We appreciate your contribution to improving our offerings and hope to keep you updated on the progress. Thank you for your dedication to quality and transparency. Best regards, The Growatt Team

I called Will out on pulling his Growatt Video. I've always trusted Will's reviews. But I found it odd that Will blasted Growatt and then the video disappeared. I praise Will for reposting a edited Growatt Video. Will's channel is hands down the best Solar and Lithium KZfaq Channel!

Yea, don't take negative comments in at an emotional level! LOVE your work / contribution to all of us!

These companies are moving more towards software-only capabilities because they want the most important data they can get from you - your *personal* data. Thanks for continuing to champion units that do not require an app to operate them.

Looking forward to a PROWSE designed power station someday. Thanks for keeping us safe and manufacturers honest.

Just stopped by to say to you Will,, thanks for your help in giving us ( the veiwers) straight up info , no bs or straight up shpt,,, need more humans like yourself on this planet !!

I saw the original video and enjoyed it. Also saw your note that you removed the video. So also enjoying this video. Whenever you make a mistake, it's definitely the right move to delete the video and start over. Even if the product is a total piece of trash, you still have to be accurate in your review. That has nothing to do with being afraid that the manufacturer will be angry that you pointed out that their product has problems. Everything you said in this review video sounds good.

Thanks Will for all what you doing!!!

If they are selling it, then you are doing the right thing. I left a comment the last time because I thought they weren't selling it yet. Growatt is going crazy if they don't take this out of the marekt.

Will, the community really appreciates the work that you do. I've learnt a whole lot from you. This growatt unit reminds me of the 5000ES with all the safety concerns for the US market when it was first released

Nicely done nicely done Will.

Thanks Will, You are the BEST. Thanks for reposting this video with editing!

Love your honest and emotionally intense reviews ! It is criminal what some of these corporations do t o us and try to pass off things as infallible .

With everything being equal, I'd say the new benchmark for power stations/ solar generators, is the Hysolis unit. It has a almost perfect design and function. Plus it has great features that compete with diy systems. The one thing that could be added to all of these systems is a CME/EMP protection device built in, and make it replaceable in case of a CME or EMP does occur.

Just saw the video. I purchased the 2000 because Hobotech said it was the best value. He praised it and didn’t show any of the problems you talked about. I am only using it for emergency backup during power outage. Thanks for what you do. Love your book.

Interesting contrast with another well known KZfaqr's review yesterday, in a similar space, who gave far more positive feedback on the identical product. Very useful additional info here, thank you. Now revealed to be a case of "buyer beware".

Gosh the XT60 is such a fundamental error for them to make - astonishingly, it got into production with that dangerous flaw - You have probably saved a few fires there Will - well done!

I saw the vid yesterday before you pulled it. Glad you did this follow up vid. Great info as always with your no opinion / fact held back, call-it-like-it-is reviews.

Watched from Yosemite Kentucky. Thanks for the educating us!

I have no reason to doubt your word! I consider you a very ethical person and a master at your craft.

Thank you so much for your invaluable review with detailed comment, and warning about use of same type electrical connectors for different purposes, and different power characteristics.

YES! It's back! Thank you, Will!

We appreciate your fair and impartial reviews. I purchased your book and I watch your videos. You're a man of honor and anyone who says otherwise is either foolish, jealous or just needs to watch more of your videos, LOL!

Thanks, Will. As I mentioned in my long comment on yesterday's (now deleted) video, the XT60 plug, in general, is sore point. Any solgen that has a DC input of 60V or more should have a connector that twist locks into place, such as what Bluetti is using on the AC200L that I now own. I destroyed my Growatt Infinity 1300 when the XT60 managed to wiggle itself loose while 600W of solar coming in. Reinserting the plug caused an arc that fried the electronics inside. Growatt honored the warranty and I got a full refund. But all of this could have been avoided with a decent connector. And, yes to all of this that you observed . . . 1) Don't use the same connector on matching boxes that serve different functions. 2) Physical buttons are always better than a blank slate of plastic on the case and a flaky app on the phone. 3) Don't step back to 60V on the DC input when your previous flagship model (with a smaller battery) had 100V. I do appreciate the manual Bluetooth and WiFi on/off control on the front panel button, as Hobotech observed in his review of the Infinity 2000. Thanks again.

