New OEM ford starter battery installed a week ago by ford dealership. The van went in for 60K maintenance service package, including testing battery connections, load and resting voltages and ensuring they are to factory operating specs.
Thanks- The renogy dc50s is connected to the CCP2 (ford transit Customer Connection Point) on the left side of the driver seat- It is as direct connection to the starter battery as it can be.
Everything you mentioned checks.
I've tested the batteries individually (even tested an agm one separately and changed the profile to agm). Somehow still getting the same result. I am beginning to think something went wrong with the way Ford alternator manages the voltage between the starter...
Seems odd the house battery can only be charged from the alternator when house battery is nearly completely discharged
All lights on the renogy dc50s is normal - steady red for alternator charging, steady amber for service (aka house) battery and steady blue for battery type (lithium)...
Neither the DCC50 or 1250D has settings to manually modify the amperage.
The DCC50 does limit alternator charging to 25A when solar is connected, but charging from alternator still only pulls 0.24 amps, which means it is really not charging from the alternator.
Are you saying I need to run down the starter battery to 12.5?
It is still odd that Renogy DC 50S 'cut in' voltage from the starter battery is 13.2, when it is already maxed out at 13.00. Thus, it will never be triggered with this logic. Renogy should have set the 'cut in' at 12.5 in order to...
Solved! Victron Orion standalone DC DC charger solved the problem- The Victron has better software working with the alternator/starter battery. Both the Renogy DCC50S and Redarc 1250D failed to work.
I don't mind buying a separate mppt from Victron- which I will do- since the Victron just works.
Yes 14.5 is normal- it drops to 13.1 volts when the renogy dc charger activates. 'Cut in' or threshold for the starter battery to charge the house battery as programmed by renogy is 13.2 volts.
Hi,
I've searched and searched for similar topic without much luck.
I have a 2019 ford transit 350 XLT with traditional alternator, renogy dc dc 50S mppt combo and 3 renogy self heating 100 ah lithium batteries setup.
The starter battery voltage is consistently at 14.5 at idle. The starter...
So how do I get the renogy dc charger to charge the house battery as it is supposed to?
I've tried charging at full, 75%, 65%, 35% house battery state of charge and still no luck triggering the charging threshold.
