Keep the Power On During an Outage?! Install a Power Station Transfer Switch! 

Dang Jason, you really thought this through. I like the flexibility that you built in to your electrical panel setup. I also like that you can easily swap out for future power station acquisitions, as technology improves or the current solar generators wear out. Very nice

Thank you for the inspiration! Just picked up our transfer switch using your link as a thanks. We have an AC300 with an extra b300 and an AC 200p that we have been using via power cords. While it works fairly well, we definitely were not using our set up to the fullest. This is an awesome solution. We initially wanted to use the Bluetti sub panel but this gets us started without spending another $1500.

You have some of the most direct, non-cryptic content I've seen. I'll share your page.

I installed the same one you have shown here. It was used by Nature Generator Elite system that I have in the back of our house. We have gone through several SCE power outage days since last year. This works out very well.

I did a similar setup last November with the AC200P and 2 B230 expansion batteries. At the time I was having solar panels installed on my roof so I had the installers add 2 additional panels to the array but not tied into it. They are run along the same route for the main array but hook into my Bluetti. The two panels are 405 watt each. The AC200P can only accept up 2 700 watts but I frequently show 725 watts going in. In order to get more out of the system than just emergency power I charge the batteries during the day and run of them at night after I get home from work during the week. On the weekends I run off of the batteries during the afternoon and as long as I have good sun my solar panels easily keep up with my power needs further cutting down my electrical consumption from the power company.

Having the ProTran 10 breaker unit installed tomorrow. I have2 AC200Max’s and an AC500 with extra battery on order. Can’t wait to get this thing working.

BOOM! This is what im talking about! Game changer on every level.....Thank you for sharing

Wow, that that is a smart and easy set up. Will recommend to a few people looking to do this very thing.

I got a 50 amp transfer switch for our Jackery setup. Explorer 2000 Plus x 2 + 8 kWh total charge capacity with LiPo4 batteries. 6000 watts. Jackery is doing it best right now.

Great video. Learned more the 2nd time I saw it . I’m trying to do a similar setup.

Awesome set up! This is my exact goal for my house as well.

What a timely video... just bought a transfer switch, just need to install it.

Nice set up. I'm building a house and just purchased the Bluetti AC500 with 2 batteries, and 420 watts of solar. Not much solar but enough to get me started and these are the portable panels so I can take all this with me in my 5th wheel. I'm going to have the electrician wire the house for generator backup (I did this myself on our last house using the same transfer switch you used), but have the generator plugged into the Bluetti AC500, along with plugging the solar into the Bluetti. I'm also on a grid, so I may have a plug in from the AC power to the Bluetti so I can charge it if the Solar can't keep up, basically using the AC500 as a UPS. I'm looking to put all of my house on the transfer switch through the Bluetti, and when I get more solar panels I'm hoping I'll be able to keep my grid power bill to a bare minimum = powering my well pump, and woodworking shop (220 outlets). Maybe if this all works well I'll get a second AC500 and get 220 working but that's for a later date.

Nice setup. I just got Tesla solar installed grid-tide obviously, and have built an offgrid backup battery solar array. No transfer switch yet for the offgrid setup so have been using extension cords for the loads in my basement. If the power goes out here, I’m primarily concerned about the fridges so the setup might be enough, but if I get an EV and scale the battery, I’ll likely go a similar route. Thanks!

fantastic. real life application,,,just what we need as an example. Tks Jasonoid

Exactly what I plan on doing later this year! Great timing Jason!

I have a Bluetti AC200P, EB150, EB55, and AC50S that I purchased to power various items in the house in case of power outage. Then about 9 months ago, I became aware of these transfer switches. Wow, one box to power everything that I need to run with just 1 solar generator. I plan to install a 6 circuit one this summer. As I would hook up the AC200P to this, the only need I would have for the other solar generators is as back up batteries to recharge the AC200P. Can't count on solar input when the weather is bad, which is what likely knocked out power around here.

