[@ThreeDigitIQ]

This video deserves a follow-up and at least a title change now that Yoshino has been exposed for falsely claiming "SOLID STATE"

[@johnnysweekends]

Did you see my latest video? Ill have another out shortly

[@steveanimatrix3887]

I stopped at "600w of solar input." That's pathetic. Even the AC300 has 2400 watts solar input, which is still low in my opinion, unless you live in Arizona or something and have constant sun. It's like having a Ferrari with a 1 gallon sized gas tank.

[@teuton6167]

Or a full sized gas tank, but you need to fill up the tank using an eye dropper.

[@claytonyoung1351]

Same. 600w of solar input at 60v is pure trash

[@theMekanik]

Agreeed Zandura does it with the same Battery Type 120/240 and DC power through the AC charge Port.

[@ScalzoPhoto]

@@steveanimatrix3887 Actually, I think with every extension battery you add, it also adds 1000watts input solar. Which makes sense…. It is compact, but if you need more power it is expandable

[@steveanimatrix3887]

​@@ScalzoPhoto No, that actually doesn't make any sense. Never heard of PV input on an inverter increasing the more batteries you add behind it, only the capacity. The max is controlled via the fixed hardware capability in the inverters charge controller.

[@aznick102]

Happy to see more competition - hopefully causes prices to fall.

[@johnnysweekends]

Normally does. The more products available the cheaper they get.

[@deadonleprechaun]

I couldn’t agree more.

[@jonschlottig9584]

I think these guys just threw down the gauntlet. It may not be built as tough as some of the systems I've seen, but it seems like by far the best power station/ Solar Generator out there. Throw one in a rolling toolbox and strap a solar briefcase to it, and you're good to go.

[@billderinbaja3883]

There are some advantages to the Yoshino, but I'd recommend you update this video based on all the recent testing and reviews. Not solid state... solar input is inadequate.... but size and weight are advantages.

[@liamdrew7548]

Got an AC200Max + 2 x B230 expansion batteries (so about 6144Wh of storage) and about 2.2KW of solar myself. I think it would be nice if a lot of these vendors allowed for the solar input to be significantly higher than the output wattage. (e.g. If you're offering a 4KW output, the solar input should be double that) Based on the premise of having 8-10 hours of sunlight but a 4000w output (in this case), so with this unit you'd never be able to even keep up with the AC output and charge the unit. (not even considering efficiency losses in the inverter) Not picking on this brand, just an observation of most power stations out there at the moment and something I'd like to see.

[@johnnysweekends]

I agree Liam, I wish companies would ask more of us content creators or people who specialize in this stuff, about getting our input. Now not everyone will need crazy solar input because 2000 watts is a lot for the average person. Most use DIY people if we had space would go as high as we could….WHERE IS MY MEGA WATT??? !!! 😂 But yes higher input voltage and for a higher solar charge rate would be great 😀👍🏼

[@liamdrew7548]

@johnnysweekends agreed 👏 give us more solar ⚡️☀️ really appreciate your videos as well, the more knowledge is out there the better 😀

[@seniorslaphead8336]

I bought the Max with a view to expanding it when the battery price went down. Unfortunately Bluetti have kept the price of the expansion batteries very high. Ludicrously high... you can currently get an AC200p for £100 less than an expansion battery with the same storage and the redundancy of having all the duplicated electronics. From a marketting point of view it's braindead.

[@__WJK__]

Rumor has it, when an expansion battery is added to the Yoshino B4000, the unit will accept 1000W of solar.

[@johnnysweekends]

[@__WJK__]

Was liking the Yoshino until hearing the unit can only handle 600 watts of solar input. Also, the rather low lifetime charge cycles leaves a lot to be desired, especially compared to the competition.

[@johnnysweekends]

Agree..👍🏼

[@benniewalker312]

This pack looks pretty cool but I had a horrible experience with ecco flow customer service, and two separate packs that died on me in less than a month so I'm building my own battery pack. Because if something breaks I can just replace a part inside and not have to worry about all the headaches involved with dealing with the manufacturers of these packs, not to mention I can get a way better system setup for the price of one of these high priced packs

[@johnnysweekends]

DIY will also net a bigger unit for cheaper. Most people do not want to build anything so they would rather buy it built

[@heart4Pahoa]

I love everything about this unit…BUT, the solar input. Complete show stopper on buying it.

[@johnnysweekends]

Yea, 1000 watts would have been more ideal. Not that everyone will need that much, but 600 is a little low.

[@heart4Pahoa]

@@johnnysweekends It’s more about the ratio of input to output. 600W is fine for 1K max output device, but this is like using a Hydro Flask for fuel cell in a 68 Camaro.

