F11 Battery temperature. In this Function the average battery
temperature can be adjusted. The value AU enables the
automatic temperature measurement provided that an
external temperature sensor is connected to the Xantrex
Battery Monitor. Also the temperature readout in normal
mode is enabled. When AU is selected and the connection
with the temperature sensor is lost, four dashes (- - - -)
are displayed and the internal temperature compensation
calculations are made using the default 20 °C value. This
Function can only be set in °C. Use the following
formulas to convert °C to °F : T(
°F
) = (T(
°C
) x 1.8) + 32
and T(
°C
) = (T(
°F
) – 32) / 1.8.

F12 Temperature coefficient. This is the percentage the
battery capacity changes with temperature. The unit of
this value is “%cap/°C” or percent capacity per degree
Celsius. The default setting is 0.5 %cap/°C, which is
typical for most batteries. The setting OFF disables
temperature compensation.

F13 Time-to-go averaging period. Specifies the time window
in minutes the moving averaging filter works with.
Selecting the right time depends on your installation. A
value of 0 disables the filter and gives you instantaneous
(real-time) readout; however, the displayed values may
fluctuate heavily. Selecting the highest time (12 minutes)
ensures that long term load fluctuations are included in
the time-to-go calculations.
