Nightlight Function - Phocos CIS-N-MPPT 100/30 Betriebsanleitung

Nightlight Function

The CIS-N-MPPT 100/30 controller comes with a sophisticated nightlight function. It controls the load output at night
and also is widely programmable.
3 operating modes are available: Standard Controller, Dusk to Dawn and Evening/Morning.
"Middle of night" is automatically detected 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/longitude.
The controller recognizes day and night based on the solar array open circuit voltage.
The day/night threshold can be modified according to your local light conditions and the type of solar array used.
Dimming Function
•
Output voltage 0 V to 10 V relative to battery minus pole (adjust step 1 V, 3% tolerance)
•
Impedance 1,000 Ohm
•
Load hours (load 1 on CIS-CU case printing) and Dimming hours (load 2 on CIS-CU case printing) work together
to effect the dimming function:
