has reached the Low Voltage Disconnect threshold. The Low Voltage
Disconnect has priority above the nightlight function.
The controller recognizes day and night based on the solar array
open circuit voltage. In Programming Menu 3 this day/night threshold
can be modified according to the requirements of the local
conditions and the solar array used.
Both state changes require several minutes of continuous transition
values before making the change. These restrictions avoid false
transitions due to dark storm clouds or lightning.
Low Voltage Disconnect Function (LVD)
The controller has 2 different modes to protect the battery from
being deeply discharged:
1.
State of charge controlled: Disconnect at 11.4 V (at nominal
load current) up to 11.9 V (at no load current). Normal operation
mode for good battery protection.
2. Voltage controlled: Disconnect at 11.0 V fixed setting. Appropriate
if bypass loads draw current directly from the battery.
