absorb is set for 58.8V for four hours.
The system is 48 V
I have it set for lead acid batteries which is what I'm using
WoW ! Then, I wonder what is going on ?
Is it possible that there is a voltage drop while in Absorb that would make the BCM think that the battery voltage is actually lower than the charger is putting out at its terminals ?
Do you remember the voltage the BCM needs for that setting ? Sounds like 58.8V should be good.
Remember that the BCM doesn't know what the battery temperature is if the charger is compensating that set-point voltage.
OTHERWISE, maybe the BCM is not reading the voltage correctly and you need a new one ? If so, you could call support and tell them I sent you.
Bob and the group,
Still have the led LED on, battery is in float condition already (11AM), nice bright sunny day here.
I was thinking... If I were to connect the BCM to one of my bench power supplies, I could easily fake any voltage
condition that the BCM might want to see
So, if I keep with a 48 V battery, what would be the voltages needed to convince the status led to do their thing? And what would the hold time for any particular set point be?
I've had this one nailed to the garage wall for a week now, and other than seeing the moving LEDs move a bit, the status LEDs remain in red
Do you think this would work, bob?
