## Description

The Sunflower Solar Power Manager 5V is a high-efficiency solar power management module designed for 5 V solar panels. It features MPPT (Maximum Power Point Tracking) to maximise solar panel efficiency, and supports dual charging via solar panel or USB with up to 900 mA charging current for a 3.7 V lithium battery. The on-board DC-DC converter provides a regulated 5 V 1 A output with ON/OFF control, suitable for powering microcontrollers, sensors, and other low-power devices. Comprehensive protection functions cover battery and solar panel reverse connection, output over-temperature, over-current, and short circuit. Key Features MPPT Algorithm – Constant voltage tracking maximises solar panel efficiency Dual Charging – Solar panel or USB input, up to 900 mA charge current 5 V 1 A Regulated Output – ON/OFF controllable DC-DC converter Comprehensive Protection – Reverse connection, over-charge, short circuit, over-current, and over-temperature Three-Phase Charging – Trickle charge, constant current, constant voltage ESD-Protected USB Connector – Robust USB input Low Quiescent Current – <1 mA standby draw Specifications Solar Management IC: CN3065 Solar Input (SOLAR IN): 4.5–6 V USB Input: 5 V Battery Input (BAT IN): 3.7 V single-cell Li-Po/Li-Ion Charge Current: 900 mA max Charge Cutoff Voltage: 4.2 V ±1% Regulated Output: 5 V, 1 A Output Efficiency (3.7 V battery): 89% @ 10% load, 86% @ 50% load, 83% @ 90% load Charge Efficiency: 73% @ 3.7 V 900 mA Quiescent Current: <1 mA Operating Temperature: −40 °C to +85 °C Board Size: 33 mm × 63 mm Protection Functions BAT IN: Over-charge and reverse connection protection 5 V/USB OUT: Short circuit, over-current, and over-temperature protection SOLAR IN: Reverse connection protection Ideal For Solar-powered environmental monitoring systems Solar-powered robots Small solar street lamps DIY solar power banks Resources Product Wiki
