Looking for ideas to troubleshoot my alternator charging setup. I replaced a ML-ACR from the AGM setup with 2 Orion Tr Smart 12/12 30a in parallel with the new BattleBorn Lithium batteries.
I took the easy way out and re-used the 2/0 wire run by the original up-fitter from the Transits main terminal back to the power cabinet (10-12' run). There I am using a small busbar to split off 2 50a fused 6awg input wires to each Orion Tr Smart 12/12 30a. Then from the Orions I go to the main busbar.
The Orions will charge for 10mins in Bulk, then flip over to Absorption and not provide any incoming charge. After 10mins the units will sometimes begin charging again while still showing Absorption even though the SOC is at 50%. When the units do begin a new charge cycling on their own, it follows a 5min on, 5min off pattern.
If I remove the jumpers to power the devices off/on, I will get another 10min of bulk charging before it again cycles to Absorption and no charge.
I see input voltages in the 13.8-14.2 range during all this. I have disabled one of the 2 units and see the same behavior, just half the charge amps. I have also turned off the Smart Solar MPPT controller so only one charge source is contributing. My only 2 thoughts are to try and connect via the Ford Customer Connect Point vs direct wire to vans system and/or wire the Orion output directly to the battery incase there is something at the busbar contributing to the issue.
Thoughts?
