I just updated a victron 200ah LiFePO4 to v1.25 firmware, and I'm getting E-SL24 and E-SL2 error codes. Additionally, VictronConnect says "Alarm Charging disabled & Discharging disabled" and shows no information for cell voltages.
It suggests re-installing the firmware update, but product info won't update, and says its already on the latest. I tried restarting the controller.
Thanks!
Is this the same ancient battery you mentioned here: https://community.victronenergy.com/questions/114782/victron-bat5214130410-circa-2018-self-discharging.html
@kevgermany no, I wasn't able to get that one to do anything, our records indicate this battery was charged within the past several months, and was reported as working happily in victron connect at that time. We've had a lot of turnover during covid, so records aren't great. I'm worried this one stopped working when I let it firmware update from Victron Connect before I checked on its status.
I'm supposed to check on the status and maintain about 8 of these batteries (most are from the same batch), but I haven't used Victron gear before, so I'm learning as I'm going. You'll probably see me posting more questions going forward, if it helps I can identify the batteries by number, but so far most of them seem to be working happily (have a few that need their cells rebalanced but otherwise seem ok)
Hi Seth, I quickly checked with engineering, and I'm afraid the best is to get it replaced/returned: if you are a direct distributor, make an RMA - and otherwise contact your distributor.
Aloha @mvader (Victron Energy) , thanks for getting back to me!
I'm not a Victron distributor, I mainly assist hawaii based academic labs in procuring, shipping, and servicing one-off scientific equipment.
I apologize, but I've been unable to figure out who our distributor for this batch of batteries would be. This is work I'm doing for a lab, and unfortunately their asset records are sometimes lacking. You might think scientists would be good at accounting, but I'm learning its quite the other way. They /think/ this got this particular battery shipped directly to the lab by a corporate donor (as part of a research grant batch), but honestly I'm not sure.
One additional complication... we're 4000km from the nearest victron distributor, did I mention the battery is in Hawaii? 8-D
Is there any possibility of doing an e-rma directly to victron? I've shipped large lithiums before, and have experience crating them appropriately for ocean shipping. I know this is irregular, but thought I'd check.
hi Seth - any recent updates to this issue e-sl24 fatal error, I also have a 200 amp battery, from 2021, one is now showing this error, with the fireware updated, not sure if that caused the issue or not, the other battery does not even show in the app. thanks David
Victron 330ah LiFePO4: E-SL24 and E-SL2 error
Last week I received a brand new LiFePo 330Ah Battery (SER:HQ211349QY3).
Using VictronConnect it was upgraded to the newest firmware and for the past week it worked fine, showing all cells at 3.28V. It is waiting at home for installation and I have checked it regularly over the past week.
Now, after one week, it suddenly showed errors SL-2 and SL-24, just like this similar post (https://community.victronenergy.com/questions/118141/victron-200ah-lifepo4-e-sl24-and-e-sl2-error.html) on the 200Ah Battery. Voltage measured with Volt-meter is 13.15V
I have mailed my dealer dealer asking for corrective action, and will wait for his response.
After some insistence, an appointment could be made to visit the service department. It was found that a reset of the microprocessor did not solve the problem and the battery has now been exchanged for a new battery (SER: HQ2113UGPCX).
This solved the problem as should be and I assume that this is a rare case of bad luck
