Package including:

  1. 1pcs 50a solar controller 
  2. 1pcs temp sensor
  3. 1pcs user manual   
  We recommand :60A with 20mm^2 cable. 
  According to the voltage of battery, controller will adjust the charging current and decide if to supply power to the loads.

CM series controller is a kind of intelligent, multi-purpose solar charge and discharge controller. The family use the fixed LCD display, with a very friendly interface; various control parameters can be flexibly set, fully meet your various application requirements. CM series controller has following features:

1.Image of LCD graphic symbol   
2.Automatic Identification System Voltage level

1.LVD Protection and Treatment
Screen display as shown in the figure that the battery drops below the LVD  protection voltage. The controller has entered the LCD protection state, load circuit  has been disconnected. Use the solar panels recharge the battery or charger when the battery voltage reaches LVR voltage, the controller will resume on the load    power supply, into the normal working state.
2.Solar Panel Fault and Treatment
Symbol flashing represent the controller was not detected solar panels within 24hours. Check if     there is a connection from solar panel, check if there is an open circuit between solar panels with  controller.


1) Ready tools and cables. Encourage you to matching the right cables. Ensure that the current density 4mm2 that is conductive to reducing the line voltage drop. Recommended: 50A with 16mm2 cable. Check weather the installation sites compliance with the relevant safety requirements. Please avoid the damp, dusty, there is a place flammable, explosive and corrosive gases use the controller to install.

2) Install the controller into a fixed vertical plane. See section 5 of the pore size and pore spacing. In order to ensure a good thermal control conditions, please set aside each 10cm below the controller space.

3) As shown on the right, connect the (1) Load,(2) Battery and (3) Solar Panel to the controller according to the order of (1) (2) (3). Pay attention to the load, battery, solar panel and controller of same polarity.

4) Put into the external temperature sensor on the left of the controller (probe port). The temperature sensor should be similar space with battery. (Otherwise, the controller will control the parameters of all wrong temperature compensation.)

5) If you have remote monitoring and control function, please insert one end of the included communication wire on the right of the controller (communication port), the other end to connect to The host computer.

Demolition: To prevent accidents, please order the demolition of solar panels, battery and load disconnect with controller.

Note: Battery polarity will not damage the controller, but you will have a load equipment security risks.