GREAT JOB JASON

Great explanation and great tips, thanks 😊

Great video! I have a very similar setup. I used a Reliance 10 circuit transfer switch and I also installed a 30amp inlet near my ac300 that goes to a 30amp breaker in my main panel that is controlled with a safety interlock. That way if there is some other circuits in the house that i need to power during an outage I can easily switch from using the transfer switch to plugging into the 30 amp inlet and flipping the interlock. Another benefit is I could use my gas generator by running my 50 foot cable from my generator, through a small basement window and plug that into the inlet.

Great video! I was just thinking about this myself.

Brilliant! Love watching this stuff, but I rent so I'll be thinking about how I can do this. I have used a grid tie inverter (cue all the warnings and negative comments) that has worked extremely well, so that's something I may try again. Well done Jason! Jim

Great Info. Thank you!

Thanks you made it so simple.

Very Interesting Video! I have a very similar setup for my Bluetti AC200Max w/ extra B300 battery. During my research I never found this Huntkey transfer switch. I'm 100% positive that it is made in USA by Reliance Controls, but not one that they show on their website. I purchased the Reliance 306A which is designed for a generators using 30 Amp L14--30 four wire plug. It's designed for a generator with 240V capability that obviously doesn't work for 120V invertor. I ended up purchasing a short adaptor cable to plug into Bluetti 30 Amp RV outlet that connects both the hot conductors of the L14-30 and am using a 10 ft. L14-40 cord. It functions the same, but was extra work and bit of extra cost. I wish I found this switch first. Thanks for sharing this with others. Huntkey/Nature General must have seen this market need and worked with Reliance Controls to create a different model for inverter applications.

Good info and set up bro

exactly what I'd looking for. Thanks

I use nearly this same setup for TOU (Time Of Use) Billing from my electric company. For 4 hours of the day they raise the rates 5X base rate so I run off battery!

Very helpful thx.

This is exactly what we need Thank You 😎👍🏼

Nice set up. Yours is the first video I've seen, showing how to fully use the power of a Power Station, to power your house. We have a similar set up, but with the Reliance six and ten circuit Transfer Switch. I installed two inlets outside, to connect our Tri-fuel generator to. (It runs off our homes NG line) Each transfer switch has an inlet, like yours, for our Power Station. I use a changeover switch that's connected to each inlet, to switch between two power sources. (Generator and Power Station.) So, we can have two power sources coming in, but only one power source is powering the circuits in the Transfer Switch. You forgot to show how the UPS function works with this set up. We have the Ecoflow Delta Pro which uses an EPS (Emergency Power Supply). While the DP is plugged into a wall outlet, it can pass the Utility power through to whatever is connected to it. (Without using the invertor or battery) When the power goes out, the DP switches over to battery power in 30ms. Meaning no power loss.

That is awesome! Nice setup.

Really like your setup. I have an AC200MAX with two 230 batteries. I already have a 220V transfer switch installed for my 7,500k generator. I was thinking of wiring an adapter to supply both legs so I can select which circuits want to energize. I would make sure to keep all 220 breakers off when using this setup.

i just got my transfer switch installed finally no more extention cords all over the place. powering almost everything in my house. I have 3 batteries connected to my Ac300. saving up for a 4th.

I hooked one up five years ago when I built my house. I’ve got the bluetti ep 500 plugged in, and ac200p for backup

My man, happy you made this video!!

Genius. I wish I could do this.

That is so smart!

I installed the same transfer switch for a gas generator. But now seeing I can get an AC300 and solar and use the transfer switch daily like you. And if I run out of battery power can easily plug the gas generator back into the transfer switch. Or use the gas generator to recharge the AC300 during the day and use the AC300 at night and not disturb the neighbors with a noisy gas generator or call attention to myself. Thanks for the simple walkthrough!

Love the setup and thank you for the video. What solar panels are you using outside?

I would be grateful to have that setup.I have 3 power devices, largest is 1800-2000. Need a AC200 or 300 to power my freezers and fridge.

Hey can show/ explain the solar panels ground is connected ?

Thanks Jason for all your answers. I am new to the concept of backing up some of my home electrical systems especially my furnace. How is the Bluetti EP500 Pro with a built in UPS compare. I assume I still need a separate electrical panel to integrate to my home electrical system or just a dedicated breaker....thanks

Great video Jason, I'm going to be doing the same thing this summer. I've got a Delta Max on the way that I will be using. I also have about 15KW hours worth of batteries that I'm building to keep it charged.

