@@clinton9129I believe he made an update video. I will find the link and attached, but apparently the case is now plastic, all but eliminating the chance for shocked.
Wow. Will, I'm glad you're still with us. Looks like you'll be adding a few more safety checks during testing. I know the 40 volt shock I got while testing the hook up on my solar array wasn't pleasant. Between your shock(s) and the no-fire fire of that one battery you tested.... let's just say your community of followers and supporters need you to stay safe. Appreciate you taking one for the team. Ralos.
Since you are always taking the right steps to not get shocked, never really thought about a scenario like this. Will be praying for safety while doing your videos.
Yep, u always have to ground it. Plus, any testing on a system like this ( with live DC from Solar/PV Panel, DC from battery, and potential for any AC/DC from inverter or transformers...not to mention the juice in any capacitors...u have to take safety measures While multimeter testing....by plugging in a 3 prong grounded extension cord in a properly grounded household outlet & putting the other end in your pocket. The shock will travel from your body to the grounded extension cord safely. * Also I'm assuming your elbows were bent & the shocked / current passed thru your elbows. At that amount of current (Amperes) if one of your elbows was straight (as in reaching full extension) the current would have traveled straight down your arm to your heart...and it can potentially stop your heart / kill. Lucky. Stay safe sir 🙏 It's good ur safe and alive to tell about this unacceptable voltage leak...by just touching it some exterior screws. Maybe isolate those screws or put non conductive covers/ caps on em. Maybe some non-conductive shielding or farad wrap shielding installed by manufacturer would make it safer. Portable systems... need to remember...need to be grounded to the Earth or to a an AC ground wire ( not chassis vehicle ground). Keep safe.
It was grounded actually. Doesn't prevent leakage from MPPT circuit that's at higher potential than inverter output. Also I'm finding difference of potential between expansion battery and main unit without PV connected and ground connected with AC input. So it has problems
The 10 meg ohm input impedance of your voltmeter tells you the open circuit potential, but not the available current. It takes only a few microamps to create a harmless but alarming shock sensation. I urge you to test again with something like a 1 kilo ohm 1/4 watt resistor across the input of your voltmeter. That will essentially turn it into an ammeter that reads 1 volt per milliamp. If the leakage current is only a few microamps to a milliamp or so, I would not regard that as dangerous. My suspicion is that the MPPT converter in the unit is capacitively coupling its high voltage, high frequency switching waveform to the chassis. This is a common issue because the power switching devices are screwed to a heatsink of some kind and that can act as an antenna that couples the rapidly changing voltage on the switching devices to nearby chassis parts. Only a tiny trickle through the air - but enough to measure and feel, especially if you panel string is high voltage. Were your panel frames grounded? Was either the positive or negative lead of the high voltage DC grounded? The Hysolis units - were they grounded in any way? On rubber wheels, with no AC mains connection, I suspect not. Maybe all that is needed to make sure the units can't have voltage on the outside it a bit of grounding, somewhere....
This is what I was thinking but you said it better. You can measure high floating voltages with lots of electronic devices. But if Will was able to feel the shock as something greater than static, that would indicate more current than I was thinking. I would love to investigate this further.
Exactly what me and my friend were thinking about the mppt. And I should test the amperage. Smart idea with the resistor. I'll have to test that carefully tomorrow. Good idea I just connected AC input to grid without solar a few minutes ago, getting 58 volts AC between expansion battery and main unit on the non-faulty one. So one has leakage from MPPT circuit like you mentioned, and would make sense, and other one has something else going on.
All the panels are grounded because they are laying on the concrete slab and it's wet. Even when dry I measure some leakage from them. I actually connect those arrays to an isolated input on a victron for this reason. I have measured the leakage across my concrete slab multiple times. One time I had a solar panel that was leaking a lot of current and it was causing a buzzing on the ground array frame. That was fun to figure out. With another array connected I had less voltage but it was still present. I also checked the wires and installation and connections first.
