Seplos Solar

Yup. Its a small 150amp fuse in a plastic case with tiny connectors. Its the only real subpar component of the battery that should be replaced with a class-T fuse and better connection points.

If they replaced that fuse with something more robust (high AIC), that would give them a leg up on the competition in terms of safety. Maybe something for Seplos to consider with the next iteration of this battery.

Not having proper main battery overcurrent protection internally isn't a dealbreaker considering that virtually no batteries on the market have it, and that the norm is external overcurrent protection. But if a fuse or breaker is included internally, it seems like a missed opportunity and a missed selling point not to include a properly rated fuse/breaker.

I can add a little more info about the Mason battery. I'm pleased with the robustness of the steel case, which weighs ~25 lbs. empty. The thickness of the steel is about 0.05", putting it somewhere between 16 and 18 gauge. The sixteen 135 AH cells weigh in at about 96 lbs., so the assembled battery will be about 125 lbs. The built in MIDI fuse has a 1,000 AIC rating, which I'd expect to be a huge obstacle to any kind of certification.

Do you know if seplos requires a rs486 or canbus connection to an inverter to work properly

they do not require it, but of course it makes thing better, both in monitoring straight from you inverter, as you balancing will be better

Can this be done with a computer until I get inverters figured out?

yes, there is pc management software for these bmses..

Hello all, I have ordered 2 of these Mason batteries as well and as I read in this topic there are a lot of strange things in their shipping procedures.

This is what happened so far:

Paid the order sept 10th 2021 to (hopefully their) German bankaccount
Confirmed by Adam same day
On the 25th sept he asked for my EROI number (that is a kind of taxnr in the EU)
The 4th of Nov I received tracing info. It is this: Chinese website , tracing number 8070938923

Chinese website but in google chrome translated to English. Last message on that site is from 21st Jan and it says: "Waiting to pay DHL in overseas warehouse" whatever that means. I tried to contact Adam several times now but the email address adam@seplos.com that I used all the time bounces.

Are there other Europeans that have ordered stuff from Seplos? Getting a little worried now...

have done so, but only their BMS'es.
I also know there have been issues with adamś account/mail..

you could try emailing Aaron, however be aware , the chinese new year/spring break is going on, there for it will take some time to get a response.

PM me, and iĺl provide you with his email adress..
make sure you include every thing in the email you send to him ( order nr. , payment proof, tracking nr etc etc etc)

I believe Adams new email is Adamhan@seplos.com, but the BEST way is to use Alibaba chat. Go to the seplos store on Alibaba, and use chat to communicate. It will be difficult until after Chinese new year festivities.

 

[RikH]

Ok @houseofancients and @Sanwizard , thanks for your replies. I'll try to send email at Adam's new email and info and via Ali. Then I guess I have to wait until they sober up. Hoping for the best...

 

[RikH]

Update; still no response from Seplos. Tracking site is updated to "Waiting for DHL truck to pick up the goods" though so there is still hope.

it is a national holiday in China until feb 10th , where just about nobody is working there.

My order from Seplos took maybe 10 days Fed-x. I communicated off their web site with Henry. The order did get lost in accounting after I paid. Henry got right on it and solved the problem. Very good communication.

according to seplos they manufacture the cells they use so im not sure if theirs are UL or not

Can you provide a source or direct quote for this info? To the best of my (limited) knowledge, Seplos does not manufacture any raw cells, and does not claim to, but they do sell cells under their brand name. Maybe this has changed

The response I got from seplos when I asked for the cell manufacturer was that they produce the cells and I was send a data sheet with cell info and all it has is their name on it

I believe you may have been mislead or misunderstood the person you bought the cells from. Sometimes there is something lost in translation/misunderstood with the meaning of "manufacturer."

When we originall had this conversation in January I reached out to Chris Ren at Seplos, They just got back to me and confirmed they are not a manufacturer of prismatic cells:

Hello Chris,

In the datasheet for the 100Ah SEPLOS C32100A Cell, it is written that:

This specification describes the physical, functional, and electrical characteristics of
the 3.2V 100Ah rechargeable lithium iron phosphate (LiFePO4) prismatic battery cell
manufactured by SEPLOS Technology.

Can you please clarify what is meant by manufactured by SEPLOS Technology?
I did not think SEPLOS is a manufacturer of prismatic cells. Am I mistaken?
It is not a problem if SEPLOS is not a manufacturer, I just want a correct understanding.

Thank you,
DZL

Yes, we're not a manufacturer of prismatic cells.

just posted the manual for the seplos bms that supports rs485 coms to voltronics/mpp inverters in the resources section

Outstanding! Thank you very much. Cannot wait to get to work on it.

 

[houseofancients]

Outstanding! Thank you very much. Cannot wait to get to work on it.

be warned, i understood from seplos it requires either their latest firmware or a hardware swap out.
also , the inverter should be connected to the port labeled as CANBUS.
unfortunatly i have not been able to test today, but this specific paragraph in the manual stems me very hopeful :

2.11 RM485andRS485 communication RM485 could realize communication between battery and inverter. And RM485 communication has different protocol according to different inverters. (Seplos RM485 protocol is compatible with Pylontech and voltronic protocol.) RS485 communication could realize data monitoring, operation controlling and parameter setting through computer or other devices via telemetering, telesignalization, remote regulating and remote control commands.

Hi RikH,

i orderd to Germany and have the same problem. My contact is Jerry and we write via WhatsApp. he responds quite fast.
Problem seams to be the company handling the customs part.
He told me, that I could get a refund or they would send a second battery/package.

I chose the second delivery and hope for the best now.

If you wish, I can PM you the mobile number for contacting him directly?

Best regards and hpoing for the best too,
Nerchi

PS: Does sombody know where the original thread with the 1000$ offer went? It seams to be deleted.

Up at the top of every page "new rules for vendors". Apparently the section that vendors should use was deleted, along with all the vendor accounts (except a few, not sure how that works)..

One of the worst unintended side effects is the removal of contact information that formerly was readily available.

I must admit, when I saw what was going on with Michael Caro, I figured this would happen sooner or later.

Try adamhan@seplos.com better yet, start a chat on their Alibaba site.
My order took a LONG time to get to my house in New York.
I do not believe they are still honoring the $1000 initial sale.
