Heres look inside.

Thanks all. That emporia looks like they got a 99 dollar jobber that just reads the main, as I don't need to break it down per breaker. Looks simple easy and has some good reviews. I will most likely go with that, assuming I like what I read. Thanks for the input!

Do you not know what "advance replacement" means? Are you purposely being obtuse?

So, I went ahead and ordered the NHX 12kw from Watts247. Should be here in a few days, I can probably do an unboxing video, but it will take me a bit to get it all set up, as I got a few things ahead of it and I move and work slowly.

Ahh I came back to revisit this, and I must have some how disabled updates, you guys all move faster than me. I have had 5 back surgeries and have chronic pain, nerve damage etc, I get about 30 minutes done a week if I am doing well that week. I finally getting some holes dug for the container...

So to put what I think is way I would do it, and you guys can tell me what I get wrong. I get grounding lugs on all panels, run copper grounding conductor from all 18 panels on container 2, through the conduit over to container 1, and earth ground the panels. Same for panels on container 1...

I hear ya. I am a bit younger at 44 this year. But I have had 5 back surgeries, multiple on the knee. I get about half an hour of work a week if I am lucky, if its cold maybe less. I do still need to track down the spds and fuses, I haven't picked any of that up yet. Got 8 holes to dig, I have...

I can't offer any opinions on what's enough. I want to go overkill in protecting my system, but also I need keep it simple plans, and I can't read schematics, they make 0 sense to my brain, but pictures like u posted, with labels showing actual wire going from where to where, I can understand...

Ruixu sent me this bus bar x2. I dont see it on their website though. They are big and beefy. I am sure it can handle the 4 batteries no issue, and I want room to expand to 6. Even with shipping my 2nd set of batteries I got 2 for the price of one ruixu.

I dunno if you got the answers you needed or moved on. But I live in a 40 ft reefer can, and I cool and heat it with a 9000btu 240v minisplit that draws like 15 amps at least in the manual. With a person and 2 cats, and fish, and a chihuahua, I have some insight. Humidiy, I picked up a 99...

Well, a simple looking at their spec sheet shows 6000xp max continuous output current 37.5 so this times 2 is greater than the 50 amps the 12000xp*(I was wrong, and TM corrected below, it's 25 amps output, so same 50 amps) can do. But then the 12000xp can handle more total solar or up to 28kw...

Nice. I am definitely thankful to all the people that blow their systems up, so hopefully I don't!

Good info. Mind posting what ferrules you used? I know you said not to, but I had planned on doing it, but they were straight ferrules like this, with a hex crimper. Or square. I hadn't actually decided, was planning it, and may hold off now that you have experience. Just wishing for more info...

There a little bit before I moved into it, some work in progress, shows the electrical, and I ran pex tubing in the floor.

Your system size and equipment is very similar to what I am planning to do. I have my panels already, but will be ordering batteries soon. I am trying to decide if I wait for the 12000xp or Gridboss 21, or order the NHX 12kw on watts247 page. The 10kw unit seemed to be quite the workhorse, and...

Definitely not to late, and thanks Oz, it is a considering factor for me. Whether I end up going with it or not.

I live in an insulated connex high cube. Why not install a mini split? I also have some midea u shapes for the mobile, I am slowly building my solar, everything I run so far is grid. Anyway, just a thought. I have a9k btu 220v midea mini split and it keeps me at 75 right above my pc station...

Any updates? Have you ran the inverter? How quiet is it? On sungoldpower site I think you can buy it with 10 year warranty but it stock has 5 year warranty.

Yep. But the net gain is lower humidity and temp where I want it. If I turn on a light, it also adds heat that the a/c has to remove. But then I can see. If I turn on my air fryer, it adds heat that my a/c has to remove, but then I can cook.

Right, I think, I got that too, that it can take up to 24kw of solar, but uses 21kw. So 21 is the usable amount of solar, as you can oversize a bit.

I have received the unit. Still, I have a multitude of things to get done before I can even get it mounted. Like, I probably won't even have my panels up until end of year, sometime next year. I have been buying parts as I save for them. Maybe I should start a full build thread in one of the...

First, 18kpv is 12kw of inverter so x2 is 24killowatt.

Well if you got 2 inverters, you would want bus bar that can do 600 amps. Is what I spitball mathed it. That's based on inverter I think pulling max or charging at max charging capacity. Fits in, with them having built in 300 amp surge protection. Batteries don't push their power, the inverter...

I haven't messed with the 18k, and only helped my neighbor with his system, I think i managed to fix some stuff, but take that I am less experienced than some of these guys. On his setup, we ran a 9kw inverter gasoline/propane generator by duromax xp9000ih. Now that generator, I wouldn't...

I run a 9k btu that is 13 amp 240v on my grid connected container. It does struggle sometimes in the summer to keep the temps at 76, but ti does do it. Winter, it has no issue. I live in rural AZ and it gets pretty scorching hot. Which is why I plan to do 12k btu unites. But still sticking to...

