Hi Everybody,
I have been using a set of 48v bsls for months without a problem. Suddenly, I have been getting infrequent BMS lost alarms. These can randomly be 2 in 1 day or 1 in one week. Virtually immediately (in a second or 2), I get a system recovery notice. Rinse and repeat. This doesn’t seem to affect performance otherwise.
I suspect one bsl module but it could be the Victron cable or the Cerbo. Each battery is wired to the busbars directly through a fuse. Wiring and fuses seem to be OK.
For now, I’m just ignoring the alarms. They seem to cause no harm other than being a nuisance. Or is this a problem?

Anything changed (slightly) in the wiring loom maybe? As this issue might be caused by electromagnetic interference
Not that I’m aware of. I’ve asked BSL what parameter I should look at with their PBMS Tools.
Hi @Fideri,
Please update Venus OS to version v3.53 and see if this resolves the issue.
Thanks @guystewart for the reply. Before I saw this, the alarms suddenly stopped without doing anything. It has been about 2 wks now and no alarm. I’m crossing my fingers. If they start again, I will upgrade accordingly.
I would suggest upgrading to this version pre-emptively, even without the alarms. Though good that they have stopped.
Ok, will do.
Before I upgrade, is any version after 3.50 ok? Would I get a large version with an upgrade as I use Node Red?
It must be v3.53 or later.
It’s fine to get v3.53 large version if you’re using Node Red.
