The Bioenno Power SC-1220JU 12V, 20A {solar lights} Charge Controller is an advanced intelligent multi-stage MPPT {solar lights} charge controller featuring our proprietary CC/CV (Constant Current/Constant Voltage) technology designed specifically for LiFePO4 (lithium iron phosphate) batteries. Designed for 12V systems and handling up to 20A, the controller uses a Buck Conversion Circuit and further uses an MCU to adjust the {solar lights} to a working point in order to make the {solar lights} output maximum power. When the working point of the {solar lights} deviate from the maximum power point, the MCU will adjust the {solar lights} working point based on an MPPT calculation to make the {solar lights} panels provide their maximum power point. Compared with PWM controllers, this MPPT controller can increase the output power of the {solar lights} panels by 5% ~ 30%. The output power increases proportionally by various factors, such as the {solar lights} properties, light intensity, and humidity. This {solar lights} controller is intended for 12V LiFePO4 Batteries Only. Please note that for any {solar lights} setup in which you are using a panel in conjunction with a battery and/or a load a {solar lights} charge controller is absolutely necessary. DO NOT plug a panel directly into your battery or your load! OPERATION Mount the controller on the wall and fasten the screws. Check whether the battery voltage and {solar lights} array voltage is within the requested range. Connect the battery to the controller Connect the load to the load terminal Connect the {solar lights} panel array to the input of the {solar lights} controller To switch the load on, hold the button for 3 seconds. To switch the load off, hold the button for 3 seconds.
