Docan power seems to have revamped their website. Additionally, they have stateside LF280K gen 3 cells for $68/ea, MB30 for $73/ea, and MB31 for $77/ea They have 280ah CATL listed for $60/ea and 320s for $62! REPT 280s for $50! Lastly, they are now offering their apexium boxes as prebuilt...

I don’t know if there is any value to these or not. They were delivered as you see, unfortunately. I have no plans for them, if noone wants them, that’s okay too. But if they are of any use to someone, let me know and they’re yours They are all in similar condition

Okay, back in October I found some murmuring about this site. I went on and found some good deals but noone with reviews. I bought 2 pallets of HT solar 370w panels and they arrived without issue. After a successful test run I then purchased 4 pallets of NE solar 370w panels and all remaining...

Saw a listing and thought it was a respectable deal Buddy of mine has been looking for panels and slept on the NE deals from Inxeption I sent him this link and he purchased a pallet. Sounds like the place has a bunch. $2000 for a pallet of 31 panels isn’t too bad Note: I have ZERO...

Stumbled on these today in my rounds of searches. LF280K new version US warehouse $85/cell, shipped. Tax free. https://batteryfinds.com/product/us-stock-eve-lf280k-new-version-280ah-lifepo4-prismatic-cells-4pcs/ Battero (REPT) 280. $89/cell shipped. US warehouse...

I’ve been banboozled by trickery please delete

Has anyone used these battery breakers? When I search DIHOOL by title only one thread exists. Seems they make plenty of PV options but this looks like a pretty hefty breaker I had nearly ordered a couple of Naders, but these seemed intriguing...

Looks to be a cool idea. Going to be an expensive kit for sure but in the video they do elude to a version that could adapt to existing engines and just replace the axles and add the batteries and generator. Would be neat on a 12v Cummins ram!

Was scrolling a Nissan leaf group and a guy posted minimal pics of a diy Lifepo4 conversion he did. Claims its 180ah catl cells with ~60kwh capacity. Hasn’t provided any other details but says he’s $5500 into it, and you can find gen 1 versions for about that price or cheaper too. Would be neat...

48/10000 120v Quattros at AltE for $2,336. That’s 1300 off retail. (Free pick up in MA, no success yet in finding a valid coupon code) 20kw split phase Victron wall would really upset the anti blue crowd. Who’s gonna be the new eurotrash fanboi group leader? I want it to be me, but I should...

Does anyone know of any ~7.68kwh prebuilt batteries outside of cloudenergy Even better would be bare cases designed for 150-160ah cells If the latter, I’ll need to dig dimensions as it doesn’t seem cells are as universally sized as the larger ones. The cloud energy batteries offer an...

So I’ve been on the hunt for a chargeverter or 2 for a little while now. I saw a post that Dexter mentioned he was expecting a shipment soon as as per my MO, I began hounding him and Jason with questions. I wanted to buy a handful of items and they were gracious enough to provide feedback on...

Shame it’s not closer to me. Figured I’d pass the link along. No affiliation. Just stumbled upon it when searching classifieds. https://sfbay.craigslist.org/sby/for/d/san-jose-solar-batteries/7713201788.html

Don’t know anything about either company but their advertisement for the 5kwh rack battery is identical to jakiper/orient power. It’s listed for $885 and free shipping They have a 230ah rack battery for $1679 and a 280ah variant for $2000 All free shipping...

List price of $55/cell. Put 34 cells in my cart to see what freight would cost. Turns out, they have another discount of 15% off >$1000 orders. OTD price for 34-280ah cells to my door is $2156.60 (600 in shipping and fees hurts)...

Yesterday I was driving home from an afternoon trip with the family, exploring some natural wonders I noticed on my drive, along the interstate is one of the BNSF railways About every 2 miles was a mountain of used railroad ties Anyone got any thoughts or ideas as to whom one would reach...

