Protective Function - Ramsond SUNSHIELD PRO User Manual

sun rise, the PV voltage will rise to light control voltage start point, the load
output will be off.
 Manual mode: it will manual on or off by press "OK" button or RC-3
infrared remote control.

Auto mode: This mode with light control + time delay function. There are 2
period working time can be set. After Sun set, load output will be on auto
and work from 1st period. then the load will cut off at the end of 1
Before sun rise, it will work in 2nd period, and cut off when sun rise.
3. Remote Communication (optional)
SDI-P series controllers with optional 485 communication interface for
remote communication through MODBUS protocol, in order to change the
controller operating parameters and status, monitor status of the controller.
Others
Additional interfaces (optional)
SDI-P series controller configuration USB interface is optional interface,
which Supports load output capability of USB-5V1A.
Battery Temperature Sensor

"DS18B20".

Protective function

The controllers have the best protection features to protect the safety and
reliability of the controller.
● Over-discharge protection the battery during discharge, more than the
termination voltage of the
Battery discharge, it may cause pressure within the battery while also
continue to discharge, positive and negative active material damage was
reversible, so that the battery capacity to produce significantly reduced.
When the battery reaches over-discharge protection voltage, the controller
into the over-discharge protection state, turn off the load output, protect the
11
st
period.
