One thing I like about your videos is that I can understand what you’re saying, both logically and audibly. You speak English, you enunciate, and you don’t play annoying background music or sound effects. I have auditory processing issues, and there are many videos that I don’t even try to watch, because I won’t understand half of what they say, and if there is closed captioning, it’s usually more annoying than helpful. So thank you for being user-friendly (in addition to being very helpful).

Hello Will, I was an electronics geek as a child (before the advent of the transistor) and have worked with electricity at hobby level all my life. Then I got back to rving about 14 yrs ago and it was time to learn all the stuff I didn't know before. To that end RU-vid and particularly YOU HAVE been an invaluable asset. THANK YOU. My only constructive comment today. LEAVE A FEW SECONDS AT THE END OF YOUR VIDEOS. I NEVER MAKE IT TI THE LIKE BUTTON IN TIME, BY THE TIME I REALIZE YOU ARE ENDING. Give an old guy a chance to push the appreciation button.!!!

Loved it. I really appreciate the "proof of concept" . Personally, for me, I learn by seeing then doing. To see the concept striped of complications (albeit important and will be added) just helps me when I'm layering learning. Everyone has their own way of being taught, and you're way, works for me - so thank you. I realize there endless complications and theories we should all know and understand but seeing "level one" applied - so helpful.

Thank you, Will. Only recommendation here for some of the new to projects like this; if that is fine stranded wire you are using, you really should use some sort of mechanical bundling, like a ferrule before landing in the panel. THHN isn't fine strand and is ok'd by NEC to land in a panel like that. The fine copper wire is recommended it be mechanically bundled (or whatever their terminology is) so it doesn't deflect out from under the terminal screw when tightened down. For anyone that might read this as advice. Please do NOT use solder to tin the fine stranded wires before landing in a panel like this. It MUST be mechanical for you safety. If you solder the leads to bundle, the slightest bit of heat on the terminals will soften the solder causing the connection to loosen, causing more heat, which losses more....etc. Just trying to look out for us DYI crowd out there. Not trying to start a debate of any sorts.

you make this so easy for us, thanks for all you do for the DIY community

I’ve been doing this for years. My breakers system has the ability to power my whole toyhauler conversion by plugging it into a solar generator or my Honda gas generator with unplugging and plugging in as needed. I still have to start the gas generator but it is a one pull. Glad you showed people how to do this. Grounding is important.

Will, first off thank you for all the content. You have legitimately changed my life lol. I'm so obsessed with this stuff now all because of your videos planting that seed! I have a Bluetti AC300 with 2 B300 batteries. I have a Reliance 10 circuit transfer switch tied into my 200amp main. We have a small house and I'm not worried about split phase, so the one AC300 setup is perfect for me! I have 1600w of solar via (8) 200w Rich Solar rigid panels. This is where I'm stuck. I have the EG4 Ground Mounts out in my backyard. I got two of them, each to hold (4) of the 200w panels. I have two 16a dc circuit breakers I'm going to put inline from panel array to the Bluetti. I am absolutely stuck on how to properly ground the solar arrays. I know I'm probably over thinking it and it's not a huge deal, but I want it to be safe and done correct. The panels are about 50 feet from the house. I have PV wire (direct burial kind) to go from panels to breakers to bluetti. I'm going to run them in conduit underground just for extra protection. I have two ground rods out back by the panels. I do not know how to properly ground this. Being that the AC300 is feeding a transfer switch, I'm assuming the panel grounding system needs to be bonded with my main ground system. To do this, do I just run a copper wire in the conduit with the PV wire up to the house? I think once I come into the house with the PV wires that they need to be in metal conduit since it's DC. Can I bond a copper wire coming from the ground rod at the panel array thru the conduit into the recepticle for the transfer switch? Would this bond my solar array to my houses main ground system? I'm really hoping to hear back from you, as several "pros" keep giving me conflicting advice and I am feeling defeated that the easiest part of the system is taking me the longest to figure out. Anything helps. Thanks again for all that you do and I hope you are doing well!!!

Great video, as always! For those confused about the bonding...make sure that you test that you actually have a ground-neutral bond somewhere in your system... Don't assume that the Generator already has a GN bond. I believe the AC300 is floating so you'll need a bonding plug in the configuration show here.

OMG I love you! I just spent 6 hours trying to find out how to do that and I got nowhere! Was feeling so defeated! Should have come here sooner!