Oh good point about the heat sink that's very true. My friend has a device for finding these issues. We are going to try to hook it up and see where it sparks.
The hysolis is on rubber wheel platform. In the first thing I disconnected was the AC input to see if it persisted. Because I knew that would be a solid ground connection and the leakage to the concrete it would travel through.
Brilliant video. LOVE the response from Hysolis. Wishing them all the best in sorting this. Please do keep us updated on how it goes. I'm also super excited to put this in the off-grid home I'm planning.
I have come so close to purchasing this unit but I kept putting it off until I could see your review. I am so thankful I waited but man am I disappointed! It is so unfortunate to have such an amazing unit that checks all the box and to have such a major failure. Thanks for your review and I really hope Hysolis gets this issue figured out.
Same here. I thought I was satisfied with my current setup, but this once had my wallet preparing to argue with me... But my hype quickly vanished when safety became an issue. I really hope they sort these issues out.
Wow. Sorry you were shocked, but glad it wasn’t worse. Hopefully they will fix the issue and improve their quality control processes so this doesn’t happen again!
EcoFlow Delta 2 now has a “lab feature” that turns the AC inverter on automatically if it turns off due to a drained battery, then turns on automatically when solar input is available again.
Love your videos Will. This one especially. After viewing your video and reading the comments below I realized I didn't have a clear understanding of phantom or ghost voltages. Upon researching this I learned my Fluke 117 has a loZ setting for measuring this exact thing. Actually, i knew the setting was there but didn't understand what it was for. RUclips has a couple of good explainer videos for the Fluke 117 AutoV LoZ. Once again you have expanded my knowledge! Thanks Will.
Careful Will! Safety should consist of multiple layers, any one of which is enough to protect you. One layer of safety is never enough, even if it's a strong layer.
I completely expected there to be issues, to many great features, and you my friend are their trouble shooter. I'm very glad you were cautious, we need you around and healthy to continue making your videos 😄
Will Prowse saves lives!! Thanks, Will! A new guy like me, dying for a system like this, would not have caught that. I hope they get back to you with one that is fixed, I would still be interested.
PV array is grounded fine and there is a different array connected. Also, getting difference of potential right now without PV connected at all. See my community post. it's not my array, and that was the first thing I checked. And it should be isolated regardless
The newly announced Bluetti EP900 goes up to 9000w of solar with a solar voltage of 500v input. It was pretty cool to see at CES! I hope you get to test that one as well!
@@WillProwse I had a chance to meet with some engineers from EcoFlow and I am super impressed with what's in thier pipeline. I'm sure Bluetti is also working on some great stuff but they do need to improve their customer support!! I was hoping to run into you while I was down there since you live in Vegas! haha Maybe next year!
Very pretty casing. Looks so sci-fi. Shame about the current leak though. Having said that my Mpp Solar inverter had the same problem till I used a true earth ground.
An unbelievable product, one shipped to a customer with a potenial to kill. How did this product pass the required government tests? As a retired engineer, I learned early about the principle of first do no harm. Incredible. Will, may you live long and prosper. Bill
Now we're talking. Finally something that saves people the unnecessary hassle. I've been waiting for something like this. Sorry you were put in a dangerous position man.. I hope that company can get it together.
Wow, that's disappointing, iknow how excited you and minute man prep were.. Hopefully they will make the necessary changes. It has a lot of great potential...
Good job on giving the straight info - I'm sure they'll fix it, but that sort of issue shouldn't have made it through for an adequately tested product. Imagine if a Victron unit had done that - you'd be livid!
I think I'll stick to my ecoflow delta pro 3600 with an extra battery. The unit you showed in video sounded so good until you say you got shocked by it. Take care Sparky. Love these videos you do. Dean 🇬🇧 🙏
I've seen this exact thing before in a tiny solar system I made using an APC SmartUPS. Solution there was to tie the battery negative to the AC ground of the output.
used to watch you prehoax seems like you've come a long way much bigger systems. Still the same will though glad you're still making vids. You can do anything you want to in life
I am SOOOO happy you are alright. I did ***NOT*** want to read that you had been injured by one of your testing subjects. At the beginning of the video I too was VERY excited about the stats on this device. Too bad about it being deadly.... jeez.
