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
6. When the unit is in the default display mode, Pressing the 'enter' button will turn the load ON or OFF
manually. The

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.
