Intelligent Solar Charge Controller
User s M anual
Please read this instru ction carefully before using it.
This controller is a kind of intelligent and multifunctional solar
charge controller. These serial products adopt customized LCD display
screen, which makes the operation on the interface rather convenient.
All the controlling parameters can be reset exibly to satisfy your dierent
needs. This controller has the following features:
1 Product intr oduction
Visual LCD graphic symbol
Brief key operation
Grade auto switch of system voltage
Intelligent PWM Charging Mode
Auto temperature compensation
Adjustable charging & discharging parameter
Settable working modes of loads
Accumulative function of charging & discharging AH
Protection for battery back discharging
Protection for battery low voltage
Overloading & short-circuit protection
Battery reversed protection
Delayed auto restart after overloading protection
2 Installation Explanation
Installation
Get ready the related tools & cables. We suggest you choose the appropriate cables
2
to ensure the current density 4A/mm and this is good for reducing cable voltage
22
drop. Recommendation 30A using 10mm cable 50A using 16 mm cable.
Check whether installation
place accords with the relative
safety rules. Please avoid installing
and using the controller under
the following conditions: wet,
dusty places or places with
ammable and explosive gases.
Install the controller at the
vertical plane. Please refer to
chapter 5 for more detailed info
about the spacing between the
installing holes. In order to make
the controller have good thermal
dissipation, please spare10cm
above & below the controller.
As shown as the right gure, connect the loads, battery and solar panels with the
controller in order. Pay attention to connect the loads, battery and solar panels right.
Plug the external thermal sensor into the interface of the thermal-sensor on the left
of the controller.
Disassemble: To avoid the accident, please dismantle the solar panels, battery, loads
from the controller in order.
Attention: Connecting the battery reversed will not damage the controller, but will
cause safety risk on your loads.

2 . Explanation of button function:
:Interfaces circular toggling button. Use this button can realize the toggling circularly
among the interfaces. The circular order is as follows: as shown as gure 1.
: Parameter adjusting'+'+ button. Besides, under parameter review condition, press
this button for over 5 seconds, and all the parameters will recover to the ex-work
setting state.
:Parameter adjusting'-'button. Besides, at the main interface, this button can turn on
or turn o the load.

3. Parameter review and setting:
After the controller electries right, it will enter into the displaying interface of
battery voltage. This interface is the main interface of the controller. P ress
button to go through the interfaces of the following parameters. If the interface
can be reset, press button for long( 5 seconds, and the number on the
interface starts to icker), then it enters into the setting interface of this parameter.
After nishing setting, press button for long to exit the setting interface, and the
number stops ickering.