Great Video! Thanks Will. Maybe make a separate caution video explaining what you said at the end. We get excited to try something new, and trust that the products are going to be great. So we let our guard down and that can lead to accidents. You made a great point about that. Perhaps that warrants a video all on its own, a cautionary tale. Every system that can produce 120v AC has the potential to injure or kill someone. So even a 12v system, from the inverter on the 120v ac side has that potential. You are great at explaining these complex issues in a way that is easy to understand. Would be a great safety video for beginners who are excited about building their new systems. Thank you for all you do! -J
good video Will. as a reminder, even experts can get caught. as someone who works with HV power supplies, transmitters and amplifiers, we sometimes get complacent. all it takes is some sort of resistance to 'elevate' ground and now you're dealing with a hot case. Great reminder.
you are really good at catching something like this kinda sounds like a floating neutral not sure but u do an amazing job kudos to you . what u discovered most likely saved someone from a nasty shock or worse.
I am SO GLAD that you honestly reviewed the dangers of this Apollo5k, as I was thinking it to be superior to the Titan and now I wonder if they have corrected the problem by now…otherwise the Titan is still the way to go…
I cannot wait to hear the feedback from the manufacturer ASAP. I guess you will be adding another safety test step on your next review. You may want to have leakage tester for your lab.
Hey man, thanks for all of your informative vids. I really enjoy them. Also I am glad that you weren't injured when you got lit up. A few more volts and amps and fire would have been coming from your eyes. Joking! Please stay safe, I truly like your vids and advice.
Wow. Speechless. Like you said, Will, these look great. They look premium; they have premium features. They get your guard down, and then ZAP! Thanks for what you do! Stay safe!
Will just discovered the importance of case earth bonding in high voltage power systems. This is part of a reason why all AC mains powered metal cased appliances have a ground pin on the AC plug.
If one company does something, then others cant be too far behind. I imagine this company will likely fix whatever leakage there is, but also companies like bluetti and jackery cant be too far behind.
Thanks Will, brilliant system, unfortunately there is a problem, this will happen, to recover from it is the most important thing. The manufacturer has come to the party, this is impressive.
That’s crazy.. Deadly shockingly Crazy? Dang Will, you had me excited about this unit. It’s Super Easy to advertise these features.. and not to dang difficult to design in these basic features and functions? It’s Not Rocket Surgery! It blows me away that this thing got out the door? Function testing? Nope QA testing? Nope Safety testing? Nope Glad you are still kicking Will. Peace Prospector Tripp
Hi Will , I follow you for several years even though my English is just fair, but know nothing about electricity. I learned a lot from your videos . I was concerned about you lying your arms on this device, and coincidentally just happened., I was going to call your attention on this matters since this kit looks metalíc in the outside. Hope they fix the problem cause I been looking for a kit like this , not just for emergency’s but to have permanently hooked off grid,.. happy New Year and again big thanks.
That's terrifying. Watching the start I went down into the description to find a link to this unit and when I didn't find it I looked at the title and thought "hmm... I should keep watching to the bad stuff" and wow... you weren't kidding. Dangerous may be an understatement. "Deadly" seems more apt.
Equipment standing, rolling, or sitting on a rack should be grounded before you test anything. Check that new equipment is properly grounded to the case and connected to the building ground. Also, check leakage to the building ground with the power on and off. Stay safe, guys.
Wow, nice looking units, but I agree with your testing... It could potentially literally " shock the living s*** out of you. One of these units would run my camper for a hell of a long time... With a touch of solar to recharge... Would like to see a secondary review from your channel, as you continue testing this beast...
