    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Thanks @houseofancients that gets me past the login screen? However, still can't get a BT connection. I've got it turned on in the functions, I have the BT enabled display module, I have Bt running on my iPhone. More tricks needed ??? ... and I'm very close ?

    Cells from Luyuan and Box/BMS from Seplos to Australia

    Sorry just noticed this! The Luyuan B grade cells are performing very well. I ordered some more (which had shipping delays), but both sets are good. I am happily working about 250Ah through them most days. No balance problems on either bank.

    RS-485 and CAN "features" with 2x interconnected Seplos v16 BMS and CerboGX

    Not quite ... as I understand it Andy had different sized packs and different Revs of BMS, so it was guaranteed not to work from the start. (Entertaining to watch though!). I have identical packs and the latest identical BMS build. I like your thinking on building an external gizmo, but it...

    What has happened to Luyuan/Amy Wan

    LOL. My SEPLOS box arrived a few weeks ago, and was mostly built and ready for the cells. Also, I've built one of these before so it was <AUTOPILOT ON>. Having said that, I did mix two of the wires on my Heltec active balancer and blew up one of the channels. I had to balance that cell manually...

    RS-485 and CAN "features" with 2x interconnected Seplos v16 BMS and CerboGX

    Hi Seplos Gurus, I have two Seplos Mason 280 systems where the V16 BMS are interconnected with RS-485 and also connected to a Victron CerboGX via CANbus. Pack0 is connected to the CerboGX via CAN, Pack1 is connected to Pack0 via RS485. I have noticed some interesting behaviour, which I would...

    What has happened to Luyuan/Amy Wan

    The cells have arrived. Well packaged and good quality as usual from Luyuan. Now installed, balanced and operating in a Seplos 280.

    What has happened to Luyuan/Amy Wan

    Yeah, I think my order is still in transit. I did get shipping labels and an apology from Amy some weeks ago. I think they just dispatched late and that's why I'm still waiting. At least , I hope that's the case lol. I'm not too worried about it, just a bit cranky that its been so slow compared...

    What has happened to Luyuan/Amy Wan

    No, I'm not sure how exactly to do that, all my comms have been with Amy. I've already been given a freebie from Alibaba because the dispatch did not meet their "guaranteed" dispatch date. I have also been given copies of the shipping labels, but these don't become active until the shipment...

    What has happened to Luyuan/Amy Wan

    No, the label is for the local courier (SCA). I'm not concerned that they won't arrive, eventually, so I'm relaxed about that. I'm just a bit annoyed about being ignored completely for 45 days. Regardless of the creation of a tracking number, they still don't confirm when or whether it has...

    What has happened to Luyuan/Amy Wan

    I received the tracking information on the 4th February 2023, however as of today (13th Feb) it does not show up as being underway yet, only that the tracking number were created on 4th Feb. I don't know when it was or will physically ship. Very frustrating. 280Ah cells were USD112.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    I would recommend that you don't fiddle around with any of those settings until you've done a real-time recording of the cell data during an attempted charge cycle. Then you can determine exactly why the problem occurs. At the moment I fear you are in the dark clutching at straws.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Right. It could just be a single rogue cell which is hitting the upper kneepoint early on the charge cycle. Get the data logged and have a look or post the file here.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    What has been the lowest SOC over the months you have been running? Did you previously go down much lower or has this 24% lower limit alarm been a regular thing since commissioning? As @brum mentioned, you need a proper full charge and top balance to happen. I would suggest that you run the...

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    I’ll try and get some pics of the wiring tomorrow ( had a gut full of it today ). Steve, Don't forget you need to log in to the BMS software to select the protocol. Then you can set it at the top RHS of the screen.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Yep, your wiring is incorrect, so you need to fix that. I will have a look at the inverter regarding the lack of ground connection, as that could still be a problem for the wiring. The reason I asked for the screenshot was to investigate what protocol/configuration you have running.

    What has happened to Luyuan/Amy Wan

    @sunshine_eggo Yeah, I'm hoping it's just holidays in the way. I was expecting some kind of communication when it shipped. I've had complete silence since I paid for the order on Dec 20th. I'm assuming it hasn't shipped.

    What has happened to Luyuan/Amy Wan

    Hi team, I placed an order for Eve cells from Amy Wan at Luyuan on 20th December and Amy Wan responded quickly and professionally as always. Since then I have been unable to contact her. Just no response to my messages on Alibaba at all. Some of them show as "read". I know we've had...

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Steve, the reason that the Lead Acid setting seems to work is because it does not require any comms on CAN, so don't worry about that. The issue you've got is that comms is not working. Step 1 is to make sure the wiring connections are correct. Step 2 is to make sure the comms protocol is...

    Give it a try without the ground connected.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Or more correctly 'should have'. There's a chance it might work without it, but it should be connected.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    CANBus (as implemented by SEPLOS) needs a ground connection.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Steve, if your LuxPower connects to the battery by CAN (probably the case) then you just need the CAN connections. IMPORTANT The latest SEPLOS manual for the 200A BMS is wrong, and the CAN L and H lines are swapped. I have informed SEPLOS about it but they are refusing to acknowledge that it's...

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    I don't know of any simplified instructions, only the user manual from SEPLOS. If you know about BMS operation, it's not too difficult to work through the software. I can imagine it's pretty confusing if you are not familiar with the operation of a BMS. Connections... You need an RS485 to USB...

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    I am using 2.1.9 of the PC software, BMS firmware 16.4, Victron Protocol V2.0. PC software V2.1.8 did not work for me, since there was no switch available.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    The switch works for me. I have it set to ON and have Charge Overcurrent warning set to 160A. The CCL is 150A until the first cell reaches the warning level, then it reduces to 10A. This is the expected behaviour.

    ??? Yes it's pretty messy on the outside, I'd hate to see it on the inside!! However, I have to admit it does most things I want to do, and value for money wise, it's hard to beat.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Hi CrossStreet, I investigated that, but decided not to go there since I cannot know what side-effects might occur from changing those parameters on the fly. SEPLOS have implemented range checks when you do it from their software which keeps the parameters within the ranges that they have...

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    @CrossStreet It's called "Single BMS 1.0C charging" as noted above by Chang. It is a function rather than a parameter and is found in the list of on-off buttons for the functions.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Solved. I was running V2.1.8 of the Battery Monitor software and Carl at Seplos advised that I should run V2.1.9 which allows me to access the needed function switch.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Hi Chang, I have the same problem with CCL being half what it should be. However I don't have the function switch you refer to. I'm running firmware 16.4 and Victron Protocol Rev 2.0. Are you running the same? Thanks

    Seplos BMS CAN values for energy stored

    @kenzo I came across your threads after observing CCL on my system ... At this stage I only have a single battery pack (second one on order), and I'm using V16 200A BMS hardware with 16.4 firmware version. Not the same as your system, however, I'm also seeing some issues with CCL values...
