Achieving full charge with solar system
Here is a question for the learned solar system folks.. I have a Tracer 40 am MPPT charge controller and a Xantrex 20a smart charger. Currently, the Xantrex is across the batteries. I do have maste...

Are you charging at 14.8 volts?
I assume so, default output of the charger
How many hours in absorption?
Can’t tell, no display.
If you get down to 2 or 3 amps they are as full as they are going to get.
I have used the Xantrex and a cheesey Canadian Tire automatic charger, both showing “full”.
The MPPT external meter shows up to 90% and then falls back to 60 – 70% within an hour of disconnecting the charger.
I also have a 500amp shunt and digital meter, shows same voltages.
Are you verifying 100% with a quality hydrometer?
Going to get a hydrometer after work!
