Relay mode
Battery voltage
This option switches the relay in ON when the battery voltage falls too low, This is the default setting
Low
when the relay function is active.
Battery voltage Low settings Battery low-voltage relay. (The default setting for this is 10.00V) (12V
battery assumed) Clear battery low-voltage relay. (The default setting for this is 10.50V) These
settings, which can be user-defined, will cause the relay to switch ON when the battery voltage
falls below the chosen "Battery low-voltage" setting; and will cause the relay to switch OFF when the
battery voltage once again rises above the "Clear battery low-voltage" setting. Ensure, of course, that
the "Battery low-voltage relay" setting is lower than the "Clear battery low-voltage relay" setting. An
application for this feature, for example, is to automatically disconnect a load in order to prevent a
battery from becoming too deeply discharged.
Equalization
This option switches the relay ON when the manual equalization mode is active.
active
Error state
This option switches the relay ON when there is an error.
Defrost option
This option switches the relay ON when the Charger temperature falls below -20 degrees Centigrade.
(Temp < -20 °C)
Battery voltage
This option switches the relay ON when the battery voltage is too high.
high
Battery voltage High settings Battery high-voltage relay. (The default setting for this is 16.50V) (12V
battery assumed) Clear battery high-voltage relay. (The default setting for this is 16.00V) These
settings, which can be user-defined, will cause the relay to switch ON when the battery voltage rises
above the "Battery high-voltage relay" setting; and will cause the relay to switch OFF when the battery
voltage drops below the "Clear battery high-voltage relay" setting. Ensure, of course, that the "Battery
high-voltage relay" setting is greater than the "Clear battery high-voltage relay" setting. An application
for this feature, for example, is to disconnect a load in order to protect it from an over-voltage.
Float or Storage
This option switches the relay ON when the charger is in the float state.
state
Day detection
(Panels irradiated). This option switches the relay ON whilst the solar panels are providing energy
(Day/Night detection).
The switching conditions must be present for at least 10 seconds before the relay will change position.
Setting
Minimum closed
Set by default setting to 0 minutes and is customizable. The minimum-time can be set for the ON
time
condition to prevail once the relay has been switched ON.
An example where a minimum closed time is usefull, is to set a minimum generator run-time.
5.2.4. Streetlight settings
The streetlight function enables the solar charger to automatically control night lighting. It will automatically determine when the
light should be on or off and can control the light intensity.
When the streetlight function is enabled a timer program can be created whereby Sunset, Sunrise as well as Midnight can be
used as anchor points for the timer program. These anchor points will automatically adjust depending on length of the night as
this changes with the seasons.