[@HenryPlus9]

It seems that the Li-NMC batteries are better in terms of charge density and cold-weather charging, but LiFePO4 batteries are still better in terms of stability (low fire risk) and number of charge cycles.

[@johnnysweekends]

Lithium Ion is more energy dense especially when solid state. And they are the safest of lithium batteries even more so of LiFePho4. Solid state doesn’t have a liquid electrolyte so even if punctured they dont burn up unlike lithium iron will.

[@shelley131]

Enjoyed the video Johnny. Not sold on the Yoshino. It does me no good that it has 4000W of output and yet with the measly input from solar charging the unit is very limiting , to where depending on the time of year, your solar peak hours may average 4 to 6 hours of charging . It would be nice if it had at least 2 dual solar charging ports. I know the discharge test was above average, but I was not impressed with the efficiency it had when connected to your refrigerator. At that point the efficiency was 71%. I have the first generation Delta Max 2000 that provides better efficiency when running my 26cuft fridge that is very old.

[@johnnysweekends]

Unfortunately the killer of this unit is the solar input for sure. It does perform well though. The new expandable battery that I thought would be out already doubles solar input. So that does help. Although they are taking so much time and the way the market is moving this will have to come down in price in order to consider it unfortunately.

[@shelley131]

For the price of Yoshino I can buy any other brand and two extra extension batteries that will last way more than Yoshino can. Not underestimating Yoshino but the price is an instant deal killer.

[@mcarling6495]

60V maximum PV input voltage is dreadful. For comparison, the Hysolis Apollo 5K has a maximum PV input voltage of 500V. High PV voltage is important because it allows for lower current, which dramatically improves efficiency.

[@johnnysweekends]

Nice video! Non-starter for me. Waaayyy to little solar MPPT capability--IMO a mismatch of tech, but the other features are great. From a D-pro (x2) owner this would not be an upgrade. There's a niche for this I'm certain though. I hope you can pass that back to Yoshino. -BTW, A very Japanese sounding name, but made in....?

Thanks Bruce. Yea wish solar was a little higher. Japanese batteries and a couple other components I believe and then made in china. But that’s everything it seems 🤷🏼‍♂️

[@seniorslaphead8336]

I bought the AC 200 max when it first came out in the UK at what was a reasonable price at the time. A friend of mine bought the AC200p which is the same in many respects including the size of the battery when it was on "sale" earlier this year (Bluetti always has a "sale" on... if there wasn't a public holiday they'd do a sale because of the phase of the moon or because an employee had a birthday...). Interestingly the AC200p is currently HEAVILY discounted... I think they may be discontinuing the model and are therefore getting rid of the stock. It's a steal at £1100 (probably the same or less in $).

Good review, as always. For those of us who went with an Ecoflow product, that unit isn’t enough to sway us, probably. I’m using my Delta Pro everyday now to power my Keurig and some other things. Question: Is it bad to recharge to full capacity every day (solar) from 85-90% or should I let it get to 10-20% before recharging? Thanks, Johnny! Lots more sunshine down here in S. Oregon than up in the PDX area!

[@johnnysweekends]

Yea the unit has some potential for sure . More solar input definitely needed. And yea the DP is a unique unit for sure. As for charging the sweet spot would be to set charge and discharge limits to 20%-80%. Kinda like the Chevy volt and more they run the batteries in the middle to make them last.Z but very two or 3 months do two, complete charge and discharge cycles to recalibrate the bms. Now you could do 100% to 0 if you wanted but you’ll hit that 80% soc rate a little sooner. But still if they truly last 10 years till there, use them up. Don’t let them sit. That’s waisting money

To maximize battery life, keep it as near to 50% SoC as possible as often as possible. Where to set your minimum and maximum limits depends on how much power one needs to draw daily compared to the capacity of the system.

The yoshino is more powerful than the evoflow but only for the largest units. Why is it that tge smaller yoshino units are equally as powerful as the smaller ecoflow units like the river models for example. Maybe this is just a limitation of ssb? Im leaning towards the yoshino but id like to see more of an ecosystem with their offering and how good their cs is.

Also why does it have less cycle life than the ecoflow. I thought ssb are supposed to have a higher life span .

