Hi i have a dcdc 12/12/30 and a 100/20 solar controller, the solar controller works fine without the car running, when the car is started the DCDC kicks in but at a reduces amp input, for example solar input 10amps dcdc running total showing 20amps so the dcdc only adds an extra 10amps, i also have a BMV712 connected, maybe the setting on all three are conflicting?
The battery will only take however much current is required to bring it to, or keep it at absorption/float voltage.
is your battery voltage at the set charge voltage?
Hi,
I have set the DCDC absorption to 14.2, solar absorption to 14.2 and the BMV 712 charge to 13.3v when the dcdc runs in bulk it shows 14.2v and drops to 13.6v float the BMV 712 shows these figures as well as the apps.
