I’m suffering what I think is a common issue with this unit. I’m only getting about 5-10 amps charging from my car with the engine shutdown detection set to 12.8v. If I lower it to 11v etc, I can manage to get 15-20a but I’ve found no way to get 30a out of it. In the past I’ve had no issues pulling 30a with a redarc charger.
Is there a solution to this?
I have a similar problem - but not such low output as yours. My Orion TR-Smart 12/12-30 puts out 25A at start up, but then derates the current as it runs, ending up around 12-15A. I just tested it yesterday, while checking the temp of the Orion. Output dropped from 25A to 20A over 15 minutes, with the charger never getting about 70F (it was 30F outside). This derating of the output by the charger is clearly inappropriate. Is there any solution for this?
Settings? Input voltage?
I’d think the batteries don’t draw more power ?
Absorption voltage is 14.4, float 13.6. Voltage at the battery, via Victron BMV is 13.16 - or 57%.
BTW - this behavior was persistent on a long trip in October. While driving in cool weather I could watch the current from the Orion steadily drop even when the Orion is not overly hot.
I’d suspect the current is set to high for your battery, it starts gassing, reaches absorption voltage and the orion switches to float.
Ofc. only possible with fla or agm …
These should be charged with 0.1c over 14 hours, for a 30a charger you’d need a 300ah battery.
I am charging a 300Ah LiFePO4. So if I was charging at 30A it would be 0.1c, well below the recommended 0.5c.
Please make screenshots of the settings.
What is the input voltage while you drive?
The Orion will reduce the output current if the input voltage drops.
I had an input voltage of 14.0 when I was getting 14A from the charger, so don’t think voltage dropping is the issue.
I was able to get in contact with Victron support and am sending the Orion in for testing. Will be very interested to see what they find.
30f is clearly under the permissible charging temp for lifepo