Hey Will, big fan of the channel and been around on several youtube accounts for awhile. Interestingly enough, I had the same ground leakage issue on one of the eg4 6500ex inverters. It was eventually warrantied and I have a new one that works. In fact it's flawless. First one shocked me when I would lay my forearm across it or touch certain areas. I thought for sure I did something wrong... but my electrician (commercial electrician) and I verified everything was fine. We couldn't figure out why there was voltage potential across different parts of the body of the inverter. Super scary.
I'm a huge fan of eg4 and respect them 110% but perhaps there needs to be some standard operating procedures / standard installation procedures / standard user safety procedures because inverters are becoming more and more dangerous with the increased PV voltage IMO. It's necessary but safety blatantly falling behind in these Chinese circuits.
@@WillProwse At the time, I was using 6 Trina Solar TSM-250PA05 in series. I was upgrading from the LVM-es 3000 growatt that has the 250 VOC limit. When I was testing the unit, the panels were on the ground outside on a large concrete slab similar to how you've set some up in the past. Decided on that since it was quick and easy to check connections without having to climb all over my roof or ground mount array. Regardless, I thought I was crazy. Actually had no Idea that this was an issue on inverter circuits until I went around the forums. I was measuring all kinds of weird potentials. Like probes on the case of the unit a few inches away from each other was 15-20 volts and other places it was 50. This was back in June 2022 and I know some revisions were made to the units since and my current one is great, except it has the error 61 issue. Thankfully, I'm using DIY LiFePO4 cells so it's a non-issue for me.
I was shocked! Well technically you were shocked, but I couldn't believe it! How they would let it roll out like that. I'm curious if it has a UL sticker on it. Also curious if the addition of that removable ground point could have had a hand in this?
you are so right. Turn on when solar available. Ecoflow is so expensive and they dont have it and dont have notifications, they dont have api or any smart house integration.

Very pretty casing. Looks so sci-fi. Shame about the current leak though. Having said that my Mpp Solar inverter had the same problem till I used a true earth ground.
Stay safe. Thanks for the video
You put your life for us sir. That is oustanding.
An unbelievable product, one shipped to a customer with a potenial to kill. How did this product pass the required government tests?
As a retired engineer, I learned early about the principle of first do no harm.
Incredible. Will, may you live long and prosper. Bill
Next video title "Houston we have a problem" :-) Glad you didn't get injured, and thanks for all you do for this community.
Thanks for the helpful videos I live in Las Vegas and I am just getting into solar for off grid application
Thanks for the info brother . Maybe the competition will catch-up. Minus the shock.
I am glad you are putting this stuff out there .
Wow I'm glad you're okay.
I'm glad you're OK!
Now we're talking. Finally something that saves people the unnecessary hassle. I've been waiting for something like this. Sorry you were put in a dangerous position man.. I hope that company can get it together.
Wow, that's disappointing, iknow how excited you and minute man prep were.. Hopefully they will make the necessary changes. It has a lot of great potential...
Good job on giving the straight info - I'm sure they'll fix it, but that sort of issue shouldn't have made it through for an adequately tested product. Imagine if a Victron unit had done that - you'd be livid!
I think I'll stick to my ecoflow delta pro 3600 with an extra battery. The unit you showed in video sounded so good until you say you got shocked by it. Take care Sparky. Love these videos you do.
Dean 🇬🇧 🙏
Thanks for the review and be safe.
I've seen this exact thing before in a tiny solar system I made using an APC SmartUPS. Solution there was to tie the battery negative to the AC ground of the output.
used to watch you prehoax seems like you've come a long way much bigger systems. Still the same will though glad you're still making vids. You can do anything you want to in life
glad your ok man
Thanks for doing what you do help everyone. Stay safe.
I am SOOOO happy you are alright.
I did ***NOT*** want to read that you had been injured by one of your testing subjects.
At the beginning of the video I too was VERY excited about the stats on this device.
Too bad about it being deadly.... jeez.