[@Golfreak]

Just curious as the advantage for solid state ? I mean it still weight more than the Delta which is Lifepo4(yes I know it has a little more capacity) and the life cycle is less than Lifepo4. It's downfall is the >$1 per watt hour. Most unit can be had for

[@johnnysweekends]

Much much safer over all for thermal runaway and puncture and also more power per pound. Even though it was more weight it has more power and more watt hours so essentially it’s lighter

[@michaeld4502]

To much money can buy extra battery to get more power This is like a startup company in power station world asking more than the leaders who have track record.... only this is Solid State battery with less life cycles.... who knows how safe they are compared to LFP... if priced like $2k area would sell a lot and take sale from Ecoflow and bluetti.... but solar needs to be 1k so it charges in 2-3 hrs then this is a serious contender enough solar to charge during the day and run minisplit is what people want .... can run vans off-grid and emergency plus it's lighter than LFP

[@johnnysweekends]

Solid state is actually much safer. But yes to the others 👍🏼

[@770Noe]

I'm not sure if it's worth buying the Yoshino. The Yoshino will power the same devices that a Delta Pro will for roughly the same amount of time (I don't think that 2-3 hours more is worth the price difference). The delta pro is cheeper and will get the job done. This technology is recently coming out and will be very expensive at first but as competition grows the price will drop bit it will take a while. I think the only reason I would buy the Yoshino is because of the weight if anything because if I consider the features, the Yoshino provides less of everything. . . . it's a minimalist generator.

[@AlexanderBell1847]

By the way, the Yoshimo is selling now at Home Depot for $2,500 which is the same price as Delta Pro, I think.

[@johnnysweekends]

@AlexanderBell1847 interesting ill have to look and see

[@leny7829]

Looks interesting but I'm concerned about the 2500 Cycles vs. Delta Pro is around 6500. I know these are some "numbers" but a head to head comparison would be great so there can be apples to apples comparison...especially regarding the cycles to expect before degrading?

[@johnnysweekends]

Well you have to consider these are estimates and also 6500 for delta pro is to 50% soc and 3000 to 80%. And again estimates. It could be worse or better for each model. Solid state will be more common

[@leny7829]

​@@johnnysweekends I know it is estimates in ideal conditions but thanks for explaining that the 6500 cycles is to the 50% level whereas "only" 3000 to the 80% level. That's important information as now seems comparable as for this criteria in deciding between Ecoflow v. Yoshino. The sales puffing of the 6500 would distract newbies like me so if you do make a head to head comparison, that'll be a good thing to point out. Solid state does seem like the future. Just purchased a computer with a solid state hard drive as my old spinning hard drive crashed on me. It would also be nice if you can comment if this MIGHT qualify for the 30% tax credit lit the Ecoflow is saying.

[@mrs.c5471]

I’m confused, when you were testing the blow dryer you said you had disconnected the PS from the RV, yet your sine wave tester appeared to be plugged in to the RV?

[@johnnysweekends]

@mrs.c5471 so the BT4000 is still plugged into the watch dog and the RV but hair dryer is plugged in directly to the back of the BT4000 so info will still show on the oscilloscope

[@antimatterhorn]

I have my doubts that this is even a SSB. I haven't seen anyone do a teardown to prove it, and by your own weights, it has nowhere near the Yoshino's claimed 2.5X energy density boost over traditional Li-ion chemistries. In fact, it appears to be slightly worse (for energy density) than the chemistry of the Ecoflow. Something is definitely fishy here, and I would not be surprised at all to see someone open this up and see a bunch of UPP batteries wired in series inside. Li-NMC is just the cathode chemistry, and this has been used in Li-ion batteries for decades, so that isn't an indicator of it being a SSB. However, since they do claim it is Li-NMC, that means volume changes are going to be a nightmare during charge cycles, so either they've fixed that with chemistry or there are a bunch of thin sheets bonded inside that unit, or it's not a SSB.

[@aznick102]

Watched this again - so it says "pure sine wave" on the two AC plugs - when you plugged into your 5th wheel as "house battery" are all the AC plugs able to be used? Have to think the answer is yes, d/t your comment about using microwave, but can you confirm that for me?

[@johnnysweekends]

Yes this unit like the delta pro act as a generator or basically shore power. The transfer doesn’t know the difference. So I can run everything in the Rv like normal, 👍🏼

[@happyhamster1411]

Only thing I’m not so crazy about is the 600w 10a solar input. Pretty underwhelming for such a unit

[@YoshinoPower]

As the compact size and light weight are priorities of this unit, we believe 600W solar input fits within the application of this model. Also by maintaining 60V and 600W input we are able to achieve full ETL safety certification that wouldn’t be possible otherwise.

[@teuton6167]

@@YoshinoPower Thank you for the explanation. But you need to understand that few people can get the full 600 watts into this machine-as the video shows the 60 volt limit means 300-400 watts is more realistic from most solar panels. People want a solar generator that they can use and charge in one day and this one can’t. Add an expansion battery and the situation gets twice as hard to recharge. For $3,000+ dollars the public expects better solar input. Just look at the comments and you’ll see a theme on this point.

