The Bioenno Power SC-1220JU 12 Volt, 20 Amp Solar Charge Controller is an advanced intelligent multi-stage MPPT solar charge controller featuring our proprietary CC/CV (Constant Current/Constant Voltage) technology designed specifically for LiFePO4 (lithium iron phosphate) batteries. Designed for 12-Volt systems and handling up to 20 Amps, 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.

Bioenno Power smart technology: the Bioenno Power SC-1220JU features our smart technology intelligent chipset that will auto-adjust this solar charge controller to the correct setting. It's literally plug and play. Attach your panel, attach your battery, attach your load and the solar charge controller will take care of the rest! Our product takes all the guesswork out of portable solar. It works so you don't have to.

This solar controller is intended for 12-Volt LiFePO4 Batteries Only. Please note that for any solar setup in which you are using a panel in conjunction with a battery and/or a load a solar charge controller is absolutely necessary. DO NOT plug a panel directly into your battery or your load!
