| |
| Some controllers/chargers have a "restart Absorption" option allows one to override Float and get more time at Vabs. Best use of this feature would be to look at the controller display a few minutes before the Absorption timer is due to expire. If acceptance is good let it go. If acceptance is too high give the bank another round of Absorption. |
| |
| If those approaches are insufficient, //Eternal Absorption// approach completely forgoes Float stage, forcing the controller to stay in Absorption by **setting Vfloat to Vabs**. This addresses the controller issues above. It will not address the insolation problem on a given day, but extended Absorption will help reduce damage from previous days of poor harvest. |
