This is why I'm going with my spare Nissan Leaf battery. It's already a high quality, tested, sealed design with specific BMS designed for it inside. So much safer in the resepect you don't even have to open up the sealed, waterproof casing. Risk is reduced then to just the main lead contact...

Hi. They can now thanks to the work being done over on Dala's EV discord channel. So far they have quite a few working brands and models listed on their wiki page where they connect car EV battery packs with great success. The cost is very low for the kWh provided by these large battery packs...

:) Haha. Kinda. Trying to get free battery packs. With these inverters you can connect up reclaimed EV batteries from cars. Big packs. Without having to take the pack apart and reassemble it at all. Just leave it in it's housing as is and connect it up. Much safer and already tested and working...

Thanks. Yeah, I am planning on hooking up the spare Nissan Leaf battery I just took out of my leaf when I upgraded it to a 30kWh pack a month or so ago. So I have 24kWh just sitting around unused right now. With Dala's battery emulator the cost to benefit ratio is incredible when reusing these...

Thanks. Will do. Also, I should have titled it 500v inverters and not only up to 400v. Is changing the tread title allowed here and without issue do you know? Oh, and by the way, we signed with a solar installer for putting up the panels on the main house. So my other lab location is where...

Yes. Check out the battery-emulator by Dala. Open source. It lets you connect up EV car battery packs to inverters that support HV storage batteries higher than 48v. Like 400v Nissan Leaf car battery packs. Info here: https://github.com/dalathegreat/Battery-Emulator Supported inverter models...

Thanks again for all the great advice. DDP is out it seems. Sadly he is saying, "Today, the logistics department informed me again that all duty-free transportation channels to Japan have been stopped. So we can only provide air freight DDU for inverters or CIF for the whole system to the...

Haha. Yep. :) Good thing the car makers already designed and included a robust BMS inside their packs. This makes it SO much easier and more reliable. As well as safe in not having to open up the packs. This is the way to go.

I was thinking of doing that but was just going to wing it. I'll now go visit them and see what we learn before ordering. At least we won't get sticker shock if the customs duties are way higher than expected upon arrival. I've heard that Japan really wants to increase solar though throughout...

Yeah, I remember that incident. Terrible stuff. Oki changed after that. Wished that had never happened and Oki had remained like it was before then... So we called the customs office yesterday. They said there's no problem on importing solar panels and parts. Tax is likely going to be 10% or...

This is actually really good scoop. Thank you. I'm going to find a good 00 fuse disconnector but load it up with some 000 fuses as they go a bit lower on the amperage. I could only find 00 fuses starting at 100A and I want 50A fuses for my setup's battery pack. As the Solis S6 11.4k is rated...

Thanks for that Daddy. But at my current experience level with making my own battery packs, which is zero, I'm thinking that is where the risk for me getting electrocuted would be highest especially with HV battery builds. Even Solar Guppy mentioned HV battery builds are challenging even for...

T Thank you Daddy. The world makes sense again now. Wow. Japan... as usual has to be different. Well, like France too I guess. lol. Thanks for that amazing nugget. I doubt many know about this hidden info.

Thanks Daddy. I took the option for sea shipping today. You were right. Air was not worth it. I just placed the order for qty 26 of these. $767 for the cells and $542 for sea DDP shipping. And a $48 surcharge by alibaba for the transaction. So $1348 total. I hope that's reasonable. $29.50 per...

There we go. Now that's the kind of formula that makes perfect sense and is simple to follow. Thank you. I wished someone had shared that earlier but glad you did for me. That's so simple! One question to make sure though. You say, "regular expected usage". Shouldn't I put that at the max...

I hope to get back to my little project here this weekend again finally. Anyone else looking into an HV inverter and battery setup too next? I will start a build thread this weekend and link it here as well. Already made an unboxing video but have yet to power it up to check it as yet.

Hey Daddy, Thanks for the reply. I've been reading a few of your posts in other threads and love your straight shooter stance. We think very much alike. I look forward to talking more about Japan with you when we can. I'm in Okinawa. Been here since '88. Saw the decline coming to the states way...

Thanks guys. Appreciate the replies. @SeaGal Thanks for that. How do you like your Solis? How's the app quality and reliability? Good company? Good support? No issues overall? Dala's 'battery-emulator' is able to fake being a supported battery. The Solis is on his list so it seems at least...

Well, we've got a typhoon about to hit us by Saturday. Took today off to prepare our and the in-laws house for it. Long day. We also met again this morning with the solar installer we like the best. He's proactively created a new panel layout for us with 38 panels now as an option. So 445w x 38...

