JN MPPT-C 50~100A Solar Controller User Manual Product features: Advanced MPPT maximum power point tracking technology, and tracing efficiency not less than 99.5%. Compared to common PWM algorithm, it achieves 15% -20% more efficiency. Using high quality imported components and advanced power conversion circuit, the maximum conversion efficiency can reach more than 98%; full-load efficiency can reach 97%. Aluminum metal for structure, JN-MPPT series can be used in all kinds of harsh conditions. R&D with the latest technology, JN-MPPT series can realize the multiple devices in parallel through the RS485 communication interface. With Poly phase synchronous rectifier technology, JN-MPPT series can achieve high conversion efficiency even in low power charging environment. Combination of various tracking algorithm, JN-MPPT series can track the maximum power point quickly. Dual wave and multiple wave tracking technology, when the panels are in partial shade or when a single panel is damaged, JN-MPPT series can still track the maximum power point accurately. Four sections of charging ways: MPPT - equalizing - improving - floating. 12/24/48 V automatic identification function. Support for data storage, storage time can be up to 10 years. With -limiting charging mode, when the input power of the photovoltaic panels is too large, the charging exceeds the rated of the controller. The controller will limit the charging to the rated. With internal detection function, when the controller rises to 75 degrees, the controller will limit the charging to half of the rated. When the reaches 90 degrees, the controller will shut down of charging and output to control the. Through the RS485 communication interface, controller can be connected You can set up monitoring and control parameters etc from the upper machine. The battery compensation function. With a wide range of operating of pv array maximum power point. to the upper machine. With over, over dis, over, over load and reverse connection protection functions. Installation Notes: Picture1 wiring diagram of controller in single operation picture2 wiring diagram of controllers in parallel operation Connect the battery positive and negative electrode cable, load cable and photovoltaic board cable in turn (show as the picture 1). If the parallel use please refer to picture2 way link. Connect the communication cable to 2pin lotus terminal. One end is inserted into the RS485 terminal on the controller, the other end is connected to the converter for RS485. Then connect RS485 converter to the PC. And if the controller is in parallel operation, please connect RS485 communication cables hand in hand to the controller first. Remote probe is inserted into the TEMP terminal of the controller. Turn on the air break switch in the battery side and then in the photovoltaic panels side. Open the controller. The LED lights on the display flash several times and then the controller begin to work. Then close the PV panel air switch, if the PV panel in the charging range, then the controller starts charging. Instructions for use: When the controller is turned on normally, the LCD screen is lit up, the parameters are displayed on the display screen, and the panel indicator light is also on the normal direction.press the corresponding panel button to switch the display parameters and controller parameters of the display screen, as follows: Segment code screen display mode. When the system is powered on, the controller ent ers into standby mode, the battery icon and the loa d icon light up, and related data occur in certain area (corresponding to the monitoring fields, battery is displayed as default setting when open). When load works, load icon lights up, at the same ti me, the arrow between the battery and the load starts running. When load is shut off, load radiance a nd arrow vanish. When Photovoltaic panels are connected, the sun and photovoltaic icon light up, and
the arrow between the battery and the sun/ photovoltaic panels starts running at the same time. If n ot charging, the sun/ photovoltaic panels icon vanish and the moon icon lights up. When press the cor responding button, the corresponding field lights up on the screen. And you can set the related param eters. Each field definition shows in the table below: Field name Definition Function V battery The battery Field lights up, the present battery shows in the display area Photo Field lights up, the Photo voltaic panels shows in the display voltaic V PV area panels I Field lights up, the present battery charging shows in the Charging display area I load Field lights up, the present battery discharging shows in the Discharging display area Under Field lights up, battery dis can be set. when the battery is under, the field flashes. dis Under-R dis Field lights up, battery over dis can be set. recover OVD Field lights up, battery over can be set. when the battery is over, the field flashes.

Error error When alarms, field lights up Set parameters method: There are four buttons on the controller. Buttons definition are, respectively, set (SET), down (DOWN), up (UP), exit (ESC). Functions are as follows: In standby mode, when press the DOWN button, the data of battery (V battery), photovoltaic panels (V PV), the charging (I ) and discharging (I Load) will switch at the corresponding time in the display area;in standby mode, set the system parameter by the SET button. The order for system parameter is under (Under), low (Under- R), over (OVD), over (OVD- R), floating (FLOAT), improving (BCV), equalizing (ECV), the first Time control (Time), the second Time control (Time1), the third Time control (Time2) and light control (L- CON- V). After pressing SET button, according to the parameters order, parameter will increase by 0.1 when pressing the UP button (decrease by 0.1 when pressing the DOWN button). When finish setting a certain parameter, please press the SET button again to save data. When press ESC button in any parameter Setting interface, the controller will return to the standby interface. For some parameters which may affect the system security, you can set them by combined buttons. In standby mode, when press SET and DOWN buttons for 3 seconds at the same time, the system will restore to factory Settings. When press SET and UP buttons for 3 seconds at the same time, Id will show at the top two of the display area. Then press UP or DOWN buttons to set the system Id
(address). Warning: The above settings, on the time control and light control part of this model does not apply. Alarm event: When abnormal conditions are detected, there will be alarm. Alarm events show as below: Events Alarm Alarm Reset Battery Under icon flashes, error icon lights up, Press the ESC button to close the buzzer. When the battery is higher than under buzzer rings intermittently, load is shut under value, the off. controller will resume normal work. Press the ESC button to close the buzzer.

Wiring diagram: In order to install safely, we recommend such a connection order. However, installat ion not in accordance with this sequence will not damage the controller. All the wires should not be twisted together. The power line should be equipped wit h the related wiring terminals. Communication line should be far away from the powe r line in order to prevent interference of communication signal transmission. When the device needs to be moved, please make sure that all the connections are tight. The virtual connection may lead to heat accumulation or even a serious fire. Avoid the battery positive and negative electrode short circuit which may cause expl osion. Never connect the battery terminal of the controller to PV terminal. Otherwise it will burn out the controller. The metal part of the connection terminal is forbidden to touch by hand, so as to avoid electric shock. Do not connect the positive and negative poles wrong. The controller will not work due to reverse connection protection function. The controller power supply is from the battery, so the controller must be connecte d to the battery not directly to photovoltaic system. Installation place should be well-ventilated and dry.
