Just ordered 3 6000xp's and 2 pallets of panels, will be a fun spring. :)

Don't see why there would be a limit as long as they are 48v and have bms's for each battery. I have ~160 kwh's of batteries on my 3 6000 xp's in parallel.

Just had my inspection, he was very impressed with the system and felt everything was good to go but wanted to review the codes before giving a green sticker, so he said to schedule that for next week. The only thing as of now he pointed out was I need to label the conduit outside that it is a...

The inspector never mentioned the decommission plan during final. After he mentioned it to me when inspecting the trenches the first time he was here I later that day did some searches and could not find anything other than 50 mega watt installs had to have one, I texted him asking if he could...

I have 7 Sennville Aura mini splits in the house, pole barn and solar shed, used for heating and cooling, Extremely efficient for cooling, not as much for heating but I suspect still cheaper than propane.

For those that do not know you can also build a 306 ah battery with brand new mb30 cells and a diy server rack case with jk bms and screen for about 1700 shipped, I just ordered and received 2 more of these a few weeks ago. I have 4 of the Yixiang diy cases and mb30 cells and 2 of the gobel...

9am and getting 9000 watts, very exciting :) The array pointed 15 degrees towards the east from south is producing double the wattage of the other arrays.

9 am and the array that is pointed ~15 degrees towards the east off of straight south is getting double the output of the other arrays.

I ended having to have to have engineered/stamped plans for my ground mounts, I found a local engineer and told him exactly what I wanted, charged be 1000 bucks for stamped plans and were ready a few days later I built 3 of them (and doing 2 more this summer). Passed all inspections and had the...

I found 2 things that are causing flicker, one of my 3d printers, its ac heat bed once it hits temperature and then maintains it, it cycles off and on constantly, that cycle off and on is causing the flicker in the shop. I have a 3d print farm and all my 3d printers (bambu lab printers) are all...

5/16 worked on all my 6000xps.

I am not taking the cells apart, I am just cutting the bar to remove 4 of the cels to leave a 16c pack.

Okay been playing around, it is flickering when on battery, was not when grid was kicked in. I was pretty sure it would do it all the time previously, maybe I was mistaken, I will have to do more tests to find out for sure.

JK BMS's have been working fine for me so far in 6 15kwh diy batteries (MB30 cells) and I have 5 more to put together yet.

I ran a ground wire from each array (grounded to the frame/mount of the panels) into a grounding bar I put in my solar shed, the grounding bar was grounded from a nearby breaker panel, which is grounded from my grid ac ground. I only have the 2 ground rods (6' apart) that were put in for my...

Hopefully he will not require it, the pole barn has 61 degree roof where the panels are mounted, don't think a fire fighter will be up on that roof :)

I was going to go with 2 schneider xw pro's but these look pretty attractive especially considering how much less expensive they are. I want reliability (will be for my home, pole barn and work shop) and needs to have enough oomph to handle large startup loads. These are looking pretty...

Anything stand out as you are going to fail inspection? All the grid side AC stuff has been inspected and approved already, all the solar stuff needs to be inspected yet, will schedule final for next week.

I have already decided to not sell back, I just want to have panels, some batteries (that I can expand as time goes on and I can afford) and tied to the utility when there is no sun and the batteries are dead, which will be all auto switched I am assuming with the ek4 18k (without power loss?)...

It was "only" $65 but wanted to see if this was a tactic they were using for others or just an honest mistake.

Off grid garage is how I learned of them, the gobel diy case and the new Eve MB30 cells, which is what I ordered, I used his links to order from his website, so hopefully he gets his commission, love his channel, so informative and I am a solar newb so have lots to learn. :)

As of right now I am leaning towards dual schneider XW Pro inverters.. but still trying to figure it all out. :)

Okay, I went out to check it and it is no longer in that same state, it was charging like normal. I will keep an eye on it.

Form completed, thanks.

It has to be approved with the power company or something, I dunno lol (this is not a grid tied system either btw, has grid as backup but not back feeding) and some department in the state, I don't remember which one he mentioned.. he said it is not legal to transport those batteries unless...

