Where the hell can we get the cheap EG4 or the Trophy 48v lifepo4 rack batteries in Europe for that nice price like in the states?

[ZOR BA]

I've been googling for days and annoyed why we here in Europe have to pay an average of 500€ more for a 48v rack battery compared to the prices in the United States.

 

[Marcelvanrooden]

Same problem here. but you can try https://www.europe.sokbattery.com/
Dont forget that the prices in US are excl. TAX.

see comparison by Will

Move to the states. Duh.

Not sure what country you are in, but Fogstar in UK are soon to launch a battery pack for European customers, see...

Help us design a rack-mounted system for the UK

Ben, i think the issue wont just be with the shipping, when they get to their destination, how will someone be able to pick them up and move them? However if you also designed a self build pack of four boxes of cells and one box containing the rack mount (or wall mount?) then it becomes more...

BTW: I have no connection with the company, apart from being a customer. @Ben@Fogstar is active on these forums.

Greetings from Belgium, I decided to go to I diy Eel - Seplos battery. With the Eve 305ah cells. 15kw for about 3000€.

Hi, @ZOR BA Where did you buy your Soplos batteries? Are you happy with them? I am in Italy and about to build an off-grid solar system. Any suggestions most welcome.

eel is NOT the seplos kit...

 

[mickenorlen]

I contacted eel and they suggested me 51.2v 15Kwh EEL Server Rack LiFePO4 currently for 3079$ = ca 2850€. Not sure if the strange voltage could cause any compatibility issues? Or if there are any more hidden fees upon import to Italy..

Then I also saw this seemingly more standardized option that cought my interest for 4158€:
Kit SP24 Axpert Max 8.0Kw 48V Off-Grid Inverter and 2 x Pylontech US5000 9.6Kw

What do you think about these options? Any other ideas? Thank you!

Or you could contact docan or qso(both have EU warehouses) they all are selling rebadged seplos box..
Eel is selling a copy, quality unknown

As for me, I order a real seplos box ( 485 euro) and 16 cells (1950 euro) .
Wait 45-60 days and be done

Not sure what you mean by 'strange voltage'... 51.2V is standard for 16-cell LIFePO4 battery packs (i.e. 16 * 3.2V per cell). It is actually Pylontech that have the 'strange' (= cheapskate) configuration of only 15 cells (=48V).

 

[mickenorlen]

Thank you so much @houseofancients, I would never have found these options myself. I contacted them as you suggested.

@SeaGal That makes sense! Thank you for the info. I'm just getting started to understand these systems. For now I'm just hoping to be able to learn enough to order some good components and then mb hire an electrician to help me connect everything.

- Pylontech spec sais >6000 cycles with 10 years warranty, while the standard CATL/EVE cells state >3500-4000 cycles and 5 years warranty. So for equal cell quality I would have to compare to EVE A+ cells (although warranty not specified). That means either

230Ah: 11.776 kWh for ca 1650€ (16x110$) => 0.14€/Wh (+ box for 500€ => 0.175€/Wh)
290Ah: 14.848 kWh for ca 2100€ (16*140$) => 0.14€/Wh (+ box ca 500€ => 0.175€/Wh)
Compared to pylontech 9.6 kWh for ca 3000€ => 0.31€/Wh

- Pylontech seems to have a built in BMS? Mb thats why they have 1 cell less?
- If buying the EVE cells I guess I should add a BMS as well and consider it for the cost?

I don't think a BMS would be a reason to have one less cell, since there are 16S BMSs. Is the Pylontech a different chemistry than LFP?

All battery rack systems will have a BMS, nothing to do with 1 cell less.
If you are DIYing you will need a BMS. No questions.
Also take a look at Fogstar that I linked to earlier up this page

 

[mickenorlen]

I see! I didn't actually find the battery boxes/rack systems listed at docan or qso so I'm not sure if there is some deal with the BMS included.

Yes so Fogstar from UK (looking at Grade A cells):
EVE 304Ah LiFePO4 (currently sold out) ca 3000€/15.565kW (16*154.99£) => 0.1927€/Wh (+ 600€ box 0.2312€/Wh)
EVE LiFePO4 280Ah (currently 10% discount) ca 2500€/14.336kW (16*129.99£) => 1.74386€/Wh (+ 600€ box 0.2162€/Wh)
SEPLOS Mason 48V 280Ah DIY Battery Kit (14.3Kwh) 500£ = 600€ - This box includes BMS and everything you need!

Then there is also the full kit for 280Ah
SEPLOS Mason Kit and x16 Grade A EVE LF280K Battery Bundle (15% discount) ca 2800€/14.336 kW (£2,396.00) => 0.1953€/Wh

So with the discount this kit seems like a really good deal on par with the options above!

I just realized they have a "wholesale" store as well. But with the above discounts prices seem the same. However, I'm not sure about shipping and import from UK=>EU (Italy)

I guess I'll contact them as well and see. Thank you for the suggestion

I was actually thinking of their battery rack...

Fogstar Energy Server Rack Battery 48V (5.12kWh)

UK-designed Fogstar Energy SR51.2V Lithium (LiFePO4) Server Rack Battery with heating, pre-loaded inverter protocols, LCD touch screen, 16 Grade A EVE Cells, a DC Rated Breaker and an 8 year warranty.

www.fogstar.co.uk

but, yes, lots of options.

 

[mickenorlen]

Interesting. I'm not sure what is the benefit of the battery rack compared to the mason kit? From what I can see:
- touchscreen (also present in kit although might differ)
- pre-loaded inverter protocols (seems also present in kit)
- some edge case heat management.
- Better warranty 8yrs

Fogstar states 1 year warranty even on grade A cells :O
Docan gives 3 yrs
Qso 5 yrs

Also I just found batteries rated for 10 000 cycles at Qso! Seems very interesting!

 

[mickenorlen]

In the end I got the Seplos Mason DIY kit + 16 x EVE 280Ah grade A 6000 cycle cells from qso who offered best price and warranty. I've learned that 10000 cycle cells probably isn't worth much for residential backup application due to inevitable calendar degradation.

Thank you so much for your guidance!
