William, You can can set the sell voltage to 54.4 and that will help force a fuller charge prior to selling. Has worked for me on a site that had the same symptoms. You will find that these batteries can be 100% at both 55.2 as well as 54.4....due to the flat-ish voltage/soc curve. Hope that helps. Happy Friday! Kirpal@oregonsolarworks
