Ya I was going to go with the mnedc 250A at altE but they closed before I could order so in my searching I found the 2 pole carling breakers for cheap and snapped them up. I have found that for some reason that eludes me electric switches make a big jump in price at certain levels , Like the...

I'm making up 5 - 16 cell eve lf280k v3 batteries and will be putting the A6T fuses as close to the + side of each bank as I can and a JK-B2A20S20P BMS off the - side , then the + from the fuse and - from the BMS on each bank will be going to a 2 pole 200A breaker(for shutdown and isolation of...

Ok so they call those bullet breakers , I have seen those in my parts searching . I am using something similar but a little bigger for disconnects on my DIY battery builds , 2 pole F series Carling Technologies DC breakers rated at 50,000 AIC DC along with A6T fuses rated at 100,000 AIC DC .

Could someone translate this please.

I sent a message to alte on their facebook page April 22 and I just received a reply this morning. "Hi , I'm so sorry, but altE was abruptly shutdown. Fortunately, the company's assets have been acquired by a very capable renewable energy product and service company, GoGreenSolar. We expect the...

I have/had 8 (7 now , 1 went bad about 3 years ago) 4/2005 dated C&D Technologies UPS12-475FR rechargeable sealed lead acid battery's I bought new from a canceled job in the fall of 2005 that I use for backup for my pantry fridge and 3 chest freezers when the power goes out. They only get used a...

So lets see if I am understanding this correctly. In the video it shows the scc is using 14 awg wire for the PV imput and eg4 thinks that is OK(because they are selling them in that configuration) for the rated 22 amps PV imput limit of the scc. While I see the wire is rated at 105c I would...

Thanks I did not know that.

The 200k AIC at 300v in the specs for that fuse is AC not DC. https://www.eaton.com/us/en-us/skuPage.JJN-350.pdf In the spec sheet linked above it just shows 300 v (V what , why do they always have typos in the spec sheets???) but if you look farther down on the second page under (Electrical...

You got a linkor part number to the connectors you use??

Has anyone ever wondered why Surprise Valley Electric in far NE California and Trinity PUD in trinity county California can charge on average just about 1/3rd to 1/2 the cost for their electric service (Overall , connection charge + electric + delivery) compared to the rest of California. And...

“income-graduated” fixed charge. Oooh that sounds so much better than Gibsmedat

Looks like I missed a thread already started on the 16th about alte. https://diysolarforum.com/threads/alte-out-of-business.82455/#post-1073083

Tried to order some parts last week and their online ordering does not work , have been trying to contact them for a week by phone and email with no luck. Someone posted on the alte store facebook page they were told by another vender that alte store shut down / bankrupt. Anyone know anything...

Here is some help. Don't waste any money or time on the wind , unless its blowing 20mph most of the time you will get more power production out of a (1) 100w solar panel than those 2 400w wind machines combined + they are noisy and high maintenance compared to photovoltaic's

Heads up , good deal. Just ordered another JK B2A20S20P BMS for my system build from hankzor at ali 86.03 - 1.72 coins - 8.00 coupon usaff8 +5.25 my local sales tax =81.56 - 2.45 paid with amex through pp for 3% more. = 79.11 Free choice shipping , has taken about a week-10 days for delivery...

Thanks here is what the evlithium site says about the lf280k cells I am using ( impedance resistance:≤0.25mΩ ) I plan on placing fuses as close to each battery bank as I can and was looking at class t 300A 20ka AIC blue sea units + I want to put in high quality breakers as a disconnect for each...

I am interested in finding out the AIC requirements (or even better a simple formula to calculate the AIC requirements) for fusing my eve lf280k v3 16 cell battery banks(5) (both individually and all 5 combined ) I am building without taking the time to get a PHD in the subject of LFP...

Nevermind I see SpankyOatmeal already posted the link above.

I used to run the plating op in sparks NV for superstrut before american electric corp was sold off in pieces and they moved the superstrut mfg to nuevo laredo mexico in the early 90s . It was zink plated followed by a yellow hexavalent chrome dip then a clear hexavalent dip back then which I...

I ordered some eve lf280k v3 cells from the latest batch 18650batterystore received in stock Feb 2024 . Ordered Feb 18 , they shipped Feb 19 , received Feb 26 (NW AZ). I had to handle each cell 3 times to get them out of the road and under cover. I did not see any scratches , dings or dents ...

I have a few of the LiTime 12v 100A TM batteries I use in my boat in a 2s2p configuration for running a mini fridge , microwave , coffer maker, etc When I was checking their capacity before installing them the bms would shut down charging at 14v according to the bench power supply I was using...

I recently put in a large order with solar sovereign and after 17 days of getting the in stock " Item will ship soon " response's I canceled the order and received a prompt refund . I won't waste my time again.

VOLTS . Multiply your voc x 4 for 4 panels in series and add 20% to be on the safe side as the voc goes up when the temprature goes down. AMPS . Amps stay the same , Isc (13.93) 1 string in parallel = 1 x amps 2 strings 2 x amps , etc. Not sure how bifacial panels effect the numbers as I am...

Got it I saw the switch and misunderstood . I am using an IMO si32 PEL64R 4 Enclosed DC Disconnect Switch for 2 sets of 5s2p hyundai 300 watt panels (196.15 voc , 19.54 Isc total each set ) the IMO switch has Max. rated current of 32A@600VDC and is rated to be switched under load. it has 4...

You have 1 string of panels in series , your Isc ls 13.93A , your maximum series fuse rating is 25A , you have a disconnect switch from your panels to your scc so you have the disconnect covered. A breaker (or fuse) would serve no purpose. You would not need a breaker (or fuses) . There are a...

Its 1 gigawatt in 3 years from the video. it is just a pilot plant. your calc is off by a factor of 10 and 3 years. 1,000,000 kwh /70 kwh per car is about 142,000 cars per year, 2700 cars per week. 1,000,000 kwh /70 kwh per car is about 14285 cars / 3 years = 4761 cars per year / 52 weeks = 91...

1 gigawatt capacity in 3 years is not much , average about 80 cars a week worth at 80kwh battery size.

How much total output amp limit do you have from your batteries bms , could the surge be making the bms shut the batteries down. thus switching to grid ?

Nevermind I found what I was looking for.

The statement on their sign "2 - 5 times the energy from the same space" and not having any solid numbers to share does not instill confidence.

Amazing breakthrough , Investors needed