Thanks for that input. Based on that input, I have a couple more questions and some more clarification details if it helps: So I am having an electrician come out in the next week or two to install a manual transfer switch (between the meter/grid and main breaker panel) as well as upgrade the...

Thanks DT. Sounds like I should probably stay away from an EU and 3 phase inverters for now based on my limited knowledge and experience. For my main house I'm thinking I may just go with a SRNE Japan certified 48v 12k unit. One each for our duplex. That way I'm in spec and can be safer at the...

Okay guys. I've heard of these and liked them when I first saw them 6 months ago. Wanted one ever since. But I need a minute and perhaps a bit more info to grasp how I need to wire this up based on the above work my electrician is about to do. Doesn't look like I can easily move my current...

Looks like I just had to edit the first post. Thanks mang.

Thanks for the push back on this Solar Guppy. He's only continued to state that they have a relationship with Solis and all will be smooth. Yet on the battery compatibility list he sent me Solis is not yet listed on the HV section. I've pushed back and stated that I will order the Solis S6...

Wow! This is great info! Okay. Looking it over carefully now to grasp it. Thank you.

Hey. Did you ever get this figured out? If so, how did you end up doing it?

Will do! I'm reading your build thread from page 1 now. We're a lot alike I see. Love the detailed documentation and evolution over time also well documented. Very helpful. I will learn a lot here I can tell. Also, I was originally going to go with those XW Pros as well as I saw this one guy...

Yep. For most regions nowadays that's true. In Japan at least for now they allow unlimited sell back at 16 yen /kWh. Locked in for 10 years from the time of sigh up, then 8 yen/kWh for the following 10 years. So some people who are personally into solar set up a ton of panels and make money...

https://www.patreon.com/dala https://github.com/dalathegreat https://www.youtube.com/@DalasEVRepair/videos He has a discord group as well that I'm in where they answer direct questions in real time. Great group! https://discord.gg/HZFMfw8b I just realized though that you may have taken your...

Very interesting times back then to have to do that I bet! :) It's nice to see battery technology finally progressing a bit. But I sense it's being held back a lot from what it could be. Update on the alibaba quotation. His email quote came back at $1514 delivered with $747 of that being air...

I'm getting pretty excited by these Seplos Hitens 409v packs. Great find! I am ordering my first S6 as a test with a Nissan Leaf 24kWh pack and Dala's battery emulator software. As I only paid $500 bucks for the whole car and upgraded the pack to a 30kWh pack for $700. So I have this extra pack...

Still doing my due diligence daily.

Hey OffGridForGood. Liking your posts. I've not read to the end of this thread all the way yet, but I've been in search of, "Are there any single phase 240V (60hz) high voltage inverters on the market at this point in time?", for a few months now. Well, for me 100v 60hz as I'm in Japan. So far...

Daddy, Great question. There are so many I don't even know to ask yet. I don't know what I don't know yet still. Hence... I think I should take Solar Guppy's advice here and follow his known good equipment selection in choosing the Seplos packs he is using. Frustration has a high cost. I've...

Yep. Exactly as I suspected. Well, I've at least now proven it via real world direct testing. Heh. Appreciate the confirmation. I'll play with them a tad more and then recycle them. Thanks again.

Yep. And I'm in talks with Seplos about getting their S4 stack(s), and was just told this: So there's that too. But impressive she checked proactively with Solis directly without my prompting. So that's quality right there. She's searching for other brands now. Not so sure there are any that...

Did you order the SRNE 12k from Borick after all?

5 boxes being prepped for me now. 26 cells. Well, their communications so far have been excellent. Even better than the highly touted docanpower salesgirl, who I was not nearly as impressed with on the two occassions I emailed her. These guys are asking good questions and sending precise...

Hey MyK3y. You beat me to the punch. Nice! Glad to see others singing our tune. Are you on Dala's discord channel? I picked up a 30kWh Leaf pack for $600 delivered here in Japan a month or two ago and swapped it into my newly aquired 2014 Nissan leaf. Was a super easy conversion as I didn't...

Sounds good. Things are becoming clearer now based on this excellent input. Thank you guys. So next question. Do I also use a breaker of equivalent rating in line in addition to the fuse? E.g. the fuse goes very close to the battery to stop potential runaway voltage, right? But placed in a...

