This will be an ongoing thread on my work in process expansion going from an SRNE ASF to parallel ASPs for additional power, 10KW wasn't cutting it... 4-24 edit - 10MWh 3-30 edit - 9MWh 3-9 edit - 8 MWh 2-14 edit - 7MWh 1-16 edit - 6 MWh 12-1 edit - 5MWh 7-22 edit - Current settings. Quick...

Was going to put this in the danger zone... It's a pretty eye opening video that should make one wonder how bad we really have it in developed nations... Getting by with what you have and getting it done works. They even used a Schneider breaker 😉

I don't even know where to start. Props to him for going solar and not using battery communications ?

Edit to add FS link. Send me a PM if you're interested. Pricing will be better for forum members. https://williamsport.craigslist.org/ele/d/danville-lg-neon-305w-solar-panels/7698501021.html End edit. For anyone selling on Craigslist don't fall for scams...

Watch out, I've been thinking.... With multiple packs in parallel is using closed loop really worth it? How many users are running closed loop with SOC that is not accurate across multiple BMS? I've ran open loop since day 1. I attached what my packs looked like this morning, big...

Sort of a ramble of random thoughts waiting for everyone to arrive for a bachelor party weekend (not mine, yet) while enjoying delicious hazy IPAs from a local brewery. How long till it really all made sense and you could sit back and enjoy it with nothing to worry about? (this should be a...

Posting this here because it will probably end badly. 🤣 @OffGridForGood had another one of his great ideas that could get people to spend money 😉. with happy sun and angry clouds incorporated. Add a broken piggy bank. Don't be a squid, stay off the grid. -something involving photons and...

Wild video and story about a fuse failing for a high tension line. Doesn't really fit it any forum here but I'm sure many will appreciate it. Lots of respect for all the lineman and operators out there.

Great video of panel manufacturing at KB Solar. It's reassuring to see manufacturing in the states and within a days drive... 2 minute mark if you don't want the intro.

I'll delete if I decide to make the drive ? https://newjersey.craigslist.org/mat/d/newton-solar-panels-rails/7623356870.html

Based of the informative info recently posted by @ChrisFullPower in another thread I'm intrigued in DIY'ing a charger from used rectifiers. A quick search on eBay for '48v rectifier' has made me realize it's definitely doable at costs much lower than off the shelf options... I'll start with a...

Need a combiner box for my 30p1s strings. I can't find a breaker either... ?

The majority of this was way over my head but it's very informative and the explosions are fun.

Excellent PPE 🤣

Interesting video in general. The solar and battery segment that starts around 16:30 could be a great topic of discussion. (easily watchable at 1.25x)

I haven't been a member very long so I apologize if this has already been covered. I see lots of the same basic questions posted over and over and over and over... Especially in the past couple months. Maybe we need a search DIY sticky... Something I made many years ago on my last addicted...

Seems like a great idea and layout. The components are to expensive for my blood but I could easily see myself building something similar with different AIOs and raw cells.

It's to awesome to not reshare.

Warning - music is terrible.

Haven't went down any rabbit holes in a while... Anyone else paying attention to the recent reports of the missing nuke the drones are trying to find?

If anyone is near Philly and capable of replacing BMS's this is a pretty great price. https://batteryhookup.com/collections/pallet-deals/products/2x-51-2v-100ah-5-12kwh-lifepo4-rack-mount-needs-bms

Great deal. I'd bet the price goes up once a bunch of orders come in. AmazonCommercial 600A AC/DC Clamp Meter, True RMS, NCV, Flashlight, 6000 Count https://a.co/d/jfVUz1D I paid $45 back in April. It's a solid meter.

Starting a new thread so I don't keep derailing others... @Eddie_Lux @SignatureSolarJames I have ali reseller telling me there is an exclusive agent in the USA for the Lux split phase, can you confirm or deny this? I have another reseller quoting prices well below anywhere in the US... I'm...

Great deal for anyone that wants to diy a 3KW power station, just add a 24V battery/batteries and some panels.... https://a.co/d/f5XXSmA For that price I'm really temped to have a another backup to a backup. Only downfall is the low max VOC. Post in thread 'Great deals on Power Stations.'...