[@A.C.71]

Would it harm or impede the efficiency of the ecoflow delta pro to have it in a unheated garage where things may get cold enough to freeze or would it be better to put it in the house?

[@johnnysweekends]

Any power station or battery will do better in controlled conditions such as a 70 degree garage. You can still use these in harsh environments but charging at 32F and below is not possible till the unit warms up again and obviously over temp in extreme hot will cause problems as well. If you can keep it warmer that would be better. Some people use dc warmer blankets like heat pads for batteries and more. Cost is cheap and power draw is reasonable.

Most people probably won’t need more than about 600. Even camper vans our limited with roof space so 600-800 may be all they get. And that would be fine. I run 2000 watts on my Rv. But I also went extreme to also be able to test things as well.

[@dogedogego]

Is it UPS or EPS? Major difference between the two for the intended use cases

[@johnnysweekends]

UPS for this unit.

All depends on RVs Ac unit there are several and new is more efficient than old

[@socksonfeet8125]

Whats with the marketing of calling these battery units generators? They arent self generating anything...

[@johnnysweekends]

It was a bad name that seems to have stuck. Hence most of use reviewers call them power stations. It’s a box that has stored power lol

[@John_thetrader]

with cobalt ... i wouldnt want that in my house or rv ... those are also in the cars that catch fire ... Lifepo4 is more safe in my eyes ... eve cells or cat cells ...

[@johnnysweekends]

Solid state is actually way safer. Hence this new tech coming to power stations is really cool. But most of the items you have used and still do have a NMC battery.

USA based company from what I can see, using Japanese batteries and built in China. Hardly anything is made in USA anymore 🫤

[@johnnysweekends]

Ahh nice. You would be surprised how many companies disguise them selves and then promote their own products. But yea unfortunately the Yoshino has awesome tech but missed the mark on solar and the price unfortunately. They better hurry because everyone is moving fast and this unit is almost gonna be obsolete.

[@off-grid-solutions]

@@johnnysweekends No I don't work for them🤣 I have a tiny tiny hobby channel on here to talk about the stuff I use and Montek impressed me so much that I also run a little Facebook group for Montek UK users too because I like the underdog . Sometimes the overlooked underdog blows the huge competitors out of the water but nobody knows because they are blinkered by the big two . See your comparison to the big two . Perfect example 🙂 So yes I guess I do promote Montek but not because I work for them , because I don't . More because once you've owned one you would understand 👍

[@johnnysweekends]

Size wise it’s only lightly larger. Just shows how much power out of a unit that is only a little bigger and 1.5 lbs heavier. Just advancements in tech

[@ragemodegaming7962]

Calling it a "solar generator" is quite the oxymoron indeed. The sun is generating the power being sent into the "generator", so it's not "generating" power at all, merely storing it and passing it along to your devices, etc. "It's a solar generator!" "So it generates sunlight?"

[@johnnysweekends]

Solar generators is a search term. And a poor name giving to these. Hence i dont say solar generator in the video anywhere as its a power station. It just stores energy generated by solar panels that you connected to it. Or stored from another power source like AC from the grid

[@CloudzGamingGG]

Can you run a 1000 wat led off this ? If so for how long roughly

[@johnnysweekends]

Yes. A 1000 watts is a 1000 watts per hour. So how ever long you leave it on that’s how watts it will use, a 1000 watts per hour

[@larryc1616]

It's too expensive. Do they have a cheaper model under 1500?

[@johnnysweekends]

Yea they have other models. The link in the description or comment section will take you to the main page to view

[@warrior9086]

THXs for the info and test. I was in the loop first day this generator was presented in Vegas and at first glance it all looked very exciting. Even so I like some of the features and the new battery tech but compared to other solar generators this is a useless piece of shºt. I hope the customers and the competition will show their MARKETING department how to design and built a good solar generator for todays world..... and I hope they will listen. I hate good technology go to waste

[@adr2t]

This will sound silly - but do they give a safey test such as what happens if you was to let say damage the cells in anyway? Solid state is said to be able to be cut into and be fine, can these do that as well? If not - they're still bit of a ticking time bomb.

[@johnnysweekends]

Most all these are tested just like a car with a bomb under the trunk. In a worst case scenario If enough damage happens, then sure the energy of gasoline or a charged battery needs to go somewhere. Not most people don’t throw there power stations around. But even a 3 foot drop and most time they are fine.