Straight forward and simple. Exactly what I've been looking for. Thank you Will!

Of course we like it. Great to be able to share with friends asking this very question.

You are my go-to-guy for solar info. Another good video. Thanks

I always love your tutorials. Thanks for reawakening my love of science.

It's good to stick to the 80% rule for continuous loads. If the circuit is rated for 30 amps, you shouldn't exceed 24 amps.

I think I just found my new favorite YT channel!

Nice video Will! I would like to see a video showing how to run Solar PV wires "to code" from the panels say on a shed or roof into the house through conduit. Basically a start to finish solar PV wire video. From the panels to some kind of weather proof connection box, then buried and run to the house, then up through a LB and into the house to the charge controller. Thanks!

Hi Will..Thanks for all your helpful videos. I’ve been racking my brain to figure out how to run my Northstar TC650 pop up slide in camper (with 650w AC) boon docking. Because of your video, I think I will just buy the Eco Flow Delta Pro and plug my 30a shore power plug directly into it. I will create enough solar on the roof to recharge and also have alternator recharge capability. I will also bring my Honda 2000i with me to make sure I can always keep the system charged up. Very helpful. Thanks👍🏻🤠

Good stuff I got the BLUETTI 200 max based on your review love it 😊

You touched on exactly where I am with my strategy

That's a really cool setup! Even if you have a large battery, you could add an inverter with that 30A plug and do the same thing.

Will. Love your videos. I tend to overthink situations till I’m almost mental “lock” and can’t decide on what to do. I’m buying a shed that’s 16x40. It’s mainly being used for storage. I will be modifying one end to be my office/escape from the family room- kidding (not kidding). I’m fairly knowledgeable about most things electrical- and I have the ability to research if need be. The power needed will be enough to run lights (led) and a few outlets in the main garage portion of it and enough for the office. I will be using a laptop, extra monitor, printer, lights, as well as have a few outlets in there as well. Will have a small window unit for AC. I’m still undecided for heat. It will be occupied mostly during the day and evenings- maybe 3-4 times a week. Initially I thought about using EG4 batteries with an eg4 3kw off grid inverter. But these solar generators (ecoflow and bluetti, etc). Which way would you go? Both have pros and cons. The office part is not big- 16x10. Also- I live in FL (Pensacola) which sees about 3 seasons. It can get in the teens a few weeks a year- but is mostly in mild temps. Also it will have solar only. Maybe a small generator if needed but plan on being strictly solar powered. I’m undecided about heat. I’ve thought small wood stove to oil filled radiators.

As always, great information, keep it up. thank you

Thank you Will when I mate you I was blank now I can do a lot. When I finally learn how to edit videos I will be posting as well

Simply. Looks like it works. Thanks for sharing

Great short and to the point tutorial! I was considering doing something similar with my Bluetti EB150, but two things stopped me. The first is a lack of 8 amp circuit breakers (maybe someone makes one, but didn't find it at Home Depot). The second was the EB150 doesn't have a battery heater, and at 45 degrees or lower, I notice a reduced capacity, and an inability to charge (due to the built in thermal protection circuitry). Here's what I'm going to do for my off-grid application, which may work for some who do not already have a Bluetti or similar solar generator. Will has already done a video including every component I'll have in my system (except for the gel battery IIRC), so there's nothing new or scary here for one of his followers. My end state system will be a 200AH Renogy Gel battery (much cheaper per WH than a heated Lithium, and can be charged at 5F), a Renogy 3,000 watt pure sine inverter, a Rover Elite 20a MPPT charge controller, and two cheesy Harbor Freight 100 watt solar panels (which pump out every watt they advertise). I'll do a marine battery disconnect switch from battery to inverter, and a disconnect switch between the solar panels and charge controller. I'll put an inline fuse between charge controller and battery just for an abundance of caution. The inverter has a high current AC output, so the load center will attach to that, and the inverter will grounded to the metal structure of my shipping container shop/storage building, which in turn will be earth grounded to an 8' ground rod. In this situation, the neutrals will not be attached to the grounds since my small load center will be acting as a sub panel. I'll run the inverter's remote on/off connection to a standard residential wall switch mounted near the doors of my shipping container, as well as the switch for the AC lighting. The load center will use GFCI breakers for all outlets, and a standard breaker for lighting, even though GFCI breakers are much more expensive than GFCI outlets (just because it makes me feel safer). The load center will be the same $30 6 position sub-panel Will used here, with only one bus bar connected. One breaker for lighting, and one each breaker for the indoor and exterior outlet strings. This may or may not work for anyone else, but is fine for my usage patterns. I figure I'll use lighting two or three times during the week for 2 hours or so, and maybe 4-6 hours on the weekends at 250 watts/hr, so my measly 200 watts of solar panels will certainly keep the battery charged when I'm not at my remote site. My big load would be using a 1400 watt air compressor (maybe 30 minutes of run time per day), or my wire feed welder (again, probably a max of 30 minutes run time in any day). Beyond that, I'll routinely run a laptop, and my internet hotspot. This system does have room to grow, as I can slap a second battery in series and add two more solar panels if I find myself coming up a little short in the future.

