1. Dimensions 119 mm x 188 mm x 55 mm Weight 0 8 kg Degree of Protection IP32
2. Bioenno Power SC 1220JU SOLAR CHARGE CONTROLLER WITH MAXIMUM POWER POINT TRACKING MPPT THIS CONTROLLER IS ONLY FOR USE WITH 12V LIFEPO4 LITHIUM IRON PHOSPHATE BATTERIES ONLY Solar Charge Controller with Maximum Power Point Tracking OVERVIEW Thank you for purchasing the Bioenno Power SC 1220JU Solar Charge Controller which uses multi stage MPPT technology for use with LiFePO4 lithium iron phosphate batteries The controller uses a Buck Conversion Circuit and further uses an MCU to adjust the solar panel to a working point in order to make the solar panels output maximum power When the working point of the solar panels deviate from the maximum power point the MCU will adjust the solar panels working point based on an MPPT calculation to make the solar panels provide their maximum power point Compared with PWM controllers this MPPT controller can increase the output power of the solar panels by 5 30 The output power increases proportionally by various factors such as the solar panel properties light intensity and humidity 1 2 3 4 5 6 7 OPERATION Mount the controller on the wall and fasten the screws Check whether the battery voltage and solar panel array voltage is within the requested range Connect the battery to the controller Connect the load to the load terminal Connect the solar panel array to the input of the solar controller To switch the load on hold the button for 3 seconds To switch
3. f PV open circuit voltage is beyond the limits Excessive Load Load Light Off Reduce the load current at the load Current Charge Light On output The load may be causing current peaks Short Circuit at the Load Light Off Check if there is a short circuit at the Load Output Charge Light On load output Controller Load Light On Allow the controller to cool down Check Temperature is Charge Light Off for possible causes of overheating Too High Reduce the charge current Make sure the controller is adequately ventilated Inside Load Light On Disconnect the load solar modules and temperature Charge Light On batteries Re install the controller Sensor Error SPECIFICATIONS Maximum PV Voltage lt 70 VDC MPPT Voltage Range 12V to 70V For use with 12V Solar Panels and 12V batteries System Voltage This controller must be used only with 12V LiFePO4 batteries 12V Nominal for 12V LiFePO4 Batteries Maximum Battery Voltage 16VDC for 12V LiFePO4 Batteries Maximum Charge Current 20A Maximum Load Current 20A Charge Control Mode 3 stage Bulk Absorption Float Float Charge 13 8VDC for 12V LiFePo4 Batteries Absorption Charge 14 4VDC for 12V LiFePO4 Batteries Load Disconnection LVD 11 5VDC for 12V LiFePO4 Batteries Load Reconnection LVR 12 6VDC for 12V LiFePO4 Batteries Operation Temperature 10 deg to 50 deg C
