Did you measure each individual cell and put the values in? Measure during charge or idle? I'd have 160 cells to do

I have like 5 multimeters with 1 being a fluke. So I can always go by what they say.

Ya I think if you hit the LiFe Po4 button it is a reset. I've done it several times when I was trying to set the parameters. Lol Later I realized if you hit the button it resets it and that's the reason why my settings wouldn't take I guess I can try and catch it again doing that. A lot of...

Yes I have it at .005.

Nope I hadn't changed anything but the balancing down to 3.4volts. When they were hooked up to the overkill BMS it also would say 3.7volt on some cells. Even though the cut off was 3.65. I've always wondered if something was wrong with the cells. This isn't the only bank that would show weird...

This is the settings on it except I did change the start balance to 3.4 instead of 3.45. Thought maybe a little sooner would help.

Ever seen Voltage go this high on a cell?

You should buy those grade B envision 305AH from 18650. I have 4 banks of them with a JK bms and have been flawless so far

Ya it is. I didn't want my brother going and getting a solar installer but he wanted a professional putting it up. Well dude has apparently ripped him off and many others. State police, sherriffs department, FBI etc won't touch it. Even contacted the state attorneys office. This guy has done...

That would be a very interesting graph to see. I know when solar installers come around they try and sell ya on a 8kw system and make ya think it's all your ever gonna want or need. When actually it needs to be at min 2x that size for a smaller house. When the government mandates everyone has...

Ya I bought some 250 watt panels from santan solar. Have 104 of em I think it was. Was going to put them on my shop with some facing east and some pointing west. My dad died unexpectedly before I got them up. And I took on the building of his solar for his place which my mom and younger brother...

My electric bill for December was over $300

I have 4 strings at 436 volts I think it was. And another string at 288v

I guess that's the magical question. No one really knows how much time without production will occur. Besides night there are days or even weeks of not much sun. Think it was the month of December I had 2 days of sun. Around like 4 or 5 with partial sun/hazy skies and the rest was just cloudy...

Well usage varies. Depends on if clothes are being washed, dishes washed, could be watering the garden (have a well) also have a greenhouse that uses fans, have I think 5 deep freezers and 3 fridges. Also have a seed starter room that is kept warm with grow lights for seedlings. Have 2 shops...

Your panels do a lot better job of producing current in the rain. Lol mine produce nothing close to 30% production in rain. It may be closer to 5% 😆

Before I bought more cells that is precisely what it was doing in certain times of the year. Mainly late fall through early spring

48

Right now I have a 19kw array. Have 3205AH of LiFePO4 and was wondering what size array do you guys think is adaquate for your batteries? It takes a full day of sun to charge mine up to about 60%. By late in the afternoon of the second day it will be around 100% depending on how much current I...

Ya it was balancing at 2 amps. I thought about getting a 48 volt charging and putting it at 57 or 58 volts and let it charge just that one string of batteries.

I dunno if it's just something wrong with the BMS saying 79%full and it's really 100%? I know that 5 of 6 of the 280AH packs were imbalanced a great deal when I was using the overkill BMSs. Only 1 of them was still 280AH the others were all over the place like 157AH 170AH 210AH etc. The over...

Don't know how much charging I'll get in the next week. Supposed to be cloudy and rainy for several days

It won't charge beyond 79%. Even If the other batteries are topped off at 100% it could take 19kw of power but will only take but a couple amps and not charge any more. At noon I cut off the discharge and lowered the balance to 3.40. It had a draw on the battery while the other banks were...

Can you just hook up 2 of those batteries in series for a 24volt battery?

And he didn't understand why either. I've watched that video before. What mine is doing is just not charging. Other batteries are at 99% full and still pumping in 30 and 40 amps each and this one sits on 79% and hasn't moved in a couple days now. Says charging but very little current going in...

I got all the cables the same length for equal charging. This particular string is around a year newer and has welded on posts compared to the screw in posts on the other 280s. This is now day 3 of it charging and balancing Full sun at noon. All other batteries are at 100%

Also I changed the settings on the low end . Didn't want my batteries going to 0. So i raised it up a little. My BMSs apparently have different software. What do you guys think of those settings

I saw the -20 Celsius setting lol. Here is something I didn't understand battery pack no where near full with the bms cutting amps off and other packs still charging with a lot of amps at 100%

Ok thanks for the input guys. When I get home I'm going to change the charging current on all 10 units

I replaced 6 of my overkill BMSs with JK 48v 150A 2Amp because of the out-of balance the cells were with the over kills. In all I have 10 of the JKs 4 of them on 304AH Envisions 6 on 280AH Eve On the 6 280AH I replaced the BMSs between Saturday and today. Of the 3 that I replaced Saturday...

Buddy of mine told me he was renting a place that had tanks but the guy he was renting from didn't own them. Had to buy propane from the company that owned the tanks. Said it cost close to $4 a gal!! I have never paid above 1.70 before. This year I could of paid 1.20 but I was already pretty...

I'm not sure what he means by outdoors or held up??? Is outdoors like in a shed with no heat? Or outside is having all your equipment batteries and all just sitting in the yard chilling?? My setup is not in my house but in a shop that's not heated or cooled. I built a room for them that is...

In the future I'm sure the government is going to ban anything that is not electric. And I'm sure electric grids will be unstable and collapse during peak hours like they do in 3rd world countries

I have 3 shops I'm also supplying power too. And you also have water to heat, cooking, clothes washing etc etc etc. When in the winter it's cloudy and produce no more than 10 kw in a day if your lucky your going to run out easily. I had snow and ice on em that would not clean off. Had to wait...

I have 19kw in solar panels, 148.8 KW in lithium for a 2000 sqft house. Heat with a osburn fireplace insert. Temps got down to 0 with windchill down to -15. Hasn't been above 32 in 10 days now. Never worried about cold temperatures in the house. It was hot! I had to open the door a few times...
