Victron blue smart charger 24/12 not charging, no current

[WilliamC]

I looked to see if there was a Victron forum. Sorry if this is in the wrong place.
My charger is not charging. Shows 0.0 amps current. Briefly shows 0.8 amps then back to zero.
When unplugging the charger completely then plugging everything back in the charger briefly goes to bulk, then quickly to absorption.

I checked the 15 amp inline fuse and it is good.
Back ground
I have (2) Big battery 24v 170ah batteries in parallel. Both batteries connect to buss bars with inline fuses. The charger leads connect to the buss bar.
I also have (2) EG4 24v 200ah batteries in parallel. These connect to a separate buss bar with inline fusses. I have also tried charging these batteries by connecting the charger leads to the buss bar.
The charger is recognizing the battery voltage, but not sending out amps.
I get the same results for each set of batteries which leads me to believe the fault is with the charger.
I tried erasing history in the charger. Didn’t help.


We recently had a prolonged electricity outage, and both sets of batteries were in use. my smart shunt shows both batteries at about 50% so I know they need charging.

Do I need a new charger? Would like to stick with victron due to the Bluetooth connectivity between components.

Has this charger ever worked for you? or is it new? Have you checked the settings?

 

[WilliamC]

Q-dog I got the charger 4ish years ago. It has worked. But I don’t monitor it regularly so no idea when it quit charging.

Contact your vendor? They may have troubleshooting tips, and It may still be under warranty.

does it have adjustable settings? if you put a heavy load and drop the voltage does it charge. the bulk to absorb tells me it think its fully charged for some reason.

It would be great to see the settings page.
The 26.34 V on the report is very close to the voltage for "storage" mode - maybe that's what happening.

Settings

 

[JanisD]

Here we see that Low current mode is enabled. Any reason for that?
Have You tried to restore the factory defaults and go trough the setup procedure afterwards? It could drop some faulty settings.

If this doesn't help, I would go with Q-Dog's suggestion to contact the vendor (or closest Victron dealer) - most likely they will lead You trough the test sequence or will tell where to send the charger for testing.

default Li-ion settings are

bulk 28.4v
2hr absorption (repeated every 7 days)
Float disabled
Storage 27v
Re-bulk current disabled

(We should be seeing 28.4v while in absorption stage)

Stupid here but are lifepo4 battery charge mode enable.
If the bms is shutdown the charge function.
Than you see this to on the victron .
It have a volts but no charge.

You have to test the charger it self
Disconnect the cables and use a 24 volt light ball or somting els and test the charger.
And see than if the Victron do somting
No amps meen no lights will function.
