 **The best time to run non-essential loads is when there is surplus current** over what battery charging needs.  This means **during Float, or after current has started dropping off in Absorption**.  For [[electrical:12v:deep_cycle_battery#lithium_chemistries|LiFePO4]] there is excess power any time after the bank has reached the intended charge state.  **The best time to run non-essential loads is when there is surplus current** over what battery charging needs.  This means **during Float, or after current has started dropping off in Absorption**.  For [[electrical:12v:deep_cycle_battery#lithium_chemistries|LiFePO4]] there is excess power any time after the bank has reached the intended charge state. 
  
-Opportunity loads should not be applied during [[electrical:12v:charging|Bulk stage]] since Bulk, by definition, means the battery is taking all the available current.((assuming no charging limit has been configured in the [[electrical:solar:charge_controller|charge controller]]))+Opportunity loads should not be applied during [[electrical:12v:charging|Bulk stage]] since Bulk, by definition, means the battery is taking all the available current.((assuming no charging limit has been configured in the [[electrical:solar:charge_controller|charge controller]]))\

 +**PWM controllers** will make [[electrical:solar:pwm_tweaking|most power during Absorption]] when voltage is highest.  Wait until current demand falls low enough that your loads will not affect Absorption.

 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.