This would be perfect for my Skoolie. Thanks!

Rather than buying a cord and cutting it, a better solution is to have a permanent 30A outlet mounted to your breaker box (30A breaker) with a mandatory main breaker switch shutoff protection bar installed. This is how my generator is set up for my home. I plug it in when I need it and put the generator away if not being used.

Be great to see you do a V2H ( Vehicle 2Home) thru your solar inverter 👍 I use my mitsi PHEV outlander to power my off grid caravan, using the mitsi CHAdeMO ( CHAdeMO is bi directional as standard) plug connection thru a 4 KW solar charger, the 12 kWh mitsi battery lasts all weekend off grid 😎👍

Good idea , and very well explained and demonstrated !!

Hi Will! Thank for the information! On the other hand I was hurt every time the metal box was scratching the AC300's front... Auch...

This should be sponsored by Milwaukee, good choice, Will.

I love your videos. I already know how to do this kind of thing, but I still love watching you do it. That's how I know it's good 😁

I installed a jumper wire inside the bow to use both poles (you don't recommend). My 3000 watt inverter is inches away from the sub, I used 8 ga wire from the inverter to the sub and for the jumper. Only using 12ga romex, 15a fuses, powering 4 freezers, and 2 refrigerators for over a year with zero issues, no noticeable hot spots, warm breakers, wires etc.

Love your videos, would really like to see an investigation into Nickel Iron batteries used with new generation solar cells, charge controllers, and inverters.

I like how Will keeps the bits of video where he make comments to himself.

Thank you so much for this video! i look forward to the next video :)

Showing how to do this with an interlock kit would be cool

Just what I needed. Thanks 👍

There are generator outlet boxes that are designed to work with common generator extension cords such as the one shown in this video. That might make for a more code compliant installation.

That's cool brother thank you for sharing this five stars

Just a little additional comment: with a full size house breaker panel, one can add a 30 Amp double pole circuit breaker with its two inputs connected to each other and fed from the generator. This would apply the 120-volt generator source to both sides (legs) of the house breaker panel.

Next time you can make live cable shortest, neutral longer and earth the longest :) helps when cable which is not permanently in the wall get pulled by unfortunate accident.

Thank you!

Good to see more vids other than server rack systems ;)

good stuff, thanks!

Outstanding info....WP. 👊

240vac at 13 amp (max per socket) is our domestic power in the UK and we don't use cables or plugs that size. 2.5mm² is the nominal ring main cable size, twin flat and earth. Obviously external cables would have to be rated accordingly.

Another great video Will. Been subscribed for a while and now I am ready to dive in to the solar world, thanks to you. That means I am extremely new to solar. I am starting with a small project in my chicken coop. In the winter I will be running a small 12v pump (0.7 amp) and 1000 watt (8.3 amp) heater for the water system. Other than that, I may set up a small radiant heater for the extremely cold nights and some LED lights on motion detectors to help keep unwanted critters away. Can someone let me know if the water heater is too much for a small solar system?

Good one!

Good info for people. I’m being lazy and just going straight from my fifth wheel into the ac 500 but when you do that you have to remember to turn off your house inverter so you don’t charge your house batteries. You’re also practicing to be a parent do as I say not as I do. Lol.

Wishing you would do a review of "the bank" from Univix Solar Generator - comparing to a smaller generator like this Bluetti or ecoflow - but better yet compared to your DIY 48V system using eg batteries and all-in-one inverter?? Thanks for all your videos - super informative!!!!!!!!!

OMG thank you!!! I need this 👍👍

I wish you would show us how to do the same from an eg4 48v-3000EHV inverter

Would this work with a gas generator as well??