For most panel you can get a lock out it means that to turn on your auxiliary power supply the main power switch must be off the unit can then be slid past the main shutoff switch locking it off as long as the auxiliary power switch is turned on likewise as long as the main breaker is on the auxiliary power switch cannot be turned on the advantage of this unit is all circuits are available so if you have the watts to run the load you can use the item maybe can't run everything at once but shutting off the fridge freezer or furnace for an hour won't cause a problem for a 120 volt unt it means that both legs of the panel box are on the same 120 leg same as when your electricity provider put a limiter on inplace of your meter except their's limits you to enough power to run any furnace so for those with natural gas it'll usually run a 100 watt incandescent light before tripping off I'll be putting one on my auxiliary panel box and since neither my store or dryer plug is in use I'll use one of them I want to see if my 2000 watt solar generator will not run my house if it will I'll cut the grid till December and then cut it off again at the end of January will save me 1200dollars plus energy usage around 2000 dollars or more and keep my line in

Great videos Jason and rich with important facts and experience. Awesome work and thanks for sharing. I am also building a solution for the backup power but I have a twist that I would love to include in the setup. I was going to repeat your setup with a manual transfer switch powered by the Bluetti (type to be determined) and that Bluetti recharged by gas genset and solar. The twist I'm trying to work out if possible is if I can automate the use of the Bluetti during high peak hours and then switch back to grid without any manuel touch from me? I don't seem to be able to find automatic transfer switches with timers or other controls to allow this. Any ideas or should I be looking for something different? Many thanks for any suggestions

My electrician just added some solar 50amp breakers to my main panel and a flip switch to turn off the grid power and flip on the Solar Power. It was a simple hook up and I didn’t have to have a separate panel. This way I can choose which breakers to use, without having any limitation’s on the whole house. Very inexpensive!

Working on mine

I have (4) 1408Wh power stations (110V 15A). Each can connect to a backup battery, but I just connect a pair of power stations together using the cp3500 cable. That will give me 2 pairs each with 2816Wh. In each pair, both power stations can be charged individually at the same time, and have power pulled from both while having one of them connected to the L14-30 generator inlet box using a specially wired adapter. I power both legs of the panel at the same time (240V breakers are off) from one pair of power stations. The other pair is a backup. I was thinking of building a "Y connector" and connect each pair to a leg in the panel. The ground and neutral are bonded in the main panel and I have the interlock kit.

Awesome!

Hey great video man👍🏼👍🏼. quick question: if that and L14-30 that is plugged into the transfer box? What receptacle is used on the end that plugs into the transfer switch? Thanks 🙏🏻.

love you hook up I am installing a transfer switch as well 306a1-eco pairing it with a single delta pro 120v using RV plug to transfer switch. can i use another pro to use as power to plug in the main unit into it or will that cause a any fault

Hey Jason thanks for the great info. Could you tell me (a) if there's a preferred way to bring the PV cable into the house (through a basement wall) and (b) if you need a disconnect switch between the panels and the bluetti?

I tested out the OhNoNo cord on my channel on a single circuit. I know if the AC200p detects a live circuit it won't work. I can't say there isn't some bleed on the neutral like you were worried about because I didn't do that much testing.

great idea... how was getting the permits to install it? wondering if something like that would help with my RV

Will not just use a generator inlet VS the transfer switch?

Great Video Jason! I'm subscribed to and enjoy your channel. I'm a newbie to solar generators and solar charging in general so forgive me if I mess up some of the terminologies. I just purchased a Bluetti AC300 w/two B300's and plan on installing a transfer switch after seeing your video but have heard other people having an issue with the floating neutral and pass-through charging. They're saying the AC300 could be damaged while pass through charging if you don't get the right transfer switch that addresses the floating ground or neutral. A few of the recommended transfer switches were the Bluetti Smart Home Panel the Reliance X-Series neutral switching panels and the Generac transfer switch. My question are these nessasary because I see in your video you're doing pass-through charging with you Pro-Tran transfer switch, have you had any issues yet??? Thanks and keep up the interesting & informative videos!Rick

@jasonoid are you able to keep the AC charging cable plugged into the wall as a backup for the AC300 if your solar intake lowers and the battery depletes? I realize you can just flip the transfer switch from GEN to LINE but it would be nice not to have to do that and the AC300 recharges from wall automatically if it reaches 20% battery level or something like that.