Look up arrowhead anchors. You can get em on Amazon if thats available where you live, or bullet anchors, they got a cable and a small end you pound into ground then when you pull back on cable it the head will turn sideways and they offer around 1000lbs per cabled arrowhead anchor. You can then...

And? Not to be pedantic, but it's a 3 year old thread, with updates over the years. You see those other updates, where people confirm it still works? I was just updating to let anyone finding this thread know that as of now, it doesn't work anymore. Thanks for the reply. Have a good day.

So, I have a tiny house with a 70 amp sub panel. Electrician did the wiring, took a 50 amp rv and had extra room and ran 70 amp to the tiny home. Will this let me separate my monthly electricity usage so I can isolate how much the tiny home is using, to better plan the rest of my offgrid build...

Somewhere when I was looking this up said 80 degrees. So I think that's the same as your 10 degrees. Just counting from the other side. To me 10 is 10 up for being horizontal, where as 80 is to leaning away from 90 vertical.

Yes. Gfci outlets. I Also found out gen wasn'tgrounded but called for it, so gen got grounded as it has a connection to go to grounding rod and so my neighbor just put that in. signaturesolar is sending us firmware update cable and going walk through everything, ours is has older...

Looked like it was the led light on the impact driver he was using to unscrew and screw everything. As for what's wrong, is it that he ran positive and negative from battery on one end vs positive from left most battery and negative from right most? I haven't wired my batteries yet, and they...

Do you think 2 inverters and 4 of those batteries could fit in a 5x10 building? What size is your building? Your shed looks almost like what I was planning before but I changed my mind. I also have 2 of those ruixu batteries. But I also have 2 of the ones I ordered off Alibaba. I have some...

uh didn't mean reply a blank reply.

So, for offgrid only, assuming i only need 1 12k inverter, solar and battery only, whats the better option between 12000xp and flexboss? Seems like with battery only they are both very similar.

Yeah, I just watched some youtube video about japan and their outlets, and how they have a full house gfci breaker basically at the panel, and it takes care of the same thing as us running a ground to every outlet. But they are transitioning to US style according to the video.

hey can you tell us what model or whatever you have? I just bought some tanked water heaters for an off grid, but I would like to see this hybrid heat pump model you have or bought?

So I included a picture of proposed future buildings that need to be powered by solar. I have 32 400 watt aptos bifacial panels to power the 3 buildings with solar. Each one will have a solar mini split, and lighting, I need enough battery to be able to basically power lighting, and a gaming...

Basically what this guy said. I actually live in a shipping container. But it is the stainless walls and is a reefer container. So it is pre-insulated. USA dollars, I just payed 6700 for them. 40ft x8ft. That said they do make smaller ones. You can get 8x20 and 8x10s I believe, in the...

Expired when I just tried it.

So, when people all mention JBD and ordering stuff from Alibaba direct from JBD, is this the store they are talking about? https://www.alibaba.com/product-detail/JBD-48V-300Ah-15KWh-LiFePO4-Lithium_1601262064040.html Quote I got is essentially $1499 per battery plus shipping for 280ah units...

I am trying to setup this eg4 where it replaces an mpp solar lv2424 that solar input died on. That inverter worked ok for a month and he could also use his generator and charge his 2 eg4 24v batteries through it. But since it died, he replaced it with an Eg4. Both his batteries are 24v. The...

Ufer ground calls or 20 feet of rebar mininum, sseems to me if i ufer ground a rebar footing between the 2 so the rebariis continuous between the 2 and welded to each foot, id have my g4ound and same potential.?

Hey guys, long time lurker... I have been looking and trying to figure it out, but, I haven't seen the answer, or I did, and didn't comprehend, or I am asking the search engines the wrong thing. Anyway, here goes my question, and what basic system this would be in reference to. If we got a 24v...

I didn't fully read, my bad. delete if I can. otherwise edit I guess.

Hey all, so I ordered 2x 300ah 48v batteries from Enikol / Damien New Energy Technology (shenzhen) Co., Ltd. on Alibaba. POC was Iris Huang, and out the door was $3200 US Dollars., I ordered back in November. (Who knows what the new tarriff in town will make it) Each battery was $1010 with...

Ok, you guys can keep telling me how it works. Theory crafting is fine, but i'm living it and giving real world evidence of my situation, and I don't know why people want to argue with me over this. Yes, the mini split removes moisture. I have 9k btu, undersized, still humidity climbs up to 70...

Yes, right after I posted I saw that as well. I did search by companies that have shipped to the usa verified. I believe you are right and they are different companies. Their batteries look legit, and are priced higher than a different manufacturer that was quoating me around $990 per 280ah...

Does smacking it help the sound go away? Like does it seem like a fan with a bad bearing? Would they make this noise if it had a leak, and leaked enough coolant?

