charging voltage. The temperature sensor should be close to the battery and away from other heat
sources, otherwise, the controller will have wrong action.
Note: the interface of temperature sensor and exposed copper part of wire shall not contact any
other live conductor, otherwise the controller will be damaged
4) The interface of dry contact is on terminal 11 of controller. If you want to control other equipment,
switch of other equipment can be introduced to dry contact, and the maximum control current of dry
contact shall not be more than 2A.
Note: if the plug of dry contact is connected to the port of temperature sensor, the controller will be
damaged.
5) If you want to connect the controller with a PC, you need a special RS485 communication
option. One end is RJ45 interface, which is connected to terminal 9 of the controller, and the
other end is USB interface, which is connected to the computer.
6) If you want to connect the controller with the mobile phone app, you need a special WiFi or
Bluetooth communication option. One end is RJ45 interface, which is connected to terminal 9 of
the controller to communicate with the mobile phone through wireless signal.
For details of software use, please refer to the 《controller monitoring software operation manual》
6．Start Controller
Note: the controller supports starting the controller from the photovoltaic array end. When the
automatic battery identification function is selected, starting the photovoltaic array terminal first
may make the controller identify the system voltage error.
Before connecting the power supply, please confirm whether the wiring of battery terminal and
photovoltaic array terminal is correct.
After confirming that there is no error, first close the air switch or fuse at the battery end, so that the
controller can recognize the system voltage, and observe whether the LCD is on and whether the
interface is correct. If there is display or alarm status, please refer to 《Fault and Handling》 for
troubleshooting, and then carry out the following operation.
After the battery is connected normally, close the air switch or fuse at the photovoltaic array end. If the sunlight
is sufficient, the charging indicator light of the controller will flash, and the LCD interface will display the charging
state and photovoltaic array voltage, and start charging the battery. When disconnecting the system, please
disconnect the photovoltaic array first and then the battery.
7. Grounding of solar system
Please bear in mind that this type of controller is a common negative design. Therefore, the
negative terminal of battery end and photovoltaic array end in the controller are connected
