question for the solar gurus
Trailer is stored and not being used at present. The solar system is active and keeping the batteries charged up. Every morning it goes into 14.4 volts absorb and later 13.7 float. The batteri...

Wow, thanks for all the great replies.
A little more information I should have shared. The solar is dedicated to a Xantrex Freedom SW 3012 inverter/charger and the only parasitic load I am aware of is the monitors for the Xantrex and the Morningstar MPPT-60 controller. The inverter is disabled at present The controller is set on a factory setting for AGM. It goes into Absorb for a minimum of 180 minutes each morning.
There are seperate house batteries that are charged when the inverter is on that would have a parasitic load

" Charging should stop whenever the charging amps drops to less than 0.5% of the AH rating. For example charging should be discontinued for a 100 AH battery when the charge amps drops below 0.5 amps. Many solar chargers are not capable of making this determination. Most will automatically hold the 14.3 charging voltage for a couple of hours even if the battery is fully charged and the amps drops towards zero."
This is what I read could happen and wanted to try and learn how to avoid.
As ya'll can tell I tend to overthink things but I really want to learn all I can about the system.
