That’s awesome Jesse! I think solar is a great industry to get into. I think more and more people are going to want small off grid systems like this one in their homes for power outages (which seem to be more common everywhere). The big companies tend to focus on big grid connected systems, but you might find a niche doing small back up systems for people.

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.

[@deniseschnose337]

I just got this system & want to add the solar panels. How many did you buy? When I try to buy 3 it says the minimum is 10...

[@michaelbradley1636]

Signature solar had the best price for EG4 inverter. I am setting up a 48V system with 10 x 250W USED panels from SanTan solar, the panels were $50 apiece. I don't expect to get 250W from each panel, or course, would be nice to get 200W max on very sunny days this summer. The panels should be about 9A x 28 V each, so the 10 panels should be abut 280V and 9A max output, so the EG4 should easily handle it. I looked everywhere for any controller which could handle over 200V; the only one is the EG4.

[@EnFuego79]

@@markhelminger5597 I always keep it charged prior to the hurricane hitting. Also, it's pretty rare for all areas to have their power knocked out so it's highly likely that someone you know will have power to charge it. We also have a generator so we can charge it with that too - most people barely use the output of their generator; you could hook up 3 of these to a generator while the generator supplies power to your own house as well. Lastly, you can use panels in the aftermath when there's more direct sunlight, but that takes the longest. Hope that helps!

[@danielking2944]

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.

[@chrisE815]

Nice! Maybe a portable panel setup is in your future?

[@jerrellbevers6071]

Most tools of professionals are corded still if they work anywhere but BFE. I would not hire a crew to build my house or do work for me of any significant size that only used cordless tools simply for the reason you stated. Production requires a cord.

@@Seqhael There is no way you can keep up with corded tools and hoses with compressors. Anything else is a lie. Plain and simple. I've built houses for 30 years. I have thousands of dollars invested in cordless tools and 17 6.0 amp batteries. None of that competes with my corded tools but I still have and use them. They're getting closer and better but if you want real production and have access to power then you aren't maximizing your output.

[@PaulBarger]

I have been told by Signature Solar that if you were using an EG4 battery with communication, this fault would not occur even at a low SOC. I assume you are not using an EG4 battery.

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

[@WillProwse]

Nice!!!!

[@EBKRV412]

@ItsMeGiga that's awesome and exactly what I'm thinking about doing as well. Did you wire the inverter directly to the rigs panel or did you wire up a 30a RV plug from the inverters output to plug the rig into the unit? Do you have a soft start on the AC Unit? Which 60a converter did you use? Have pics posted anywhere? I would love to see 👍

[@ItsMeGiga]

@@EBKRV412 sorry I didn't see this. So I wired the automatic transfer switch directly to the grid Terminals and directly to the panel. So the unit can be powered by shore power or generator. I don't have a soft start on the AC but it's on the todo list.

[@tomproctor.archive]

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.

[@kimmer6]

I am in the middle of building a unit for my 3/4 ton GMC van conversion using stuff left over from other projects. The 300 amp hour Chins lithium battery, Renogy 2000 watt inverter, and 40 amp MPPT solar charge controller fit in a box between the front seats. 2 weeks ago I installed 4 of the 100 watt solar panels on the roof and they are hardly visible. I lucked out and there is no wind noise and I can't tell they are there. The system is 3840 watt hours and has a Renogy bluetooth BT-2 unit and the Renogy shunt type state of charge meter. We use the van for 2-4 day long trips and want to run the smaller Instapot, air fryer, and power up the removable fridge. We usually do trips along the California coast so the temperatures are usually mild. I can run an extension cord and power my garage freezer with the van when I'm not using it. The EG4 is equivalent to 400 amp hours in 12 volt batteries, 5120 watt hours, more power for an AC unit.

[@MatWalter-q3h]

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.

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

[@jeffrodabro]

Finally convinced me. Just purchased the whole system.

[@jeffrodabro]

Got delivery today. Took me a little longer than 10 minutes, but it's up, and charging now. P.S. pay the extra for premium shipping. Although I paid over $300 for economy shipping, it's super economy, no tracking, terrible customer service with the freight guys. I think premium shipping is over $800

Love it! I built a hand-truck power system about 8 years ago (Googlable as the "Shacktopus portable power cart") How far we've come since anemic AGM and complex support circuitry! I think I need to replicate this for my new mobile lab. I appreciate the clarity and scope of your videos... thanks.

