 You can start the loads **manually** (ie, start using the power when you have extra).  This is error-prone but is free and requires no equipment (except your own memory). You can start the loads **manually** (ie, start using the power when you have extra).  This is error-prone but is free and requires no equipment (except your own memory).

 In this approach the LVD is set just below Vfloat as above, but activation of the loads is delayed by some amount of time.  Observation of the system during charging will suggest how long it normally takes takes charging amperage to drop off (ie, when the system has surplus current). In this approach the LVD is set just below Vfloat as above, but activation of the loads is delayed by some amount of time.  Observation of the system during charging will suggest how long it normally takes takes charging amperage to drop off (ie, when the system has surplus current).
  
-Suggested delay for conservative opportunity loading == the time from [passing Vlvr setpoint during Bulk] to [completed charging].((settling to Float)).  This delay might be 2-3hours.+Suggested delay for conservative opportunity loading == the time from [passing Vlvr setpoint during Bulk] to [completed charging].((settling to Float)).  This delay might be 2-5hours.

 +Similar to the above, this setup looks like: [LVD or controller LOAD output] –> timer –> relay –> load
