 Some [[electrical:solar:charge_controller_setpoints|voltage setpoints]] are constrained in relationship to each other.   Because of this it may be easiest to configure them in a particular order.((http://techluck.com/cgi-bin/YaBB.pl?num=1486955008))  This order places the configurations in increasing (or equal) voltages the way the controller wants it.  Some [[electrical:solar:charge_controller_setpoints|voltage setpoints]] are constrained in relationship to each other.   Because of this it may be easiest to configure them in a particular order.((http://techluck.com/cgi-bin/YaBB.pl?num=1486955008))  This order places the configurations in increasing (or equal) voltages the way the controller wants it.

 +> Over Voltage Disconnect Voltage > Charging Limit Voltage ≥ Equalize Charging Voltage ≥ Boost Charging Voltage ≥ Float Charging Voltage > Boost Reconnect Charging Voltage.

 Tracer (and the Renogy rebrands) refer to the **Absorption stage as "boost"**.  This is an unforced error; the nonstandard term confuses newcomers and conflicts with the already-existing "[[electrical:solar:charge_controller#mppt|MPPT boost]]" term.  Tracer (and the Renogy rebrands) refer to the **Absorption stage as "boost"**.  This is an unforced error; the nonstandard term confuses newcomers and conflicts with the already-existing "[[electrical:solar:charge_controller#mppt|MPPT boost]]" term.

 The **battery icon** found on many Tracer controllers is unnecessary and misleading.  The manual claims it is a  [[electrical:depth_of_discharge|State of Charge]] meter but there is no guide to reading it.  Since the same voltage can result in different display during charging and non-charging scenarios, it may actually be useful to think of as a **charging indicator rather than state of charge indicator**.  Secessus' unscientific observation reveals these weak correlations: The **battery icon** found on many Tracer controllers is unnecessary and misleading.  The manual claims it is a  [[electrical:depth_of_discharge|State of Charge]] meter but there is no guide to reading it.  Since the same voltage can result in different display during charging and non-charging scenarios, it may actually be useful to think of as a **charging indicator rather than state of charge indicator**.  Secessus' unscientific observation reveals these weak correlations:

 + 
 +EpEver says the Tracer series is not fully lithium compatible since they cannot "activate" Li batteries that have shut themselves down.((https://www.epsolarpv.com/upload/file/1812/EPEVER%20Tracer%20AN_Main_Pres.pdf))  [IMO this is an unnecessarily high criterion which other mfg do not adhere to.  [[electrical:12v:drop-in_lifepo4#mythyou_can_t_charge_li_with_a_lead_battery_charger|Almost any configurable charger can be used for lithium]].  - secessus] 
 + 
 +There is anecdotal evidence that the PC software can configure the controller to stop charging below a given temperature.
