No, not at all. The software lacks a lot, the balancing is not really working. Check Andy's series about the fraud on off-grid garage in australia when they had shipped 3 year old LFP cells to him in this summer - qr code said built in 2019 . And there had been more isssues . No, not a monday built BMS cause he had purchased 2 differet SEPLOS batteries, the 6,9 kWh Mason full diy kit incl. cells and the bigger one without cells for the EVE LF280K cells. Same issues and struggles.
I have seen many unnecessary disrespectful messages on this post in fact I think that your observations are very professional and I would strongly agree on the subject of the bus bars, being a mechanical engineer, I did cringe watching Ray using the toque wrench on those, in my opinion, inadequate fastening screws. I'll be looking forward to your developments on the usage of this BMS as I am now constructing my PV system with a temporary 5.1kWh "microwave ready" battery for testing purposes to then progress to building my own 300ah one having just spoken to Jenny wo about the cells thanks to the generous input of our friend Ray. Thanks again for sharing 🙏
I think the Seplos BMS, with intergrated shunt and pre-charge resistor, is an excellent BMS, especially with the intelligence to communicate with other BMS's in a string. I currently use HELTEC/JK 200/2amp active BMS's, which will be replaced with the Seplos if they test well. I look forward to your testing and integration.
Thanks for posting this, I agree it looks great but I wish the connection points were stronger. Can I ask how you are finding this bms in production? Does it have a Bluetooth or WiFi connection and app etc? J
I think you will be fine with the screw connections. When you run the wire, Dont let it be stressin on the board itself. Also I think you can run 3 wires from each side of the connections. You should be fine for carrying current. Most of the ones I see are doing 100 amps or 200 at max. You should be fine without any modifications. Might want to consider that because of warranty purposes. Just in case. Because they may not honor warranty if you make modifications to the product.
The current shunt would be much better as a separate shunt with just two small gauge sense wires brought into BMS board. You could unsolder it and provide your own separate shunt.
Hi, I have this BMS to control 16x 280ah lipofe2 battery pack. So do you know what is the ampere of a circuit breaker to protect my battery? 200ah dc circuit breakers doesn't exist and I don't think that's the ampere to consider (200)
2:01 I believe this was designed for use by commercial battery packs manufacturers. And those post you see are for copper bars inside the battery pack.
Very nice video. What did you do concerning the length of the balance leads? I'm looking into my own DIY project and how my batteries will be situated, I need some longer leads. Thanks.
@@administratorshan So far absolutely no issues. Difference in length is negligible to make difference. This is in regards to other BMS that I have. All measurements are taken with Fluke meter that has 4 decimal points.
Better check the seplos website and be aware that support of canbus is not enough, cause each inverter manufacturer has different can bus dialects. Growatt has even 2, one for their offgrid series (1.05) and 1.01 for their grid tied series SPH. Canbus is not enough.
@@odedeyidamilare in order to get mpp solar to work you need to order a specific version. and you can't update it back to CAN bus, unless you send it back to them. anyway, I've order 2 to test them with mpp solar inverter.
Unfortunately unplugging and plugging back in the COM cable whilst the BMS and inverter are both turned on kills the BMS. Has happened to me twice. Not sure why.
After installing mine that I bought from minerals on AliExpress, it goes through the light flashing sequence than nothing they LCD screen goes black the lights go out. Any ideas. I guess I need to install the battery monitor software, purchase a USB to RS-485 adapter and cat 6 cable.
With the system as large as you have, you should just drop the money on a Batrium or REC-BMS. This way you don't have to run the current through the BMS.
@@DMIINC2013 What function to the integrated solit state relay have? Is the Seplos alone enough or do i need a relais additionally for cutting of the battery like REC-BMS has it?
I have so far received twelve junk emails from third parties at an email address used for only one thing: filling in the enquiry form on the Seplos website to request BMS manuals. Posts on diysolarforum suggest this is not a one-off occurrence. DO NOT fill in the enquiry form on the Seplos website unless you're happy receiving unsolicited emails from third parties such as EveryChina as a result.
@@DMIINC2013 the latest NEEY top balancers are working quite well after Andy from the channel off-grid garage had kicked them in the ... for several times. Now they seem to have gotten it right. Off-grid garage is an australian channel - and andy is a german emigrant who is investigating these products carefully like the SEPLOS products and JK BMS and some more.
