1．Product introduction
CM series 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 flexibly to
satisfy your different needs. CM series controller has the following features:
●Visual LCD graphic symbol
●Intelligent PWM Charging Mode
●Grade auto switch of system voltage
●Remote Monitoring Function
●Battery reversed protection
●Brief key operation
●Auto temperature compensation
●Accumulative function of charging & discharging AH
●Adjustable charging & discharging parameter
●Settable working modes of loads
●Protection for battery back discharging
●Protection for battery low voltage
●Overloading & short-circuit protection
●Delayed auto restart after overloading
2．Installation Explanation
Installation：
Get ready the related tools & cables. We suggest you choose the appropriate cables to
ensure the current density ﹤4A/mm2 and this is good for reducing cable voltage drop.
Recommendation：30A using 10mm2 cable。50A using 16 mm2 cable.
①Check 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 flammable and explosive gases.
②Install 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 spare 10cm above & below the controller.
③As shown as the right figure, connect the loads, battery and solar panels with the
controller in order. Pay attention to connect the loads, battery and solar panels right.
④Plug the external thermal sensor into the interface of the thermal-sensor on the left
of the controller.
⑤If you need to use the remote monitoring function, please plug one side of the attached
communication cable into the communication port which is on the right of the controller,
and connect the other side with computer.
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.

or turn off the load.
3. Parameter review and setting:
After the controller electrifies right, it will enter into
the displaying interface of battery voltage. This
interface is the main interface of the controller. Press
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 flicker), then it
enters into the setting interface of this parameter.
After finishing setting, press button fr long to exit
the setting interface, and the number stops