OMG. They just left. Spent 3 hours with us. Nice guys. But they want like $80,000 dollars to do both floors of our duplex. With only 14kwh batteries per floor and an 8kwh inverter per floor. No English menus and I can't adjust anything. No. Has a nice Nichicon $8000 V2H unit though... lol

Thanks man. I'm also trying to determine who makes the Enetelus Eibis 7 line of inverters and batteries. This is what they're offering me as options. https://www.enetelus.jp/products/eibs7.html And lastly Delta inverters. Which are the only ones they say have English menu options here in...

Thanks. What do recycler's pay these days in your areas?

Thank you. Appreciate the concise, accurate answers. Do you have a recommendation on which to choose between the Tigo and APC? Thought I might buy Tigo monitors someday for the panels perhaps. But also heard some have caught on fire? Lastly, any sourcing recommendations? I'm in Japan so don't...

Smart. Considering the price of these is so cheap in comparison to a lot of others, I think you have chosen an excellent path. You're much further ahead of most with these choices it seems. Thanks for the quality input as always. I will do the same then. Also helps if these go out of...

That's also what I was thinking and so asked. But I think it will cut through so fast it won't heat up much. I also only found bolt cutters. What are the specialist ones you're mentioning?

Interesting. We had a guy pick up the 6 we removed from the ECOMS mini EV. He only paid 50 cents per battery to take them away... I'm not looking forward to moving 20 of these tomorrow, trying to make space for them only to have to move them again to a recycler for 50cents each. Hmmm...

Found a possible new contender in addition to the Seplos Hitens. SunPal sent me this info today: ECO-H SERIES STACKED LITHIUM BATTERY: 192V 50Ah 9.6KWh：USD1960/PC 288V 50Ah 14.4KWh: USD2651/PC 384V 50Ah 19.2KWh: USD3343/PC 480V 50Ah 24KWh: USD4035/PC "Including high-voltage BMS controller +...

Whoops. Yes. It's late here. Thank you. This is what I came up with if I use 8 panels per string. So it looks to be within the limits of the Solis S6 I believe if I'm reading the spec sheet correctly.

Apologies. Didn't see your response here above immediately after DT's until just now. It makes more sense to me now why you replied that you were not going to give further input now. I see I missed the above and my response came across without factoring in your above response. I'll do...

Thank you again perfu for this wonderful, detailed input. So about these "industrial blade fuse holders", I'm interested. Couple of questions: 1. Would these replace T-fuses? In addition to? a. What is the optimal placement and quantity in the system? 2. How do I select the correct size...

Later Edit: Well, I just measured the incoming line from the pole at the main breaker. It's not 200v after all. It's 102v. I could have sworn it was 200v from when I measured it several years ago. Guess not... So that is the answer right there. This is only one leg from the pole feeding this...

I plan to have someone install the panels on our main house. But perhaps that is the reason why it's not used for residential homes? We had some solar companies visit this week and they are recommending smaller panels by QCELLS. The Q.Tron M-G2.4+ which are only 430W panels at 21.2kg. But they...

I just bought the 24s 15p as I don't need the inverter either for my project mini EV. I like the idea of having the 2A active balancing capability. I'll try the newer JK BMS model for inverters someday though when I'm in need of that to talk to my future inverter. For now this is best for me...

Thank you for your kind reply explaining further peufeu. Okay, I kinda thought I circled the wrong thing in the second spec sheet when I circled 100Ah and not the 'recommended 50A' above it to the right on the chart. But didn't want to post again should it confuse things further. I was also...

You are right yet again man. :) I talked with two different solar salesmen and they both confirmed the Delta, Enetelus and XSOL inverters will power 200v air conditioners. So they just don't call them split phase here. They call them single phase. Even though they are 100v/200v output AC. Good...

Thanks everyone for the input. Grateful. I'm still researching hard as I want to place an order for an inverter on the 1st of August if I can find the best brand/model to buy. I plan to install a Leaf battery pack so will need to use an inverter that supports HV battery packs of up to 400v...

Thanks for that great detail. Very good to know. Do you have a Solis S6 11.4k? How are you liking it? I finally ordered one this week. All paid. Should be here in 42 days they said. Our fourth solar company salesman visited yesterday and was saying that prior to three years ago they would...

So we got a call from the freight company yesterday saying they will be delivering the blade batteries this coming Monday. Aug 5th. So about 39 days total? They'd said it would take about 30 days. So I guess that's typical. I'll share pics and readings from the cells when I receive them...

I'll try yes. Thanks for the interest. It might help many. For now if anyone wants to join Dala's discord channel I've shared all my steps there when I did them. I'd share the link if I knew how. But just search for it and you'll find it I'm sure. Mostly because he is the one who open...