I live in South Aftica and I built a similar system using uour videos,Will.....3kW Growatt All-in-1 inverter, 2 x 12V Hubble LiFeSO4, 2 x 440W panels....the system powers my Freezer,Fridge,Washing machine and charges mh electric gate battery. We have a lot of power cuts in Sough Africa, so I really appreciate your help in building this system☘️

[@danielking2944]

Also, I parallel the battery with my home solar storage when I don’t need it. That insures that it stays charged and gives me more capacity at home.

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

[@Alpha-ms9nj]

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.

[@vooduuchild3601]

Got my Delta Pro for $2599 from Costco with 2 accessories as well, the EV plug and remote digital display. For portability, the DP is just less bulky and fits in my RV easy. It does have limitations, but for what I paid, it's great for RVing. Also great to use around my property, even though a little heavy. Love the app too. Integrates all my Ecoflow units so easily. It is definitely a niche unit, but for portable power, it's compact and with Costco much cheaper than 3699

The difference is even smaller after the 30% tax incentive.

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.

A quick update on this unit. I’ve had mine for about a year with mostly pretty good results. I do have a major problem with EG for and their lack of support. I’ve spent hours trying to figure out how to upgrade the firmware or get the Wi-Fi working or get any type of service at all. I don’t think EG4 is a good company to work with. I think the handtruck system concept is good. I would definitely look for another inverter from another company after my year of using this.

I own a Mobile Auto Detail Cleaning business in Alberta Canada. I'm going to buy this system to add extra power to my Van Mounted Steam Cleaning Machine. I might actually buy the 14KW battery instead then I can run my Steam Cleaning Machine out in a farmers field where no on site power is located. With this system I can Serve my Customers Anywhere. Thanks Will

[@frankmurphy5]

The only thing I'd add is a Boston Dynamics robot to wheel it around for you and get behind the fridge to unplug it.

[@CaptBill69]

I think the EG4 3000 ... makes allot of sense for Reputation, and Abilities for the $, including how two or more units can be networked together on same battery bank, including for 240vac split phase out put. I was considering a basic EcoFlow Delta 2 w extra LiFePO4 battery (lesser than one you are comparing to/ as backup power at girlfriend's house) ... Now I am seeing how spending a little more translates into way more abilities and options ... Thanks for this review.

[@johnhufnagel]

I like this. One question though... you mentioned using 2 inverters to make 240V. can it be done with to completely separate cart setups, then join them with minimal cabling to make 240V? my reasoning is... I could see using 1 of these near full time as a solar power station for my business computers, but would love the option of firing up a second cart, making a couple simple connections, and be able to bring the whole house online in an emergency.

[@jayjonah2762]

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!

Outstanding. Could you show how to add a 30 Amp RV receptacle in the schematic? Would I need a sub-panel? That is a significant reason for wanting a larger unit like a Delta Max etc...

[@coachwillits]

Did you build this setup for your RV? This looks like it might be something that would work well with my 22RBE.

[@johntate5284]

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!

[@matthewborne7659]

Will, I'm assuming this could also be done with the EG4 6000XP? Would there be any additional considerations?

[@eliaustin3745]

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

[@sailme2day]

great system build and step by step demonstration Will. The only thing you might add in the next portable build is to mention, a person could wire an RV or whole house 120 volt generator cable to the invertor, and plug the portable unit into the outside or inside generator outlet. :) thanks for your hard work to educate and save your viewers some $$$$$ Could we upgrade for $1300.00 the EG4 6K Off-Grid Split Phase Inverter | 6000EX-48HV to get 240 volt output for running their well pump, all still have all the same great features ?

[@ross2033]

Awesome. I'm wondering the same thing. When plugged into shore power does it auto switch to a "passthrough mode"?

[@stldigitalmemories]

I have a pre-built shed that I am looking to turn into a mini-off-grid shelter. There is enough room for four solar panels. I like the flexibility and expandability of the hand cart. Great video. Anyone should be able to make this. Thanks

[@clarencewiles963]

Thumbs up 👍 thank you for the information.

