Also, when the battery is lower than the Low Voltage Disconnect (LVD) for 5 minutes, the load
will be cut off.
When the battery voltage becomes higher than Low Voltage Reconnect (LVR) setting for 5
minutes, the controller will automatically reconnect the load again.

turned on again Z hours before sunrise.
Dusk to Dawn – Load is turned on all night.
Measure Night Length
The load timer options that turn the load on again before sunrise require that the PV charge
controller to measure the length of the night. The default value of night length is 12 hours after
installation (or disconnect then reconnect the battery). The local length of night will take the
moving average of 4 consecutive nights.
If the solar array is disconnected during service, the controller will then record premature night
duration. This wrong night length data will be outdated after another 4 days of normal service.
Alternatively, the above error can be corrected by disconnect then reconnect the battery.
