Low Voltage Disconnect Function (LVD)
The CIS controller comes with a sophisticated night-light function. It controls the load output
at night and is widely programmable. Dual load outputs are independently programmable.
There are 3 modes available:
Standard Controller, Dusk to Dawn and Evening/Morning modes.
Night-Light Function
Note: The two voltage levels before/ after the slash are valid for 12 V and 24 V systems respectively.
1 2 3 4
5
6 7 8
The controller recognizes day and night based on the solar array open circuit voltage. This
day/night threshold can be modified according to local light conditions and the solar array used.
"Middle of night" is detected automatically as the midpoint between dusk and dawn, no setting
of a clock is required. It may take several days until the controller has "learned" the middle of
the night precisely.
"Middle of night" may be different from 12:00 midnight depending on your location.
Testing Function
Pushing the test button on the CU (Control Unit) will switch on both load terminals for 2 minutes.
If pressing the button causes a load disconnect event (LVD/SOC, over current) the load will be
switched off.
(1) Controller can not protect itself in a 24 V system; V
panel
-V
battery
is limited to 40 V.
(2) Controller can protect itself, but loads might be damaged.
(3) Battery must be protected by fuse, or battery will be permanently damaged.
(4) The solar panel voltage should not exceed this limit for a long time as voltage protection
is done by a varistor.
