Isolated SmartSolar MPPT RS
9. Float or Storage state. This option switches the relay ON when the charger is in the float state.
10. Day detection (Panels irradiated). This option switches the relay ON whilst the solar panels are providing energy (Day/Night
detection).
Panel voltage High settings
1. Panel high voltage. (User-defined Voltage)
2. Clear panel high voltage. (User-defined Voltage)
This option switches the relay ON when the panel voltage rises above the chosen "Panel high voltage" setting, and switches the
relay OFF when the panel voltage falls below the chosen "Clear panel high voltage" setting. Ensure, of course, that the "Panel
high voltage" setting is greater than the "Clear panel high voltage" setting. These settings must never exceed the maximum
voltage-rating allowed by your MPPT charger.
Battery voltage Low settings
1. Battery low-voltage relay. (The default setting for this is 10.00V) (12V battery assumed)
2. 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.
Battery voltage High settings
1. Battery high-voltage relay. (The default setting for this is 16.50V) (12V battery assumed)
2. 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.
General settings
1. Minimum closed time. (The default setting for this is 0 minutes)
This option sets a minimum-time for the ON condition to prevail once the relay has been switched ON.
An application for this feature, for example, is to set a minimum generator run-time.
