 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.

+===== lithium compatibility =====
+EpEver says the Tracer series is not fully lithium compatible since they cannot "wake up" one whose BMS has shut down.  [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.