[@jeffjackson6358]

Definitely a nice system. And good for rolling it around your house. But you aren’t throwing that in your car and taking it camping. EcoFlow is killing it right now.

[@Tumbleweed5150]

I built a similar system, but 24V instead of 48V, into my pickup "camper", which is actually a work-topper, with 750W of solar on the roof. Works great while camping, as well as powering almost any tool I might need to use. Also, I haven't plugged into shore power since testing that function after completing the build.

[@tradermunky1998]

More than 50% more power at less than 2/3rds the price! I love it! Now my friends will think I'm ghetto when I show up at the next outdoor party, but only because they are idiots 😂

[@kylefrandsen2665]

My biggest issue with a 48 volt system for this purpose is that, in my area, it's likely going to be used during a storm-caused outage when no solar is available. I would need to charge it using a car alternator and I don't see a lot of good options for 12v DC --> 48v DC. I do have a car with a 140 amp alternator, so I should safely be able to pull 750+ watts. If I were to go this route, it looks like my best bet would be a 750 watt DC --> AC inverter connected to a 15 amp/48 volt AC-->DC charger. For my needs, I think a 200AH 12 volt battery with the Renogy 50 amp MPPT/DC-->DC charger and a 2,000 watt inverter will run my fridge and a couple lights for almost a day and can be charged from the car in 4 hours or, if solar's available, can probably run indefinitely without the car (or with only an occasional boost). Granted, it's not the power or ease of this setup, but it'll cover my critical emergency needs without the hassles of a gas generator (I have to keep gas in the car and maintain it anyway, so it's not 'extra').

[@mrwess1927]

What you could try is to route an dc generator up to a gravity source and use a solar mppt charge controller going into your battery bank?

[@mrwess1927]

How to pump the electricity into the battery so you can use it later.

[@kylefrandsen2665]

@@mrwess1927 This is just an emergency backup, so I don't want to get overly complex. After reading up on the EG4, it looks like I can limit the battery charge rate in the settings. If I set the charge rate to 10 amps/48 volts, I would use a small inverter attached to my car to pull 40-50 amps/12 volt from a 140 amp alternator. Unfortunately the charge rate setting is in 10 amp increments so I couldn't set it to 15 amps. I could set it to 20, but I don't know how comfortable I would be pulling 80-90 amps off the 140 amp alternator for hours at idle. It's not the greatest solution to charge a fully depleted battery, but I wouldn't use the full battery capacity just running my fridge, a couple lights and charging phones/laptops. I could run the car a few hours in the morning and a few hours at night and probably last a couple weeks on a full tank of gas - at least long enough for the sun to come out or for the grid to be repaired.

[@paulhenry8174]

Perfect build

[@tomproctor.archive]

They provide a Nader breaker for use inline between the positive battery and inverter. I also recommend using a DC beaker for your PV in, so you can safely shut off power to the inverter.

[@whitefreeman5798]

as someone that ownes an eco flow delta pro i can say that this system provides much more solar which is a very weak point in the eco flow

[@ItsEverythingElse]

The Ecoflow takes 1600W of solar which is still a lot. If you need more than that then yeah, the Ecoflow is not the right unit.

[@k5edd128]

Smiling! Just ordered one to run my amateur radio aka ham radio station. Will use it to power all the 13.8-volt power supply's that run the radio, each radio at 13.8 volts will pull 23 amps DC. Never run more than two at a time and that power consumption is only on transmit. I think it will run all my computers and ham radio stuff off the inverter and 48-volt battery. That will be like running on a UPS all the time and not having to worry about power outages, we get a lot of short 10 seconds outages and that is very hard on the radio and computers. Most new ham radio equipment is more computer now days. Would liked to have had two inverters and batteries but the old ham radio budget pretty much got spent on just this. That new one that does split phase would have been nice too EG4 6000XP. 73 K5EDD, celebrating 50 years of ham radio fun.

[@edolson1698]

What's the idle consumption, that's always the bummer.

[@Tumbleweed5150]

I can't seem to find that information on any of these all in one unit's user manuals. I so rarely have mine at an idle, it's hard for me to test for that.
