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...

If the battery is fully charged and stays that way, blasting the battery at 14 plus volts could shorten the battery life. 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.
There is a reason float voltages are set at about 13.3 v.
