Function
The solar system controller is designed to:
Monitor the state of charge of the battery;
Control the charging process,
Control the connection/disconnection of loads,
Make sure solar system works at max’ possible power.
Features
Charging Voltage is user programmable.
Load Terminal switches Positive side.
Manual load switch with automatic re-start .
Night-Light Functions
Set the two timer schedule programmable for street light application
Performs the MPPT algorithm to harvest the maximum power available from the solar panel.
Caution
Users should seek advice if any of the following situations occur:
The solar charge controller does not appear to function at all.
The solar charge controller or connected cables are visibly damaged.
Emission of smoke or fluid penetration.
When parts are loose.
In the event of such an occurrence, If possible and safe to do so immediately disconnect the solar
charge controller from the solar panels and battery and insulate cable conductors.
--------------------------------------------------------------
MPPT means "Maximum Power Point Tracking". This refers to the type of advanced electronic circuits
used to harvest Maximum Power from your solar panel(s). The Maximum Power Point of PV systems can
vary depending on the prevalent conditions, such as the temperature and solar irradiation levels. This
controller establishes and Tracks the most efficient operating point of the solar panel enabling it to
deliver the maximum available power to the battery.
Operating the controller
The display shows a variety of system data by symbols and digits. Four buttons control all settings
and display windows.
