My Seplos kit arrived last week and I've put it all together with some Xuba 280ah cells. I thought I would give some insight and some pictures as to the process and what I found. Firstly the cells came first, they were from Xuba and cost $2112 USD delivered and duty paid to the UK. These were...

They've corrected that now. They added a video to their facebook showing they are now putting everything inside foam and into a box. So I cant see any issues on that front anymore. And yes, super buff

This is what they sent me

Yes there is. It's not in the kit. Nor is there a guide on where to find it. I had to ask Seplos and look at YouTube. It would be easy to throw one in or at least a link to where it could be found

I lifted it before I put in the cells. I got a cheap dolly with wheels and finished it on the floor on the dolly. Now I can just roll it around.

It's resolved. After much troubleshooting it was determined my BMS was broken. They sent me a new one, problem solved! No issues since

I got a £12 one from Lidl. Its just a bit of wood on wheels. If you can guy some castor wheels from a shop you could make your own in about 5 mins. Honestly, I'd put the data cabinet on top of the Seplos. I think it could potentially survive a nuclear war given its construction.

There is a function on the BMS to set it to speak to the sofar inverter correctly.

As an update Seplos are sending a new BMS to me. Should be about a week to arrive. That SHOULD fix the issue (hopefully)

That's correct. I'm not sure if it's the right thing or not. I share your concerns. That said the bus bar is aluminium, not copper which has been plated. I'm not sure on the reason from Seplos, it isn't explained in any way.

My old BMS is 48200-1101-10C-SP16-16S No idea on what was actually wrong. After all the troubleshooting with technical support they concluded it was a dud board and sent out at the latest model 48200-1101-10E-SP76-16S

I set the capacity to 280ah this morning at 100% charge. So that should be sorted now. I think my issue came from the fact I had to swap the BMS as the old one had a fault. When I did that I just swapped out without fully charging/discharging the cells first time round. So it probably messed up...

I'll have to investigate. I'm not sure what would happen if I pulled the Comms cable. I'll try to charge tomorrow without it and see what happens!

Yeah. I might raise the value of the storage to 340ah or something

Yes I just get a time out message for both. Any suggestions?

You'll find that it's not charging it at all after that point - I have the same inverter. It just won't discharge until 4.31am. have you logged into Solarman to check the charging/discharge numbers? Looks like the battery charge current drops away

Also do I really need to connect to the BMS to use it? Or can I just use as is? I get people want to see what's happening a tweak settings. But is it really needed?

The BMS should turn it off at 100% charge as should the inverter. Perhaps it's going into absorption mode?

please go on...

No it's been down to 15%. This is why I am just flagging it now, as it's a new thing

Battery monitor 2.1.9 is only for the new model BMS. Don't use it on the older ones or it won't work.

This is what worked for me. I had to buy the adaptor from Amazon and I reused an old Ethernet. I can now connect. Any advice on BMS settings would be appreciated.

Are you getting any alarms on the Seplos?

Any one like this will work - https://amzn.eu/d/2fXmrzu they are all the same. You only need 3 wires

So do you think it's worth trying @brums idea and setting it to 300ah+? Tricking both the BMS and the inverter to fully charge?

I'm also getting this (amongst other) errors. Any idea on its cause, or a fix?

Can anyone help me out here? Having the same issue. I bought the Mason DIY pack and its not connecting via an RJ45 adaptor. I know the adaptor works as I've used it my Pylontechs in the past. I just get the "Time Out" issue

Battery is reconnected. Changed the cable and restarted the BMS. Now logging in real time. Hopefully I'll have the log tomorrow

So I need to build a new cable. According to Seplos my cable that works with Pylontech won't work with their BMS... The connector will arrive tomorrow then I'll make my own Ethernet out with the right pins. Hassle

After a few days of logging I managed to pull a big file and chart the data. This is a full day from normal running, discharge and charge cycle. I can see some differences in the cells - but at those voltages they are basically fully empty anyway.
