Daly smart bms setup issues

[Farmgirl0527]

Hi, any one on here familiar with daly smart bms., I have 2, 150 and 200amp and havi,g problems setting them up. Daly tech no help, and their instructions leave out a lot. Have a 16s, 48v system 280ah l8thium

There are quite a few Daly threads over in the BMS forum https://diysolarforum.com/forums/bms-battery-managment-systems.23/

Maybe a mod will move this thread there.

What are your actual issues, I have the 16S,100A unit which worked out of the box. IIRC I had to tweek the cell voltages to suit my rather worn cells but it was a while back.

Several, can't get beyond 54v, getting a high cell volt alarm, but a volt meter shows still below cutoff voltage, once it reached 54, it stops all current in and out. I Can do screen shots if you like

 

[Farmgirl0527]

I've read a lots of posts. But not on settings

What do you have the cell limit voltages set at?

It could be one cell going high due to being well out of balance, screenshots would be handy I think.

I can check my settings when I get home from work tonight (it's 7:15AM here at the mo).

All my cells test fine. The alarm showing high is false, actually all read 3,29 or 3.3

Lastly the BMS shutdown when in alarm or reaches a cutoff point

It does seem to think you have an over-voltage cell, are you saying that that high cell is actually OK?

Check your wiring carefully.

Check the cell voltages actually at the BMS connector.

Yes, the high alarm is on, but when I checked the cells they were fine. I radii all my sense leads and can't figure it out

@Farmgirl0527

Which firmware version has your BMS (software version on the first page on the APP).

 

[Farmgirl0527]

Version 1.96

 

[DiySolarU]

Hmm...

You have a DALY Smart BMS 16S?

Then the software version is something like this. Can you take a screenshot?

 

[Farmgirl0527]

Right,now I took them off line to do a balance charge. Probably a week before I put them,back. Once I do I'll send a pic

 

[DiySolarU]

If You have older Firmware Version, thats the problem. I have put a working firmware in the Resources section.

 

[Farmgirl0527]

Thanks, I'll check it once I rebalanced my batteties

 

[Farmgirl0527]

Found an old screenshot and is the same as yours

My new Daly 250 16S switches to Lithium Titanate on its own!