Hey guys. First post. I'm rebuilding a used Toyota COMS (ToyoBody) EV. Upgrading the 6 lead acid batteries to lithium. 72v system. Looking at a JK-B2A24S20P BMS. That a good one? Anyway, so far I think the EVE 100ah 3.2v LF100LA cells may be a good bet to replace the six dead Panasonic...

Hey SolarGuppy. I reached out to the power store. No answer. Followed up again today. Let's see if they reply. Also, just noticed that Seplos has a newly revised version of the Hitens now. Seems they are going for a slightly taller design and the cost per kWh is a bit better at $2900 for...

Thanks guys. I've added the spec sheets for the two inverters I've found so far to the top post here for future reference. This might helps others also searching.

Hey guys, Not sure where to put this. Mods, please move as appropriate. So we have five vendors visiting this week to give us proposals for a total system install to include panels, inverter, batteries, and even V2H options. I wanted to share a few worksheets one of the vendors provided for...

Oh, interesting. My sunpal guy just told me he has another model of the ECO-H than the one I originally listed above. But this time a 256v model. But still 25.6kWh... It's called the ECO 25.6H-X1. Hmmm. How does that even work? Is that possible? How do they make it half the voltage but still...

Hi guys, Is there a way to connect my new inverter to the grid but guarantee the power company will not see any back feeding so they won't know it exists? Is there a device I can connect in between the grid and feed that would take small loads that the inverter might put back towards the grid...

I've still not had time or energy to unbox the new inverter yet. I've been repairing a new (to me) 2011 Mitsubishi i-miev EV electric car. Got it working last night! Test drove it tonight and it's so fun. My wife is going to love it. So it's back to the solar build this weekend. I'll unbox...

I'm glad you posted that. Because I've gotten quotes this week for Longi LR7-72HTDR-615M at $70 per panel from sunevo. And LR7-72HTDR-625M from sunpal for $78.50. But reading they are scammers? I'm a bit crushed as those prices seem excellent to me, right? Who sells these panels that is very...

Thank you so much for the safety tips! Could save a life. Mine for instance. So I'm grateful. I'll take all advice I can get. So you think I'm taking a big risk being a novice and working with HV? Can I get 25.6kWh packs like these in 48v for $2900 in a stacked configuration for my house? If...

Hey @Zwy . Interesting post you have here. First I've heard of this 'sync phasing' topic. Is this what is set when you choose your grid-tie region code in the settings of an inverter to make sure it 'matches' correctly? I ask, because I was perhaps mistakenly thinking I could connect any...

My Solis S6 11.4k-US has just arrived! Sooner than expected actually. Seplos has been way faster than they promised. That's nice. From my house 200v outlet I'm getting 102.6v between one hot and N. And 205.2v between the two hots. Is that enough to power it up I wonder? If so, and since you...

Hi guys, Second post. I'm in Japan (100v 60hz) and am researching the best inverter brand and model to buy for a DIY solar build. I intend to connect a Leaf 24kWh battery to it for home storage. I'm a member of Dala's EV discord group but have additional questions. So far I've been able to...

Also, reposting this question from another thread I'd asked this question in but didn't want to hijack the other member's thread so am posting here for input. Thank you guys. "Hey @Zwy . Interesting post you have here. First I've heard of this 'sync phasing' topic. Is this what is set when you...

Thanks. So you only power up your inverter from solar and/or battery?

Hi, So I'm considering these panels for home use here in Japan: LR7-72HTDR 600~625M https://static.longi.com/LR_7_72_HTDR_600_625_M_30_30_and_15_Frame_20240527_V2_9cb60497fe.pdf I don't see anyone here really talking about 600+ volt panels. Why? Why is the US and/or residential not using these...

Oh, that makes sense now that I think about it. The original specs for the ECOMS said it was rated for 50 kilometer range with a top speed of 60 kph. So if 4x of that perhaps around 200km? But they would weigh 150lbs less or so I believe. So a full person less in weight carried. So perhaps even...

Hey Perfu, Thanks again for all your high quality input. Where did you order your blade fuse holders and fuses from? I'm about to order and looking for specific suppliers and if you have the brand/model number on the ones you ordered to help me start off my search. In searching for the Apator...

Excellent scoop. Thank you. I'll just stay off grid with my DIY stuff for my garage workshop. Sounds like a lot less headache and I can upsize it as I need. Sounds like we both had the same original intent but fortunately I can leverage your experience being further down the path. I will then...