They were in an obvious hurry to get this on the market, and it shows. For once I managed to watch your first video before you took it down. 😊 I didn't get notified by youtube, but today I did. But I did turn off and back on notifications for your channel.

I have the perfect idea, Will Prowse needs to find investors to start a business and build the perfect portable power station!!!

Great Call, admitting a mistake, far and few people in this world own there mistake(s). Thank you Will for your Integrity. Will Prowse - "he is known to be a man of integrity"

What service you provide, and for free! It’s still a lot cheaper to pull the product temporarily, make changes before you have thousands of potential nightmares. (If you provide a non public assessment for a fee, that would be amazing for you and the manufacturer). Great job again, Will!

Very quick response, hope you were not up all night.

I just bought one of these after watching another guy on yt praising it. Good thing I can't find the expansion battery anywheres. Thanks, wish I saw your video first. Guess I'll keep it for backup and go Ecoflow for main unit.

Great update 👍🏼 I wondered if you’d add a part two to the Growatt review. IMO, this was the right move, remove the previous one and post your dislikes. Thanks for all of the great reviews.

Zero viewers ever think you would fold to a company… we all trust your honest reviews. Posers might think you would, or might imply you would. Thanks for making this video pointing out to the naysayers.

You are right about being able to view and set EVERYTHING on the unit. I can tell I'm getting older (40s). I really Don't want to have to use software, especially requiring internet connection to use, setup or monitor equipment. It should be stand alone as a baseline. Download firmware updates to a USB drive via computer then plug it into said device.

Thanks for maintaining integrity! 👍🏻

You saved me!!!! I was about to buy, & would have made those mistakes and caused myself a lot of misery. I am poor & can't afford to lose money on a bad product. I wanted these because they claim to work in cold conditions. Thank You!

I have owned VITA 550 for over a year. Sadly it has the same construction design this model. The is the same port on the end that goes straight to the battery. I however don’t think it has the same voltage as this model. I only plug it into the wall when I need to recharge it. Now I am glad I never invested in the solar package. Thanks

Great video, as usual. 48V nominal DC systems, which can (especially while charging) be about 55V or a bit higher are generally considered by electrical engineers, OSHA, Edison Institute, etc. to be “safe” and subject to the 50V or lower rules. However, building inspectors have their own interpretations and a lot of power, so in some jurisdictions one may have to treat them as over 50V systems.

Your videos are excellent! Thank mg.

Great video. Could you do a video on plug and play grid tie for small solar systems. Like Vevor solar grid tie micro inverter.

Fuck the haters, Will. Also, could you someday do kind of a throwback to the RV days and make a video on the ultimate modern mobile solar/battery setup?

Very Well Put Will. You are a credit to the industry. Bob in Wales. 🤔🌟🌟🌟👍🙂🏴󠁧󠁢󠁷󠁬󠁳󠁿🇬🇧

Nice followup! Much respect!

I am lucky, I saw first video!

So are they just using you for major free consulting??? 😂😂😂. “Let’s send Will our crappy pre-production crap, he’ll exhaustively dissect the issues and hand it back on a silver platter. Under threat of lawsuit if he disses it too much”. That’s not fair. Your first video was perfect, and should help prevent future exploitation.

Great video. I can't wait to see feedback from the Growatt on the follow-up video.

Tier list video on top problems in solar and battery components when?

Thank you for the video Will. "Will is folding to a corpo!" Hahahahaahaahha.... oh my... he don't know you do he? Never change Will.

So, Will, i was confused at first because i had absolutely no issues with the app after getting my Infinity 2000...... Until i connected it to WiFi, and after that i have been unable to connect to the infinity 2000 over bluetooth or wifi There is good news, if you put your phone in airplane mode, and turn bluetooth back on, you can connect to the device again

@3:15 ( LOL ).. "IF you have a Port, but don't have a module for it"..... Isn't that where Bluetti is with their AC200L and that silly 48 volt port that replaced the 30 amp 12volt Aviation Port ?... PS: I noticed they have reintroduced it on Newer Models ..

Really fine work Will ! To your point about the app vs. the physical control of the unit is excellent. What happens if the internet is unavailable and you need to make a change?

I’m having a very similar issue with my EcoFlow River Pro. It’s been on 1% for the last 5 hours.

Thanks ... GOOD POINTS one & ALL COOP ...

I'd love to see your insights on the Anker 3800 Solix .

