Newly installed Orion xs 50a stays in absorption mode and does not have bulk timer setting.
I have a new xs Orion 50a charger. Previously I had a 20a competitor. I upgraded wiring for 50a.
I installed 20a back to verify wiring worked fine. It did. Configuration is truck to 15 foot teardrop camper.
After installing new unit:
Upgraded to latest firmware.
Set to lithium battery manufacturer recommended setting 14.6 v no float. Batteries are 2 12v 150ah wired in parallel. Both brand new.
The unit only goes goes into absorption mode.
Working with distributor I discharged batteries to
30% them charged to 50%, them 80% using 120v Victron lithium charger.
Same result, but the current varies. At 30% it pulled 30a but stayed in absorption mode. This was true at all SOC’s (charged via 120v charger up a point where current starts decreasing to levels you would expect in absorption mode.
The manual references a bulk charge time setting, which I wanted to verify /try setting as a troubleshooting option. I do not have this setting.
Online I found a picture a guy posted from 5 months ago. I do not have this setting option.
Eco-worthy batteries.
Voltages are same at battery, camper connector, and battery when charger turned off.
Have varied between load and no load on batteries
When turned on charger is 14.6 because it is absorption mode (voltage constant) while delivering up to 30a.
Ludo, did you note the pics? The bulk time setting is grayed out and bulk time cannot be set. Whether hooked to batteries or not. Any ideas on that? Firmware issue?
You can not force bulk to carry on for a defined time. Bulk starts when the charger starts and bulk ends when the battery reaches the absorption voltage. If the charger is powerful compared to the battery size, or the battery is full bulk will last a short time, this is perfectly normal. The only abnormal time bulk lasts for a short period is if you have a poor connection from the charger to the battery and voltage drop, say the battery is at 13.4V and the charger is at 14.4V, bulk ends because the charger gets to 14.4V (if that is the absorption voltage) but the battery is not being charged fully. In this case, use a multimeter to check the voltage at the output of the charger and at the battery terminals and rectify the voltage drop.