Thanks Daddy T. Also appreciated the two facetimes this week. It's been great meeting and talking with you. We're a lot alike and are on the same wavelength on this stuff for sure. I'm learning fast though and will be cautious both in the purchasing area as well as in setting things up upon...

From the grid. I ask because our new house (duplex) has a single incoming main 75A breaker feeding both houses. We have gas so don't use a lot of power I guess compared to others. We use about 600kWh per month per house on average. Just trying to grasp typical sizes required so was curious...

Sage advice. I hear it. Thank you. I will heed it and do some rethinking. Perhaps for my first system I should just go with 48v for the main house for safety of the house, the family and me. I will see what kind of quality brands/models I can choose in the 48v space and see what I can come up...

I looked into the EG4 6000XP and liked it. But It's off grid only I believe, right? Also I've heard reports they are a tad loud. Midnight solar the one is basically an EG4 18k but a bit better. I really like this one. But it's expensive as hell. And I read midnight solar was sold off? No idea...

But oh man... he just sent me the manual for these new batteries. They stack up to 10 battery modules for up to 51.2kWh of ESS in one vertical space. That's pretty impressive, right? I've not seen this offered elsewhere. Wow. I've attached the manual if anyone wants to look at it and see if...

I've posted the spec sheet and some other details in the first post of my thread on HV inverters here: https://diysolarforum.com/threads/inverters-that-support-high-voltage-400v-storage-batteries.85751/

Thank you. You are a great resource of information. I am learning some great stuff here. I really like the ability to connect a string to these so I can pull the fuse from a distance. No hands next to the arc! SO SMART! I could also close the fuse from a distance with a non-conductive pole as...

Hey guys. How are those of you who have bought this inverter liking it? I've contacted Borick and it seems this inverter is certified for use in Japan. So it might be one of my only options. Interested in opinions. You are able to grid tie it and sell back power no problem with it as well, right?

Oh.... just put ALL loads on the critical loads port of a hybrid inverter? Well, that's easy enough. Seems like a clean answer then. Thank you. Okay. I'd heard about the first part and even asked Solis support and they confirmed some small amount can go back to the grid. But the control loop...

Thanks again for the feedback on them. He's been pushing pretty hard and I think he's being sincere with me. But I'm also completely gullible at this point so wouldn't really know if he wasn't. He's now saying that it will be DDU and that I should pay via bank wire directly to them as if we...

Oh. Haha. Okay. No worries man. What's funny is that you are actually a very caring individual. I'm probably one of the few who know this because I've talked with you over facetime and can read the tone and timing. You just use 'tough love' here on the forum and those who didn't go through the...

Yep. same. Would love to connect with a few others on here as well via phone or facetime. It helps to have that additional realtime discussion and build rapport. Okay, I've just sent another ticket in to Solis Europe asking them if the Sunpal ECO-H X1 series is tested and compatible with the...

FYSA. I've been told by Borick on 9/21/24 when I asked again to make sure, that it's actually NOT CERTIFIED for grid-tie use here in Japan after all. But they have all the marketing materials in Japanese and even sell it on Amazon Japan. So it's just for off-grid use it seems after all sadly...

I was completely forgetting about this SRNE HESP48120U200-H inverter option of late as I was so interested in the HV Solis S6 11.4k-US. But the HV stuff might still be too early days for use here in Japan. The SRNE however I'm told is certified and quite popular here in Japan. So I'm going to...

I've been forgetting about the SRNE HESP48120U200-H 12k inverter option. Not HV, but certified and a popular brand here in Japan I hear. So will look at this closely this week. Got one of the five solar companies currently bidding on our house coming back tomorrow. I am going to hit him up with...

Funny you should mention them. I sent them an inquiry three days ago asking what model inverter they might have that would fit my needs. No reply back yet. Any recommendations? Currently I'm settling on the Solis S6 11.4k unless I'm wowed by some other alternative. I like the fact that sandi...

Solar Guppy. I can tell you're a wise man based on your choices in equipment selection and replies in the past for me already. I will at this point heed your sage advice. Hopefully that is enough for you to be willing to continue sharing at some point in the future. I appreciate you pointing...

Hey Solar Guppy, I'm about to pull the trigger on an S6 11.4k real soon if all is in order. Got a couple of questions for you if you don't mind. 1. How do you like it? Any major or minor issues? 2. Did you get it with the wifi dongle? Necessary? Works well? What about the Tigo option? Trying...