Great Video! Thanks Will. Maybe make a separate caution video explaining what you said at the end. We get excited to try something new, and trust that the products are going to be great. So we let our guard down and that can lead to accidents. You made a great point about that. Perhaps that warrants a video all on its own, a cautionary tale. Every system that can produce 120v AC has the potential to injure or kill someone. So even a 12v system, from the inverter on the 120v ac side has that potential. You are great at explaining these complex issues in a way that is easy to understand. Would be a great safety video for beginners who are excited about building their new systems.
Thank you for all you do!

Looks like this it has a lot of potential.
....in more ways than one.
You are doing such great videos! And this might be one of the best. You might have realy saved someone or kid from getting hurt.
Thank you for being the test dummy!! You likely saved many lives!!!
good video Will. as a reminder, even experts can get caught. as someone who works with HV power supplies, transmitters and amplifiers, we sometimes get complacent. all it takes is some sort of resistance to 'elevate' ground and now you're dealing with a hot case. Great reminder.
Will, thank you for doing what you do. You're a fantastic resource. Stay safe!
Another nice and informative video Will.
It was looking "the goods" there for a while. Cheers.
Wow! Glad your safe! 🖖
Wow glad you're safe. That's kind of scary.
you are really good at catching something like this kinda sounds like a floating neutral not sure but u do an amazing job kudos to you . what u discovered most likely saved someone from a nasty shock or worse.
Holy Hanson @ getting shocked. That's bananas!! Sheesh. Such a powerful unit to have that kinda issue.
Thanks again Will for another Life Saving video.... Cheers 😁
Will please keep us posted about the issue . unit looks great with tons of futures ,hope the will fix it.
When Lake Mead runs dry and Hoover Dam's generators come to a stop, Will Prowse can supply the city of Las Vegas with all the power it needs.
I am SO GLAD that you honestly reviewed the dangers of this Apollo5k, as I was thinking it to be superior to the Titan and now I wonder if they have corrected the problem by now…otherwise the Titan is still the way to go…
Damn!... We were Almost there with what we are all looking for. I was about to put my Eco Flo Delta Pro on hold.
This is a game changer. Wow, I watched to the end after I posted and was surprised to see the conclusion. Needs some improvement after all.
I cannot wait to hear the feedback from the manufacturer ASAP. I guess you will be adding another safety test step on your next review. You may want to have leakage tester for your lab.
Hey man, thanks for all of your informative vids. I really enjoy them. Also I am glad that you weren't injured when you got lit up. A few more volts and amps and fire would have been coming from your eyes. Joking! Please stay safe, I truly like your vids and advice.
Wow. Speechless.
Like you said, Will, these look great. They look premium; they have premium features. They get your guard down, and then ZAP!
Thanks for what you do! Stay safe!
These things just look dead sexy - like mid-century electronic test equipment.
They remind me of the old Heathkit Ham Radio Equipment from the 1970's, which I own a few.
Apollo lunar capsule ?
@@DIYSolarEnergy This. Or that one Mac workstation from the 2000s.
Exactly. This is fallout shelter gold.
It just needs a big honkin' dial gauge like an old battery charger. Red means low.
Will just discovered the importance of case earth bonding in high voltage power systems. This is part of a reason why all AC mains powered metal cased appliances have a ground pin on the AC plug.
Will may have saved some lives. Thank you!!
Crazy that a company would ship an potentially lethal product with so little testing.
Glad you managed not to get hurt Will
Outstanding job, Will. Integrity matters.
Wow, this product review was shocking!
But seriously … great job! Thanks for all your hard work!
If one company does something, then others cant be too far behind. I imagine this company will likely fix whatever leakage there is, but also companies like bluetti and jackery cant be too far behind.
Thanks Will, brilliant system, unfortunately there is a problem, this will happen, to recover from it is the most important thing. The manufacturer has come to the party, this is impressive.
That’s crazy.. Deadly shockingly Crazy?
