophy battery with the heaters are what I was wanting, again, so perfect.

Been waiting for a new video on this topic! Thanks!

This is the type of content I like to see. Thank you!

FWIW I came here for information on the EG4 all in one and you answered my question fully and clearly. Thanks alot. Always amazes me how hard it can be to find specific info in this day and age of information.,

Will, just wanted to thank you for your videos, and yes I bought your book also. This video is just what I was looking for. You explained everything spot on. And that is why I watch your videos. Thanks.

I just finished a portable system. After watching many videos and getting ideas from different people I did a small 300watt system with 2 100AH lifepo4 batteries with plans to add another 100Watt panel in a few months. I installed it on a Harbor Freight 4 wheel aluminum cart. I really appreciate the youtube channels for great ideas and this channel for getting me started on solar backup.

I want to build a 12v battery box for remote radio ops. As always, I see how much I need to think about to do it safely and correctly and still get the desired results. Thanks Will. You're the teacher I need right now. I'm going to share this build with my radio club.

Will, you're always such a great educator and resource, thank you so much!! Bless

Thank you. Looking forward to the parts list and blueprints. I am trying to size up if I have the skills and safety knowledge to pull off a build like this.

Awesome build. Definitely way better than pretty much anything on the market

Ha! This is exactly what I did. Worked great during the last hurricane, and was able to move it to some friends houses so they could keep their fridges cold, charge their phones, and run some fans and lights.

Great stuff. Wow! Great illustration of the DIY vs pre-built in terms of stats and $$$.

Love this! A great way to start entry level solar. Thanks!

Thanks Will,you a Star. Your understanding of everything solar is great for learning, putting things together. Thanks prof. 👍

Glad your back Will and thanks for the update on the cart. I’m planning on building this with the eg4 inverter but still not sure which battery. I want to power my freeze dryer and want the grid to be my backup to the battery when it’s dry. Hope that can be done somehow. Keep up the great work 😊

Brilliant video - thanks for all your hard work in making it easy for us to copy. I feel confident to buy and build this one.

THANK you Will! Straight forward and very clear. Thank you for all that you do. CHEERS!

I built one using all EG4 battery and inverter on a plywood cart that can use 2, 5 KWa batteries. Great setup, and I can use the 14KW diesel generator for daytime use to charge the battery, and use the battery and inverter at night silently for lights and refrigerator, freezer, and gas furnace.

I just finished the same build about a month ago using the EG4 battery. Works great and highly recommend!

I am doing something similar using the EV4 6K split phase inverter and 2 of the Power Queen 4.6KW server rack batteries ($1199 each) to run a well pump. With the cart, it is about the same price as the EcoFlow! Great idea and video!

I'd say the homemade one is definitely more convenient. It's easier to move around because you don't have to bend over, plus a handcart is specifically made to move heavy things easily.

I love my EcoFlow Delta Pro. I have 2 sets, DP+EB. I needed the plug and play because of my knowledge and skill level when I got the EcoFlows in the kickstarter. --- NOW? I'd 1000% do this. My biggest regret with the EcoFlow, is the limited solar input, especially on cloudy days. Thanks for another brilliant video, Will.

Perfect time for this, I have been on the fence on building my own system with everything out the now that’s pre-built I was thinking that’s the way to go. I like scalable, flexible, and costs less for more. Thanks Will👍 ,

Long time no seen thanks for another video, your the best !

Wow. This totally just made me start rethinking what I thought was going to be the easy out. Thank you!

Nice build will. Simple yet useful.

Good video Will, I made something similar a few years ago but using AGMs, LifePo4 batteries are so much better. They lighter, more power density, greater discharge rating, the only drawback is cold weather use. For those who run into the IEC "European" color wires Brown = Hot, Blue = Neutral. Stay Safe & Good Luck

way to go keeping it simple. Very thoughtful, Will.

You just talked me into building one this week. Great content.

Awesome Will... Seriously considering this system for emergency backup power! This is so easy. It's off da chain cheap!

