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 [[http://techluck.com/cgi-bin/YaBB.pl?num=1486955008|in a particular order]]. | 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. |

| - "Low Voltage Reconnect Voltage" |
| - "Boost Reconnect" |
| - Then "Float Charge" |
| - Then "Boost Charge" |
| - Then "Equalize Charge" |
| - Then "Over Voltage Reconnect" |
| - Then "Charging Limit" |

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"**.

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 scearios, it may actually be 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**.