Great video will. Other than being expensive camping toys they are really just over priced junk.

Will, As always you do a great job. Thanks for all that you do.

Always safety first,then buttons/switches.

Good job Will, sign me up when you create your own system, excellent work.

QUESTION: Building a house right now, I am searching for a charger/inverter quite like the Tesla, or the Apollo 5K (all automatized), BUT a unit without battery. I have my own 20k-ish Watt LiFePo batteries, I don´t need them nor the massive extra costs which come with the Tesla unit or the Apollo one. Any suggestions?

Thank you sir goooooood videos

Please do a review for the Growatt spf 6000 es! Off grid inverter 😊😊😊

large channels can edit videos and upload it on the same video, the likes and views stay the same, its a feature mostly just news channels have tho

Thank you I myself will stay away from these thank you for sharing this six stars

Good work Will!

Honest review. Thanks Will.

I have an Anker C1000 PPS. It's loud and annoying. They completely cheaped out on thermals. Have Anker send you one to tear apart. The Anker 767 (now F2000) is quiet, the rest are not so much.

Thanks, Will. 👍

I wish he would test the Eco-Play generator, it needs a review

Excellent once again, man! Thank you!!

So I'm only a couple minutes in but I'm assuming WIll and others have pointed out that this Growatt Power Station is probably one of the most popular designs out there. Grecell, FFPower, Oukitel and many others have slapped their name on this design (with some minor changes overall). Those can be had for under $1000 all day long so the price on this makes no sense

Excellent explanation

Great video...Would you test the segway cube?

Something to compare by, one video then the fix.

I saw that same comment, people just love doing that these days.

Hello can you please please please make a vid on how to setup the load on a charge controller..i dont know what wire or anything else i need to to hook up to lights and fans.🙏🏿🙏🏿🙏🏿

I was on the website this morning and you cannot buy the Infinity 2000 with the extra battery or the option with the two additional batteries so maybe they finally listened to you. Have you gotten an update on this yet? I have the infinity 1300 and I still cannot get the app to work work their app is horrible. The Infiniti 1300 help me get comfortable around solar then I built your EG4 cart build LOL I came here hoping you had a review on this infinity 2000 and how you could duplicate it with the 2 extra batteries and the various outlets on it on a cart type build what the price difference would be. This is the first video I found of your reviewing on it this morning.

Hello 😅

How did that other big channel miss all of this?

Good job. Well done

Still waiting for Anker to implement some of these fixes. Their solar input requirements(limitations) are ridiculous.

Thanks for your videos

You sent in a list and they are like, wtf are you? Lol

None of these solar "generators" have enough capacity to justify their price in my book. You can DIY a better setup pretty easy. I did this years before these "generators" were even available. I really liked the 48v setup you built on a the dolly!

Gotta tell Francis and T to get it together over there 😂

Assuming that Growatt fixes all of the documented issues, what differentiates this product from other products currently on the market from other manufacturers?

If it’s bad it’s bad and deserved to be called out. As ever Will you do the consumer a service with your objectivity and transparency. Thank you.

Love this channel and the work here. I don't think it's fair to say to fire the engineers on the project as we don't know the conditions at the company, deadlines or anything else that went on that lead to these issues. The issues are very bad, that's clear but even very good engineers make mistakes with poor leadership, bad timelines or their concerns are side stepped for the sake of making the quarterly P/L statement. I don't think we have enough information to attack these engineers. They don't have the final say in their timelines or what's released.

Ok, I'm an entrepreneur and I want to enter the competitive market of "Solar Generators." (1) Design & build it but, let Will Prowse look at it prior to releasing it. (2) Hire Will to be on your design team, or perhaps the best option...(3) Just Pay will to design the damn thing from the beginning and avoid the embarrassing & potetionally costly mistakes and lawsuits!

I have a growatt inverter I got recently, it's been mostly a headache, the thing randomly decides not to charge the battery so I have to restart it, even though there's no error message. The wifi dongle likewise just refuses to connect to the central server despite the blinking light implying it's working and it also just refuses to connect to the 2.4ghz band of my router for some reason, and the app is just terrible on top of it, crashing constantly, connection issues etc. Whoever is in charge of that company has no idea what they're doing.

Be interested to see if grow watt provides any feedback!