Have just hooked up one in my house, with solar panels connected. Recently, we went on a trip, and street power went off. Battery power kicked on, ran my fridge and freezer, sooar charged the battery. When we cam home, all was well, didnt even have to set clocks as the were apart of circuit connected. Well, exept for the stove, as thats 220 volts. 😅

The advantage of this setup is that you can run an inverter generator in short intervals to recharge your battery banks, yet the house can enjoy 24x7 coverage. I say inverter because I wouldn’t want to damage the battery banks. People waste a lot of fuel running generators constantly when the needs of the house are low or changing throughout the day. I see a generator (especially nice if you set it up for propane or natural gas) still having a role for the occasional recharging, but the battery banks are a super way to feed essential systems. If the batteries fail, then just pass the generator directly to the transfer switch.

I have the same transfer switch. Do you flip the switch from Gen to Line daily? If so do you think that will wear out the switches sooner?

Jason, can you do this to a old house with the old fashion screw-in fuse panel, or do you need to upgrade the home panel to a circuit breaker type?

Lol @ my wife is kinda sick of that. Hilarious. Mine is just sick of the stuff turning off

Hi, I like your video. Just asking. With your setup, do you sell solar to you utility? Can this setup sell solar to your utility? Thanks.

do you know of a video showing how to wire in that transfer switch box?

It sounds like your objectives are similar to mine. I wanted a backup power source for the critical stuff. Like you, I want to run my refrigerators and freezer on it full time. The reduction in the power bill will partially help pay for the system. I also have the AC300. I have 4 batteries. I have the system in the basement so it will have a steady temperature even if the air conditioning isn't running. My main power panel is nearby. I was under the impression that the Bluetti can't have neutral wire grounded as it is in the main power panel. Does your transfer switch also switch the neutral?

Any recommendations on a good place to buy 200-300 watt panels for a yard mount that will be tied in to a Bluetti 300AC?

Looks like a nice canned food storage shelf. In the video when you switched to basement to shore power the lights actually got brighter. Was that real or a play with the camera white balance due to the flicker?

what would you consider the minimum size battery backup to make a transfer switch installation worth doing?

Thanks for the video. I bought this transfer switch for my Bluetti 300 set up. Do I need to buy any other cables before the electrician comes to install it? Or does it come with everything I need? Thanks so much.

I couldnt tell from your explanation, but can you have some circuits on solar and some on grid at the same time, or is it one or the other?

Yippee! New subscriber here. Loved the video. I have 2 AC300 & 2 B300s. Looking to buy a 10 circuit transfer switch because I have 2 full sized Fridges & 2 full sized Freezers. (outdoor Kitchen gets 100° F tempts. during I plan on buying the Ford Lightning with extended battery. The 80 amp charger that comes with it (called Charge Station Pro) requires a 100 amp breaker. My AC300 is limited to 30 amps. Does this mean I will NOT be able to connect my AC300 to charge my EV?

Great video. Question: How can the manual transfer switch be automated, meaning I dont have to switch between LINE and GEN. The area I live I'm is rual and looses power 1-2 times a month. I travel for work, so I am not always home when power goes out. My thought, keep needed circuits for backup power on GEN and then plug the Butanni(example) into the ac power outlet, there for constantly charging the battery. Or would this be bad as it would waste each charging cycle?

Could you do the same with an interlock kit rather than a transfer switch?

Excellent informative video. Notice you are running this from a Bluetti AC300 with B300. I can't find your review on this system, although you do have a discount code. I'm looking to buy an AC300 soon, and, would very much like to see your review.

Jason What type of transfer switch can I use if I have an AC200P and a 7500 watt gas generator? Can I get one with more than 4 circuits for when I might use the gas generator?

Hey Jason, was the transfer switch a diy or did you have an electrician? Also, are you going to upgrade the main power station (EP500) or add additional batteries? Thanks again for vid

Jason, I have almost an identical setup with a Bluetti going to a transfer switch. I purchased some solar panels for the bluetti, but I'm wondering what else I need between the panels and the Bluetti in order to get it permitted. I'm thinking it would require fuses and a quick disconnect. Do you have any thoughts or info on this?