HOWdy W-P, Thanks for the Tutorial The WiSeNhEiMeR from Richmond, INDIANA COOP ...

That seems really funky that you have the panel with openings for the other bus. What would be the parts that fill in that part in a more permanent installation?

Awesome

Will not receiving notifications and I am scribed and all notifications marked so in the last month have only received one notification on a timely manner. I went to your channel to find this one.

Hi Will. Love your channel. Could you possibly do a review on Zendure SuperBase V ? Never heard of it before. They say they have a better than Lifepo battery.

Good information, I have a small cabin that has a well pump that runs 240v at 5amps, it only runs for 1 to 3 minutes depending on water consumption, would a step-up transformer work 120 to 240? Thank you

You're a dang GENIUS, you finally did something this OLD head can do LOL, if you did the optional hook up you were talking about would be good also and GIVE the pros & cons of both types of hookups, I assume that all then that's needed is to plug in the panels

Have you ever talked about the tax credit and what is allowed ? Do you have to have a whole house system or a battery back up system to run a couple devices to qualify ?

I love batteries

UGH…. I have a breaker box where the ground and neutral are together (one bar). Do I need to separate them in order to wire up my box like this to keep from burning up the battery bank?? Thanx in advance

If you already have a generator hookup for your main panel can you just plug the solar generator into that?

What about to distribute to a 12v breaker

Will, what's the best way to connecta 30amp RV plug to the 20amp receptacle on the original AC200?

Can you do this for power stations without a 30amp plug/ Can i utilize a 20amp plug using the same method?

Can I connect then bluetti directly to my Rv 30amp power connector?

Please please make a video about 48v lithium titanate battery system with 48 volt solar panel..It will be very much helpful for everyone....🙂

Will the panel need a ground rod if installed in a cabin?

Can u show how to do this with Ep500 im not to certain on what plug and cord to use

Good practice for power circuit calculations is not to exceed 80% of max rating. i.e. (30amp x .8 = 24amp) max. amp output. or 110V x 24A = 2640W

Can you mix 2 different brand of solar panels??? Like harbor freight with renogy???

Hey Will, thanks for all the information you put into this video. I had one question, inside your panel, you kept the ground and neutral on separate bus bars because it was a sub panel. Did you have to run a ground wire from a ground rod up into the box to the ground bus bar?

Bluetti ac200max , ac300 and ac500 power stations have a floating neutral so wouldn’t you use a main panel with bonding screw connecting the grounds and neutral buss bars ?

have u seen this setup yet Gendome 3000 Portable Power Station

What if you want to be able to switch between battery and external power such as at a campground? Transfer switch? Sounds like another video :) And... when on external power it should recharge the battery! You should get an actual RV, there are so many cool videos you could do around off-grid power for it.

Hi, I have two Delta Pro with the 240 Volt Hub tied to my power circuit Box with a inter-lock in-place and off Grid. Now when I run the Eco-flow Delta Pro with 240 volts and grounded to through to power circuit Box. Now my question is I have 8 200 watts on each of of the 2 Eco-flow Delta Pro Generators for a total of 3200 Watts, Do I need to ground my Solar Panels as well?

Can you use the NEMA 14-50 from the AC500 to the sub-panel and just run 120v but get full 50A I presume?

Ok here’s a good one for ya… if my house has a 50A inlet, can you use the 30A solar genny and connect to it using a dog bone adapter?

If we added an additional cable coming from an additional equally sized/power generator to the second bus bar in the panel would we achieve usable 240 volts. Thank you.

Hi William; Thank you for all you do. We out there appreciate it. What is the best way to communicate with you to ask you a question. I bought an Apex Pwr station by INERGY 2 yrs back before i started watching your channel sadly. It's very limited as you pointed in your video review. however, much of you commented was above my head. so, I bought your book (mobile solar pwr) and watched more of your videos. I need help adding batteries to the system. INERGY says i must buy batteries from them at $900 a piece (new Flex batteries). there must be a more cost-effective answer. please help.

@WillProwse I want to remove those silly rubber outlet covers too. Did you just cut/tear them, disassemble the unit, or some other technique?

Have you done a Voltserver yet?

What about a diy solar generator. How would you install a 30 amp outlet on a diy solar generator?