HEY, KIRK HERE; THANKS BIG TIME, for all the Data: I have been following you for like 3- years, and you are always on top of all new sources! Again Thanks. KIRK'OUT'PEACE

Building one of these right now and I love it!!. Won't be the last for sure.

This is so cool and make it so easy to venture into. Thank you.

Was thinking of you this week. Bought a golf cart. Adding the all in one charge controller liFePo batteries. Will be able to weld and work all over the ranch.

After watching your original EG4-3k review, I ordered and built one. It has been running flawlessly. I actually added additional batteries and it has been running great. I use it to slow charge my EV Kia. Thanks for showing us how easy it is to make solar systems.

Fantastic! Thank you so much, Will!!

I literally just finished installing this inverter and battery combo in my travel trailer with a 60amp converter. It rocks! It'll fire and run the ac for a good 3hours if I want. Next upgrade is 1600 solar

Will Thanks again for making this so easy to understand. I plan to do this soon. Keep up these great videos brother👌

This is the video I've been looking for. I haven't invested into a purchasing a hefty system. I've seen other videos with this design. Seeing that you have done this build now encourages me to go this route instead of buying a commercial made system.

Just the sort of content i like to see!

Thanks for helping me find the right inverter. I just placed my order.

Great video Will!

thanks for all the great videos

"buy a second inverter and put it in an EMP bag! " Will, are you preparing for the worst? Great content in this video. Thank you.

This is great Will, going back to the folks who wants to start small.

Great video Will thanks for the build!!

Since I only use my power station for outages, dragging the large solar panels out of storage would be a down side. But that looks perfect for a cabin or entry-level off grid system! And the price is right too! Thanks Will!

You videos are great and inspiring! Thanks for your hard work and sharing with us!

Thank you I will try to build this!

Thank you!! The math always worked on battery chem comparisons, just not the total dollar count for us. I could not wrap my head around all the components. Then you started the all-in-one reviews, and these last 2 vids on these builds. Finally with the cost made sense instead of paying for the simplicity of the commercial unit. We started 10 years ago with a Goal Zero Yeti 1200, replaced a battery after letting it discharge to 0%, adding a 2nd. I liked the info it gave, and being ready to go. Finally, DIY might be both the cost and “head-wrapable”(?)🤣

This is awesome!! I think I would mount a piece of 3/4 ply on the hand cart, then mount everything to that, but I guess you have to drill through the cart tubing either way.

Hey man! I just built one. Thanks for the videos, I certainly appreciate it!

Will, you are awesome. Thank you for this post with easy set instructions. I just ordered this and shipping of course is expensive, $1,223 a reality living off on an island from the other 49 States. Shipping cost $1223, still cheaper then purchasing other solar generators like the Mango (has problems) or the $3,699 (not including shipping cost) comparison unit on your video. Plus Signature Solar company is handling everything yahoo! Total $3,415.

I like it simple! Great video

I'm disappointed with my EcoFlow Delta Max 2000's. They were great but after two years of using the SoC is 84% and I only use them as eps units when I travel out of town or when we lose grid power. This video is my answer. Dealing with EcoFlow Customer Service sucks. Thank you for this video. You have given me the confidence I need to do this diy system . Thank you for sharing your wisdom.

this is exactly what i plan on doing i picked up a delta 2 and EB for home use but now its going in the camper and ill build this for home use

Finally convinced me. Just purchased the whole system.

Great idea. I would maybe do this with one of those hand trucks that converts into a 4-wheeled cart.

Thanks Wil appreciate the info getting ready to start my build and you always give great information six stars brother

Signature Solar has the best customer service. I received the EG4 3kw and the EG4 48v battery a few weeks ago and just ordered the Blue Sun 460w Bifacial panels. I did not know they gave a military discount when I ordered the inverter and battery, so they gave me a refund for the amount of the military discount. That is what I call EXCELLENT CUSTOMER SERVICE.