Quick question. I have two 3500 watt eco delta pro as backup to my solar plus in my camper. It’s a 3000 watt inverter and 300 amp batteries when those die I just plug in the 30 amp delta pros. But how do I keep them from recharging the 3 100amp batteries? It starts to drain them as soon as I plug in. Please help

With the XT style connectors: it is important that battery outputs be tied to a FEMALE XT, NEVER a MALE. When a male XT is wired into a battery, it makes a hazardous opportunity of shorting that connector with a screw driver or random piece of metal. (statistically speaking). Just by changing the XT polarity to "socket" (female) on the battery unit, would solve this particular problem.

Only good suggestion i have about Growatt - stay away from it!

Most of these companies are obviously not designing their own power stations, they are just branding OEM builds and have very little in-house expertise themselves. Not only are they unable to recognize problems before the units go up for sale, they also have no real ability to fix any of the problems themselves. This reminds me a bit of the "new" Sungoldpower all-in-one.... except it isn't new. Its *exactly* the same hardware that Renogy used in their all-in-one 2 years ago... complete with all the bugs and hardware design issues. The design literally wasn't changed at all even after 2 years. And even the OEMs are often oblivious to serious issues. Very few brands have enough pull with the OEMs they use to actually get issues fixed. Eco-Flow might be one of the few that actually fixes things (or at least tries to), but it's an expensive eco-system to buy into. I have two Oukitel P2001's which I love dearly except the AC output plugs swap HOT and NEUTRAL and the fan doesn't turn on soon enough. I hacked the fan (just added a resistor in parallel to make the firmware think that the temps are hotter than they actually are), but so far no luck getting the units torn apart well enough to be able to fix the HOT/NEUTRAL swap. Fans not turning on soon enough, and cheap fixed-speed fans instead of PWM fans, seems to be a cancer on this industry. They all focus on trying to keep the units quiet and let the power electronics inside fry before turning the fan on. Drives me nuts, because it vastly reduces the life-span of the units to do that because they are allowed to overhead even when running at low loads. In anycase, as an electrical engineer myself (by education and trade for 40+ years at this point), I completely agree with your criticisms of the unit. To be honest, I always wanted a battery port on these power stations... just a straight connection to the battery (through the BMS of course), to the point where I open them up and add the connector myself. But I would never make a solar input and a battery output connector be the same type and size. -Matt

Will have you heard of a Rubix rb5100 battery?. A local guy sold us one have never setup our solar. This battery is still in the box. The manual isn't real helpful and this company doesn't have a website.

Any Chance to look at Goal Zero's newer smaller offerings? (Outdoor Models, Yeti 500/700)?

Would you do a video on the Anker f3800. Thanks

I wish both this, and other other batteries did, is have a charge rate button, a charge state button, and an auto-on function, all of these buttons should just cycle through all available options with a small indicator on the screen for the current option. For charge state it wouldnt be realistic to have every charge state down to the 1%, so maybe 2 buttons with intervals of 5% one button for the minimum charge state, the other for maximum charge state. Also i dont know if anyone has tested, but the IOT on/off button may be reset every time the powerbank is turned off, i would like it to be a saved toggle. I also agree i would like GaN and a 30-300v charge range(i do like the lower voltage in case i want to bring it somewhere with a single pannel, though that can be achieved through a second plug. I did end up buying just the battery station+solar pannel, but this was before the ANKER was on sale for the same price, IIRC it was $150 more when i looked at it, and i plan to just use this as 'high end' UPS that i may wire up a few solar pannels to, as this is for my server rack that only draws a max of 500w, even when transcoding recorded TV shows. normally it runs under 200w when not recording or transcoding. My Ecoflow is under 2 years old and has already gone bad, but thats the LiPoly version without a way to set maximum charge state, it only runs for a few seconds without grid power before shutting down so i've unplugged it and am using a traditional UPS for the time being, sure it doesnt run as long as the ecoflow, but at least it turns back on after the battery completely drains, and i dont have to worry about it catching fire now that i know the ecoflow batteries are bad.

I won't buy any product that I have to use an app to reach all features. It either works on it's own or I won't buy it.

According to Google, 25 mA at 50 Volts DC is considered dangerous. I believe these units can produce more than 25 mA.

We could have rugged, iconic, box shaped, easy to use, long lasting, well thought and safe systems Will, but they cost 0.002 cents more to produce.