I top balanced all my packs with solar/6000XP inverters, just turned off discharge in the BMS and adjusted voltages as they charged, took a few days to get 4 306ah packs fully charged/balanced, now they are within 0.000 - 0.005v variation between cells within each pack as they discharge and...

The battery was down to 7% this morning before the sun started picking up some of the load. Before noon now and batteries over 50% :)

It will make 5 packs, each pack will be 14.3Kwh so I will need 5 BMS's total.

I have a clamp meter, next time I am at the new house I will see what the well pump pulls on start up. I don't have my shop built out yet but it will have multiple 220v circuits for things like air compressor, table saw etc. If need be I can get an inverter for each location, the house and...

I am new to all this and not sure where you would buy brand new grade A cels from. It seems like these were a good deal, be like 130-140 dollars per Kwh once fully built. It does not seem like too much work, I will just cut the battery bar to disconnect the 4 cels and leave them in the tray...

There was no science involved in it for me, I built 1 of the 3 ground mounts (adjustable angle) about 15-20 degrees towards the east from south and 1 the same towards west from the south just to pick up a bit more power earlier in the day and later in the day. The 30 panels that are roof...

nope :) Still no flickering yet since turning off the one inverter, will monitor throughout the night etc.

They are available again, I just bought 4 modules tonight.

Just checked, they are all set to 120/240v, thanks for the suggestion though.

I used 8 gauge and 40 amp breakers.

I assumed it was to the negative side but I like to have verification from others, your response was not helpful. I have completely rebuilt my pole barn, including all the electrical, insulation, epoxy floors, framing etc and many other diy renovations, builds and so on. I have been a diy...

Still waiting for a reply from sales/support to my email, hopefully they are able to get to it soon. Let's see who wins, just emailed current connected as well, signature solar had a 5 day head start though. Shipping is a bit cheaper with current connected for me too.

of course it is the array on the pole barn with 61 degree roof that I had to rent a telehandler for.. figures.

Well that is where my issue is, I don't get flickering at all ever when on grid (when no sun and batteries are dead so the inverter switches to grid power).

I just took a quick video with a run through of the system if interested.

No you are right, I am using the shelf you linked, 4 of those shelves, the ones without the perforation in them though, just solid top but same weight capacity, like 330lbs per shelf.

The 6000xp's are cheap and have great reviews overall , if they fail it is easy and cheap to swap one out and can easily add more if I need to expand the system.

Cables glands, that is what I was looking for, thanks!

I don't think its sketchy paying via CC or Paypal but after getting a quote for the product and the shipping quote to my address and paying the invoice they almost immediately email me back saying I owe more money now for "remoteness" delivery fee, (even though when I was quoted I was told due...

Yeah the XW Pro's need like 8' of space at least lol (I will have a dedicated solar shed, so no big deal either way). I emailed signature solar asking them a few questions about these, so waiting to hear back to decide.

Okay, so the panels themselves don't plug into the inverter, they would go into the charge controller.. looks like 600v.

All different ones, through the entire house/pole barn, mostly led but even a fluorescent light fixture does it.

I will not be selling back and nothing inspected unless I legally need to have that done. I will not have anything roof mounted. I am looking to run off solar when its available, batteries when no sun and fail over to grid when the batteries die and having the ability to charge the batteries...

I bought 5 "new" jk bms's over a year ago, right after they first came out (and have bought 6 more since) and all of them are hw version 15, I think version 14 may have been a first run of them perhaps?

I ended up just ordering a 4th 6000xp to parallel with the other 3 and can add 20 more panels total to my system. The other 3 6000xps are already maxed out with panels.

I agree, it works for me as well, on compete overcast days it obviously is not all that great but still get 1000-2000 watts consistently throughout the day. Had sun shining the other day for part of the day and was producing over 24k watts for a bit. It was sunny this morning and saw only like...

It is on a pole barn, the conduit box will be attached to the roof, it is a roof top junction box for shingle roofs.

put a camera on it so you can replay the video and pause to get the error code?

