5. If solar module cannot provide current or the current is less than 1Amp for 5 minutes, the controller will 
switch to Night mode and display            in the lower right hand corner.   
 
 
6. When the unit is in the default display mode, Pressing the ‘

enter’

 button will turn the load ON or OFF 

manually. The                         

arrow/lamp symbol will be displayed when the load terminal is ON. 

 

 

 

 

FEATURES 

 

1. PWM Charge control 
 

Depending on the actual battery level, various charging procedures, float charging and boost 

charging are automatically performed. The final charging voltage (Float) is also temperature 

compensated. 

 
2. Deep discharging protection 

If the battery falls below a specified voltage (11.0V/22V), the load output is disconnected preventing 
excessive discharge of the battery. Once the voltage increases to 12.0V/24V the load will be 
automatically re-connected. The set points of the deep discharging protection are predefined and 
cannot be reset. 

3. Temperature Compensation 

ISC3020 has an internal ambient temperature sensor that compensates during the float mode.   

 

 

INSTALLATION 

 

 

Install the controller in a ventilated area away from flammable materials and gases.   

 

The surface should be solid, even, dry and nonflammable. 

 

The battery to controller cable should be as short as possible (1-2m) and be of a suitable diameter 
to minimize voltage loss.   

 

Do not assemble outdoor, the unit should be installed in the way to be protected against humidity, 
dripping, rainwater as well as direct and indirect heat (sunlight). 

 

To ensure the air circulation for cooling an area of 15cm on each side of the unit must be kept free. 

 

The LCD display should be protected against UV rays (e.g. sunlight). Long time exposure to UV 
rays can permanently discolor the LCD. 

 

The solar charge controller may only be connected to the local loads and the battery by trained 
personnel and in accordance with any applicable regulations. 

 

Follow the installation and operating instructions for all components of the PV system. 

 

Ensure that no cables are damaged. 

 

Ensure that polarity of Solar panel/battery/load is correct and use only insulated tools.