If all goes well I'll have 48 more 230Ah cells by Sunday afternoon... Thinking ahead to how I should best reconfigure and incorporate them into my system. Here's what I have currently, each pack has it's own JBD, class T and Midnite 100A breaker. Here's what I'm thinking. Pack 1 - 305Ah...

Seems like a great deal. Shipping on ali is over $100. They have others as well, up to 120v DC https://batteryhookup.com/products/maisheng-mp6020d-professional-0-60v-0-20a-adjustable-power-supply

I'm ready to order the SGP inverter linked below, except for one holdup... Hold do you interpret this wording from the manual?

I have 5.67kw of panels, 2.835kw S the other W... I'm impressed / questioning if it's possible. It's been raining on and off all day, cool panels blasted by afternoon sun. ?

Idiots everywhere.

Gets interesting around 35 seconds in.

TLDR - alt e doesn't store cc info and you have to call for a refund if something is out of stock. A few weeks back I stumbled across NEC compliance stickers on Alte with free shipping and figured why not, ordered a bunch. (I don't ever plan to be inspected but try to do things the proper way...

Get ready, be prepared, be safe and enjoying living in a likely historic storm.

My Dad and Brother gave me an Elegoo Neptune 3 Pro for my birthday. Any great tips for printing solar components and anything else I'm missing out on? I've printed a few logos using PLA filament. I also have a roll of clear PETG to play with, I think this would be good for cell covers...

Post up where you ordered / are ordering your comforting goods. If the thread expands to much I'll try to index it / rank vendors based on how many mentions they get. I'll start. Jack's Small Engines on Amazon. Delivered in under 1 week. Great communication, thanks to FedEx I got the...

Not a bad video, watchable at 1.75x.

Anyone spot anything dangerously wrong so far? One thing I'm unsure of, should I bring the ground from the PV combiner box back to the AC main panel (new panel) or pound a new rod for the PV? I've done a lot of work with AC but nothing if this scope with DC. Thanks for all the great info...

Lots of chatter of AI on the forum, rightfully so, so how do we know who's X's and Y's and who's 1's and 0's? What if a new user had to post a photo with their hand written username next to their keyboard or hand or solar system, etc? Would that work to verify or is image generation that good...

Thought it was a poor connection, not the case, same temps after a new wire. Noticed it yesterday.

Don't hesitate to order from Wirenco. Recently (5-26) I ordered multiple cuts of various size and a bunch of stuff I didn't really need. In 3 business days (5-29) I was contacted by email that one of the items was out of stock and a refund offered. On 5-30 everything except the OOS item was...

Your comment about in the woods caught my attention... How far into the woods are you and what is your southern exposure like? I walked 12 acres after work today. The location is pretty awesome but I feel like I'd have to clear cut a massive section to get the exposure I'd need for anything...

Yesterday the grid was down for around 7 hours, only the 3rd time this month... Batteries were down to ~51V. (snow and no sun) I hooked the generator (5.5kw Generac gas) up to the TP6048 (LVX6048) utility input and was able to start charging the batteries after adjusting the time settings for...

Random thread... We're all trying to make more power... I recently added a redneck ground mount and a Victron 100/20 to help figure out direction for my next one. I've noticed the Victron makes, a negligible amount of, power longer than the SRNE many of you see me recommending. It also starts...

I could see lots of great applications where the weight savings outweigh the efficiency loss. https://news.yahoo.com/scientists-develop-mega-thin-solar-111500487.html

Realized the rings on the BMS terminals are to big for my cells. I'm trying to bring another pack online and charged up before 3 days of rain and shitty weather. Does this look OK? I know it was covered somewhere before but I can't find it. Thank you all.

Am I overthinking this or just being dumb? Currently have 2 9s strings connected in parallel via combiner box to my TP6048. Everything is working great except I'm not generating enough power. (it's sad watching generation going lower and lower each day, come on solstice ?). I want to add a...

Does anyone know of a database of manufacturers using LiFePo4 chemistry in their EVs? I really want to buy a used one for commuting to work, especially after adding the 3rd array and adding another ~15kwh of LiFePo4; the tax credit is the icing on the cake... I'll buy more batteries and maybe...