Seems these have been gaining popularity. I had considered building one into a pelican case and then I stumbled upon this one on YouTube last night. Snagged one for the homestead, camper, shop, or just to have as backup heat With coupon was only 209 delivered. 8kw heat output, 6L diesel...

Just got an email showing a promotion for the EEL box with JK BMS Not a bad price at all for $539 If I have 2 boxes already with the old BMS (which I believe is simply a seplos) would one have advantage to add 2 of the same, or would adding 2 with the JK BMS work fine? Is there benefit to...

This thing looks rad. For auction now on batteryhookup. Unfortunate state of the cells and lacking details but just thought others might appreciate the ingenuity. https://batteryhookup.com/products/pickup-truck-battery-enclosure-with-120x-3-2v-60ah-discharged-2

Greetings, I was hoping some of you might have some insight, scrutiny, and/or suggestions to my diagram. This is my first attempt Inverter: Sungold/SRNE 10kw Manual calls for 2p-25a 10AWG PV in, 3p-63a 6AWG AC out, and 250a 1AWG for battery Panels: 8s 370w x2 (one string into each MPPT)...

So I was reading about solar assistant, which then led me to reading about raspberry pi, which made me wonder if a micro pc would work instead as there are now quite competent AMD and intel versions So I decided to go to their website and I found out it’s pi exclusive. Okay, curiosity solved...

Silver frame half cut 120 cell panels 31 panels per pallet-11,470w per pallet New in box, never used or mounted. VOC: 41.0v VMP: 33.92v Dimensions: 69.1”x40.1” 44lbs each. Full pallet: $3300 (less than 30 cents per watt!) Per panel: $125/ea (less than 35 cents per watt!) Pallet weighs...

So I’ve tried to find a thread, blog, or article with a mathematical comparison but have some up short. Let’s say someone wants to run a string facing due east and a string facing due west. Rationale “extend hours of production off battery” For the south array it was fairly easy to determine...

Been getting a lot of emails from vendors with holiday/end of year type sales. And I also for no reason obsessively look at web page deals. Wasn’t sure if I wanted to post it here, or in the battery sub threads. In any case, it seems as though battery banks are often the hiccup for many. The...

Is anyone aware of a functionally similar piece of equipment to the eg4 chargeverter?

Well, let me preface this with advance notice of the following: I can be wordy, sometimes I may post a novel of a comment I can be reactionary, sometimes I don’t exhibit the greatest self control so if I reply to someone rudely, I’m probably already dwelling on it This thread will be in waves...

Functionally, supposed to be identical to the 10kw SRNE ASF inverter. I just wanted blue. I placed the order on Friday, Sept 29 and it was delivered today, Oct 4th. Free shipping. No taxes. $1745 to my door in 5 days In the coming weeks I will document in a separate thread (going to make a...

So I’ve been PMing with @Hedges a bit about SMA systems. Very grateful for the contributions and I think I’d like to expand to others for more insight as well. SMA Sunny Island does not seem designed to handle Lifepo4 banks. To mitigate, it appears that many utilize the REC BMS for lithium...

Scrolling signature solars website I noticed they no longer offer the 6000ex as a retail item, only refurbished They recently came out with the load center PDP for the 6500ex which implies they are still investing in its future Just read another post of a member recently buying the megarevo...

If one wanted a split phase Victron set up could they run a 10kva 120 Quattro with the Victron 100a autotransformer temporarily and later stack a second 10kva Quattro? And then maintain the autotransformer in the event one inverter goes down? Separately, if the second inverter and/or...

Another random thread by me caused by late night analysis paralysis hah. So I’ve been scrutinizing various charge controllers to delineate differences between various companies and help isolate future project decisions It would appear that of the “standalone” controllers the Tier One...

Trying to get my initial battery set up going. I’ll add more later either way. Ultimate goal is at least a 60kwh bank Current goal: as much battery as possible for $5k USD or less. 2 current options prevailing: 33 (one spare) Envision 304ah cells for $89/ea and 2-EEL V3 304ah box kits with...