I'm glad I found you always have great information I'm going to do this in my cargo trailer with panels on roof mini on the tongue

perfect system for my cabin upgrade. 400 watts is just not enough. Brilliant. Thanks.

I love it, low cost and more power that would work great for my offgrid storeroom.

Really happy with the 3000evh. I bought a second one during the refurbished sale for 500.00!!!

Will, what a cool innovation using the most basic but coolest all-in-one paired with a modern server rack battery. This blows the EcoFlows and Bluettis out for many of us in the market that are more than willing to not pay the premium for the fancy packaging and smaller size unit to instead get a scalable and cheaper (albeit less elegant) solution. I put together such a unit using the same all-in-one but with their battery, not the Trophy. I'm a big fan of Bluetti, but this is the way forward... Couple of notes: - I suggest using a heavier duty gauge output cord, given the potential of a 3kW output. I settled for a three way 10AWG splitter cord. I had issues with the suggested Yellow Jacket splitter box and wouldn't want to try to pass more than the 1875 rated watts thru it even after a few glasses of wine. - I also suggest using a 10AWG cord for the AC input cord. This thing will max out my 20 Amp AC wall outlet for a while when it is hungry, just sayin that'll get warm with thinner cords, and you almost feel like you need to be around when it's doing this. LOL. You can adjust the AC input voltage down if desired. - I had issues with sudden shutoff (and unsuccessful support calls) before I hooked up to AC in (with a proper ground). If you don't have a proper ground, this unit will possibly not be happy. After I grounded properly my shutoff issue went away. For many of us the whole point of a hand truck system is mobility. That's fine with this amazing design. Just bring a ground cord setup along for safety and reliability. I use an old strand of Romex that is attached to the bottom of the inverter and then runs to an iron stake deep in the ground, attached by a pipe clamp to the wire. Also, They supply a Nader breaker for the battery positive line. Rock and roll, Will. But how fantastic to see how small this technology is getting. I think Signature Solar is a little behind in terms of marketing. If this were just a little more polished I could sell a million units in California. This was unthinkable not long ago.

Good stuff! Thanks for sharing.

Whew i been waiting for a new video!!!!

This is neat. And runn a window ac unit and solar hooked up to it is very awesome.

This is the build I've been wanting to see, thanks Will for posting this... Best regards!

Thanks. Very well presented and very well researched.

Much appreciated! I have a 16x16 cabin that this system would be perfect for. We don’t need much, but do want a mini split as we’re in Alabama and it gets hot and humid here! I’m not naturally inclined to work with electricity, but think I could do this. You’re awesome, Will! Love your videos!!! ❤❤❤

This is an excellent teaching video, thank you.

Fantastic build.

crazy to think you could add an additional battery and that would be around the same price as the ecoflo. heck of a system :D great video Will!

This is so badass. I need a way to mount the 3 400W panels. Thanks for the idea!

Thank You for another clear video 👍👍👍

Thumbs up 👍 thank you for the information.

Thank you WILL ,FOR YOUR RELENTLESS DRIVE TO DELIVER SUPER INFORMATIVE CONTENT! Thank s !Ron🤠

This video has gotten me motivated, but it’s going to be a work in progress. I haven’t commented in a looong time, though I’ve continued to watch all your videos. This winter I’d decided to return to Arizona-been on my list since 2001. Anyway, with summer temperatures rising I’ve been contemplating installing AC (or mini-split) in my van. This EG4 and Trophy combination should work fine, only I lack roof space for mounting an adequate solar array to keep the system charged. Thank Will!

Great haircut! Looking good Will!

Awesome! Thank you!

I completely agree with you that this is a much cheaper and more scalable system. What ecoflo and Bluetti need to realize Is many people can make this themselves but many would prefer buying one ready-made if it's financially comparable and scalable.

Would you mind adding a link to the 240V version of this build ... I would be very interested in something which can handle the surge and load of a Grundfos Well Pump for backup purposes

Very impressive Will thank you 😊

Great Vid. Very informative!

Thank you, Will. 👍🏼

Perfect build