I wasn't aware of the 16kw watts having a manual for it, What is the price when you contacted about the megarevo 16?

I live near a wash in Arizona. it's sandy, rocky, and it has caliche. You can't dig three inches without hitting another rock. Some baseball up to basketball size. Some are, most of them are the smaller softball size.

Nice. Do your Mini Splits already have soft starts, or is that just planned? I have 2 of the eg4 9k non hybrid units, and 1 of the 12k solar hybrid units, but I changed my panel mounting before I got started. I have 39 panels. I was going to do 18 x 2 on top of the two shipping containers, but...

Got ya. I think I'm still doing 3x10 and 1x 9 since and a spot for 1 more panel

Nice. I am doing fixed angle at 45 degrees. I am also doing angle iron 1.5x1.5x 1/8 thick welded frame. Your setup is nice. MPPT Voltage Range (with battery) 120 - 430V (thats what my spec sheet says for the nhx) So that's why i was planning just doing rows of 10. When I did my calcs I did...

https://watts247.com/product/its-here-nhx-12kw-with-built-in-breakers-for-battery-and-ac-teminals-18kw-pv-12kw-120v-240v-output/ I was pretty much settling on the NHX 10kw from watts 247 then I saw this 12kw just launched, and almost bought it, but slept on it. Looks like the 18k clone...

So, this isn't my system. And I think you guys helped me in the past, but I think I may have the issue kind of figured out. TLDR: neighbero changed inverter from mpp solar lv2424 with 80 amp 150v mppt to eg4 with 18 amp 450v and didn't change panels fro 3s3p to 1s. Has 9x230 watt panels...

Well a lot of the company reviews appear to be very suspicious as fake. (at least one red flag there, just not sure how big or bad that really since nearly every company engages in it) Still looking into it.

I have went so far as opening the box, and opening the front panel and staring at it. I haven't attempted to even lift the unit out yet. I have 2 shipping containers 20ft apart in parallel and I still have to build a small solar shed to house the batteries and inverter in to act as the main...

Yeah, I was boggled his system worked at all. Yeah, when I started looking at his system, and as I learned more, and last night I was thinking about his system and had that epiphany. I tried to get him to change to 9 panel string a while back but he didn't want touch anything because the...

Yes, I am in the USA. I believe the grounding method is "ufer grounding" which says 20ft of half inch rebar within 2 inches of concrete like what would be done in a slab, or in this case my footings for the container, I wasn't aware of needing 20 ft for ufer ground before I made this post, but...

I never did crack it open yet. I move real slow. It is good to hear that your stuff is going well for a few months now.

EG 4 does make a pretty affordable standalone charge controller. https://eg4electronics.com/categories/charge-controllers-mppt/mppt100-48hv-eg4-solar-charge-controller/

Thanks for the feedback, I will try to complete the audit, but I believe the sample provided in the sheet would approximate his normal loads, and trying to basically get it as KISS as possible and plug and play as possible, and I did inform him, we need batteries. So still figuring out.

Sorry, posted accidentally.

Ahh, I forgot, I mean it seems quality. I haven't taken it apart to stare at it more, or take pictures. I guess I could do that here shortly, wouldn't be to much trouble take the cover off and look at it. I don't touch no internals, and definitely am not an expert on internal electric parts.

Not particularly. I'd think anyone that gets normal ones could get the insulated. They just cost more.

I remember reading that thread, but also don't recall what the fix was, I do think it was the neutral ground screw in the inverter, but I can't say for certain without digging it up.

Good to know. However, I think running this dehumidifier at 125 watts probably consumes less power than running a smaller a/c longer to take longer to cool so it can dry the air more. I haven't tested it, that's just what my brain tells me.

Wouldn't it not cost very much to just get a Positive and negative bus bar? https://signaturesolar.com/600a-12-stud-busbars-red-black-kit/ Then you connect all your batteries to that. I haven't done this, I don't have batteries, or my system up yet. But it is what I have seen being recommended...

Mine is still not connected or hooked up. So I can't help ya there.

I live in Arizona, and we get random huge wind spikes, but the dust devils (mini tornados) can spring up anywhere, and they have been known to throw trampolines, flip boats, rip up carports, and all sorts of mischief. So Since I got solid rocks every 3 inches in my calichie, I plan to wood fram...

So we got this resolved. He did end up running fuses anyways in line with the negative and positive before going to the solar disconect, then from disconnect to the inverter. Inverter had 90v bug, had to update firmware. That all went smoothly. And he finally pulling 1.4kw incoming to charge...

So, I have 2 insulated steel reefer containers, will be AC inside, and DC outside in the battery inverter cabinet and the batteries and inverter be anchored to the exterior of container 1, and container 2 will have AC panel inside and DC roof solar to run over to container 1. The containers are...

where do you get those and how much are they?