Dang Will, you had me excited about this unit.
It’s Super Easy to advertise these features.. and not to dang difficult to design in these basic features and functions?
It’s Not Rocket Surgery!
It blows me away that this thing got out the door?
Function testing? Nope
QA testing? Nope
Safety testing? Nope
Glad you are still kicking Will.
Peace Prospector Tripp
They were doing good!
Hi Will , I follow you for several years even though my English is just fair, but know nothing about electricity. I learned a lot from your videos . I was concerned about you lying your arms on this device, and coincidentally just happened., I was going to call your attention on this matters since this kit looks metalíc in the outside. Hope they fix the problem cause I been looking for a kit like this , not just for emergency’s but to have permanently hooked off grid,.. happy New Year and again big thanks.
yeah i sure hope will isn't vaxed, because it's all like "Static causes sudden death. Doctors baffled."
That's terrifying. Watching the start I went down into the description to find a link to this unit and when I didn't find it I looked at the title and thought "hmm... I should keep watching to the bad stuff" and wow... you weren't kidding. Dangerous may be an understatement. "Deadly" seems more apt.
Thank you for doing all your reviews
Wow. Good catch, Will!
I watched Min Man's vids on it. Guess I will wait until they fix these problems.
Stay smart Stay Safe
Equipment standing, rolling, or sitting on a rack should be grounded before you test anything. Check that new equipment is properly grounded to the case and connected to the building ground. Also, check leakage to the building ground with the power on and off. Stay safe, guys.
I AM GREATFUL TO GOD YOU ARE OK
Glad you're ok. The units are good looking tho. They remind me of the old PowerMacs!
Wow, nice looking units, but I agree with your testing... It could potentially literally " shock the living s*** out of you. One of these units would run my camper for a hell of a long time... With a touch of solar to recharge... Would like to see a secondary review from your channel, as you continue testing this beast...
Hey Will, big fan of the channel and been around on several youtube accounts for awhile.
Interestingly enough, I had the same ground leakage issue on one of the eg4 6500ex inverters. It was eventually warrantied and I have a new one that works. In fact it's flawless. First one shocked me when I would lay my forearm across it or touch certain areas. I thought for sure I did something wrong... but my electrician (commercial electrician) and I verified everything was fine. We couldn't figure out why there was voltage potential across different parts of the body of the inverter. Super scary.
I'm a huge fan of eg4 and respect them 110% but perhaps there needs to be some standard operating procedures / standard installation procedures / standard user safety procedures because inverters are becoming more and more dangerous with the increased PV voltage IMO. It's necessary but safety blatantly falling behind in these Chinese circuits.
No way!!! That's Awful :( what is your PV array configuration? What kind of solar panels?
And yes I agree
@@WillProwse At the time, I was using 6 Trina Solar TSM-250PA05 in series. I was upgrading from the LVM-es 3000 growatt that has the 250 VOC limit. When I was testing the unit, the panels were on the ground outside on a large concrete slab similar to how you've set some up in the past. Decided on that since it was quick and easy to check connections without having to climb all over my roof or ground mount array.
Regardless, I thought I was crazy. Actually had no Idea that this was an issue on inverter circuits until I went around the forums. I was measuring all kinds of weird potentials. Like probes on the case of the unit a few inches away from each other was 15-20 volts and other places it was 50. This was back in June 2022 and I know some revisions were made to the units since and my current one is great, except it has the error 61 issue. Thankfully, I'm using DIY LiFePO4 cells so it's a non-issue for me.
I was shocked! Well technically you were shocked, but I couldn't believe it! How they would let it roll out like that. I'm curious if it has a UL sticker on it. Also curious if the addition of that removable ground point could have had a hand in this?
Please do a follow-up vid when you get some resolution from the mfg. I'm sure they won't let this lie and future units will fix the ground faults.
you are so right. Turn on when solar available. Ecoflow is so expensive and they dont have it and dont have notifications, they dont have api or any smart house integration.