Yeah, I agree I don't think it would make a difference but ultimately my goal was to not allow the new 12000xp inverter ever get power from the grid.. but that would not end up working anyway if I were sharing the battery bank, because the 6000xp's would just be supplying the grid to the...

I am going to be setting up solar in my new home. I plan to run off solar/batteries and will still be connected to the grid in case no sun and batteries are dead. I also have a whole house generator that can be incorporated into this as well. These batteries are the first thing I have bought...

my 3 are nearly identical. Latest firmware?

If you wanted, see if you can change it to the new JK BMS, it has a built in 2a active balancer, it's one of the better bms's on the market (according to off grid garage and he is a pretty smart dude :).

Which are recommended panels to go with? I will be starting off with about 14kw of panels. I see KB solar has them that are made in the US, anyone have experience with those, the price seems good. They will be ground mounted if that makes a lot of difference. Thanks all

I did. :)

Can build one for pretty cheap, two 306 ah batteries and server rack case with jk bms for 1700 each.

I know that but it would only be used as earth/ground, they use bare copper and direct bury it when used as ground. Does anyone know for sure if it would fail an inspection?

I went through all my panels and sub panels on the property and found 5 circuits that had the ground on the neutral bar (was in a sub panel in the house), so I moved them to the ground bar, not sure if that would cause these issues or not (it did not up until this point if it could cause...

Is there a way to diy a system that can still use the utility company power but does not sell back to the grid but instead during the day charges a few batteries with the excess power from the panels and when the sun goes down your system uses the batteries but if the batteries were to die you...

It has nothing to do with the money, just never occurred to me to put it in conduit since I had direct bury wire. I have put 50k cash into this project, a couple hundred bucks makes no difference but like I said it never occurred to me. If I have an issue later then I will take an hour to dig...

Spoke to signature solar on the phone and they told me no reason to get the bluesun over hyperions.. and went even further and suggested the Talesun 400w bifacials over either of those two at only 3600 a pallet (36 panels). So that is what I did, bought 2 pallets of the Talesun. total cost for...

Hey there, 5 packs are 280ah cells and 4 packs are 306 ah cells.

Thank you for the info. Looks like a decent deal with these modules I bought after checking the stores you mentioned, they are ~135 each for new individual 280ah cels (not sure if shipping is extra, which would make them cost a bit more), I paid 9150 shipped for the 80 that are in packs and are...

Yeah, all the panels at 60 degree angle are now cleared like you said, must have warmed up some, I have 10 that are at a 22 degree angle on a roof, they are still covered though. I ordered a brush with a 30' handle. Was hitting 15k out of 24k (30k with bifacial) total an hour or so ago, was at...

signature solar

It seems to be when on battery power it flickers and not when the grid has kicked in. All 3 inverters are back on and so far only seems to be happening when on battery.

Yeah I will only run like 2 of them during the winter, will use one to heat my house and the other to heat the pole barn lol, turn off the mini splits then. Have to figure out a way to do that, these put off tons of heat and are really loud. It is best that they run 24/7 without startup...

Yeah, hope so too, they have been around at least 10 years.. as I was able to find youtube videos that are 10 years old talking about them. :)

Yep, I am in the research phase now and I knew I wanted to diy the batteries, can get double or more the storage for the same cost as off the shelf batteries. I am a diy type person so I don't mind a challenge and I am not taking this pack apart, only cutting the battery bar to remove 4 of the...

I will double check it, like I said though I had no issues for the first ~2 months, this issue just started but I will check to be sure all the connections are good.

My stamped engineered plans show 10 gauge grounds to each array.

Okay, this is exciting, everything is powered on and is working! :) I have a question though, I have 3 6000xps in parallel, I watched the video on setting up the jk bms to communicate with the inverter and works perfectly but what about the other 2 inverters, I have the battery set as lead acid...

I plan to put all the solar equipment in a shed, there will be ~75' to get to the house and about the same for the shop. I have not decided on this yet for sure though. The other option will be put the shed near the shop and then a 100+ foot run to the house. Maybe it is best to just start...

