All my banks have a 1A balancer, turn on every 3 months as long as needed, usually 3 days, when in 5 days, something is pretty wrong, i think But some folks have stated those envision are pretty time resistant. I think i will give it a go, again you get what you pay for?

So it is clever to buy then or stick with EVE?

to80% of state of charge, if you are using 100% then you will have no more then 4000 left. EVE also has several species of cells, their not only for automotive industrie.

I have been lurking on them, great price. But looking on some numbers: envision---> 70%SOC gives a 6000cyles. EVE B grade -->80%SOC gives a 8000 cycles. So cycle life is less, what about self life? If even doing 1 cycle a day it would still be 16 years for envision and 21 years for eve. how...

Long life? 46 to 56V You will not see the end of them nor your children. Now they will see 70%soh left. In the meantime, you expand. In 20 years from now, there will be a other type of battery or chemistry, your kids will not even want your "old/obsolete" lifepo4. Not even 500kwh 70%soh...

Also negotiate with the seller if they are 80% under advertisement--->free return. Dont buy waste.

Thanks for all your input, it is really appreciated, just like every one elses input..... Long way from being done the correct way. But with you guys....i will have a dream system...learn me as much as you can so i can hopefully help others..... Again sorry for my english, it is not my native...

https://www.omnicalculator.com/physics/dc-wire-size I used this one for all my wires. For 50V and 100A it spits out 26,7mm2 I am way not close to capacitor capacity. So i really hope you can explain this one to me, cous i dont think i understand it, sorry. I will do that! I just did all with...

Agree... Short of storage....need more cells... Short of harvest....need more pv Oke i have easy talking, i have room enough, for batts and pv(130m2 can be covered in pv, and more if must) so i can do it with "old" panels. Panels from 25 years ago! give an average if they are good of 120wp per...

Oke good point! But, the ever enoying but...we have some clouds in the morning...that array does nothing...really nothing Oke we have clouds in the afternoon....that other array does nothing..... But those two arrays(up til now!) can keep us going after! expansion. But there is a problem: The...

Andy...yes also a good one. i did not know he had a website, i will check it out, thanks.

There is a link in this thread somewhere that leads to a page written by will prose. it is a good read! Go with that one on youtube university and make up your own mind.... Speaking for myself incl after what i read and learned here....Will is on a good spot... BUT there are to many differents...

Bingo, and this is why my house is idly for this....we come home and charge the ev's and start electric cooking...... The best roof is at 14:00 to 18:00. In summer time 15:00 to 19:00 This is also the roof i have the most room to place panels. Considering the time when we are stil at work and...

I have fuses on all levels. except individual cell level as you do with second hand li ion cells. Thanks for your explanations, makes al lot clear. But my inverter is just a stupid thing, min 42v max 58v, in that range he operates.... So i use the bmses to cut off the power under 48v, when the...

The panels on the south west roof: 6* 100wp 34,4v and 2.9A connected in 70v * 3 The panels on the east south roof are the same. I am planning to put them all in one controller. The reason for this is that from the local goverment i could not put all the panels on my south west roof(monumental...
