why do you choose 3 phases for battery setup? high output power demand ? or regulations where you life ? do you choose the decentralised batrium watchmon due to the need of high balancing power ?

awesome setup jochen. iam planning about the same for my house, but with 1 Multiplus for 1 phase first. maybe adding later another 2 they can be linked together later as i know. planning on 200Ah or 280Ah 16 cell setup first and extension + 1 or 2 banks later. i think you choose watchmon 4 for...

does any1 have infos about LiPoFe batteries are produced in europe in the near future ? or are these more NCM cells ?

does these cells have a QR Code and Warranty ?

our company was involved in the UL certification topic for laser marking products. the thing is in general the company has to supply a batch of series for the product to a certified institution, this institute is going to test the product and confirm the UL conformity, or if not, they give a...

As i said, for CE a company is not forced to do tests to get this certification. While for UL a company need to do tests and pass test requirements. thats why very less products have UL. UL has very strict requirements.

Good to know, can you please upload pictures of the setup ?

CE can give the company itself. With this they confirm to comply with european regulations of the product. the company dont need to do any tests, they are forced to publish test reports if any accident happens with a customer with the use of this product. therefore any playing tool from china...

CE = China Export :)

yepp as jejochen told, they told me the same. which one you ordered jochen ? 200Ah ?

Deligreen claim the 200Ah cells are Grade A cells, but not certification. i dont know. i think still better deal than BLS as deligreen gives 1 year warranty on their cells.

thx. i truly think 120Ah cells (like the one Will ordered) are degraded used cells ... and 150Ah or 200Ah cells are new cells maybe unqualified (less capacity)

which one you have ordered ? 150Ah ? is the dmc Code scrached off ? was the terminal scrached (used) ?

marc you ordered also from BLS ? and your cells got a DMC Code for indentification. But this shows, one time you got wiped cells and one time new ones with a code, from the same supplier ?

great video. capacity test and impendace of bad cell would be great to know.

thx for your perfect explanation. its clear now.

how many of these cells would you set in parallel max. without any "big" issues ?

what does this mean jimmy (do go out of balance towards the top end of the charge cycle ) does this mean, they cannot be used in a power bank ?

iam very excited about your results and thx you for that very helpful information Maast

thx Will i was just thinking if Will can review those kind of cells as there are so many replys (pros and also so much cons here in the forum). i really hope they dont sent you the best ones if they read this stuff here.

so the cells just perform well Maast ? how many cycles ? how many months / years ? any problems ?

awesome description johan, the good old roloff matek :)

haha nearly the same post at the same time, barb :)

thx would like to see more how these cells perform. as we need more reliable information on these alibaba and aliexpress cells

thx for your hint. your right. the only thing is, deligreen is larger with more reputation and reviews and comments as BLS. but overall its the same level of risk actually.

a little bit offtopic (not BLS related) i got an offer on deligreen alibaba on 200 Ah - 16 pieces for 1480 USD including shipping and taxes and stuff. 120Ah - 16 pieces for 1194 USD including shipping and taxes and stuff. IMHO much better offer than BLS. as deligreen on Alibaba is more...

this seems to be a more reliable source.

thx... so i dont know.. there are a few good reports about these batteries... also good voting and replies on aliexpress itself. but some with really specific problems here.... is it just commenting on high level. or are these batteries not usable for household powerbanks due to risks.

how many do you have keith ? and do you had any bad one in that batch from bls ? you just ordered one batch, or multiple ?

hereby i have done a drawing of the components and supply for the future battery bank integration. maybe this one makes it more clear aswell. can you please have a look and comment if you find anything non-working in that configuration. thx

Thx so much for your input, your interpretation is completely right now. i can feed into the grid it is allowed but i only get 6 cents. i dont want to touch the solar grid tie inverter huawei STL12000 as it is pretty new and the system was installed by a solar company (warranty) i searched a...

thanks for your feedback and information svetz. maybe you got me wrong. i dont want UPS or power backup functionality when the grid is down (here in the region its pretty seldom to have no power from the grid). so if this feature is complicated its absolutely not necessary to implement. i will...

as i understood, it need this kind of inverter / charger : https://www.aimscorp.net/4000-watt-pure-sine-inverter-charger-24vdc-to-120-240vac-output-listed-to-ul458.html but i dont unterstand how to control that device to charge batteries or to discharge to feed the house power drawings.

Hi everyone, iam very new to this topic, i probably have seen nearly all of Wills Videos very interesting, but i see only OFFGrid Setups with the batteries and iam trying to get to the point if its possible to add a battery bank explained in the videos for on ONGRID solar system in addition. I...