Has anyone done business with them? I'm ready to make an order, looking for last minute reasons not to. https://sunevo.m.en.alibaba.com/company_profile.html https://sunevo.m.en.alibaba.com/index.html

What would you pay for 48 CALB 230ah that have been sitting unused since 2022? What risks / issues are there purchasing cells that have been sitting? I think a road trip is in the works...

There were a few recent posts and a thread by a deleted member, VoltPolice, that were quickly deleted. I'm curious at to why, what rules were violated that made them vanish so quickly? Not even a new home in the chit chat zone?

KG160F shunt, has been working fine for about a week, I noticed the display was frozen. I unplugged display, unplugged power to the control module, no luck in fixing. The Bluetooth app still works fine. What I've noticed is the display takes an initial reading, that is accurate, when it's...

Skip to 16:53 and check out the Mercedes E600. Whole video is watchable at 1.5x. Some pretty brilliant ideas and new technology in the trucking world / our backbone.

Edit - solved. Shut off the other 2 breakers and isolated the problem child, started charging right away. Back to batteries and doing some laundry to drain them down for optimal photon harvesting tomorrow. I finished wiring up the 3rd pack and I can't get current to flow through the BMS...

I'm planning ahead for adding my 3rd pack and having trouble deciding on a proper disconnect. I attached a crude diagram of the planned setup and a photo of how things sit currently (expect the SRNE is in service) the packs will be reconfigured and put in some sort of enclosure / rack / cabinet...

Should be a good thread... If you had to pick 3 firearms to use for the rest of time what would they be? Type, brand / model, caliber. I hope this thread doesn't hurt my wallet to bad 😂. -title edit.

Excellent video.

I'm probably over thinking this... I currently have an oil fired water heater and excess solar. If I were to add a small 120V heater before my current heater could I get the small heater to circulate and heat the oil fired tank? It wouldn't work if I just plumbed the new hot out to the old...

I had another one of my bright ideas... I'm considering using 3 2x6's glued and screwed together with the grain alternating to make my posts for the mount. Why is this a bad idea?

It's my first time using a hydraulic crimper, I have a feeling I'm doing something wrong (besides leaving to much wire exposed)... Temco recommends 8 pumps as a starting point for 1AWG, I'm going 18-20 because 8 doesn't even leave a dent. I keep questioning the orientation of the indent as...

Anyone running a Senergy inverter or know anything about them? Specs look promising. https://www.senergytec.com/product/energy-storage-solution/se-5-10khb-ul/ Discuss. Ps I was quoted $1650 plus shipping through alibaba (from a seller with a good tract record).

I see a lot of discussion on naming convention as well as confusion. I don't recall seeing a master thread so let's get one started. If this is popular enough I'll work on formatting everything better and throwing into a spreadsheet. Model - AC output kW - PV input kW - # of MPPTs - battery...

Prime example of why you should draw everything out, check as you go, and/or not be a dumbass. Long story short I spent hours diying my buss bars to realize I f'd up. Solutions I see: 1. Order flexible buss bars from Docan or Ali, is aluminum scrap still up ? 2. Re-arrange packs because...

Does anyone see issues with cutting a small section (few inches) of rail and throwing a mounting foot on it so I can fit a 9th panel without having to use a long section? I have plenty of ground lugs and can run a jumper between if needed. I'd do this again on the W roof so I can fit 9 panels as...

I didn't feel it at work, lots of equipment running. Others in non manufacturing areas felt it. Looking at SA data there is a drop on my ground mount about the same time it happened, dropped to ~250W Coincidence? Anyone else see or feel anything?

Hello everyone, I finally purchased my first panels, figured $75 was a good price for 315w Qcells. I noticed some scuffs and scrapes when unloading them. Would you be concerned?

I used this for about a year before upgrading to a 10kW unit, commissioned in Oct 2022. If I remember correctly there are ~3MWh of solar through it. It was connected to a 9S2P 5.67kW array and ~22kWh of LiFePO4. 0 firmware updates have been done, there was no need to. It connects to Solar...