Anyone use KB Solar Panels? Are they any good? I am just starting my diy solar install and looking at panel options. I see they are made in the usa (parts sourced from china I presume) and they price seems okay at 225 for 450 watt panels. What are the most recommended panels to use, I plan...

Business sales tax license, setup will be used for shop/business

Yeah it is a lot but ultimately I don't want to rely on grid power at all. It is for my shop (business) and my home, I average about 4-5000 watts usage around the clock, sometimes 3k being used and other times 9-10k being used and live where we get snow so wanted enough panels to generate the...

Hey there, I already have a Siemens FS140 whole house surge protector on each panel in the house/pole barn, 3 total. Ohh and another one on my disconnect outside the house, they put one in when the electrician had to update to latest code when putting in all new panels in the house, so 4 total...

I was watching some videos on the XW Pro last night and am considering two of those, enough people have said to choose something other than the EG4 18k so it may be best to look elsewhere, it just seemed easy to use and an all in one package. I am still learning about all this stuff obviously...

yes

It is the JK-PB2A16S20P, has the dip switches etc.. I currently have 4 of them all communicating with each other in parallel.

Amazon just delivered it, nice having same day delivery.. and I live out in the sticks. :)

Yeah they are inexpensive and the Talesun are even less, at 100 bucks a panel (95 with 5% discount they gave) it seemed like a good deal to me! :) How are the hyperion performing so far?

Okay nice, I will order one of those shunts then and I have a few rpi 4's lying around I can use. I will worry about how to setup/install/configure Solar Assistant once I get the green sticker and figure out how to setup my inverters and bms's etc. :)

The photos above are not mine, my batteries will be here thursday I think. I am pretty sure I am going with 2 schneider XW Pro inverters. From reading they seem super well built and can handle large startup loads. A bit pricey but I want reliable power once the system is all setup and going...

Okay, good to know. I will see what the inspector says on Monday assuming he calls me back. I did not know I would need separate permits for the inverters and batteries too. So that would be 5 permits total for me then if so. I have an electrician doing all the AC stuff (moving service...

Can I use these panels with two of the Schneiders? See any reason not to go with these panels? Price seems good? 225 per 450 watt panel and $1 shipping for 32 of them. Besides wiring what other hardware would I need and is there a specific bms I should use with diy batteries for the...

I have the inverter talking with the bms. I currently have 4 batteries with jk bms in each one, they are all parallel to each other, the bms's. I have the master bms connected to the master 6000xp and they are communicating just fine, what about the other 2 inverters, they are still set for...

I can't pin point where the flickering is originating from, it definitely is only happening when powering off the batteries though, like right now, the flicker is driving me nuts in my shop, (again, it is not just these lights, does it with most led lights in the house and pole barn and I have...

Doing a solar install, my understanding is everything needs labeling and plan order labels via pvlabels, so the conduit needs labeling as well or just the boxes/disconnects etc?

Yeah, over time I would add more batteries and panels as needed to help with winter months.

Well I turned the disconnect off on the problem string and the disconnect for the other array into that 6000xp and swapped them in the inverter from pv1 to pv2, turn both array disconnects back on and now both arrays are producing normal power and voltage, so very strange! I will keep an eye on...

This is because the UPS can't handle that much load, UPS's are rated for max current draw, most of the models I have (APC and Cyberlink's) have around 900 watt max load rating. The circuit only has lights on it also, so I don't have to worry about anything else running off it, not sure it will...

Yeah when I got into it 7 years ago I had wished I had gotten into it a few years prior lol. I just mined and held also, I only mined for about 6-8 months, I bought like 60-70 video cards at the time, spend like 30k on them, mined with them (all different alt coins and ethereum) and then...

So how about the other settings, do I need to set all the settings in each inverter or will the slave inverters automatically adopt the settings of the master inverter regardless of which settings you put into each of the slave inverters?

Thanks all for the information, so when connecting them to each other will the + of one will connect directly to the - of the next panel with the leads that are on the panels already and I will only need leads from the - on one end of the string and a lead from the + on the other end of the...