I have a couple of fairly technical questions: 1) Is the cable/connector 30A rating limited by current density in the contacts or wire? Or is it limited by the series resistance of the long cable, which causes voltage drop? The reason I ask is that the cable will usually be cut pretty short for this type of installation. So if it’s the resistance, then cutting it short makes it better. 2) The AC300 output is rated for 3000W/25A continuous, but it is also rated for 6000W/50A short-duration peaks, which is useful when starting some loads. By using the 30A fuse in the load-box, are you negating that benefit? After all, the AC300 output is already protected, and each load from the load-box has its individual circuit breaker already. I appreciate redundant protection, but it also comes at a cost of additional resistance and additional points of failure. In this particular situation, I’m not sure it is warranted. 3) Not an additional question, but some sharing - I did something similar as a partial “at will” off-grid system in my house using the AC300 and the Reliance Controls Pro/Tran2 manual transfer switch. It patches in to your existing circuit breaker panel and enables 10 circuits to be individually switched between grid power and AC300 output power. In case I am not home during a power outage, I keep my refrigerators and WiFi network continuously on the UPS system of the AC300 output. Then I have 8 additional 110V circuits in my home that I can switch over manually as needed in the event of a power outage. Also, as I add solar to this system, I can put more and more of my circuits on the AC300 to balance my daily loading with my solar production and my UPS needs. The AC300 configuration settings are good for that. I did all of my own installation. My circuit breaker box was very crowded, so I used Wago connectors instead of wire nuts so it would all fit. The Reliance transfer switch needs a lot of connections inside your circuit breaker box. Fortunately, the Reliance box is pre-wired within itself. Of course now I wish I had the AC500 or even one of the server rack systems. But I think this will serve my needs. I suffer from a lot of partial shading at my house due to tall trees here in the Santa Cruz mountains. So I’m not thinking I can make enough Solar to be completely off grid. Anyway, thanks for your videos educating us all.

Hey Will, have you heard of Mango E power supplies? I don't have any experience with them but they look pretty good on paper. Might be worth a review.

So is the benefit for this that your outlets can be further apart than just the bluetti and being able to run a string of lights or something?

I have a Question for you Will. I have a cabin in the desert I use in the winter. If I switch to LFP batteries should I leave them hooked up in the summer? The building goes to 150° f sometimes. Or should I disconnect the LFP batteries from the solar system and turn it off. Right now it's an FLA system .

I have the delta 2 that doesn't have the 30 amp outlet. Is this same concept workable using one of the 120v outlets and I'd just have less power to my sub panel?

Thanks for this. I have my AC300 and 2 B300s and want to put them in my van. I understand I should plug the AC300 into shore power and then to the distribution panel and the Bluetti will decide whether to power the van with the battery or shore power when available via the UPS. Is that correct? If so, do I need to use 30A shore power service or 15A (which was the default setting on the Bluetti). If I use 15A will the AC300 be able to pass through the power at 30A? (I realize this probably confirms my lack of knowledge regarding power. I always said there are no stupid questions...just stupid people who ask questions!)

What is your opinion on the Renogy 320v panel? I want to connect 2 panels to my Pecron E2000LFP. If not what would you recommend? Just found your channel. You are very knowledgeable on anything electrical.

Ive watched this 36 times

Hi Will, I have 7. 20 amp breakers in my home. If I hook up all of them and my load is moor then the 30 amps on my Bluetti will it shut down the Bluetti burn it up. or shut the house down. Because I seen you do only one breaker at 30 amps. I hope you understand what I am asking.

Question about the no charging a Tesla , doesn’t work direct from the Ecoflow delta pro cuz of floating ground but what if you’re energizing a home electrical panel which does have an earth ground and you have the charger wired into your panel? It should work?

Please share what is the name of the strip tool the blue handle and the model thanks

Hey, your videos are great inspiration, any way you would consider helping me with my solar requirements to power my small inverter that I managed to put together with your help through this channel. We live in SOuth African where our power grid is on the verge of collapse and as a digital creator, it impacts on my ability to provide a conservative living life style. I hope you can help, I love and follow your channel, you seem like an incredible guy with a passion for the trade, Keep up the amazing work.

Question: my camper lifepo4 battery bank is charged by 800 watts through a victron mppt controller. Can I also use my renogy 200 watt portable “suitcase” panels with its own pwm controller on the same battery bank running both controllers through the distribution box ( wired parallel)? I can’t find any videos on this subject.