[@adr2t]

​@@johnnysweekends Some solid state batteries can be drill into and be just fine or even cut. Thats why I was asking. The cause it that they dont have the same thermal run away issues. Didnt know if these also had that same properties or not. I am sure you would never test just pulling a cell and hitting it with a hammer would you ? lol

[@johnnysweekends]

@adr2t yes both LFP and Solid state or even semi solid state have less chances of thermal runaway from shorts or minor damage. But anything damaged enough, well they still hav energy that needs to go somewhere. But yes over all safer.

[@lighto999]

can u charge with DCDC car alternator. charge?

[@johnnysweekends]

I don’t know. Some car alternators can be a little funny so it depends on the car alternator. If it can put out a Dc voltage in that range then sure. I wouldn’t see why not. But the smart ones make it more difficult I guess.

[@wildwillyprepper]

[@christosl4395]

WHAT about life cycles ? 2500+ only ? lifepo4 i think they have 5000+ ...

[@johnnysweekends]

When I talked to them at the show before they were released 2500 was a conservative number they said. Which is good as it will probably do much more. Verses LiFePO4 are around 3000-3500 in most any power station. Higher in just a battery alone.

[@YoshinoPower]

2500 life cycles is the equivalent of using the power station every single day for 7 years, 0-100%. Even after that length of time there will still be 80% capacity left in the battery.

[@vistasdelpinar]

It's too expensive for what it's. it can't compete with Ecoflow or Bluetti

[@johnnysweekends]

@mattjudd5275 the Yoshino has a very good wave at full power. And a allowable amount of distortion. The Yoshino tested well over all for efficiency and power but the lower solar input and no ac and dc charging kind of lacks. The ac and dc charging can be fixed in a firmware update im sure. But the solar input will remain

[@user-ut7kh7pw3l]

Too expensive. Better get the Ecoflow

[@janetjacks3406]

So not lithium iron phosphate then but NMC - (lifePo4) so wont last that long.

[@johnnysweekends]

I bet they last almost as long or just as long. Most companies inflate there numbers to look good and I have noticed the numbers have not gone up but down by 500 cycles or so. And they said we are being conservative at 2500. So I bet pretty equal in the long run. But its also how its used, how its charged and more that will determine its over all life. Like with anything

[@janetjacks3406]

@@johnnysweekends I suspect they are not inflating their claims as the lithium iron phosphate batteries have basically much longer life spans, this is just a fact but I am sure reflected in the pricing. Jackery on the other hand are NMC, but obviously trade on their name so over expensive.

[@brucealmberg]

It's not solid state, does not have solid electrolyte. Large SS cells for this kind of application do not yet exist. If you claim it is, you know nothing about battery tech and have no business doing reviews and spreading false information. At best, it's uses hybrid battery cells, but more likely they're lithium polymer pouch cells. If you really want to do a proper review, tear it down and check the cells. Who makes them? What battery chemistry is used? Will Proust did a teardown of a similar "solar generator" with similar specs and false SS claims. It did not go well... This is probably the same Chinese company with a new name and new design but same cells and same false claims.

[@peterryan7340]

@johnnysweekends Yes, I can. 1. You lead us to believe that this is apparently a solid state battery but looks like a slightly modified NMC. 2. You provide little to no discharge data at any C Rate. 3. You provide little to not recharging rates. 4. You obviously have a little knowledge about oscilloscopes and ask us as viewers to help. 5. You then tell a viewer that his opinion is rubbish about the Apollo 5K

[@johnnysweekends]

@peterryan7340 1. It’s a solid state battery per what the company states and from what we saw at the show in Vegas. Would they lie..? Not sure how you could determine it was nmc unless I took the unit apart. Maybe you should talk to them if you want exact clarification on that. 2. I provided one real life scenario for discharge rate or expected run time in a power outage. I then did a full discharge test at almost the exact test temp of 77F at the specified C rate. Did you even watch the video ? 3. I did not do recharge rates as many people typically dont as its not as useful data for most and most people move on from it so its waisted time and effort. 4. I have more knowledge on oscilloscopes then most people but not as much as a pro user who uses them every single day. Like you there are people who know way more than you and way less. So when it comes to these scopes I know more than the average but still learning as these are not something you learn in a year or two. Hence if there is a pro user watching I would love that input. Hence this is how you seek knowledge. Verse making assumptions on ones actions. 5. Why would I even discuss a nonsense comment? Let’s discuss something that is $5000 verses something that is $3000..?? Not exactly apples to apples at all is it? So how would you even compare the two. Nonsense comments will receive one in return if I have time. My 5kw battery is better than your 2.5kw battery. See how that looks. The Apollo is fine, but put a unit up against it that is close in specs or at least price. I hope this helps clear some things up for you.
