For example:
 During cold weather, a battery often requires a higher charging voltage. Some inverters might not
accommodate these higher voltages and can shut down during charging, cutting off power to their loads.
 During hot weather, limiting the RTS Compensation values assures the voltage stays high enough to charge
the batteries instead of dropping too low in reaction to a higher ambient temperature.
 Battery manufacturer specifications indicate not to exceed a certain voltage or battery damage could occur.
In all cases, the batteries should be monitored to ensure they are being charged according to the
battery manufacturer's recommendations.
RTS Compensation has two options available.
 WIDE allows the RTS full control over charging. This option uses the default values for the RTS.

LIMIT sets the minimum and maximum voltages for the RTS.
Pressing the soft key below each option switches between the two options. When the LIMIT option is
visible, a <SET> soft key is available to advance to a screen that allows the user to adjust the settings.