Hi Jason, awesome video, love it. Any updates on how this set up is working?

So if i have an existing manual transfer switch (Emergent) I can replace my portable gas generator with an Eco Flow or Bluetti backup solutions?

I'm waiting on someone to make a video of hooking up a 48volt Lifepo4 battery to a Bluetti to extend the run time, I tried hooking up a lithium jumpstarter battery pack to it, (with the cigarette lighter adapter) and it charged my bluetti at a 100 something watts under the DC option, with a 48volt battery I would imagine someone could use the PV aspect of it for more watts coming in

Hey Jason, Which panels did you purchase to generate the 925 watts?

Why don't you connect your AC300 to the grid and set a charging level eg 30%? You could run your most important circuits all the time with vor AC 300. First your solarpower would be used (from 100% to 30%) and if there isn't enough solar and the charginglevel ist to low, the grid kicks in.

I have the AC300 as well and was wondering in the manual it says 150 volts max on input DC and I have Renogy 100 watt panels. Each panel reads 22.5 volts so I have only 6 per DC1 and 6 per DC1. Any thoughts?

I am looking for solution, to charge power station from mains during night from main electricity line, when it is cheap, from 11pm till 8am, and the use the electricity from the power station during the day. I presume I would need some kind of a switch, which would control, when the power station should charge itself, and when it should use it's juice to power our 2 bed apartment. Any recommendations which model would be enough four our 3 people family?

Is the neutrals bonded with the house when you have the power station connected?

Can this one work with the Bluetti AC200P and/or the Ac200Max? I know Bluetti offers one of these to install to your home. But, they state it works for the AC300 and AC500. I have both the 200P and 200Max.

Would I be able to plug a Bluetti AC500 into an existing 30amp receptacle that has a transfer switch on our main panel? We use this for our gas generator and I don’t want to make an expensive mistake when we get our power system. Thanks!

What is the cable you are using for the AC300 to the manual switch ? My manual switch have 4 prongs yet the BLUETTI is only 3 prong?

There is one issue I've heard people talk about which has me concerned, most solar generators have a floating Neutral, which could harm your power station if you were charging it and running things on the transfer switch at the same time.

So if you place the ttansfer switch to generator does it trip your main breaker?

I like this @

In this set up, how do you charge the battery directly from the grid when needed? I'm assuming the transfer switch only receives power from the battery and can't charge the battery from the line

Thanks for this idea! I have 24 panels in my house but no batteries... I wanted Teslas Powerwall for a long time but now I want the Bluetti AC300+B300 combo because I can keep adding later on. What is the difference between your transfer switch ($350) and the Bluetti Smart Home Panel ($1,499)? For me they look like the same type of thing 🤷🏽‍♂️

Does this setup run your furnace? How many watts does your furnace draw?

Hey, I'm looking to buy a Bluetti power station with a B300 battery. Although I don't have a solar panel, I'm interested in installing a transfer switch. I have a question regarding its functionality. If I connect the Bluetti power station to the transfer switch, can I also keep it connected to charge with the grid? I intend to use it as a backup power source, similar to a UPS. Is it possible for the Bluetti power station to automatically provide power to my condo if the grid power goes out, just like a UPS does?"

How can I install the transfer switch inside, where my power station is while my main breaker box is outside?

Interesting video, thanks. But I was looking what you had to the right of the video.... Loads of can of food... Or cans and can's of beer?

What is the best solar generator to charge an EV?

Hi Jason, great video. Also would it not be a wise investment to go with Signature Solar 48 volt split phase all in one unit with a 5kWh server rack battery for a total of around $2700 instead of $3600 for the Bluetti ? The Signature Solar system would offer more options and capability than the Bluetti. I do not work for Signature Solar or have any vested interest in that company. I am only pointing this out from a value per dollar for the consumer and as a better/cheaper way to power your home. Also if you want portability you could mount that equipment on a roller cart as I know the Bluetti is portable somewhat.Let me know your thoughts. Thanks for a great channel.
